We provide a new model that generates persistent performance differences amongst seemingly similar enterprises. Our model provides a mechanism whereby efficient incumbent rivals can give permission for an inefficient firm to exist in the presence of efficient entrants. We demonstrate that, in a...

The one-shot nature of most theoretical models of strategic investment, especially those based on asymmetric information, limits our ability to test whether they can fit the data. We develop a dynamic version of the classic Milgrom and Roberts (1982) model of limit pricing, where a monopolist...

This paper develops a dynamic model of retail competition and uses it to study the impact of the expansion of a new national competitor on the structure of urban markets. In order to accommodate substantial heterogeneity (both observed and unobserved) across agents and markets, the paper first...

"We identify a new set of stylized facts on the 2008-2009 trade collapse that we hope can be used to shed light on the importance of demand and supply-side factors in explaining the fall in trade. In particular, we decompose the fall in international trade into product entry and exit, price...

We study the dynamics of price indices for major U.S. cities using panel econometric methods and find that relative price levels among cities mean revert at an exceptionally slow rate. In a panel of 19 cities from 1918 to 1995, we estimate the half-life of convergence to be approximately nine...

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show that monetary targeting would be quite inefficient, with both higher inflation and output variability. This is...

Solar power is now economically competitive with fossil fuels in many countries, yet relatively few homeowners have installed solar panels on their property. A principal reason for this behavior stems from cognitive biases--such as myopia, inertia and herding--that cause consumers to avoid...

This paper, prepared for the annual meetings of the American Economic Association, discusses how the increases in the U.S. budget deficits since 1980 have affected the economies of Western Europe. The analysis emphasizes that U.S. deficits have not only affected these economies directly but have...

Casual observation indicates that in recent years real interest rates in the United States appear to have risen sharply and have remained high relative to historical standards. Many observers have claimed that these high real rates have been transmitted abroad and have lead to high real rates in...

During the decade since 1973, the U.S. economy has become increasingly interdependent with the newly industrializing countries (NICs) among the developing countries. These countries have had high investment ratios to GNP, financed mainly by domestic saving, but also partly by foreign borrowing....
