In this article we show that the quality of the vintage for red Bordeaux wines, as judged by the prices of mature wines, can be predicted by the weather during the growing season that produced the wines. Red Bordeaux wines have been produced in the same place and much the same way for hundreds...

In early 2003, France actively tried to thwart the plans of the Bush administration to build international support for a war to depose Iraqi ruler Saddam Hussein. In response, calls in the United States for a boycott of French products, wine in particular, rebounded through all forms of media....

In this paper we set out some methods that utilize the longitudinal structure of earnings of trainees and a comparison group to estimate the effectiveness of training for the 1976 cohort of CETA trainees. By fitting a components-of-variance model of earnings to the control group, and posing a...

In this paper we study the complete evolution of a final-offer arbitration system used in New Jersey with data we have systematically collected over the 18-year life of the program. Covering the wages of police officers and firefighters, this system provides virtually a laboratory setting for...

We develop a model of optimal schooling investments and estimate it using new data on approximately 700 identical twins. We estimate an average return to schooling of 9 percent for identical twins, but estimated returns appear to be slightly higher for less able individuals. Simple cross-section...

This paper uses a new survey to contrast the wages of genetically identical twins with different schooling levels. Multiple measurements of schooling levels were also collected to assess the effect of reporting error on the estimated economic returns to schooling. The data indicate that omitted...

Since 1941, six Executive Orders have been issued forbidding Federal government contractors from discriminating against minority workers. In principle, all prospective contractors are required to demonstrate compliance with the law before a contract is let. The potential penalties are severe:...

This article reports nonparametric estimates of the effect of labor-supply behavior on the payments to families enrolled in the Seattle/Denver Income Maintenance Experiment. The randomized assignment of families to the treatment groups in this experiment was designed to permit the calculation of...

In the last two decades, U.S. policies have moved from the use of incentives to the use of sanctions to promote work effort in social programs. Surprisingly, except for anecdotes, there is very little systematic evidence of the extent to which sanctions applied to the abusive use of social...
