Why do low-income individuals often oppose redistribution? We hypothesize that an aversion to being in "last place" undercuts support for redistribution, with low-income individuals punishing those slightly below themselves to keep someone "beneath" them. In laboratory experiments, we find...

We document a large increase in the cyclicality of the incomes of high-income households, coinciding with the rise in their share of aggregate income. In the U.S., since top income shares began to rise rapidly in the early 1980s, incomes of those in the top 1 percent of the income distribution...

We measure the impact of individuals' looks on life satisfaction/happiness. Using five data sets, from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow placing lower bounds on the effects of beauty. Beauty raises happiness: A one...

The paper proposes an instrumental variables version of the Huber estimator as an alternative to the IV-Krasker Welsch estimator. The IV-Huber estimator is analytically and computationally much simpler than IV-Krasker Welsch. In the context of an empirical study of the importance of borrowing...

This paper documents the high level of job security protection in Latin American labor markets and analyzes its impact on employment. We show that job security policies have substantial impact on the level and the distribution of employment in Latin America. They reduce employment and promote...

Measurement of seat belt and air bag effectiveness is complicated by the fact that systematic data are collected only for crashes in which a fatality occurs. These data suffer from sample selection since seat belt and air bag usage influences survival rates which in turn determine whether a...

This essay reviews progress in empirical economics since Leamer's (1983) critique. Leamer highlighted the benefits of sensitivity analysis, a procedure in which researchers show how their results change with changes in specification or functional form. Sensitivity analysis has had a salutary but...

We consider the classic problem of estimating group treatment effects when individuals sort based on observed and unobserved characteristics that affect the outcome. Using a standard choice model, we show that controlling for group averages of observed individual characteristics potentially...

In this paper, we make a first attempt to explore the relationship between computer use and productivity in French manufacturing and services industries. We match information on computer utilization in the work place collected at the employee level in the years 1987, 1991 and 1993, with...

We revisit the minimum wage-employment debate, which is as old as the Department of Labor. In particular, we assess new studies claiming that the standard panel data approach used in much of the "new minimum wage research" is flawed because it fails to account for spatial heterogeneity. These...
