Wages have been spreading out across workers over time - or in other words, the 90th/50th wage ratio has risen over time. A key question is, has the productivity distribution also spread out across worker skill levels over time? Using our calculations of productivity by skill level for the U.S.,...

We study the effects of the unionization of faculty at Canadian universities from 1970-2022 using an event-study design. Using administrative data which covers the full universe of faculty salaries, we find strong evidence that unionization leads to both average salary gains and compression of...

The recent shift to remote work raised the amenity value of employment. As compensation adjusts to share the amenity-value gains with employers, wage-growth pressures moderate. We find empirical support for this mechanism in the wage-setting behavior of U.S. employers, and we develop novel...

We show that time variation in risk premia leads to time-varying idiosyncratic income risk for workers. Using US administrative data on worker earnings, we show that increases in risk premia lead to lower earnings for low-wage workers; these declines are primarily driven by job separations. By...

Most economists maintain that the labor market in the United States is 'tight' because unemployment rates are low. They infer from this that there is potential for wage-push inflation. However, real wages are falling rapidly at present and, prior to that, real wages had been stagnant for some...

We analyze the economic consequences of rising health care prices in the US. Using exposure to price increases caused by horizontal hospital mergers as an instrument, we show that rising prices raise the cost of labor by increasing employer-sponsored health insurance premiums. A 1% increase in...

We study the importance of firm sorting for spatial inequality. If productive locations are able to attract the most productive firms, then firm sorting acts as an amplifier of spatial inequality. We develop a novel model of spatial firm sorting, in which heterogeneous firms first choose a...

This paper is about the nonparametric regression of a choice variable on a nonlinear budget set under utility maximization with general heterogeneity, i.e. in the random utility model (RUM). We show that utility maximization and convex budget sets make this regression three dimensional with a...

We provide semiparametric identification results for a broad class of learning models in which continuous outcomes depend on three types of unobservables: i) known heterogeneity, ii) initially unknown heterogeneity that may be revealed over time, and iii) transitory uncertainty. We consider a...

Low unionization rates, a falling real federal minimum wage, and outsourcing have hampered wage growth in the low-wage sector in the US. In recent years, a number of private employers have opted to institute or raise company-wide minimum wages for their employees, sometimes in response to public...
