Using a unique data set on teachers’ union election certifications from Iowa, Indiana, and Minnesota, I estimate the effect of teachers’ unions on school district resources and on student educational attainment. My empirical strategy allows for nonparametric leads and lags of union age. I find no impact on teacher pay or per student district expenditures but that unions increase teacher employment by 5%. I find no class size effect because of enrollment increases in unionized districts, and I estimate that unions have no net effect on high school dropout rates. These findings highlight the importance of correctly measuring unionization status.

I present the fact that wage gaps due to firm size increase with job responsibility. I use Swedish data to determine whether wage gaps increase with a direct measure of job responsibility, to compare the age patterns of the wage gaps for blue‐ and white‐collar workers, and to compare wages by job responsibility and spans of control. With U.S. data, I compare supervisory to nonsupervisory occupations and find that wage gaps increase with job responsibility for most occupational ladders. This fact is consistent with hierarchical matching models in which the larger number of subordinates amplifies managerial talent.

This article exploits a quasi‐experimental setting to estimate the impact that a commonly used performance‐related pay scheme had on branch performance in a large distribution firm. The scheme, which is based on the Balanced Scorecard, was implemented in all branches in one division but not in another. Branches from the second division are used as a control group. Our results suggest that the Balanced Scorecard had some impact but that it varied with branch characteristics, and, in particular, branches with more experienced managers were better able to respond to the new incentives.

This article presents evidence about the effects of dismissals‐for‐cause requirements, a specific component of employment protection legislation that has received little attention. I study a quasi‐experiment generated by a law introduced in Portugal: out of the 12 paragraphs in the law that dictated the costly procedure required for dismissals for cause, eight did not apply to small firms. Using matched employer‐employee longitudinal data and difference‐in‐differences methods, I examine the impact of that differentiated change in firing costs upon several variables. The results do not indicate robust effects on job or worker flows, although some estimates suggest an increase in hirings. However, firms that gain flexibility in their dismissals exhibit sizable increases in their relative performance. This finding suggests that reducing firing costs of the type studied here increases workers’ effort.

We study the effects of surname change to Swedish‐sounding or neutral names on earnings for immigrants from Asian/African/Slavic countries. To estimate this effect, we exploit the variation resulting from different timing of name changes across individuals during the 1990s. The results imply that there is a substantial increase in annual earnings after a name change, no effects on earnings prior to a name change, and no positive general effects of a new name for other groups that renounced a foreign name. Based on these findings, we argue that these effects are due to name change as a response to discrimination.

Using personnel data from a large U.S. retail firm, we examine whether the race or ethnicity of the hiring manager affects the racial composition of new hires. We exploit manager turnover to estimate models with store fixed effects and store-specific trends. First, we find that all nonblack managers-that is, whites, Hispanics, and Asians-hire more whites and fewer blacks than do black managers. This is especially true in the South. Second, in locations with large Hispanic populations, Hispanic managers hire more Hispanics and fewer whites than do white managers. We also examine possible explanations for these differential hiring patterns. (c) 2009 by The University of Chicago. All rights reserved.

This article studies the effect of changes in foreign competition on the structure of compensation and incentives of U.S. executives. We find that import penetration (instrumented with exchange rates and tariffs) leads to more incentive provision in a variety of ways. First, it increases the sensitivity of pay to performance. Second, it increases within-firm pay differentials between executive levels, with CEOs typically experiencing the largest wage increases. Finally, higher foreign competition is also associated with a higher demand for talent. These results suggest that increased foreign competition can explain some of the recent trends in compensation structures. (c) 2009 by The University of Chicago. All rights reserved.

We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools, which we argue are formed roughly randomly. The estimates are much reduced within schools compared to the standard ordinary least squares (OLS) results. This could be explained either by selection into schools or by measurement error in the peer variable. Correcting for measurement error, we find within‐school estimates close to the original OLS estimates. Our results suggest that the peer effect is modestly large, measurement error is important in our survey data, and selection plays little role in biasing peer effects estimates.

Uncovering the effect of school racial composition is difficult because racial mixing is not accidental but instead an outcome of government and family choices. Using rich panel data on the achievement of Texas students, we disentangle racial composition effects from other aspects of school quality and from differences in abilities and family background. The estimates strongly indicate that a higher percentage of black schoolmates reduces achievement for blacks, while it implies a much smaller and generally insignificant effect on whites. These results suggest that existing levels of segregation in Texas explain a small but meaningful portion of the racial achievement gap.
