One of the most cherished propositions in economics is that market competition by and large raises consumer welfare. But whether political competition has similarly virtuous consequences is far less discussed. This paper formulates a model to explain why political competition may enhance...

Despite the large amount of empirical research on monetary policy rules, there is surprisingly little consensus on the nature or even the existence of changes in the conduct of U.S. monetary policy. Three issues appear central to this disagreement: 1) the specific type of changes in the policy...

This paper provides an explanation for the run-up of U.S. inflation in the 1960s and 1970s and the sharp disinflation in the early 1980s, which standard macroeconomic models have difficulties in addressing. I present a model in which rational policymakers learn about the behavior of the economy...

Inflation equals the product of two terms: an extensive margin (the fraction of items with price changes) and an intensive margin (the average size of those price changes). The variance of inflation over time can be decomposed into contributions from each margin. The extensive margin figures...

What are the economic consequences to U.S. natives of the growing diversity of American cities? Is their productivity or utility affected by cultural diversity as measured by diversity of countries of birth of U.S. residents? We document in this paper a very robust correlation: US-born citizens...

This paper examines the shift in childbirth from home to hospital that occurred in the United States in the early twentieth century. Using a panel of city-level data over the period 1927-1940, we examine the shift of childbirth from home to hospital and analyze the impact of medical care on...

Has U.S. health care for the elderly become more equitable during the past several decades? When inequality is measured by Medicare expenditures, the answer is yes. During 1987-2001, low income households experienced an increase of 78 percent ($2624) in per capita expenditures, double the...

Our answer: not so well. We reach that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the...

This paper presents new estimates of the average tariff on total and dutiable U.S. imports from 1790 to 1820. These previously unavailable series are comparable to the tariff figures available from 1821 in the Historical Statistics of the United States. These early tariffs were much lower, on...

Many economists and educators of diverse political beliefs favor public support for education on the premise that a more educated electorate enhances the quality of democracy. While some earlier studies document an association between schooling and citizenship, little attempt has been made to...
