Knowledge that Transforms

This article reports on household survey measurements of the “offshorability” of jobs, defined as the ability to perform the work from abroad. We develop multiple measures of offshorability, using both self-reporting and professional coders. All measures find that roughly 25% of US jobs are offshorable. Our three preferred measures agree between 70% and 80% of the time. Professional coders appear to provide the most accurate assessments. Empirically, more educated workers appear to hold somewhat more offshorable jobs, and offshorability does not have systematic effects on either wages or the probability of layoff.

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.

Based on a survey of 1, 268 firms in 12 cities, this article empirically studies unions' effects on worker welfare in China. Regressions carried out on a rich set of specifications show that unionization is significantly associated with higher hourly wages and larger pension coverage and weakly associated with lower monthly working hours. Further econometric analysis finds that unions promote individual and collective contracts. The effect of collective contracts vanishes when unions are present, whereas individual contracts have independent and positive effects. In addition, unions have effects on workers' welfare independent of collective and individual contracts.
