Knowledge that Transforms

A central question in labor economics and macroeconomics is whether the textbook competitive model provides an adequate representation of the labor market. Using longitudinal data on companies and establishments, this article suggests that it may not. As predicted by rent-sharing models of the labor market, changes in profitability are shown to feed through into long-run changes in wages. These are not temporary wage effects and are not driven by the unionized workplaces in the data. The article's estimates imply that, for rent-sharing reasons alone, Lester's "range" of wages is approximately 16%.

An econometric analysis demonstrates that television ratings for NBA games are substantially higher when certain players ('superstars') are involved. Thus, these superstars are quite important for generating revenue, not only for their own teams but for other teams as well. Using the econometric analysis and additional information on attendance and paraphernalia sales, the authors estimate the value of Michael Jordan to the other NBA teams to be approximately $53 million. The positive externality superstars have on other teams can lead to an inefficient distribution of player talent. The authors examine several league policies that might be used to address the externality. Copyright 1997 by University of Chicago Press.

I provide new evidence on the incidence of payroll taxation by examining the experience of Chile before and after the privatization of its Social Security system. This policy change led to a sharp exogenous reduction in the payroll tax burden on Chilean firms; on average, payroll tax rates fell by 25% over 6 years. Using data from a census of manufacturing firms, I estimate that the incidence of payroll taxation is fully on wages, with no effect on employment. This finding is robust to a variety of empirical approaches to the problem of measurement error in firm‐level measures of taxes/worker.

Using U.S. panel data on adult males, I compare the "profile heterogeneity model" of earnings dynamics, in which the earnings/experience profile varies across individuals, to a competing model in which earnings "has a unit root." The latter specification enjoys increasing popularity among researchers. My analysis questions this favor, suggesting the profile heterogeneity model provides a more consistent representation of the data. I also provide new estimates of the variation in earnings growth rates. Previous evidence is from relatively unrepresentative samples. Individuals one standard deviation above the mean enjoy a 20%-30% earnings advantage in just 10 years.

"This article investigates the role of surprises in marital dissolution [in the United States]. Surprises consists of changes in the predicted earning capacity of either spouse. Data from the National Longitudinal Study of the High School Class of 1972 is used. We find that an unexpected increase in the husband's earning capacity reduces the divorce hazard, while an unexpected increase in the wife's earning capacity raises the divorce hazard. Couples sort into marriage according to characteristics that are likely to enhance the stability of the marriage. The divorce hazard is initially increasing with the duration of marriage, and the presence of children and high levels of property stabilizes the marriage."

This article uses British firm-level panel data on actual innovative activity drawn from different statistical sources to identify the effect of technical change on jobs. Previous work tends to find positive associations of proxies for technical change and employment, but such studies suffer from various statistical drawbacks. In this study, even when one controls for fixed effects, dynamics, and endogeneity, innovations have a positive and significant effect on employment, which persists over several years. There seems to be little direct role for spillover effects from industry innovations, or any role for industry wages or union power.

This article examines the effect of Catholic secondary schooling on high school graduation rates, college graduation rates, and future wages. The article introduces new measures of access to Catholic schools that serve as potential instruments for Catholic school attendance. Catholic secondary schools are geographically concentrated in urban areas and Catholic schooling does increase educational attainment significantly among urban minorities. The gains from Catholic schooling are modest for urban whites and negligible for suburban students. Related analyses suggest that urban minorities benefit greatly from access to Catholic schooling primarily because the public schools available to them are quite poor.

This article analyzes the effect of trade liberalization on employment and wages in the Mexican manufacturing sector. The study documents that many of the rents generated by trade protection were absorbed by workers in the form of a wage premium. Trade liberalization affected firm‐level employment and wages by shifting down industry product and labor demand. This in itself may have accounted for a 3%–4% decline in real wages on average. But trade reform also reduced the rents available to be captured by firms and workers. This had an additional negative effect on firm‐level employment and wages.

Volunteer activity is work performed without monetary recompense. This article shows that volunteering is a sizeable economic activity in the United States, that volunteers have high skills and opportunity costs of time, that standard labor supply explanations of volunteering account for only a minor part of volunteer behavior, and that many volunteer only when requested to do so. This suggests that volunteering is a "conscience good or activity"-something that people feel morally obligated to do when asked, but which they would just as soon let someone else do.

This article examines the long-term wage and earnings losses of displaced workers using longitudinal data from the Panel Study of Income Dynamics. Consistent with previous research, the author finds that the effects of displacement are quite persistent, with earnings and wages remaining approximately 9 percent below their expected levels six or more years after displacement. She then shows that much of this persistence can be explained by additional job losses in the years following an initial displacement. Workers who avoid additional displacements have earnings and wage losses of 1 percent and 4 percent six or more years after job loss. Copyright 1997 by University of Chicago Press.
