In the year 2003 alone, the American Economic Review published 14 articles reporting regression analyses involving individual or family income variables, and the May Papers and Proceedings issue contained almost that many again. In some cases, the income variables were dependent variables; in others, they were regressors used to explain dependent variables(More)
Several recent studies have found that earnings inequality in Canada has grown considerably since the late 1970’s. Using an extraordinary data base drawn from longitudinal income tax records, we decompose this growth in earnings inequality into its persistent and transitory components. We find that the growth in earnings inequality reflects both an increase(More)
We provide new estimates of the return to job seniority using data similar to that used by Abraham and Farber (1987), Altonji and Shakotko (1987) and Topel (1991) as well as a more recent PSID sample. We consider the pluses and minus of the studies’ treatment of economy trends, the dating convention for tenure and wages, the handling of wage observations(More)
School choice has become an increasingly prominent strategy for enhancing academic achievement. To evaluate the impact on participants, we exploit randomized lotteries that determine high school admission in the Chicago Public Schools. Compared to those students who lose lotteries, students who win attend high schools that are better in a number of(More)
Several recent studies, including the Rouse (1999) and Behrman & Rosenzweig (1999) articles in this issue, use the schooling and wage variation between monozygotic twins to estimate the return to schooling. In this overview article, we summarize the results from this literature, and we examine the implications of endogenous determination of which twin goes(More)
The standard revealed-preference estimate of a city’s quality of life is proportional to that city’s cost-of-living relative to its wage-level. Adjusting estimates to account for federal taxes, nonhousing costs, and non-labor income produces more plausible quality-of-life estimates than in the previous literature. Unlike previous estimates, adjusted(More)
Government policies increasingly promote ethanol for security, air quality, and climate benefits. I develop a model that links household preferences for ethanol as a gasoline substitute to aggregate price responses. I estimate the model using data from many retail fueling stations. Ethanol demand is sensitive to relative fuel prices with a mean elasticity(More)
The purpose of this paper is to help empirical economists think through when and how to weight the data used in estimation. We start by distinguishing two purposes of estimation: to estimate population descriptive statistics and to estimate causal effects. In the former type of research, weighting is called for when it is needed to make the analysis sample(More)
