A structural retirement model is estimated using data for tenured, male faculty employed in the 1970's at 26 high quality private colleges and universities. Simulations of raising and then abolishing the mandatory retirement age suggest very large increases in full time work by faculty members...

This paper develops a model of sectoral labor mobility and tests its main implications. The model nests two distinct hypotheses on the origin of mobility: (a) sectoral shocks (Lucas and Prescott, 1974) and (b) worker-employer mismatch (Jovanovic, 1979, Miller, 1984, Flinn, 1986). We estimate the...

We show that the effects of tariff changes on welfare and import volume can be fully characterized by their effects on the generalized mean and variance of the tariff distribution. Using these tools, we derive new results for welfare- and market-access-improving tariff changes, which imply two...

The performance of empirical money demand equations over the past decade raises serious questions about money demand predictability. A variety of specifications were presented to explain past episodes of apparent money demand instability, but their success in predicting future money demand is...

In recent years, the study of labor supply has occupied the attention of a large number of economists. With the growth in interest in the topic and with the inevitable diversity of economic models and statistical methods proposed by new entrants in the field, the literature has developed its own...

Models with constant-elasticity of substitution (CES) preferences are commonly employed in the international trade literature because they provide a tractable way to handle product differentiation in general equilibrium. However this tractability comes at the cost of generating a set of...

This paper provides a welfare economic analysis of the problem of districting. In the context of a simple micro-founded model intended to capture the salient features of U.S. politics, it studies how a social planner should allocate citizens of different ideologies across districts to maximize...

Is the long-term trend of the economy -- growth -- substantially influenced by the short-term movements -- business cycles -- and, if so, how? Are business cycles subject to major secular changes? Are these fluctuations the natural way growth takes in private enterprise economies or are they...
