Recent empirical research has identified a significant amount of volatility in stock prices that cannot be easily explained by changes in fundamentals; one interpretation is that asset prices respond not only to news but also to irrational "noise trading." We assess the welfare effects and...

This paper examines the changing cyclical variability of economic activity in the United States. It first shows that the decline in variability since World War II cannot be explained by changes in the composition of economic activity or by the avoidance of financial panics. We then show that...

We use the revised estimates of U.S. GNP constructed by Christina Romer (1989) to assess the time-series properties of U.S. output per capita over the past century. We reject at conventional significance levels the null that output is a random walk in favor of the alternative that output is a...

Using data from the United Nations Comparison Project and the Penn World Table, we find that machinery and equipment investment has a strong association with growth: over l9&)?l95 each percent of GDP invested in equipment is associated with an increase in GDP growth of 1/3 a percentage point per...

This paper uses Taylor's model of overlapping contracts to show that increased wage and price flexibility can easily be destabilizing. This result arises because of the Mundell effect. While lower prices increase output, the expectation of falling prices decreases output. Simulations based on...

This note shows that contrary to widespread belief there is little evidence that the business cycle is asymmetric. Using American data for the pre- and post-war periods and data on five other major OECD nations for the post-war period, we are unable to support the hypothesis that contractions...

As measured by the pace of city growth in western Europe from 1000 to 1800. absolutist monarchs stunted the growth of commerce and industry. A region ruled by an absolutist prince saw its total urban population shrink by one hundred thousand people per century relative to a region without...

Closed-end mutual funds provide one of the few cases in which economists can observe quot;fundamentalquot; values directly, and compare them to market values: the fundamental value of a closed-end fund is simply the net asset value of its portfolio. We use the difference between prices and asset...

We use the revised estimates of U.S. GNP constructed by Christina Romer (1989) to assess the time-series properties of U.S. output per capita over the past century. We reject at conventional significance levels the null that output is a random walk in favor of the alternative that output is a...
