Eurologic


The word has come down from on high in Europe.  Merkozy have decided:

1. Henceforth, after Greece, there will be no more haircuts administered to creditors of sovereign debt.  All obligations will be paid in full, no matter what interest rate has to be paid or how onerous the debt service program has become.

2. Every country will be subjected to hard limits on its budget deficit and must even show progress toward reducing debt-to-GDP to 60% if it is now above that target.

There are problems with each of these taken alone, but has anyone noticed that, under predictable circumstances, they contradict each other?  You can explain this as a quid pro quo for the two main players in the Eurozone, but sometimes political agreements also have to make sense.

A Modest Tactic for Improving Teaching


Yesterday’s lesson plan was fulmination; today’s is incremental improvement.

We—those of us who teach economics and other subjects—use exams and quizzes to evaluate students and assess our own effectiveness at reaching educational goals.  Some questions are narrow and technical, others broad and open-ended.  I want to talk about the narrow ones.

Narrow, close-ended questions are usually written to find out if the student can supply the correct answer.  The information we draw from them is whether the student “gets it” or not.  If not, and if there is enough time for it, we will go back and see if more explanation can facilitate the getting.

I propose the opposite approach: design these questions to see whether students have fallen into certain predictable errors.  If they have, unteach them.  The underlying conception behind this strategy is that the process of learning is not mainly, or at least only, that of gaining mastery over items of skill and knowledge, but also casting off false habits and beliefs.  The mind is not a tabula rasa but a messy blackboard, and if you simply try to overwrite it you will often get more mess at the end.  The critical tool is an eraser.

This is especially a problem in economics.  Students are exposed to a vast amount of information about economic topics outside the classroom, and a lot of it is wrong.  This exposure began long before they had the ability to question it, so false beliefs are often deeply embedded.  Worse, there are powerful interests operating through politics and popular media who benefit from particular misconceptions and feed them incessantly.  (Think, for instance, about why it is that most students entering their first macroeconomics class believe that inflation, by raising prices, reduces consumers’ real income—unaware that wages are also prices.)

If you want to organize assessment and teaching around error reduction, the key step is empirical.  You have to spend a lot of time listening to your students, not to find out whether they are saying what you want them to say, but simply listening to what they are saying.  What are their actual beliefs?  How do they define for themselves the technical terms you are using in the classroom?  How do they read equations, and how do they go about trying to manipulate them?  Look for errors in clusters, common pathways that lead them away from the goal you are trying to reach.  Then build the narrow questions in your exams and quizzes around what you have found, and use the results to guide your teaching in a more fruitful deconstructive direction.

A Republican Who Doubts the Laffer Curve?

Congressman David Schweikert of Arizona suggests that the payroll tax holiday will increase the deficit:

The simple fact is that this sort of temporary tax stimulus has repeatedly shown that without offsets, they only stimulate bigger federal deficits.


OK – but Republicans also want us to believe that tax cuts for well to Americans pay for themselves. The original Laffer curve was a proposition that even in a full employment economy, tax rate cuts so increase economic activity that tax revenues go up. Laffer described this in terms of reducing the wedge between the demand for labor and the supply of labor, which a reduction in the payroll tax would accomplish.

But to be fair to the Congressman – I should mention two points: (1) few labor economists ever bought the assumption that the labor curve was that elastic; and (2) we are not currently in a full employment economy. Point (2) would have us think in terms of the Keynesian marginal propensities to consume for households receiving the tax cut. If the household were very well to do, one would think the marginal propensity to consume would be low, which would lead to the conclusion that “tax stimulus” would “only stimulate bigger federal deficits”. But tax cuts for the working poor – which is what this payroll tax holiday is designed to accomplish – could lead to an increase in economic activity.

Conclusion – by any economic model, the Congressman has this exactly backwards. But what else is new?

Mankiw’s Reply to the Walk-Out


Whatever my disagreements with Greg Mankiw’s op-ed self-defense today, I appreciate that he takes his dissident students seriously and refrains from slinging labels, pulling rank or other repressive tactics.  Protesters don’t always get this treatment.

That said, I think Mankiw fails to see two ways in which his introductory course, and other mainstream econ courses, impose a worldview that makes thinking constructively about economic problems less rather than more likely.

Occupy Chico State

On Thursday morning while riding to school, the main entrance was blocked with police tape. Supposedly someone had called in a bomb threat. Later during the day, my office building was evacuated because of some kind of mechanical malfunction. Finally, a fire drill set off alarms and forced us to leave the gym. All that seemed like a series of curious coincidences.

That night I was scheduled to give a talk at the Occupied Chico State teach-in, which was supposed to be followed by a take-over of the administration building. Because of the (phony?) bomb threat, the building was locked down early.

I had intended to discuss a sequence of the Bonus March, the GI Bill, which made higher education more accessible, then Reagan's 1966 institution of tuition for the previously tuition-free university system, culminating in the mess we have today. On Friday, I gave a brief overview of the talk on our local NPR station.

Here is our unedited conversation.

Quote of the Day, December 3, 2011


“If you have the 1 percent saying, ‘Tax the 99 percent’ and the 99 percent saying, ‘Tax the 1 percent,’ you have a standstill.”

—Joseph Zarelli, lead Republican budget negotiator in the Washington State Senate, as quoted in the New York Times.

Not the Best News on the Employment Situation

Before we get too giddy over the news that the unemployment rate fell from 9.0% to 8.6%, we should note that the employment to population ratio barely increased from 58.4% to 58.5%. The big news really is that the labor force participation rate fell from 64.2% to 64.0%. Only hacks like Lawrence Kudlow get giddy when the unemployment rate falls because folks are no longer officially in the labor force. Most of us consider the discouraged worker effect bad news.

Also mind you that the rise in the employment to population ratio is due to the reported rise in employment per the household survey which claimed employment rose by 278,000. The payroll survey claimed an increase of only 120,000, which was really disappointing given that ADP said private employment rose by 206,000. Private employment per the payroll survey did rise by 140,000 by government employment fell by 20,000 (4000 drop in Federal employment, 5000 drop in state employment, and 11,000 drop in local government employment). As noted in my previous post the Senate Republicans wants even less government employment. Go figure.

The Balanced Budget Multiplier is Not Negative

Senate Republicans have a condition for supporting the continued payroll tax holiday:

Senate Republican leaders introduced a bill that would keep the payroll tax rate at its current level for another year. The cost is roughly $120 billion. Senate Republicans would offset most of the cost by freezing the pay of federal employees through 2015 and gradually reducing the federal work force by 10 percent.


The marginal propensity to consume for reductions in payroll taxes maybe be high but it is still less than unity. So if we reduce government purchases by the same amount as reduce payroll taxes – this proposal would be contractionary. I guess the good news here is that some of the reduction in government purchases would be deferred.

I guess in a world of PAYGO, however, we should ask how the Democrats propose to offset the loss in payroll taxes revenues:

Senate Democratic leaders want a deeper temporary reduction in Social Security payroll taxes. They would provide payroll tax relief to employers as well as employees. And they would offset the cost with a 3.25 percent surtax on modified adjusted gross income in excess of $1 million.


In other words, raise taxes on households who are not liquidity constrained which means if there is anything left to Barro-Ricardian equivalence, perhaps the marginal propensity to consume for changes in taxes on the very well to do is less than the marginal propensity to consume for reductions in payroll taxes. So if the goal is to increase aggregate demand – then the Senate Republican idea is awful whereas the Senate Democrat idea makes sense.

Morality: The Ecological Inference Problem

One further word on the hazards of assessing the moral position of a country:


The moral culpability of a population is not evenly distributed among its members. This is true in issues of war and peace as well as debt service. If one talks of “punishing” miscreants, as Merkel has done, some attention should be given to whether those being punished are the ones who misbehaved.

Unfortunately, the entire point of the bailout process is to cushion the losses of financial institutions, many of which (and many of whose high-level officers) profited by assuming excessive risk: they got the returns in the boom and now the taxpayers are stuck with the losses in the bust. Moreover, the taxpayers are disproportionately those who did not prosper in the bubble economy; ordinary working people have their taxes withheld from their paychecks and skimmed off through the VAT. The fast-and-loose crowd are shielded by unreported income, legal and illegal tax dodges and the like. True, the line can be fuzzy – low income people pay under the table too – but the balance of the burden does not correspond to the balance of the benefit.

This unfairness is a moral issue. To ignore it à la Merkel is a moral problem.

It reminds me of a saying: When the budget cuts come, we hear that it is the fat that will be cut, not the bone. Unfortunately, it’s the fat that makes the cuts.

Success and Morality in a Market Economy

There has been a lot of talk about economic success and moral virtue recently: the Tyler Cowen encomium to the morality of Teutonic creditors I jumped on yesterday, the Zingales conflation of meritocracy and justice that Andrew Gelman skewers today, and, on the other side, the complaint one sometimes hears from the 99-percenters that we are being dragged down by the greed of the other 1%.  My favorite observation on all this comes from one of the most eminent of Victorians, John Ruskin.  (Incidentally, I first came across this quotation in P. S. Atiyah's magnificent The Rise and Fall of Freedom of Contract.)

In a community regulated by laws of demand and supply, but protected from open violence, the persons who become rich are, generally speaking, industrious, resolute, proud, covetous, prompt, methodical, sensible, unimaginative, insensitive, and ignorant.  The persons who remain poor are the entirely foolish, the entirely wise, the idle, the reckless, the humble, the thoughtful, the dull, the imaginative, the sensitive, the well-informed, the improvident, the irregularly and impulsively wicked, the clumsy knave, the open thief, and the entirely merciful, just, and godly person.

I Hope “The Moral Superiority of the Germans” Isn’t Translated Into German

Merkel et al. hardly need more encouragement. But if they must read this latest howler from Tyler Cowen, let them also bear in mind:


1. The entire premise of the argument is incoherent. On the one hand, TC says he is not comparing the morality of the German people to other Europeans—that would be “false and repugnant”—but rather the “system-wide” virtues of Germany versus those of the peripherals. On the other, he judges the peripherals to be morally inferior because they wish to default on their debt obligations. But the “they” who choose to default are not systems but individuals. So, yes, this is an argument about some people being more moral than others.

2. Saving and borrowing are partly matters of choice, but also matters of circumstance. Consider, for instance, the permanent income hypothesis, which tells us that when your income rises unexpectedly you save more, and when it falls you save less—even though your preferences for saving out of permanent income remain constant. This is where the trade surpluses and deficits come in. Without adhering to any particular model of savings behavior, it is clear that Germans have had more income because of their exports (half of German income is earned in the export sector), and countries with trade deficits have, for this reason, lower incomes. Of course, net savings and the current account are two measures of the same thing.

3. Even worse is the claim that default is simply a matter of choice—that those who propose defaulting on debts are less moral than their creditors. Except for Greece, loans taken out by public and private borrowers were generally in good faith. The economic catastrophe that decimated their finances was unanticipated. You could say they engaged in poor judgment by not taking the risk of such a catastrophe into account, and you would be right, but this verdict applies equally to the lenders. It is simply foolish, for instance, to say that, if interest rates remain at their current level, Italians are “choosing” to default. At 7% they have to pay 8.5% of GDP just to roll over, and the economic shrinkage this implies would raise that share year after year. Yes, Italians have assets, but if they sell them so that the state can tax the sales and redirect the revenues to debt service, then the returns on those assets will no longer accrue to Italians, and we are back, more or less, at the same point.

4. To sum up, the injunction to honor debts is like a lot of other obligations in this world. You should provide for the needs of your children. You should return your books to the library on time. If I lend you my car, you should avoid having it damaged in a collision. If you can do these things you should. If you can’t it depends on the reasons. Throwing poor parents into prison because they don’t give enough support to their children is neither good morality nor good economics. Same with people who get sick, can’t go out, and have overdue library books. Same with someone in a borrowed car who ends up in the middle of a giant crash. If the real estate market crashes in Spain, and the government is forced to step in to prevent a financial meltdown, what is the morality or economic sanity of demanding that the people of Spain be punished and forced to undergo a generation or more of austerity?

Quote of the Day

The Genealogy of Occupation

Much has been written recently on the question of where the Occupy Wall Street movement came from. The assumption seems to be that it represents a new manifestation of the counter-globalization ethos that first showed up in Seattle, 1999.

In some ways this is true, but the actual tactic, camping out, looks to me like an evolution from the tree-sitting strategy of radical environmentalists. Forget about Facebook and Twitter: this is the REI generation, and they want to climb and bivouac their way to liberation. It really makes sense when you think about it. To transgress the landscape of capitalist property rights, you need the proper gear. The only anomaly I can see is that pepper spray is being used against the campers, not by them.

Footnote: It might be argued that the starting point was really Greenpeace, which drew on small craft culture for its maritime adventures. Having noodled around in both outdoor and boat equipment shops, I think I can say that they represent two rather different slices of humanity, and the probability of crossover was slim. Of course, Greenpeace was also practicing urban mountaineering around the same time as Earth First was exploring the canopy zone.

The Problem with Pop Economics, Paul Seabright Edition


Maybe you’re in a hurry, so here is the problem in its general form: most of the reading public, even most of the fairly well-educated reading public, have little exposure to mainstream economic reasoning.  If they ever took an econ course, they did not come away with a durable understanding of opportunity costs, markets as cost-benefit algorithms and coordinating devices, market failure, etc.  This means there’s always an audience for a book that packages these rather standard ideas in a clever, unexpected or cool way.  Unfortunately, underneath the ribbons and shiny paper, it’s the same old same old.

Quote of The Day

I am currently making my way through Hume's History of England - a pure joy - and ran across a quote to share. In his discussion of the 1640 Long Parliament and the execution of Lord Strafford, he has this to say about the Puritan leaders Pym, Hambden and Vane:

Some persons, partial to the patriots of this age, have ventured to put them in a balance with the most illustrious characters of antiquity; and mentioned the names of Pym, Hambden, Vane, as a just parallel to those of Cato, Brutus, Cassius. Profound capacity, indeed, undaunted courage, extensive enterprize; in these particulars, perhaps the Roman do not much surpass the English worthies: But what a difference, when the discourse, conduct, conversation, and private as well as public behaviour, of both are inspected! Compare only one circumstance, and consider its consequences. The leisure of those noble ancients was totally employed in the study of Grecian eloquence and philosophy; in the cultivation of polite letters and civilized society: The whole discourse and language of the moderns were polluted with mysterious jargon, and full of the lowest and most vulgar hypocrisy.
