We combine a structural model with cross-sectional micro data to identify the causes and consequences of rising concentration in the US economy. Using asset prices and industry data, we estimate realized and anticipated shocks that drive entry and concentration. We validate our approach by...

Many arguments that have been advanced in favor of maintaining capital controls within the EC have not paid sufficient attention to the welfare consequences of this type of market intervention. Our paper provides a simple, optimizing framework in which the welfare consequences of capital...

The paper proposes a new welfare-based measure to evaluate the distributive effects of public programs. The proposed measure differs from traditional approaches in two important ways: first, it is based on life-cycle considerations, since most public expenditure programs have an intertemporal...

In addition to transferring about 16 percent of GDP from exporters to importers, Uzbekistan’s quasi-fiscal multiple exchange rate regime generates identifiable welfare losses of 2-8 percent of GDP on import markets and up to 15 percent on export markets. These excess burdens have increased...

The financial crisis in the advanced countries that began in 2007 has led central bankers to adopt unconventional policy measures as policy interest rates neared the zero bound. One suggestion (Blanchard, Dell’Ariccia, and Mauro, 2010) has been to raise inflation targets to provide more room...

The paper evaluates the impact of HIV/AIDS on welfare in several countries affected by the HIV/AIDS epidemic. Unlike studies focusing on the impact of HIV/AIDS on GDP per capita, we evaluate the impact of increased mortality using estimates of the value of statistical life. Our results...
