This paper contains a review of the early history of program evaluation research at the US Department of Labor. Some broad lessons for successful evaluation research are summarized.

A real wage rate is a nominal wage rate divided by the price of a good and is a transparent measure of how much of the good an hour of work buys. It provides an important indicator of the living standards of workers, and also of the productivity of workers. In this paper I set out the conceptual...

In this paper we report the results of the only field test of which we are aware that uses randomized trials to measure whether stricter enforcement and verification of work search behavior alone decreases unemployment claims and benefits paid in the U.S. unemployment insurance (UI) program....

In this essay I review Sylvia Nasar's long awaited new history of economics, Grand Pursuit. I describe how the book is an economic history of the period from 1850-1950, with distinguished economists' stories inserted in appropriate places. Nasar's goal is to show how economists work, but also to...

Virtually all public policies regarding taxation and the redistribution of income rely on explicit or implicit assumptions about the long run effect of wage rates on labor supply. The available estimates of the wage elasticity of male labor supply in the literature have varied between -0.2 and...

In 1987 the federal government permitted states to raise the speed limit on their rural interstate roads, but not on their urban interstate roads, from 55 mph to 65 mph for the first time in over a decade. Since the states that adopted the higher speed limit must have valued the travel hours...

In this paper we show that omitted variables and publication bias lead to severely biased estimates of the value of a statistical life. Although our empirical results are obtained in the context of a study of choices about road safety, we suspect that the same issues plague the estimation of...

Tradeoffs between monetary wealth and fatal safety risks are summarized in the value of a statistical life (VSL), a measure that is widely used for the evaluation of public policies in medicine, the environment, and transportation safety. This paper demonstrates the widespread use of this...

This brief survey contains a review of several new empirical papers that attempt to measure the extent of monopsony in labor markets. As noted originally by Joan Robinson, monopsonistic exploitation represents the gap between the value of a worker's marginal product and the worker's wage, and it...

A special exemption from the 1986 Age Discrimination Act allowed colleges and universities to enforce mandatory retirement of faculty at age 70 until 1994. We compare faculty turnover rates at a large sample of institutions before and after the federal law change, and at a set of institutions...
