Knowledge that Transforms

In 2004, the Chicago Public Schools and the Chicago Teachers Union signed a new collective bargaining agreement that gave principals the flexibility to dismiss probationary teachers (those with fewer than 5 years of experience) for any reason and without the hearing process typical in many urban districts. Results suggest that the policy reduced annual teacher absences by roughly 10% and reduced the incidence of frequent absences by 25%. The majority of the effect was due to changes in the composition of teachers in the district, although there is evidence of modest incentive effects for young untenured teachers.

This article tests whether the correlation between wages and concentration of employment can be explained by unobserved worker productivity. Residential location is used as a proxy for unobserved productivity, and average commute time to workplace is used to test whether location-based productivity differences are compensated away by longer commutes. Analyses using confidential data from the 2000 Decennial Census find that estimates of agglomeration wage premia within metropolitan areas are robust to comparisons within residential location and that estimates do not persist after controlling for commuting costs, suggesting that the productivity differences across locations are due to location, not individual unobservables.

Using a large data set that links individual Current Population Survey (CPS) records to employer-reported administrative data, we document substantial discrepancies in basic measures of employment status that persist even after controlling for known definitional differences between the two data sources. We hypothesize that reporting discrepancies should be most prevalent for marginal workers and for marginal or nonstandard jobs, and we find systematic associations between the incidence of reporting discrepancies and observable person and job characteristics that are consistent with this hypothesis. The paper discusses the implications of the reported findings for both micro and macro labor market analysis.

This paper extends the job creation–job destruction approach to the labor market to take into account a deterministic finite horizon. As hirings and separations depend on the time over which investment costs can be recouped, the life-cycle setting implies age-differentiated labor-market flows. While search by the unemployed falls with age, the separation rate is rather U-shaped over the life cycle. Worker heterogeneity in the context of undirected search implies an intergenerational externality, which is not eliminated by the Hosios condition. We show that age-specific policies are required to attain the first-best allocation.

We present a theoretical and empirical analysis of internal promotion versus external recruitment, using a job-assignment model involving competing firms with heterogeneous productivities and two-level job hierarchies with one managerial position. The model predicts that, controlling for the number of managers, increasing the number of lower-level workers is associated with (1) greater internal promotion as opposed to external recruitment, (2) higher profit, and (3) more general training. Empirical analysis of a large cross section of British employers is consistent with these predictions.

We use Michigan Panel Study of Income Dynamics data and data from a 2008 telephone survey of adults conducted by Westat for the Princeton Data Improvement Initiative (PDII) to explore the importance and feasibility of adding retrospective questions about actual work experience to cross-sectional data sets. We demonstrate that having such actual experience data is important for analyzing women’s postschool human capital accumulation, residual wage inequality, and the gender pay gap. Further, our PDII survey results show that it is feasible to collect actual experience data in cross-sectional telephone surveys like the March Current Population Survey’s annual supplement.

I examine the effects of cognitive ability and personality traits on college graduation in a recent cohort of young Americans, and how the returns to these traits vary by family background, and find very substantial differences across family background groups in the personality traits that predict successful completion of college, particularly for men. The implications are twofold. First, the returns to noncognitive traits may be highly context dependent. Second, policy discussion concerning educational inequality should include not just the possibilities for remediating the skill levels of poor children, but also approaches to changing the environments that limit their opportunities.

Teacher compensation schemes are often criticized for lacking a performance-based component. Proponents argue that teacher incentive pay can raise student achievement and stimulate system-wide innovation. We examine a group-based teacher incentive scheme implemented in New York City and investigate whether specific features of the program contributed to its ineffectiveness. Although overall the program had little effect on student achievement, we show that in schools where incentives to free ride were weakest, the program led to small increases in math achievement. Our results underscore the importance of carefully considering the design of teacher incentive pay programs.

This study establishes empirically a positive but nonlinear relationship between weekly hours and hourly wage growth. For workers who put in over 47 hours per week, 5 extra hours are associated with a 1% increase in annual wage growth. This correlation is not present when hours are lower. The relationship is especially strong for young professionals. Data on promotions provide evidence in support of a job-ladder model that combines higher skill sensitivity of output in higher-level jobs with heterogeneous preferences for leisure. The results can be used to account for part of the gender wage gap.

We explore how the availability of affordable live-in help provided by foreign domestic workers (FDWs) in Hong Kong affected native women’s labor supply and welfare. First, we exploit differences in the FDW program between Hong Kong and Taiwan. Second, we use cross-sectional variation in the cost of a FDW to estimate a model of labor force participation and FDW hire. FDWs increased the participation of mothers with a young child (relative to older children) by 10–14 percentage points and have generated a monthly consumer surplus of US130–US200. By reducing child care costs through immigration, this is a market-based alternative to child care subsidies.
