What Does Anti-Keynesian Mean?

In the latest edition of his excellent series of podcast interviews, Russ Roberts asked me toward the end what I thought about being characterized as anti-Keynesian as I was in this Economist post The rise of the anti-Keynesians. In a follow-up to the Economist article, David Altig, with basic agreement from Paul Krugman, argued that it was a misnomer because I developed and used macro models (now commonly called New Keynesian) with price and wage rigidities in which the government purchases multiplier is positive (though usually less than one), or because the Taylor rule includes real variables in addition to the inflation rate. In my view, rigidities exist in the real world and to describe accurately how the world works you need to incorporate such rigidities in your models, which of course Keynes emphasized. But you also need to include forward-looking expectations, incentives, and growth effects—which Keynes usually ignored.

In my view the essence of the Keynesian approach to macro policy is the use by government officials of discretionary countercyclical actions and interventions to prevent or mitigate recessions or to speed up recoveries. Since I have long been critical of the use of discretionary policy in this way, I think the Economist is correct so say that I am anti-Keynesian in this sense of the word. Indeed, the models that I have built support the use of policy rules, such as the Taylor rule for monetary policy or the automatic stabilizers for fiscal policy, which are the polar opposite of Keynesian discretion. As a practical prescription for improving the economy, the empirical evidence is clear in my view that discretionary Keynesian policy does not work and the experience of the past three years confirms this view.

Milton Friedman wrote a wonderful review essay on Keynes’ influence on economics and politics which touches on these issues and is still well worth reading. Friedman distinguished between Keynes’ political bequest—the advocacy of discretionary actions taken by powerful government officials—and his economic bequest—the emphasis on aggregate demand as a source of business cycle fluctuations. In the last section of the essay Friedman argues—quoting extensively from Keynes’ famous letter to Hayek on the Road to Serfdom—that the political bequest was very harmful while the economic bequest has many important insights. For simlar reasons using rational expectations models with rigidities or advocating policy rules which react to real economic variables is not inconsistent with an anti-Keynesian or rules-based approach to policy in practice.

A Way Out Of the Budget Impasse

In a column posted today on Bloomberg Views I suggested a way to resolve the budget impasse. It starts with the fact that about $6 trillion in deficit reduction is needed over 10 years to get to balanced budget.The proposal is that the President and the Congress  agree now to $2.5 trillion spending growth reductions and increase the debt limit by the same amount. The question about how to close the remaining $3.5 trillion gap–tax increases or more spending reductions–is then left to debate next year as part of the 2012 election.

This chart–which I have used before–shows the feasibility of the idea. In a speech on April 13 President Obama already suggested about $2 trillion in spending growth reductions. So we are almost there.

A Tale of Two Labor Markets: Today and ’83-’84

Today’s jobs report provides yet more evidence that this is a recovery in name only. The 9.2 percent unemployment rate is certainly a serious problem, but you can understand the problem a little better by looking at the percentage of working-age Americans who are actually working. This percentage declined again to 58.2 percent in June, and is well below what it was when the recovery officially began.

The chart below shows the change–during the 24 months of this so-called recovery–in the percentage of people working and compares it with the recovery after the most recent deep recession of 1981-82. You can see the general recent decline. In contrast the percentage of people working rose sharply in 1983-84. So this time there really has been no recovery in the labor market.

The chart also tells you what might have been. For example, if the employment to population ratio had increased (rather than decreased) in the past 24 months by as much as it did in the 24 months following the 1981-82 recession, then 8.9 million more Americans would have jobs than actually have jobs.

Yesterday the House Budget Committee released a report on the jobs problem and, while mentioning several explanations, argued it is due to an economic policy problem, including the increase in the debt and deficit caused in part by the stimulus packages and spending boom of the past few years. My Bloomberg News column of yesterday shows that the Keynesian revival, which has its ten-year anniversary this month, hasn’t helped.

Time To Renew the Principles of 1776

What’s the best way forward for American economic policy? On Independence Day it’s natural to look to the country’s founding principles—political freedom and economic freedom—for an answer. 1776 was not only the year when Thomas Jefferson wrote the Declaration of Independence, it was the year when Adam Smith wrote the Wealth of Nations. We can learn what to do by studying the alternating periods in American history when careful attention was paid to these principles and when they were recklessly neglected.

From the perspective of today’s dismal economic performance—high unemployment and a nearly non-existent recovery from a devastating recession—the final two decades of the 20th century are particularly relevant for they stand out as unusually good economic times. With lessons learned from the 20th century’s tougher decades, including the Great Depression of the ‘30s and the Great Inflation of the ‘70s, America entered a period of unprecedented economic stability and growth in the ‘80s and ‘90s. Not only were 47 million jobs created, economic growth was more stable than ever before in American history.

Economic policy in the ‘80s and ‘90s was less interventionist in comparison with earlier 20th century decades. Attention was paid to the principles of economic and political freedom: limited government, incentives, private markets, and a predictable rule of law. Monetary policy focused on price stability. Tax reform reduced marginal tax rates. Regulatory reform encouraged competition and innovation. Welfare reform devolved decisions to the states. With strong economic growth and control of government spending the budget moved into balance. As the 21st century began many hoped that applying these same principles to education and health care would create greater opportunities and better lives for all Americans.

But economic policy went in a different direction. Some public officials found the limited government approach to be a disadvantage; they wanted to do more—whether to tame further the business cycle or increase homeownership. Others took the good economic performance for granted, forgetting that good economic policies made that performance possible. Still others forgot the earlier lessons that interventionist policies frequently made things worse. Complacent about the success in the ‘80s and ‘90s, they let down their guard against political pressures that thwart good policy and lead to reckless ones.

So policy moved in a more interventionist direction. The result was not the intended improvement, but rather an epidemic of unintended consequences–a financial crisis, a great recession, and the high unemployment and wasted resources we see now. The change in direction did not occur overnight. We saw increased federal intervention in the housing market in the late 1990s. We saw a countercyclical fiscal policy in the form of rebate checks in 2001, and then a failure to control of government spending growth from entitlements to defense. We saw monetary policy moving in a more activist direction in 2003-2005, and interventionism reached a new peak with the bailouts before and after the panic in 2008. In the past three years Washington doubled down on the interventionist approach, and deficits and debt have exploded. With high unemployment and fears of a secular American decline, there is now an urgent need to get back to the principles of political and economic freedom put forth in the Declaration of Independence and in the Weath of Nations. The good news is that it’s not too late.

No, A Bigger Stimulus Would Not Have Worked Either

Paul Krugman writes (citing Noah Smith) that he agrees with the empirical findings in my critique of the revival of Keynesian activism in the 2000s (the stimulus packages of 2001, 2008 and 2009). In particular, he writes that “it’s far from clear that the ARRA actually led to much of a rise in government spending, while the tax cuts that made up much of the stimulus were probably largely saved.”

But he then goes on to say that the stimulus was too small. That’s not what I found in my paper. As I stated in the paper, my “results do not lend support to” the view “that the stimulus was too small.” Rather the paper showed that “a larger stimulus package—with the proportions going to state and local grants, federal purchases, and transfers to individual the same as in ARRA—would show little change in government purchases or consumption.”

Now, I know that Krugman is trying to distinguish between good and bad Keynesian stimulus packages, and that he would like a stimulus package with higher proportions going to federal, state, and local government purchases than the 2009 stimulus, or, for that matter, the 2008 stimulus or the 2001 stimulus. But experiences from the 1970s raise serious doubts about the political and operational feasibility of such discretionary fiscal policy. So do recent experiences in many other countries, as shown by Hyun Seung Oh and Ricardo Reis.

In a simple Keynesian model, all the government has to do to combat a recession is quickly increase government purchases, but the difficulty with doing so in practice is one of the classic arguments against discretionary fiscal policy. Of course, it is not the only argument. Small or unreliable multipliers, the legacy of increased debt, the unpredictability and temporariness of such policies are some of the other arguments. Using dynamic models with expectations and incentives, I have found very small multipliers (around .5)

For these reasons I argued in the November 2008 article which Krugman cites that a better fiscal policy would be to rely on the automatic stabilizers and enact more permanent reductions in tax rates (or at least pledge not to increase tax rates in a recession).

As early as the summer of 2009 it was clear that ARRA was not working as intended, as John Cogan, Volker Wieland and I reported. Research since then has uncovered the reasons why. One reason is that very large stimulus grants to the states did not go to infrastructure spending as intended, and that’s what Ned Gramlich found out about Keynesian stimulus packages thirty years ago.

How to Resolve the Stimulus Debate: Use Data Not the Same Models Over Again

  • Predictions made in early 2009 about whether the stimulus package would work varied widely because the models used to make the predictions varied widely. Models used by Christy Romer and Jared Bernstein predicted large effects of the 2009 stimulus (ARRA), while models used by John Cogan, Tobias Cwik, Volker Wieland and me predicted small effects.
  • Now that ARRA is winding down people are asking which prediction was right. Did ARRA stimulate the economy significantly or not? To answer this question the same models are again being used, but now to evaluate the policy. CBO, for example, takes this approach in their congressionally mandated impact studies of ARRA.
  • But you learn virtually nothing about whether a stimulus package worked using this approach because the models simply repeat the same prediction story over again.
  • Unfortunately, the complexity of models with a hundred or more equations makes it difficult to see this point, so I created an illustration with stylized one-equation models which people seem to like. A little algebra is needed.
  • Consider two models relating the size of the stimulus package (symbolized by S) to GDP (symbolized by Y). Model A is Y= αS + Z and Model B is Y = Z, where Z is an unobservable shock and α is a coefficient which we set to 1.5.
  • Suppose that a stimulus is enacted with S = 2, but Y falls to -1. Then the shock implied by Model A is Z = – 4 while the shock implied by model B is Z= -1.
  • Now consider policy evaluation of the stimulus based on a counterfactual where there is no stimulus so S=0.
  • Economists using Model A would say:
    Just as we predicted, the stimulus package worked. Without it, Y would have fallen to -4 rather than -1. The decline in output would have been 4 times as deep, a Great Depression 2.0.
  • Economists using Model B would simply say:
    Just as we predicted the stimulus package didn’t work.
  • The best way to way to deal with this problem is to look empirically at the direct effect of the stimulus using actual data, but without imposing a specific model structure like Model A or Model B. In a paper forthcoming in the Journal of Economic Literature I use this direct approach and find that the ARRA did not stimulate the economy.

Unchanged Debt Explosion

CBO’s Long-Term Budget Outlook released this week is essentially the same as last year’s: without a change in policy the debt will explode to over 900 percent of GDP. One difference is that CBO decided not to print out the debt ratio in their spread sheet “Data Underlying Scenarios and Figures” as in the past two year once the ratio went beyond 200 percent. So in the following graph I computed the ratio from the revenues and spending projections. This means that the backdrop used two years ago by the “best Economics 1 lecturer ever” still applies, though the quest lecturer is now 2 years old and we still haven’t fixed the problem.

This is why it is so important to adopt reforms like the ones proposed this week by Congressman Kevin Brady, which would hold down federal spending as a share of GDP and stop the debt explosion. By using potential GDP rather than actual GDP his proposal would eliminate the pro-cyclical spending implied by many other spending cap proposals (which use actual GDP) where federal spending would rise rapidly during booms and fall rapidly during recessions.

Today I touched on the importance of getting spending ratios down and returning to sound fiscal (and monetary) policy in this “Big Interview‘ with Kelly Evans at the Wall Street Journal

The Two Year Anniversary of the Non-Recovery

This month marks the two-year anniversary of the end of recession and start of recovery. But it’s a recovery in name only, so weak as to be nonexistent. And it has been weak from the start. Real GDP growth has averaged only 2.8 percent per year compared with 7 percent after last deep recession in 1981-82, as shown in the following chart. And the unemployment rate is still over 9 percent.
Today the Joint Economic Committee of the Congress held a hearing on whether a credible plan to reduce government spending growth would bolster or hinder the recovery. I argued that a credible budget strategy would strengthen the recovery, by removing the threats of another fiscal crisis, higher taxes, higher inflation and higher interest rates—all caused by the huge deficits and growing debt and all impediments to private investment and job creation (written testimony here and opening remarks at C-Span 6:23 minutes here). To balance the budget without increasing taxes the plan would have to reduce spending growth by $6 trillion over ten years.

Fortunately, there are some signs of progress: The election last November sent a message to Washington to reduce the deficit and the debt; the 2011 budget deal reduced 2010-2011 growth in discretionary budget authority from +$39B to -$39B; President Obama withdrew his first budget proposal for 2012 and is agreeing to less spending; and the idea of tying the debt limit hike to reductions in spending growth is holding, despite protests from the Treasury Secretary and the Fed Chairman.

One way to implement a credible budget strategy in our current divided government would be to agree now to reduce spending by $2.5 trillion over ten years (including material changes in 2012) as part of the $2.5 trillion debt limit hike, and then debate how to deal with the remaining $3.5 trillion gap in the presidential election. One side would say to close the gap by raising taxes. The other side would say to close the gap by reducing spending. While the outcome would still be uncertain, there would be far less uncertainty about the budget than currently exists.

Why Avoiding Bailouts is Good Policy

Asgeir Jonsson’s interesting and perceptive article in today’s Wall Street Journal provides a clear lesson for students and policymakers alike about the harm that comes from bailouts and the good that comes from avoiding them. If a government recognizes the reality of a solvency problem early, and deals with it, its citizens will end up much better off than if it wishfully thinks it’s a liquidity problem and takes bailouts. Iceland recognized its problem early and took action, while Ireland thought wishfully and took bailouts, and that’s made all the difference.

It was a lesson learned by many emerging market countries about a decade ago, and it has made a big difference for them too. That’s one reason why an emerging market leader would make a good IMF leader today. More on that later.

Why Not Go For 5% Growth?

Some skeptics have complained about the 5% national economic growth target put forth by former Minnesota Governor Tim Pawlenty in his speech this week about his economic plan. They say it can’t be done. But I think the goal makes a great deal of sense. It would focus policymakers like a laser beam on the great benefits that come from higher growth and on the pro-growth policies needed to achieve it. As with any goal, if you take it seriously, you’ll choose policies that work toward that goal and reject those that don’t.

As stated in the speech, “5% growth is not some pie-in-the-sky number.” One way to see why is by dissecting the number into its two parts using basic economics. As we teach in Economics 1, economic growth equals employment growth plus productivity growth. Productivity is the amount of goods and services that workers produce on average in a given period of time. Thus, higher economic growth can come from higher employment growth or from higher productivity growth. Now consider some examples of average growth rates over the next ten years.

First, look at employment growth. Given the dismal jobs situation, that’s the highest priority. Currently the percentage of the working-age population (age 16 and over) that is actually working is very low at 58.4 percent. In the year 2000 it reached 64.7 percent, so that is at least a feasible number. Raising the employment-to-population ratio to 64.7 means an employment increase of 10.8 percent (64.7-58.4/58.4 = .108) or about 1 percent per year over 10 years, even without any growth of the population. Adding in about 1 percent for population growth (from Census projections), gives employment growth of 2 percent per year.

Now consider productivity growth. Since the productivity resurgence began around 1996, productivity growth in the United States has averaged 2.7 percent according to the Bureau of Labor Statistics. So numbers in that range are not pie in the sky. As Harvard economist Dale Jorgenson and his colleagues have shown, the IT revolution is part of the explanation for the productivity growth, and, if not stifled, is likely to continue, as is pretty clear to me as I sit a few hundred yards from Facebook and other high-tech firms.

Now if we add the 2.7 percent productivity growth to the 2 percent employment growth, we get 4.7 percent economic growth, which is within reaching distance of—or simply rounds up to—the 5 percent target set by Governor Pawlenty. Thus, five percent growth is a good goal to aspire to, whereas 3 or 4 percent would be too little and 6 or 7 percent too much. Of course, one can fine-tune these calculations–for example, by estimating changes in hours per worker or the difference between nonfarm business (which BLS productivity numbers refer to) and total GDP–or raise questions about demographic effects on the employment-to-population ratio. And one could use different examples, perhaps lower employment growth and higher productivity growth, but the basic point about the goal would be the same.

You can see how the types of pro-growth policies in the Pawlenty plan would work toward the goal by reducing spending growth enough to balance the budget without tax increases and thereby remove threats of a debt crisis; by lowering marginal tax rates to spur hiring and job growth; by scaling back unnecessary new regulations which impede private investment and higher productivity, and by restoring sound monetary policy to remove uncertainty about inflation or another financial crisis.
