Are Shirking and Leisure Substitutable? An Empirical Test of Efficiency Wages Based on Urban Economic Theory

Recent theoretical work has examined the spatial distribution of unemployment using the efficiency wage model as the mechanism by which unemployment arises in the urban economy. This paper extends the standard efficiency wage model in order to allow for behavioral substitution between leisure time at home and effort at work. In equilibrium, residing at a location with a long commute affects the time available for leisure at home and therefore affects the trade-off between effort at work and risk of unemployment. This model implies an empirical relationship between expected commutes and labor market outcomes, which is tested using the Public Use Microdata sample of the 2000 U.S. Decennial Census. The empirical results suggest that efficiency wages operate primarily for blue collar workers, i.e. workers who tend to be in occupations that face higher levels of supervision. For this subset of workers, longer commutes imply higher levels of unemployment and higher wages, which are both consistent with shirking and leisure being substitutable.

Do Labor Market Imperfections Increase Trade Protection? A Theoretical Investigation

Labor market imperfections are commonly believed to be a major reason for imposing trade impediments. In this paper, I introduce labor market rigidities that are prevalent in continental European countries into the well-known protection for sale model proposed by Grossman and Helpman (1994). I show that contrary to commonly held views, imperfections in the labor market do not necessarily increase equilibrium trade protection. A testable equilibrium trade protection equation is also derived. The findings in this paper are hence particularly relevant for empirical tests of trade policy determinants in economies with more regulated labor markets.
