Knowledge that Transforms

This paper investigates married women’s hours worked disaggregated by the husband’s wage decile. In the United States, this pattern has changed from downward sloping to hump shaped. We show that this development can be explained within a standard household model of labor supply when taking into account trends in assortative mating. A quantitative analysis of our model shows that female wage growth and decreasing fertility are primarily responsible for the overall increase in wives’ hours since the 1970s. The fact that the most pronounced increases are observed for wives married to high-wage men is a result of trends in assortative mating.

This article studies how decentralization of wage bargaining from sector to firm level influences wage levels and wage dispersion. We use detailed panel data covering a period of decentralization in the Danish labor market. The decentralization process provides variation in the individual worker’s wage-setting system that facilitates identification of the effects of decentralization. We find a wage premium associated with firm-level bargaining relative to sector-level bargaining and that the return to skills is higher under the more decentralized wage-setting systems. Using quantile regression, we also find that wages are more dispersed under firm-level bargaining compared to more centralized wage-setting systems.

We develop an equilibrium model of the US labor market, fit to Panel Study of Income Dynamics data from 1968–96. Our main innovation is a finer differentiation of types of labor than in prior work (i.e., by occupation, education, gender, and age). This lets us fit wage and employment patterns better than simpler models. We obtain a good fit to wages and occupational choices over the 29-year period while also explaining college attendance rates. We use the model to assess factors driving changes in the wage structure. Occupational demand shifts and shifts in demand for college labor and female labor within occupations are key factors.

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.
