Want to Cut Your Debt? Work Less

Mortgage modification programs create terrible work incentives and are ubiquitous these days, and this is one reason why this recession is so different from previous ones.

In most cases, a homebuyer takes out a mortgage that covers only part of the value of the house he’s buying. In other words, the house a person buys is worth more than the mortgage he owes on it. This means that in the event of borrower delinquency, the lender can, in most cases, obtain his full principal by foreclosing on the house and selling it to a new purchaser.

However, housing prices have fallen dramatically since 2006. By 2008, about 12 million mortgages were “under water” – meaning that market value of the house had fallen below the amount owed on the mortgage. Because of the low resale values, foreclosing on any of those homes will not yield lenders their entire principal; lenders in those cases must rely on the good behavior of the borrowers.

Officials at the Federal Reserve, the United States Treasury, the F.D.I.C., Fannie Mae (most recently, its “Early Workout” program) and Freddie Mac have encouraged lenders in such cases to “modify” mortgages – that is, to accept a stream of payments from the borrowers that is different from the amounts promised when the mortgages were initially signed. In particular, these “modification programs” encourage lenders to reduce mortgage payments so that each borrower’s housing payments (including principal, interest, taxes and insurance) are 38 percent of the borrower’s gross income. The payments are to be reduced for the next five years, or when the mortgage is paid off (whichever comes first).

Of course, a borrower cannot be harmed by the opportunity to have his mortgage payment reduced. But what is economically noteworthy is that the amount of the payment reduction depends on the borrower’s income – the less he or she earns, the more the payment is reduced. For example, a borrower whose annual family income is $100,000 can have her housing payments reduced to $38,000 per year, whereas a borrower whose annual income is $50,000 can have his payments reduced to $19,000 per year.

One implication of the mortgage modification rules is that a family that earns $50,000 less in the year prior to their modification stands to save $19,000 per year for the following five years – or a total of $95,000 on its housing payments! Those are 95,000 reasons to hesitate when looking for a new job, when wrapping up a maternity or paternity leave, or when confronting other job transition situations.

I do not expect every adult among those in the 12 million underwater households to be without a job because of the modification rules. Although modification professionals have specialized in educating homeowners about their modification options, many homeowners probably do not fully understand the mortgage consequences of their earning decisions. Nobody knows the exact numbers, but, even if 90 percent of homeowners were oblivious or uninterested in their modification options, that would leave over a million households that were aware. One million plus workers would make a large dent in the employment statistics.

My previous post reminded readers that productivity has been rising and employment falling in this recession. If approximately one million workers realized that earning income in 2008 was not in their financial interest – and acted on this realization – their actions would have the effect of significantly reducing aggregate employment and hours. As businesses operated with less labor, labor productivity would rise. Maybe the housing crash and mortgage modification that followed have something to do the recession of 2008.

Monthly Productivity

These days Q3 seems like ancient history, so I took a shot at forecasting Q4 productivity from the monthly data. In particular, I took personal income and deflated by the PCE-deflator and the BLS's monthly aggregate hours index. I formed a quarterly dataset:

• BLS hourly productivity for the quarter -- released early in the next quarter


• hourly real personal income (that is, personal income deflated as explained above) averaged for the first two months of the quarter -- available in the last month of the quarter

For the years 2000-8, I regressed log BLS productivity on its lag, a linear time trend, and the log of the personal income variable for the first two months. The last variable had a positive, economically significant, and statistically significant coefficient. That is -- if this relationship holds up -- today we can expect Q4 BLS productivity (not released yet) to be higher because hourly personal income is high for Oct and Nov.

Here is a graph of the two series since 2005. The graph is monthly, so the BLS productivity measure is centered on the middle month of the quarter. The last 3 personal income data points are September (part of Q3), Oct (Q4), and Nov (Q4).

Here's a version with transfers subtracted out of personal income.

Look What Supply and Demand Can Do!

I have taken merely two measurements -- -0.047 (the log change in aggregate work hours from end of 2007 to end of 2008) and +0.009 (an estimate of the log change in labor productivity over the same time frame) -- and the Cobb-Douglas derived demand function, and arrived at SEVEN conclusions:

• There is not downward pressure on wages.
• This recession is fundamentally different than previous ones.
• This recession is the opposite of a real business cycle.
• "Flight to quality" is a symptom, not a cause of this recession.
• This recession comes from a reduced willingness to work, or a labor market distortion, rather than a reduction in demand.
• Labor demand shifts explain no more than 10 percent of what has happened in this recession.
• A fiscal stimulus will be even less potent now than it would have been in previous recessions.

Is there ANY other framework that is even HALF that powerful? Game theory? Behavioral economics? Commenters -- give it your best shot!!

No methodology can be stronger than the data to which it is applied. I am watching the Q4 productivity number closely. I (and, implicitly, the GDP forecasters) do not anticipate a huge productivity decline. But if productivity did decline at a 10 percent annual rate Q3-Q4 or a 5 percent annual rate Q3-Q1 (that's a LOT), then this recession would look more like the previous ones, although even in that case the productivity decline would have come surprisingly late.

How Does Public Spending Stimulate?

Will additional government spending "jump start" the economy? We cannot answer this question without some understanding of how fiscal policy works.

In order to explore this question without assuming the answer from outset, I consider two mechanisms: intertemporal substitution and increasing returns.

INTERTEMPORAL SUBSTITUTION

This is Barro's approach. It says that a temporary increase in public spending crowds out contemporaneous private consumption and investment. Thus, there is no public spending multiplier -- public spending cannot increase GDP MORE than the amount of public spending itself. Public spending does increase GDP because it also crowds out leisure, but it reduces private spending.

This seems to fit the historical data: public spending does seem to reduce private spending.

INCREASING RETURNS

Believers in a public spending multiplier have not been terribly specific about how this works. If I had to formalize their view, I would use some kind of increasing returns. That is, the benefit from working occasionally is GREATER when others are working more. A leftward shift in the labor supply of some persons thereby reduces labor productivity of the others, which causes others to work less.

The question is -- when is the economy in the range of increasing returns? That is, when will (increased) reduced employment (increase) reduce productivity? Arguably there are a number of recessions (including the Great Depression) when reduced employment harmed productivity. In these cases, we might expect that public spending would raise private sector productivity and thereby raise employment by firms that make private consumption and investment goods.

I blame the believers in public spending multipliers for failing to supply us with more details about how the increasing returns works, because this knowledge would help a lot for targeting the public spending in a way that maximized the likelihood that the increasing returns were exploited. However, in this recession this question is moot.

In THIS recession, productivity is HIGH despite the reduced employment. That is, employment seems to have affected productivity exactly as we would expect if there were DIMINISHING returns (that's the Cobb-Douglas model I wrote about yesterday). Thus, even if I could be guaranteed that public spending would be well-timed in this recession AND public spending had a multiplier in previous recessions, I remain doubtful that public spending will have a multiplier in this recession.

We have to accept that, these days, public spending will crowd out private spending.

[Added: I view "increasing returns" as another way of saying "chain reactions" or "coordination failures." That is, if it were so important to work when others do, then why isn't productivity of today's workers lower because of the 2 million workers that left over the last year? I realize that there are "other things going on", but if the "other things" dominate increasing returns in determining productivity, then why wouldn't the former also dominate in determining the fiscal multiplier?]

Labor Market Distortions are Real

Some of the commenters have put up a "perfectly efficient markets" straw man as an argument against the use of supply and demand to understand today's economy. It is probably my fault for not previously elaborating on this point.

I think there are many distortions in the labor market. See, for example, my A Century of Labor-Leisure Distortions or my Public Policies as Specification Errors. Supply and demand continue to be useful in this setting, as long as you recognize that multiple prices exist in the marketplace.

Suppose, for example, that a distortion existed because of an inefficient intermediary. For example, the price of oil might be $50 in Illinois, but $45 in Texas, because oil comes from the Middle East to Illinois via Texas. We can still talk about supply and demand for oil in Illinois. We just have to be careful that the supply of oil to Illinois embodies more than just the behavior of Middle East oil producers and trans-Atlantic shippers -- it also involves the behavior of the Texas intermediary. Or we might analyze the demand for oil from the Middle East, in which case we have to recognize that it is not just Illinois behavior, but Illinois behavior is intermediated by the Texas middle-men. So the Texas middle man appears on the supply side in one analysis, and on the demand size in the other.

Now back to the labor market. None of my posts refer to "wages" -- that is intentional. I refer to PRODUCTIVITY. This means that a whole bunch of things in the labor market appear on the supply side! That includes everything from sticky wages to employer taxes to (hypothetically -- don't lynch me!) worker laziness. You might say that makes the analysis without content because it has an excessively narrow concept of demand -- it might in principle but in practice it has enabled me to distinguish this recession from several others -- other recessions did have labor demand reductions, even under my narrow definition.

One commenter said that bad employer incentives (I guess an employer tax would fit in that category) have to be considered "demand". That comment is incorrect if the analysis treats, as mine does, the "price" as productivity. In my analysis, a payroll tax owed by employers would properly appear on the supply side of the labor market.

IMPLICATIONS FOR "PRODUCTIVITY WEEK"

Because I have put a variety of behaviors on the supply side of the market, the productivity and employment numbers by themselves do not tell us whether sticky wages, employee preferences, bad working conditions, taxes, or some other factor outside the production process caused the "Labor Supply Shift of 2008." The next phase of the analysis is therefore to investigate some of the specific distortions (get a preview of this here, here, here, here, here, here, here, here, and here.

Could Real GDP Rise in Q4?

I think that the forecasts of real GDP growth rates Q3-Q4 of -5 to -6 percent (annualized) are too pessimistic. However, might real GDP actually grow Q3-Q4?

PRODUCTIVITY ANGLE

We have employment and hours numbers for Oct and Nov already saying that aggregate labor hours growth Q3-Q4 (annualized) will be -7 to -8 percent. That means that real GDP growth requires total factor productivity (this is different from hourly productivity I have discussed in previous posts -- TFP is how much GDP would grow if labor were constant) to increase 5 percent or more. That's more than the trend productivity in the recent past, so the odds must be less than 50%.

Productivity growth (for one quarter, at annual rates) has been 5% or more during previous recoveries. It happened two quarters in a row starting 6 quarters after the start of the 1981-82 recession. It happened 4 quarters after the start of the 1990 recession, and again 3 quarters later. It happened 3 times in the year following the start of the 2001 recession. Interestingly, the 2001 recession was a recession with very little quarter-to-quarter productivity decline (this recession has none). This tells me that the odds are not negligible.

Also note that there was a major hurricane and a strike in Q3, which were gone by Q4. This by itself would create a bit of productivity growth.

PERSONAL INCOME ANGLE

I am confident that personal income deflated with the CPI will be higher in Q4 than in Q3, given that it is already so much higher in Oct and Nov than it was in Q3. The GDP deflator tends to be less volatile than the CPI, so personal income deflated by the GDP deflator will likely grow less. However, given that Oct and Nov NOMINAL personal income are a bit higher than the Q3 average and that the GDP deflator will fall Q3-Q4 (albeit less sharply than the CPI), it seems that personal income deflated by the GDP deflator will grow Q3-Q4 about 1 percent = 4 percent annualized.

From this perspective, the question is whether GDP could grow one percent (4 percent annualized) less than personal income. The differences between GDP and personal income include depreciation, retained earnings, net factor income paid to foreigners, and bunch of public sector items (plus estimation error in going from monthly to quarterly). Personal income is about 85% of GDP, so the residual between them would have to shrink by 7 percent (= 28 percent annualized) in order for GDP to grow 1 percent less than personal income. This another reason why I see a significant likelihood that real GDP growth Q3-Q4 is closer to real personal income growth, and thereby positive.

MY FORECAST
My point estimate for real GDP growth Q3 to Q4 is -2.5% (annualized rate). I get this by assuming that TFP follows trend (about 2% annualized; remember that I see that not much is happening with labor demand) and that labor falls 7%. 2 - (7 * labor's share) = -3. Then I add a little because personal income has done surprisingly well in November.

[some hand waving ...] Probability (real GDP Q4 higher than real GDP Q3) = 0.33. Probability (real annualized GDP growth Q3-Q4 < -5%) + .25. That is, the consensus forecasts are too pessimistic, but not impossible.

Monthly Consumption Growth: Highest in 7 years!

I mentioned that the Dec 24 BEA report showed a strong increase in real personal income. Now I notice some interesting patterns with real per capita consumption expenditures from the same report.


The "disaster" here seems to be isolated to durable goods. Of course, we are nauseatingly aware of the automaker woes. But real services (over 60 percent of total consumption expenditure) are actually higher.

The news from Wednesday (ignored, of course, by the press) is that:

• per capita consumption expenditures (all types, deflated by CPI-all) were up in November for the first time since April. This is the largest monthly increase in more than seven years.


• per capita durable consumption good expenditures (deflated by CPI-durables) were flat in November


• per capita services expenditures (deflated by CPI-services) were up in November, for the 20th month in a row


• per capita retail sales (deflated by CPI-all) were pretty flat in November, after 5 straight months of losses

Do we dare entertain the idea that the trough of this recession was in October?

[technical note: I used the CPI for all items to deflate retail sales and PCE - all. The CPIs for durables, nondurables, and services, respectively were used to deflate the components of PCE. I think this is the right approach, but in case you want to see the consumption series deflated with a common deflator (CPI-all), see below. I infer from the monthly inflation rates (Oct-Nov) that fuel costs appear in nondurables: -1.7% (all), +0.0% (durables), -5.1% (nondurables), -0.6% (services) . More on deflators below.]

[added: Today it was reported that

• nominal Dec retail sales are down 5.5-8 percent compared to the same time frame last year. This is a different data source than I used above -- so we have to be cautious with comparisons -- but note that the retails sales data I used have a Nov-Nov change in nominal retail sales of -5.9 percent.


• amazon.com had the best holiday season ever.

So today's data is consistent with the expectation that December's consumption will be as strong as November's.]

[Added Dec 27: Thanks Tegwar for pointing out that the BEA has monthly PCE deflators. The graph below uses them. The news items based on the various PCE deflators are:

• per capita consumption expenditures (all types, deflated by the PCE-all deflator) were up in November for the first time since May. This is the largest monthly increase in two years.


• per capita durable consumption good expenditures (deflated by PCE-durables deflator) increased in November


• per capita expenditures (deflated by category-specific PCE-deflator) were up in November for all three consumption categories


• per capita retail sales (deflated by PCE-all deflator) were pretty flat in November, after 5 straight months of significant losses

Rising Productivity with Falling Employment

Everyone seems to think it is so easy to explain why productivity can rise when employment falls. It is -- IF labor demand is stable. The observation that "marginally" productive workers are the first fired is exactly what it means to move ALONG the labor demand curve.

The real question is how do you modify your prediction for the previous severe recessions -- when productivity FELL?! Here's what I say: that's when demand shifted more than supply.

This is why I have spent a whole week asking: why does the labor demand curve shift so little in this recession, and so much in previous (severe) ones?

Merry Christmas!

Merry Christmas!!!!!!!!!

Economics Lesson from the University of Chicago’s U.S. Senator

Copyright, The New York Times Company.

President-elect Barack Obama was not the first University of Chicago professor to serve in the United States Senate. More than 50 years prior, a professor from my department named Paul Douglas became a United States senator representing Illinois.

In his life as an economics professor, Professor Douglas wrote about the supply and demand for labor. Some of his techniques can lead us to a surprising conclusion about today’s recession: The recent decrease in employment may be less due to employers’ unwillingness to hire more workers, but more to workers’ unwillingness to work.

As you’ve probably heard, employment has been falling over the past year. After peaking in December 2007, employment fell 1.4 percent over the next eleven months. Hours per employee were down, so that total hours worked were 4.7 percent below its upward trend over the prior 36 months. Explanations for the decline — like most everything in economics — can be classified in two ways: supply or demand.

In many recessions, the demand for labor gets much of the blame. The demand explanation says that, with orders for their products down, many employers have trouble finding productive uses for their employees. Some employees are then let go. In this view, productivity – the amount produced per hour worked – should decline because reduced productivity is one of the driving forces of layoffs. Gross domestic product thereby declines for two reasons: fewer workers and less productivity per worker.

Indeed, hourly productivity did decline in the 1981-82 recession, falling three of four quarters for a cumulative peak-to-trough decline of 2.3 percent. Productivity fell faster and longer during the Great Depression.

The second type of explanation is reduced labor supply.

Suppose, for the moment, that people were less willing to work, with no change in the demand for their services. This means that each worker who remains employed would have to be more productive because employers have to produce with fewer workers.

Of course, people have not suddenly become lazy, but the thought experiment gives similar results to the actual situation in which some employees have bad incentives to take jobs and some employers have bad incentives to create them.

Professor Douglas gave us a formula for determining how much output per work hour would increase as a result of a reduction in the aggregate supply of hours: For every percentage point that the labor supply declines, productivity would rise by 0.3 percentage points.

As mentioned above, in 2008, labor hours have fallen 4.7 percent below trend. According to Professor Douglas’s theory, this means productivity should rise by 1.4 percent above trend by the fourth quarter.

So let’s take a look at the numbers. Unlike in the severe recessions of the 1930s and early 1980s, productivity has been rising. Through the third quarter of 2008, productivity had risen six consecutive quarters, with an increase of 1.9 percent over the past three, or 0.7 percent above the trend for the prior twelve quarters.

Because productivity has been rising – almost as much as the Douglas formula predicts – the decreased employment is explained more by reductions in the supply of labor (the willingness of people to work) and less by the demand for labor (the number of workers that employers need to hire).

Why would some persons have worse incentives to take jobs (and employers worse incentives to create them) in 2008 than they did in 2006 or 2007?

I will tackle that question in my next [New York Times] post, but even without a specific answer we learn a lot about today’s recession from the conclusion that labor supply – not labor demand – should be blamed. First of all, it suggests that a fundamental solution to the recession would encourage labor supply (perhaps cutting personal income tax rates, so people can keep more of their wages), rather than tinker with demand.

Second, the recent supply reduction may be more short-lived than the demand reductions of past severe recessions. In particular, as people adjust to the reality of depleted retirement accounts and vanished home equity, many of them will decide to make up for some of the shortfall by working more and retiring later.

On another note, the Department of Economics at the University of Chicago does not conform to stereotypes: Professor Douglas ran for senator on the Democratic Party ticket and was occasionally accused of being a socialist. I teach his formula frequently and with admiration.

Real Personal Income is Higher than Ever

[all of the statistics below are seasonally adjusted by the BEA or BLS]

Today the Commerce Department released its estimate of November nominal personal income, 12.1638 trillion dollars (at annual rates).

ECONOMICS 101: DIVIDE BY CPI

The press is emphasizing that the figure is 0.2 percent less than in October. But let's not forget that the BLS reported that consumer prices were down 1.7% over the same time frame. That means a real personal income INCREASE of 1.5% in just one month!

We can argue about how exactly to deflate, but no resolution of that argument is going to change this 1.5% gain into a measure that screams disaster.

I'm not sure why the Commerce Department does not report real personal income, although at the bottom of its report it does show real disposable personal income, which was 1.0 percent HIGHER in November than in October. That's their calculation -- not mine -- so don't blame me from ruining your "economic disaster" parade.

Today's Commerce Department shows data back to April: over that time frame, personal income deflated by CPI was highest in November. I am pretty sure that makes November higher than ever!

REAL PER CAPITA

If you like things in per capita terms, November real personal income (at a monthly rate) was $3311.61 per person. That's the second highest ever, with the first highest being $3311.79 per person in May. That's right, we missed the real per-capita record by 18 CENTS per person. Enough said!

GUESS AT Q4 REAL GDP

The experts are saying that real GDP (at quarterly rates) will be more than 1 percent lower Q4 than Q3. Are any experts reading this? Can they explain to us why they have that expectation, given that October real personal income (quarterly rate) EXCEEDED the Q3 real personal income by 1.2 percent and November EXCEEDED it by 2.8 percent? Are you predicting that real personal income will fall more than 10% in just one month, in order to bring the Q4 average down that far? Or are you predicting a huge departure between the growth rates of real personal income and real GDP?

I am admittedly an amateur at high frequency forecasting (it has less to do with the basic economic forces I have been emphasizing, which may take a couple of quarters to work out), but there are enough significant inconsistencies with the experts' forecasts that I have to issue my own:

• Q4 real (and seasonally adjusted) personal consumption expenditure will fall less Q3-Q4 than it did Q2-Q3.
• Q4 real (and seasonally adjusted) GDP will fall less than 1.0% (that is: less than 4.0% at annual rates) Q3-Q4, and may rise.
• Q4 labor productivity will be higher than Q3's (that is, productivity growth Q3-Q4 will not be negative).

The So-Called Participation-Hours Dichotomy

Here's a peek at some (no so pretty) Chicago Economics department politics. Coleman wrote a dissertation at Chicago in the 1980s saying that most of the business cycle was on the "extensive" or "participation margin" rather than the "intensive" or "hours margin." Professor Heckman wrote that this was one of the important lessons in labor economics.

I disagree. Participation and hours, as usually measured, are hardly conceptually distinct. Nor do my calculations for previous business cycles show the stark contrast that Coleman's did.

For this recession, hours per employee per week seem to have fallen in about the same percentage as the number of employees.

The so-called participation-hours dichotomy is much ado about almost nothing. Let's just say that labor supply slopes up and get on with it.

[The sometimes important issue of imputing wages for persons who do not work (and times not worked within person) is often confused with the supposed conceptual distinction between participation and hours. I explain here why we should not confuse these].

Supply-Demand Accounting for the 2008 Recession

Let's look at labor quantities and productivity now and at the end of 2007 (when employment peaked and NBER says that the recession started):

• From Dec 2007 to Nov 2008, aggregate hours are down 4.7 percent relative to the trend for the prior 36 months


• From 2007 Q4 to 2008 Q3, productivity per hour is UP 1.9 percent, or 0.7 percent above the trend for the prior 12 quarters.


• Productivity numbers are not in yet for 2008 Q4, but let's suppose that (as compared to 2007 Q4) they are 0.9 percent above trend (that is, continuing the pattern of the prior three quarters).

The graph below is a supply and demand representation of the situation, based on the assumption that labor demand has an elasticity of -0.3 --> with stable labor demand, a 4.7 percent labor reduction would be associated with a 1.4 percent labor productivity increase.

We see that Dec 2008 is explained mainly by a supply shift. The magnitude of the supply shift is not unusual as recessions go. The lack of a significant demand shift is.

I expect that economists and others will find this conclusion very controversial, even though this is exactly the kind of accounting that Murphy and Katz did on their well accepted paper on the skill premium. Indeed, their method is better applied here because we know more about the aggregate labor demand elasticity than we do about the cross-skill elasticity of substitution in production.

[Technical Note: I stretched the price axis for the purposes of illustration. If drawn to scale, the demand shift is even smaller relative to the supply shift than shown above. Assuming that labor demand follows Cobb-Douglas with 0.7 labor's share and the elasticity of labor supply is less than 2, then more than 90 PERCENT of the reduced quantity of labor is due to a labor supply shift.]

Flight to Quality -- Cause or Effect?

Professor Lucas is a strong advocate.

I agree that there is a flight to quality. Professor Lucas says that one way that people attempt to buy safe securities is to spend less on consumption goods. That makes sense -- but the same logic implies that people should work harder (earn more) as another means to accumulate those securities. The facts show that people are working less. Barro and King (1984) explained it best -- the basic puzzle of recessions (this one included) is that consumption and leisure move in opposite directions. Wealth effect and intertemporal substitution effect explanations of recessions (Professor Lucas' story is one example) imply that they move together.

That's why I believe that the "flight to quality" is a symptom rather than a cause.

Professor Lucas arrives at the conclusion that the Fed should print money. Despite the arguments above, I agree that such a Fed policy would do more help than harm.

GDP Revision: Productivity Perspective

The Commerce Department regularly updates its national accounting estimates. Today they reported that GDP fell 0.5% at an annual rate 2008 Q2 to 2008 Q3, which is the same as it had previously estimated for that time period.

Employment fell 1.1 percent at an annual rate over the same time period. Aggregate hours worked fell 2.2 percent at an annual rate over the same time period. With GDP falling less than labor, we conclude that productivity was rising -- despite the Boeing strike and the major hurricane that occurred in Q3.

Mankiw's Teaching on the Fiscal Stimulus

Professor Mankiw explains it well here. Now I understand why his textbook passes the market test!

A Labor Market Tautology

By the NBER definition, a recession occurs when employment falls.

Employment falls when either labor supply shifts to the left, or labor demand shifts to the left, or both [for these purposes, "labor supply" includes any labor market distortions, such as income taxes and minimum wages]. This is a tautology -- it is true regardless of what is the "right" model of the economy, and regardless of what really caused the recession.

Thus, it is no surprise that recessions tend to have (a) negative productivity growth and (b) leftward shifts of the labor supply curve. The former is related to labor demand and the latter to labor supply. If we just focus on employment reduction events, it is no surprise that the average event has both reduced labor supply and labor demand.

What would be VERY interesting is a recession that occurred with only ONE of these changes. The prototypical real business cycle featured productivity shocks and a stable labor supply function (more precisely, a labor supply function that shifted ONLY due to wealth or intertemporal substitution effects) -- in other words a real business cycle recession is one in which the reduction in employment is largely blamed on labor demand. That is why commentators on (critics of?) the real business cycle model have repeatedly illustrated that employment fluctuations have to be explained in part by labor supply shifts (Barro and King, 1984; Hall, 1997; Mulligan 2005), and not just productivity shocks.

This recession may be one of the first ever that can be explained by ONE of those changes. But, contrary to prototype real business cycle, the ONE change is in labor supply without much reduction in labor demand. The basic methodology of real business cycle theory may apply well to this recession -- as long as we put the shock on the labor supply side of the market and hold productivity constant.

Labor Productivity Week

This week I have a several blog entries on productivity and employment. Wednesday's entry will be shown on the New York Times Economix Blog. Plan A is that I will continue to make Wednesday entries there.

Labor productivity tells us a lot about what is happening in the U.S. economy right now.

Inflation article in yesterday's Tribune

Click here.

IMO, it somewhat overstates the benefits, but I agree in spirit. The article is exactly right that inflation is the only housing price stimulus plan that would not add further to the housing glut.

Ford's Sentiment Tells All

Of the big 3, Ford is said to be the most solvent. Does Ford want its weaker competitors to fail or survive?

In many industries, each producer fantasizes that some of his competitors would go out of business. With their failure, the surviving producers can raise prices, cheaply acquire assets for expansion, and negotiate better deals with firms that supply inputs to the industry.

Notably, Ford has (apparently) not aspired for failures by GM or Chrysler and the aforementioned advantages that would accrue from their failures. Ford has actively participated in the lobbying efforts and -- aside from sending their CEO on the first DC trip in a private jet -- have missed many opportunities to sabotage the bailout.

This fact tells us a lot about the bailout's impact. Ford must believe that a bailed out GM and Chrysler would charge higher prices than would the manufacturer(s) who would serve GM and Chrysler customers after they failed. It's easy to see why Ford might believe this: a GM or Chrysler failure would break union contracts with those two manufacturers. Ford would still be tied to its contract as long it remained solvent, and thus would find itself competing with unionless manufacturers. Ford would benefit by a bailout of its competitors because the bailout would prevent its competitors from reducing costs.

If the Bush administration were loyal to the consumer, it would have asked Ford what kind of bailout Ford wanted for GM and Chrysler -- then did the opposite! In fact, the Bush administration did pretty much what Ford wanted, and thereby revealed its loyalties.

Our Weird Recession

Professor Nunes kindly sent me his illustration of productivity growth for past recessions (I believe that these are the percentage growth rates from the quarter indicated to the quarter one year prior). Productivity growth is usually negative in recessions. He shows the recent recessions as exceptions, although those recessions also show some negative quarter-to-quarter productivity growth (not shown below) -- today's doesn't (yet).

Productivity is Still Growing

It looks like employment will be one percent lower in 2008Q4 than it was in 2008Q3. There is not much uncertainty about this, because October and November employment are already known.

Work hours per employee will also be lower -- maybe also about one percent. Thus, total work hours will be 1-2 percent lower, probably closer to 2 percent.

Productivity growth is the percentage change in GDP minus the percentage change in total work hours. I have seen forecasts that GDP 2008Q4 will be 1.25 percent lower than for 2008Q3. Thus, the forecasts imply further productivity GROWTH. Productivity also grew 2007Q4 through 2008Q3 (about 1.9 percent). The fact that we are having a recession while productivity is growing tells us a LOT about why we have a recession, and why it is so different from the 1981-82 recession or the Great Depression. More on this over the next week....

For those 136 million who still have jobs, productivity growth is VERY good news because productivity determines how much you ultimately get paid.

I'm Glad that Gas is Cheaper

The CPI fell 1.7 percent between October and November. That's a lot -- if that continued for 12 consecutive months, the annual inflation rate would be -18 percent!

However, essentially all of the drop was reduced energy prices. As a net oil importer, the U.S. is better off when oil is cheaper relative to the goods that we produce.

Nevertheless, I would like to see the Federal Reserve take bigger steps to keep INflation going. Inflation will alleviate some economic problems; prolonged deflation will aggravate them.

Will Today Live in Infamy?

Today the Streamlined Modification Program, sponsored by Freddie Mac, Fannie Mae, and other federal agencies, goes into effect. It modifies mortgages so that the monthly payments are no more than 38% of borrower income. In other words, borrowers with more income have to pay more; borrowers with less income have to pay less. Indeed, a borrower that is able to earn $1000 extra on his own may, as a result of earning it, ultimately add more than $1000 to his mortgage payments.

This is a sure-fire recipe for removing the incentives for people to work and earn income and thus an effective way to REDUCE employment in the economy.

Until recently, the agencies and a number of banks were modifying mortgages for delinquent borrowers (about 10 percent of mortgages are either delinquent or in foreclosure). "Fannie Mae announced [last] week that homeowners who make their mortgage payments on time but who are struggling financially will be eligible for mortgage modification." (quote from USA today, referring to a December 8 Fannie Mae announcement). This WIDELY expands eligibility and thereby widely expands the reach of these awful incentives.

U.S. 2008: Richest Year in World History?

It is very likely that the U.S. will have the most real GDP per capita in its history in 2008, despite the fact that the entire year will be spent in recession (by the employment definition).

Cross-country comparisons are not easy, and oil countries have had some very good years, but arguably the U.S. has the most GDP per capita in the world. U.S. 2008 might be the richest year in world history thus far!

Remarkably, one can have a reasoned debate as to whether U.S. 2008 was the richest in world history, but at the same time the news media characterizes 2008 as a year of "economic disaster"! Well, I'd rather have this "disaster" than, say, going back to 2004 GDP per capita.

Could it be that declarations of disaster are used as an excuse to steal our tax dollars?

CALCULATIONS

2007 GDP (chained 2000 $) was $11,524 billion. 2007 population (July) was 301,621,157 --> real GDP per capita was $38,207.

Through Q3, 2008 GDP was $8,771 billion (seasonally adjusted by the BEA). 2008 population (July) was 303,824,640 --> 2008 produced $28,870 per person already through Q3. That means only $9,338 per capita ($2,837 billion in aggregate) needs to be produced in Q4 to break the 2007 record. In other words, if Q4 is within 3 percent of Q3, we break the record. Even the most pessimistic forecasters admit that Q4 real GDP will be greater than that.

[added: there is plenty of room to debate whether a couple of oil countries were momentarily richer (per capita) than the U.S. My point: the fact that you can debate these things shows that "disaster" is not an accurate description of 2008]

Don't Blame Greenspan

I attribute the housing boom to optimism (whether it was warranted is another story). Others blame Greenspan. See a debate on this topic here.

Mortgage Modifications' Implicit Tax

Mark Lieberman of Fox Business News has an article about the feedback effect of mortgage delinquencies on unemployment.

I spoke to Mr. Lieberman, who explained to me how he used to work for a bank. He explained that it was common banking practice in previous recessions to modify mortgages according to borrower income. So maybe my theory applies not only to 2008 and 1933, but also a number of recessions in between?!

Please Remember Neglected Children During the Holidays

The theory of supply has been severely neglected this year. Read here where I beg Professor DeLong to remember supply.

Wow! Crook County Fitzmas

The Democratic Party enjoys quite a monopoly in Cook County. I am glad to see that the U.S. Department of Justice is doing something to prevent the party from charging us citizens too much.

• Rostenkowski stole postage stamps.
• Ryan stole drivers' licenses.
• Blagojevich allegedly stole a Senate seat.

What's next?!

[added: some Nixon fans say that Mayor RIchard J. Daley stole the presidency]

Hindsight: Taxpayers ripped off?

The AP reports that the preferred shares of banks purchased by the Treasury have lost $9 billion in value already. On the surface, it would seem that taxpayers over-paid.

However, I have explained earlier that taxpayers are among bank shareholders, and the Treasury funds went straight to those shareholders. In hindsight, those lucky shareholders received a good price for the stock they sold to the Treasury.

This is not a situation where taxpayers were ripped off, but rather a situation where some taxpayers got a bad deal and others got a good deal. Moreover, if you are among the former it is your own fault, because you could have sold bank shares when the Treasury was buying.

When Will Housing Construction Resume?

Housing construction will resume when housing prices are anticipated to be at or above construction cost for the duration of time it takes to build a house.

OK, when will housing prices be anticipated to be at or above construction cost for the duration of time it takes to build a house? That will occur when the demand for housing is expected to exceed the current stock of housing. The U.S. stock of housing, measured in year 2000 prices, was $12.9 trillion at the beginning of this year. If demand continued to follow the trend of the 1990s (a period without a housing boom), the demand for housing at year 2000 prices would have been $12.6 trillion at the beginning of this year. In other words, we need a sustained demand increase of 3 percent in order for the houses we have to be worth construction cost.

During the 1990s, demand increased an average of 0.2% per month (2.4% per year). At that pace, demand would reach $12.9 trillion (today's housing stock) by April 2009. Below is a chart showing actual housing and 1990s trend housing. Notice from the chart that the trend exceeds this year's actual value before the beginning of 2010.

If demand returned to the 1990s trend, there a couple of reasons why housing construction could resume sooner than April 2009. First, some of the housing built during the 2000s boom may have been built in the wrong places, so the current housing stock is over-valued at year 2000 prices. Second, although in hindsight we can say that housing demand that was high enough to sustain boom time prices never materialized, housing demand might still have increased beyond the 1990s trend (that is, the housing boom was exaggerated but based on something real, wasn't it?). Third, houses are depreciating for the usual reasons, plus some additional neglect due to the foreclosure process.

Of course, we are in a recession and a financial crisis now, which may reduced demand below the 1990s trend. Also, the actual stock has not been frozen at $12.9 trillion because a bit of building has occured this year. I expect the size of this demand reduction and the contribution of year 2008 construction to be small, and therefore expect to see housing construction resume next summer, if not earlier.

EPILOGUE: WHEN WILL HOUSING PRICES RETURN TO BOOM LEVELS?

Boomtime housing prices were much above construction cost, and therefore much above where I expect them to be next summer. It will take either general inflation or another housing boom for housing prices to return to boom levels. I and some other economists have recommended some inflation, but if that recommendation is not followed and inflation rates continue in the 2-5%/year range, it will take a number of years for housing prices to return to what they were in 2005 or 2006.

This Week's Employment and Productivity Reports and the Outlook from Here

In October I predicted that U.S. nonfarm payroll employment would never fall below 134 million (a level that would make this recession almost as deep as 1982). This prediction still makes sense to me, even though I did not anticipate that the Treasury and the Fed would themselves contribute to labor market damage.

Friday's employment report put nonfarm payroll employment at 136 million, having fallen 0.5 million in a month. Thus, I am predicting that we will not have four consecutive months like last month.

Productivity is what ultimately determines employment, and that looks good so far. On Thursday we learned that output per hour grew at 1.3% (annual rate) from 2008 Q2 and Q3, which is similar to the overall pace for 2007 and exceeds the pace for 2006. For the entire calendar year 2008, it looks like productivity will have grown more than it did for either of the prior two calendar years. By comparison, productivity growth was NEGATIVE in 1982 and (according to Cole and Ohanian) in EACH of the years 1930-33.

You may have noted the contrast between this year's employment performance and GDP performance. When productivity grows, output can grow even while employment falls. We are in a recession (and have been since late 2007) by the employment definition (NBER uses this) but not yet by the GDP growth definition. We likely will finish 2008 with more GDP than in any year in history, yet less employment than in 2007. The GDP and productivity performance is quite different from "severe recessions." What is severe about the 2008 economy is the news coverage, and the assault on the taxpayer!

Mortgage Arithmetic Behind Tribune Article

Some Tribune readers asked to see some arithmetic. I posted some mortgage arithmetic here in an Excel spreadsheet.

Although this example shows that you would actually have LESS money to spend if you found a job quickly, please note that this is not the entire point. The point is that a large fraction of the money you generate by working goes to the bank. That's why its like a tax: earn more = pay more to bank; earn less = pay less to bank. Yes, a person paying a 50% tax can spend more if he works more. But he has half the incentive to work than he would have if he paid a 0% tax.

In a normal situation, your decision to work has nothing to do with what you pay the bank. You either pay in full or give up your house, regardless of how much you work and earn. But 2008 is not a normal situation.

Homeowners are No Dummies

I expect homeowners to take deliberate steps to make themselves more forgivable: steps that include earning less income and going delinquent on mortgage payments.

There is always a small group of economists who dismiss the importance of incentives like these, and think that the vast majority of people are not really paying attention. I find their attitude to be arrogant, but -- more important -- contrary to the evidence. Bloomberg reports that 1 in 10 homeowners are in foreclosure or delinquent on their mortgage payments. Sure, some of them lost their jobs for reasons beyond their control (employment is down 1.4 from its peak). But not TEN PERCENT! The vast majority of those delinquent or in foreclosure continue to be employed.

The more important factor behind delinquent mortgage payments is that homeowners can get away with it. Yes, they risk losing their house. But a number of people find that preferable to overpaying for the house. They assume, and rightly so, that they can find another house, and find one cheaply.

The Income Tax Hike of 2008

I wrote about it today in the Chicago Tribune.

Fundamental Origins of the Housing Boom and Bust

Professor Larry White says it was pro-housing regulatory and lending policy. Professor William Black said that Corporate CEO's had bad incentives.

I say that it might have been the anticipation of technological or taste change that did not materialize as quickly as we thought. I don't think the high and rising housing prices, and the fairly stable housing rental rates, are consistent with either Professor White's or Professor Black's theory.

We'll see what Professor DeLong has to say.

By the weekend, you will be able to read all four essays here.

Bernanke is Unwittingly Damaging the Labor Market

Federal Reserve chairman Bernanke wants banks to reduce homeowners' mortgage payments, but do so as a function of homeowner income. I have already explained that this gives homeowners no incentive to earn income. If widespread enough, this forgiveness policy can turn a recession into a depression.

Two weeks I warned about this on my blog and in an NBER working paper.

I am not surprised that Bernanke does not read this blog. I can also understand why he makes this mistake -- his academic work was about how loan overhangs prevented new loans from getting made. But he misses that, even if new loan markets were functioning well, the old loans themselves do damage because they encourage people to try to become forgiveable. If he wants debts forgiven, they should be forgiven without regard for borrower circumstances.

Crowding Out -- Isn't it Obvious?

COMPETING THEORIES

Some economists promote the fantasy that an "exogenous" increase in spending in one receiving sector can increase spending in the other sectors. Supposedly the employees in the receiving sector take their paychecks to spend in other sectors.

By the same logic, an "exogenous" reduction in spending in one receiving sector can reduce spending in the other sectors.

This is a fantasy because it neglects supply. If supply is a constraint on output -- that is, to get more output additional employees and capital have to be encouraged to produce more -- then added spending in the receiving sector pulls resources out of the other sectors.

One application of this logic is to the public sector: the debate is whether public spending would increase or decrease private spending.

TESTING THE THEORY WITH DATA FROM 2008

Another application of this logic is to the residential sector: does residential spending increase or decrease nonresidential spending? Here it is easy to see the importance of supply -- see the figure below.

When housing boomed, nonresidential construction spending fell (despite the fact that the housing boom was increasing the prices of construction labor and materials) -- almost dollar for dollar!

When housing crashed, nonresidential construction spending ROSE (despite the fact that the housing crash was reducing the prices of construction labor and materials), about 15 cents on the dollar. Note that, according to the NBER, some of the nonresidential increase occur ed during a recession.

Another fascinating property of this episode is that the shocks to spending are on the order of magnitude (100s of billions of dollars) of the kinds of fiscal stimuli being recommended by some economists.

When interpreting what is above, we need to recognize that a large sector is omitted -- the non-construction sector. For this reason, the calculations above underestimate of the aggegate supply effect of housing spending on nonresidential spending (Take, for example, accountants. A housing boom pulls accountants into work for construction businesses, which leaves fewer accountants to work for non-construction businesses.). But they also underestimate the aggregate demand effect, because the housing construction workers are taking their paychecks and spending some of it on non-construction items. In any case, the supply effect is easy to see -- the housing construction boom did not take place with resources that would have otherwise been unemployed and the housing bust did not release resources entirely into unemployment.

Interestingly, this single graph both helps the case for crowding out and helps the case FOR Obama's fiscal stimulus. More on that paradox to come...

Depression Deception

The AFP reports that Federal Reserve Chairman Bernanke says that today's situation is "no comparison" to the Great Depression. I agree that there are many fundamental differences.

However, earlier President Bush was told by Bernanke (and Paulson) "if we don't act boldly, Mr. President, we could be in a depression greater than the Great Depression." I am not surprised that persons in the finance industry used scare tactics to increase their power and subsidy rate. I am surprised that they admitted it, and the admissions came so quickly.

Public Spending will Crowd Out Private Spending

The concern right now is that the private sector is shrinking, or at least not growing like it used to. My added concern has been that the new Administration would sell a "fiscal stimulus" based on the fantasy that government spending actually stimulates private spending (perhaps along the lines that Professor Krugman is selling the fiscal stimulus), when in fact public spending crowds out private spending.

I have been relieved to see that new Keynesians like Professor Mankiw are candid about the possibility that public spending reduces private spending.

I will write more as inauguration day approaches, but to a first order approximation, I think that public infrastructure spending may be a good idea, or at least not such a bad idea, even though it wouldn't stimulate the private sector.

Colleges Accused of Collusion, Again

Professor Sanderson explains.

Flashback: Professors Chari, Christiano, and Kehoe debunk 4 myths

NEW WORK

Last month I pointed readers of this blog to empirical work by Professors Chari, Christiano, and Kehoe (hereafter, CCK). Some commentators claim that new work since then overturns their findings. That commentary is incorrect. To see why, let's review.

CCK found that most investment (they offered a rough figure of 80%) is financed without bank lending. I said the same in my New York Times article. The new study does not dispute this finding, which is absolutely fundamental for understanding how the banking crisis impacts us.

Second, CCK found an increase in bank lending. The new study does not dispute the increase, but notes its composition: bank customers were drawing on previously established credit lines. While the additional evidence provided is quite useful, please remember that I had already suspected as much. More important, this point about composition in no way refutes the fundamental claim that banks are still lending to many types of customers.

PRIOR SUSPICIONS
At the time CCK released their important paper, my take was (read in full here and here):

"Professors Chari, Chrisiano, and Kehoe have now looked a variety of Federal Reserve Bank data. From the data, they conclude:

1. "The claim that disruptions to the banking system necessarily destroy the ability of nonfinancial businesses to borrow from households is highly questionable."
2. The data show no decline in bank lending to nonfinancial business.
3. Nonfinancial business are issuing commercial paper at quite low interest rates.
4. The volume of interbank loans continues to be quite high.

... I am wondering whether (2) is bank-driven or customer-driven." and

"I suspect that much of the loan increases are "passive" -- that is, banks had already committed to customers that they could have access to credit and those customers took full advantage (i.e., it is the bank customers who are hoarding liquidity). Likely that is why deposits increased so much: bank loan customers just turned around and made deposits. Nevertheless, it is notable that banks honored their commitments, and then stand to make an easy profit as their customers receive less interest on the deposits than they pay on the loan." (italics added)

Now more study has reinforced the conjecture I made a month ago: that bank lending increased because of customers' drawing on pre-existing credit lines. Authors of the new study acknowledge that the data do not prove the existence of a credit crunch beyond a small segment of borrowers, but might well be explained by customers' lack of willingness to borrow.

MISGUIDED DEBATE

In any case, my prior analysis implies that the backlash against CCK is misguided. First, the real banking problem (from the perspective of the nonfinancial sector) is with settling the old loans, not making new ones. Second, even if the banks' troubles caused them to lend less, you might not be able to detect this with comparisons between Sept-Oct 2008 and prior months, because banks would have been withholding loans much earlier than Sept 2008.

Summary of My Work on the Financial Crisis

Currently available papers and articles are:

• A Depressing Scenario: Mortgage Debt Becomes Unemployment Insurance (NBER wp, 11/19/08)
  
  
• Is the Treasury Impotent? (Economists’ Voice, 11/12/08)
  
  
• Market Responses to the Panic of 2008 (NBER wp with Luke Threinen, 10/23/08)
  
  
• An Economy You Can Bank On. (New York Times 10/10/08)
  
  
• Shorter blog entries on http://www.panic2008.net/
  

Based on these analyses, I have made a number of predictions including, but not limited to:

Banking Sector


• Treasury purchases of banks’ preferred equity will crowd out private capital, for example, by facilitating acquisitions of one bank by another
  
  
• Funds will be available for starting new investment projects – if not from banks, from other institutions. Whether people want to borrow is another story
  
  
• Banks will begin to forgive collateralized loans. The amount of forgiveness will decline with borrower income.
  
  Residential Sector
  
  
• Housing prices will continue to fall after the summer of 2008, by 10s of percentage points
  
  Nonresidential Nonfinancial Business
  
  
• Nonresidential investment goods are cheap, and this increases nonresidential investment, especially in structures
  
  
• Cheap investment goods = cheap stock market
  
  
• U.S. GDP will not fall below $11 trillion (chained 2000 $)
  
  Labor Market
  
  
• U.S. employment will not fall below 134 million.
  
  
• Baby boomers will delay retirement
  
  
• Loan forgiveness programs, such as the FDIC's Loan Modification Program, will dramatically reduce the incentive of affected borrowers to earn income
  
  
  

Auto Industry Revival Recipe

1. pass, and enforce, a right to work law for the state of Michigan
2. bankruptcy for GM that frees the next owner of GM assets from union contract and retiree obligations
3. lobby federal government to bailout pensions and health care of former GM employees
   

Many before me have already explained how the Big 3 do not have the right products, and charge too much for the products they have. Falling gas prices should help the product line problem -- when it comes to large passenger vehicles, the Big 3 have good products.

(1) and (2) will permanently lower productions costs by about 10 percent. Permanently lower costs mean permanently lower prices for consumers. Consumers will by more and auto workers will work more, especially in the short run as the stock of American vehicles equilibrates to a higher ratio with foreign vehicles.

In summary, union related costs have depressed the american auto industry employment for years. The sooner those costs can be eliminated or passed on to taxpayers, the sooner will be the American auto industry revival. If you make quality parts for GM, a GM bankruptcy is the best thing that can happen to revive your business. A GM bailout, on the other hand, will prolong this period of languid American auto production and only delay the revival of GM products -- and thereby your products -- in the marketplace.

National Income Release Likely shows High MPK

Part of BEA's update today of 2008 Q3 GDP is a first release of 2008 Q3 National Income. It includes corporate profits, which permit me to calculate a marginal product of capital for the corporate nonresidential sector. Corporate profits declined less than 1%. Capital income more broadly decline less than 1%.

Before this release, my best guess was capital income was "down about 0.6%" Q2 to Q3.

I am still making a final calculation of the Q3 marginal product of capital, but a 1% capital income decline is trivial; in order for the marginal product of capital to decline from its recent highs to more normal levels, capital income would have to fall 10s of percentage points.

This is quite different from the 1930s: the marginal product of capital was already quite low when the major bank panics hit. Today corporate profits are $1.5 trillion dollars per year and capital income more than $3 trillion per year. That's enough to pay for a lot of investment without banks' help.

My Take on Q3 Revisions

I was pleased with the first release of 2008Q3 GDP, because it confirmed my prediction that real nonresidential investment was continuing to grow. The BEA has tweaked their numbers; those tweaks have not made any perceptible change in nonresidential structures investment. Thus I can continue to gloat about my prediction success at least until January when Q4 numbers are released!

Here is a repeat of my favorite graph showing how nonresidential structures investment continues to rise.

Flashback: How Far Will Housing Prices Fall?

Do you remember this entry from 7 weeks ago? I said that housing prices had 27% more to fall. Last month, Luke and I wrote "...as of July 2008 housing prices more to fall in order to reach the real value they had for several years prior to the boom" and that the fall would be about 30% relative to the PPI.

Today the Case-Shiller index for September 2008 was released, and its value fell 3% from the previous month and 25% from the prior year.

Chicago housing prices have fallen much less over the past couple of months: the Case-Shiller Chicago index has fallen only 2.7% over the last 6 months. Slow rates of Chicago decline are expected because Chicago prices were closer to construction costs, although the rates are so slow that it makes me wonder whether Chicago will ever get back to 1999 levels of (housing price)/(construction cost).

Flashback: The Rhetorical Gap far Exceeds the Policy Gap

Before the election I blogged a couple of times (here and here) about how Democrats and Republicans talk so differently about public policy, but ultimately execute so similarly. My opinion on that matter never pleases anyone, and this election season was no different. Prior to Nov 5, Obama supporters insisted that "any idiot" ought to realize that a President Obama would bring fairness to the tax code, while a President McCain would cut taxes for the rich. At the same time, McCain supporters sternly warned me how commerce would be destroyed by a President Obama's tax-and-spend socialism.

I stuck to my guns and said that Obama exaggerates how much he'd change the tax code and McCain exaggerates how much he'd cut spending; my best guess is that they'd both do essentially the same thing. The main differences between the two, I said, would be with the kind of rhetoric used to serve up a single flavor of public policy, and the excuses rendered for not living up to the partisan promises. [although beside the point, I also opined that Obama's rhetoric would be more inspiring]

Well, the election and Obama's memorable victory was only three weeks ago. Inauguration hasn't even happened yet. Yet talk about tax code fairness ceased even before the Chicago Park District could sweep up the Obama-celebration debris on Nov 5. Today even the Obama team itself admits that it will stick with the tax code they inherit from Bush:

Barack Obama promised to repeal President George W. Bush's tax cuts for the wealthy ahead of their scheduled expiration in 2011. It was part of how Obama would pay for an overall net tax cut aimed at low- and middle-income taxpayers, and an effort to bring what he called "fairness" to the tax system.

No one is talking tax hikes now. Over the weekend, Obama said he has charged his new economic team with devising a plan that would create or preserve 2.5 million jobs over two years. He said the plan would include broad spending plans as well as the middle- and low-income tax cuts he described during the campaign. Aides later said the plan would not include any of the tax increases Obama, as a candidate, had said he would impose on taxpayers who make more than $250,000. Asked Monday when those hikes might go into effect, Obama said, "Whether that's done through repeal, or whether that's done because the Bush tax cuts are not renewed, is something that my economic team will be providing me a recommendation on." (read the full article by JIM KUHNHENN)

This is an inspiring way of saying "I kind of do things that Republicans would, and they would have done things kind of like I will." And that's good news for the economy.

Public Policy is Destroying Employment

The U.S. Treasury is now creating a massive Unemployment Insurance program: off the books, and without Congressional approval. As we know from decades of observing our friends in Europe, Unemployment Insurance raises the unemployment rate.

Specifically, the U.S. Treasury is spending $20 billion on Citigroup preferred stock. As part of the conditions:

"Importantly, the agreement calls on Citigroup to take steps to help distressed homeowners. Specifically, Citigroup will modify mortgages to help people avoid foreclosure along the lines of an FDIC plan that was put into effect at IndyMac Bank, a major failed savings and loan based in Pasadena, Calif. Under the IndyMac plan, struggling home borrowers pay interest rates of about three percent for five years. Rates are reduced so that borrowers aren't paying more than 38 percent of their pretax income on housing."

In other words, the Treasury mandates that Citigroup forgive homeowners in proportion to their lack of income. As I explained in my latest NBER working paper, this kind of forgiveness is already in banks' private interest, but it is not in the public interest. The Treasury is now reinforcing that socially-counterproductive bank policy.

I have worried about this privately for three weeks now. Last week I warned about this on my blog and in the NBER working paper. All other economists have been completely silent on this matter.

Goldman: Acceptable Forecast, Warped Perspective

Goldman Sachs has revised its economic growth forecast. It has been characterized as gloomy, and putting the blame on bad public policy. But let's dissect it.

WARPED PERSPECTIVE

At quarterly rates, GDP growth, they say, will fall 5/4%, 3/4%, and 1/4% from 2008Q3-Q4, 2008Q4-2009Q1, and 2009Q2. That's a cumulative decline of 2.3% 2008Q3 - 2009Q2, or $200 billion, or about $700 per person.

Yes, I typed that correctly. Measured in 2008 dollars, GDP is $14.4 trillion per year, or $3.61 trillion per quarter. Based on the annual percentage rates they publicized, we know that Goldman is predicting $3.56 trillion for 2008Q4, $3.54 trillion for 2009Q1 and $3.53 trillion for 2009Q2 (there may be a bit of rounding error here). The cumulative difference between that forecast and zero growth is merely $200 billion, or about $700 per person.

I am considered to be the optimistic one, but even I explained last month that GDP could fall more than this in the short term. Our economy can recover quickly from an event like that. The 1930s were entirely different: GDP fell a lot more and the recovery was terribly long. But apparently Goldman and others think that today it is worth spending trillions of taxpayer dollars (thousands of dollars per person) merely to avoid the economy's losing $700 per person.

SELF-SERVING

It is a known fact that Goldman Sachs is an investment bank, with a large number of its employees working on Wall Street. It's a known fact that, over the past few months, Wall Street's experience has been far more unpleasant than most other places in America. So it's no surprise that Goldman Sachs would be the gloomy ones, and have a perspective that is not America's.

What's more disturbing is that Goldman is both feeding at the Treasury trough and has been successful at promoting an exaggerated state of alarm.

UI-Steriods: 1,000,000 doses

It's more widespread that I thought: creditors who, in the form of extra forgiveness, reward borrowers for having low incomes. cnnmoney.com wrote yesterday:

"[Freddie and Fannie's] Streamlined Modification Program, set to launch Dec. 15, enables delinquent borrowers to get a modified mortgage that lowers payments to no more than 38% of their gross incomes. ...Several major servicers -- including Bank of America, JPMorgan Chase and Citigroup -- have recently announced expansions of their foreclosure prevention efforts, which could aid nearly a million more borrowers."

Some of these one million borrowers are dual earner households, so let's call it 1.4 million = one percent of the U.S. workforce whose incomes are going to be examined. If we take the 108% year-long forgiveness-based marginal tax rate I calculated earlier, plus a 40% tax rate on federal, social security, and state income tax, we have one percent of workforce subject to almost 150% marginal tax rates for a year. That's not pretty, but still not so widespread to reduce employment as it was in the 1930s.

But how many other people are anticipating that they will ultimately be plugged into a forgiveness formula like that?!

With banks running their own UI programs, Bush's federal extension of UI isn't helping.

The Tax Economics of the Auto Industry

It is estimated that U.S. automakers spend about $1600 per car on so-called legacy costs (health benefits for retirees) and another $800 per car on other union-related added costs, although some of the latter have been cut a bit due to recent negotiations with the UAW. This amounts to an implicit to a $2400-per-car implicit "tax" on American automobile sales that is not levied on the sales of foreign cars.

For the purposes of this essay, I follow the traditional (and likely dubious) assumption in tax economics that retiree benefits cannot be cut. It follows that automaker bankruptcy may free the auto consumer from paying for those retiree benefits, but only by shifting the burden to taxpayers and previous (stock and bond) investors in the U.S. auto industry. In the worst case scenario, taxpayers foot the entire bill, even for the $800-per-car in union related added costs.

Even if taxpayers make up for all of the revenue that would have been obtained by the implicit $2400 per car tax, taxpayers will be better off than they would be if U.S. automakers continue to operate under current union contracts because they are also auto consumers. This is a result known as "Ramsey's Optimal Tax Formula" -- if we must have revenue to pay off a politically favored group, it is better to finance the payoff with a broad-based tax (such as the federal income or payroll tax) than with a narrow tax such as an implicit tax on American auto sales. In this case, the benefits of taxpayer finance (rather than auto consumer finance) are quite large.

In theory, there is a caveat to this result. If the U.S. government had already been following the optimal tax formula, it would have taxed the auto industry more lightly in recognition of the UAW's implicit tax. In this case, changing the UAW's implicit tax into an explicit tax has no effect on the taxpayer-consumer.

Either way, given that the taxpayer is also an auto consumer, he cannot be worse off by letting car companies go bankrupt even though he recognizes that he will foot some or all of the bill for autoworker benefits.

UI on Steroids

Suppose that you bought a house in 2005, and took out a mortgage equal to four year's income. Now your house is worth three year's income.

More bad news: you lost your job, and your income is cut in half because unemployment insurance (UI) only replaces that much.

Your best course of action may be to FAIL to find a new job. First of all, you can continue UI as long as Congress extends it and you are still without a job. More important, Citi-group is your mortgage lender, and (hypothetically) they are especially willing to renegotiate mortgages with people who are unemployed. That is, by remaining unemployed you greatly enhance your chances of seeing one year's salary (on your previous job) taken off your mortgage.

I don't know how common is this situation. I do know that at least some mortgage lenders are considering employment status when restructuring a mortgage:

"[Citigroup] recently streamlined its loan modification program to rework delinquent loans. This revamped program uses a simplified formula to figure out an affordable payment as a percentage of the borrower's gross income. It then reduces the monthly payment to that amount by either reducing interest rates on the loan, extending the loan's term or forgiveness of principal." (from Mamundi 2008, emphasis added)

I am not aware of the percentage used by Citigroup, or the frequency over which it measures borrower's gross income for this purpose. For the sake of illustration, suppose that the percentage were 25. An action taken by a borrower to increase his income would increase his payment obligation by 25 percent of the income increment. If an affordable payment were reevaluated monthly, this would amount to a 25 percent marginal tax rate over the life of the loan. If, say, 2009 income were used to calculate an affordable payment for the years 2010-14 and the interest rate were 6 percent per year, then the marginal tax rate would be 108 percent for 2009 (4.3 times the percentage from the formula) and zero thereafter.

It is conceivable that mortgage restructuring could do significant damage to our labor market. Notice that this is an issue of settling past loans, not an issue with making new ones. I explain these results in more detail in a working paper (available from NBER or from www.caseymulligan.net/w14514.pdf). This research is ongoing, so please check back here for updates, corrections, etc.

Also note that I HAVE CHANGED MY MIND about the damage that deflation could do in today's economy -- it could be a lot via this mechanism.
