This study compares the determinants of productivity and wages at both firm and worker level. In the firm-level analysis, we follow Hellerstein, Neumark and Troske (1999) and provide improved estimates based on an extended set of covariates including the intensity of firm-provided training. In...

We examine monthly variation in weekly work hours using data for 2003-10 from the Current Population Survey (CPS) on hours/worker, from the Current Employment Survey (CES) on hours/job, and from the American Time Use Survey (ATUS) on both. The ATUS data minimize recall difficulties and constrain...

We study the role of trade liberalization, democratization and their interaction for technology adoption. A general equilibrium theory with heterogeneous skills predicts a complementarity between trade and political regimes. Openness should accelerate technology adoption if coupled with...

In this paper we examine the degree to which Michigan's property value assessment growth cap has eroded the tax base and created substantial differences in effective tax rates among residential properties within the City of Detroit. While the analysis focuses on a specific city with significant...

In this paper we show that price equalization alone is not sufficient to determine the barriers to international trade. There are many barrier combinations that deliver price equalization, but each combination implies a different volume of trade. We demonstrate this first theoretically in a...

This paper aims to understand how corruption responds to an income loss. We exploit an unexpected 25% wage cut incurred in 2010 by all Romanian public sector employees, including the public education staff. We investigate a corruptible high-stake exam taking place shortly after the wage...

What happens to children's long-run cognitive development when introducing universal high-quality childcare for 3-year olds mainly crowds out maternal care? To answer this question we exploit a natural experiment framework and employ a difference-in-difference approach. We find sizable...

In the large literature on firm performance, economists have given little attention to entrepreneurs. We use deaths of more than 500 entrepreneurs as a source of exogenous variation, and ask whether this variation can explain shifts in firm performance. Using longitudinal data, we find large and...

Many countries are currently expanding access to child care for young children. But are all children equally likely to benefit from such expansions? We address this question by adopting a marginal treatment effects framework. We study the West German setting where high quality center-based care...
