Plain Sense Economics

At about the 6th or 7th week of my Principles of Macroeconomics class we have a kind of broad (though not deep) understanding of how the economy works, how we measure it, and some of the things government does to influence it. We’ve learned about fiscal policy and monetary policy; we have a rough idea of what happens when inflation spurts (though most of my students haven’t seen domestic U.S. inflation above 4-5 percent); and we have a visceral and personal understanding of unemployment. We know a recession when we see it.

Now comes the incredibly difficult climb out of the recession trough. We’ve started climbing, with two successive quarters of positive real GDP growth. The newspapers, cable, talk shows, and blogosphere are filled with opinions, warnings, and predictions. I’m in no position to give a complete prescription for future economic policy, but this is an excellent time for students to be thinking through the issues. They need to separate out the fundamental building blocks of a strong economy and push aside alarmist claims.  Here’s a list of things to think about:

1. Monetary policy and the Federal Reserve: In a mild recession the Fed is our policy instrument of choice. They loosen the money supply, which in turn lowers interests rates a bit, which in turn  helps consumers buy goods and businesses to invest in the future. In the recession that started December 2007, the Fed started with this response but the depth and seriousness of the downturn outstripped the ability of routine monetary policy. They then turned to extraordinary steps to provide stability and liquidity in the financial markets, and have worked to maintain a banking system that will receive deposits from trusting depositors and make loans to worthwhile borrowers. To do this they pumped billions (over a trillion) of dollars into our system.They are now focused on how to retrieve that excess money, so that a more active economy doesn’t use it to spur inflation. They’ve been thinking about this a lot, and Chairman Bernanke insists they will be able to gradually reverse the steps they took, without sending the economy in a tailspin. The Fed also has to decide when to reverse the “normal” monetary policy and started pushing interest rates up. As I see it they are working in kind of a LIFO (last in; first out) order. The most serious and unusual interventions will be corrected first, and then the milder interest rate policies will be corrected as the economy approaches a more normal course.
2. Fiscal Policy and the Congress and Administration: Congress correctly passed a large stimulus spending bill over a year ago. The economy  needed it; routine monetary policy was not going to be sufficient to end the recession; and it would have been political suicide not to take action. The stimulus bill was not perfect. It was probably not large enough. It had some favorite son policy objectives that hindered speedy impact of the spending on the economy, and it had some not very effective tax cuts in order to garner bipartisan support.I’ve learned to appreciate a “prime the pump” analogy for fiscal policy actions like this. If you’ve ever had to use a hand pump you know that sometimes you have to add water in the top in order to get the process working. Government stimulus funds are like priming the pump. They immediately add something to the GDP, since government spending is one component of GDP. The real test of a fiscal stimulus is whether the priming works. In an ideal case, the initial injection of spending prompts a cascading series of new spending decisions in the private sector. This is the essence of what my students learn as the multiplier effect. New spending on roads means more wages for road workers, who hopefully become more likely to spend, and the establishments where those workers spend have the same opportunity. There are plenty of signs that the initial stimulus money started improving GDP. Whether that money has successfully primed the pump is an open question. Some policy experts are calling for more stimulus – a second priming. Others (not including those who object on philosophical grounds to more government spending) worry that another fiscal stimulus would boost the economy just as it is getting better on its own, and could spark an inflationary spiral.There has been a flurry of “job bills” discussed by the administration and Congress. Many of these are responses to a perceived (probably real) concern among the American voter that jobs aren’t coming back quickly enough and something needs to be done about it. I don’t know enough about them to comment thoughtfully. Based on past performance it is easy to guess that some proposals will do little to make a permanent shift in the employment picture, and that some will have serious side effects. One quick example – just about any “Buy American” restrictions will hurt our economy in the long run and have minimal benefits in the short run. The Smoot-Hawley act passed in the early years of the recession is our number one example of the problems of drawing up the bridges and protecting our own workers at the expense of other world markets. On the other hand jobs bills that can reduce structural unemployment through retraining, relocation, and other adaptive strategies are money well spent.
3. Federal Deficit and Debt: This is the trickiest balancing act. It also has the most heat and the least amount of light in media discussions. Here’s what the Congressional Budget Office says about the near term situation:

CBO projects, that if current laws and policies remained unchanged, the federal budget would show a deficit of $1.3 trillion for fiscal year 2010. At 9.2 percent of gross domestic product (GDP), that deficit would be slightly smaller than the shortfall of 9.9 percent of GDP ($1.4 trillion) posted in 2009. Last year’s deficit was the largest as a share of GDP since the end of World War II, and the deficit expected for 2010 would be the second largest.

One way to look at this issue is represented by Paul Krugman:

Contrary to what you often hear, the large deficit the federal government is running right now isn’t the result of runaway spending growth. Instead, well more than half of the deficit was caused by the ongoing economic crisis, which has led to a plunge in tax receipts, required federal bailouts of financial institutions, and been met — appropriately — with temporary measures to stimulate growth and support employment.

Gregory Mankiw is less happy about projected deficits:

The troubling feature of Mr. Obama’s budget is that it fails to return the federal government to manageable budget deficits, even as the wars wind down and the economy recovers from the recession. According to the administration’s own numbers, the budget deficit under the president’s proposed policies will never fall below 3.6 percent of G.D.P. By 2020, the end of the planning horizon, it will be 4.2 percent and rising.

My own take? Closer to Krugman than Mankiw, but I worry that a partial economic recovery or some call for fiscal stimulus will produce not-well-thought-out-spending plans. These won’t help much, in terms of recovery, they are likely to be persistent beyond the current economic problems, and they won’t help re-establish a deficit closer to 4-5% of GDP.
