Knowledge that Transforms

We examine the effects of minimum wage legislation in Canada over the period 1975–93. For teenagers we find that a 10% increase in the minimum wage is associated with roughly a 2.5% decrease in employment. We also find that this result is driven by low frequency variation in the data. At high frequencies the elasticity is positive and insignificant. The difference in the elasticity across the bandwidth has implications for the interpretation of employment dynamics as a result of minimum wage policy and experimental design in minimum wage studies. It also provides a simple reconciliation of the “new minimum wage research,” which reports very small negative, or positive, elasticities.

The model of job search involves both employer matches and career matches. Workers may change employers without changing careers but cannot search over possible lines of work while working for one employer. The optimal policy implies a two‐stage search strategy in which workers search over types of work first. The patterns of job changes observed in the National Longitudinal Survey of Youth support this two‐stage search policy. Among male workers who are changing jobs, those who have previously changed employers while working in their current career are much less likely to change careers during the current job change.

We use a unique new data set that combines data on individual workers and their employers to estimate marginal productivity differentials among different types of workers. We then compare these to estimated relative wages, leading to new evidence on productivity‐based and nonproductivity‐based explanations of the determination of wages. Among our findings are (1) the higher pay of prime‐aged workers (aged 35–54) and older workers (aged 55+) is reflected in higher point estimates of their relative marginal products, and (2) for the most part, the lower relative earnings of women are not reflected in lower relative marginal products.

This article adds to the empirical literature on tournament theory as a theory of executive compensation. I test several propositions of tournament models on a rich data set containing information about 2,600 executives in 210 Danish firms during a 4‐year period. I ask, Are pay differentials between job levels consistent with relative compensation? Is pay dispersion between levels higher in noisy environments? Is the dispersion affected by the number of tournament participants? Is average pay lower in firms with more compressed pay structures? Does wider pay dispersion enhance firm performance? Most of the predictions gain support in the data.

This article investigates if the location choices made by immigrants when they arrive in the United States are influenced by the interstate dispersion in welfare benefits. Income-maximizing behavior implies that foreign-born welfare recipients, unlike their native-born counterparts, may be clustered in the states that offer the highest benefits. The empirical analysis indicates that immigrant welfare recipients are indeed more heavily clustered in high-benefit states than the immigrants who do not receive welfare, or than natives. As a result, the welfare participation rate of immigrants is much more sensitive to changes in welfare benefits than that of natives.

Estimates from the Panel Study of Income Dynamics indicate that African-American men are one-third as likely to be self-employed as white men. The large discrepancy is due to a black transition rate into self-employment that is approximately one-half the white rate and a black transition rate out of self-employment that is twice the white rate. Using a new variation of the Blinder-Oaxaca decomposition technique, the author finds that racial differences in asset levels and probabilities of having self-employed fathers explain a large part of the gap in the entry rate, but almost none of the gap in the exit rate.

Editor's Note Our policy is to annotate all English-language books on economics and related subjects that are sent to us. A very small number of foreign-language books are called to our attention and annotated by our consulting editors or others. Our staff does not monitor and order books published; therefore, if an annotation of a book does not appear six months after the publication date, please write to us or the publisher concerning the book. An Index of Authors of New Books appearing in the Annotated Listings will appear at the end of the General Index in the December issue.
