Two Interesting Articles

Two interesting articles in today's Wall Street Journal include one on how states are able to use federal money allocated for coal mine cleanup to other uses, such as refurbishing the University of Wyoming's football stadium. It appears most of the clean up of old mines was accomplished many years ago but the money continues to come. This is one reason why cutting federal spending turns out to be so difficult.
The second article is more fun--about Doener Kebabs. I look forward to eating these when I go to Germany to teach a short course for a college there. Turkish immigrants brought the food with them to Germany when they came as guest workers in the 1950s. Es schmeckt!

Mankiw on Taxes and Spending

Mankiw's column in yesterday's New York Times is worth a read. He discusses tax and spending policies, noting how a tax credit is often like a spending increase. He argues, as do most economists, that the tax rate should be lowered and the base extended. The latter is done, at least in part, by removing many credits and deductions.

The Stimulus One Year Later According to Robert Barro

Robert Barro has an op-ed piece in today's Wall Street Journal. In it he opines on the effectiveness of the stimulus package, based on estimates of the government spending multiplier he has estimated. His estimates are less than unity, which means that an extra $900 billion of government spending leads to an increase in GDP of less than $900 billion. This differs from the claims made by others such as Paul Krugman, who believes the stimulus was vital but too small. I am unaware of any economic research Krugman has done on the spending multiplier, but he presumes that when there is slack in the economy, such as in a recession, the "crowding-out effects" that might occur in normal times will not take place.

But Krugman's arguments are based on the Keynesian model, which was rejected by much of the profession because of empirical evidence. It also is based on an over-arching concern on the short run. But, it was an emphasis on the short run, as exemplified by government, business, banks, and households, that helped create the problems we currently have. We may yet develop the situation that Keynesians believed after World War II--the economy was inherently unstable and persistent efforts by the federal government would be needed to maintain growth. If so, I believe a key reason for it will be government policies that focused so much on the short run that market forces were not permitted to provide a sustainable growth rate.

Tax Cuts versus Government Spending

Greg Mankiw's column in today's business section of the New York Times compares economic research on the stimulative impact of tax cuts relative to government spending. He cites research papers that find a larger impact for tax cuts, including work done by the President's advisor, Christina Romer. I know space is limited in a column, but I wish Mankiw had emphasized more the difference between temporary changes and permanent changes. As anyone who has had any microeconomics knows (or at least learned at one time) all elasticities are greater the longer the time period.

The stimulus offered while George W. Bush was still president was a tax cut, but a temporary tax cut. The effect was that most people used the tax cut to pay down debt or increase savings. I think these are good things, but they do not stimulate the economy. Similarly, increased spending that is know to be temporary in nature will not have as much effect as an increase in spending that should last a long time. If a firm wants to take advantage of a temporary increase in spending, it will not make long-term investments as part of the process. If the firm believed the spending might be available for many years, it would respond in a different manner. One of the reasons tax cuts provide more stimulus when the cuts are expected to be permanent, or as permanent as anything can be that involves the government, then there is both a spending effect and an incentive effect. The latter is not in place for temporary tax cuts or rebates. Probably the worst think Keynes ever said was, "In the long run, we are all dead." But time passes and constant focus on the short run leads to ad hoc measures that lead to more measures later on.
