In search of labor demand

Abstract

We propose and estimate a novel specification of labor demand which encompasses search frictions and the role of entrepreneurs in new firm creation. Using city-industry variation over four decades, we estimate the wage elasticity of employment demand to be close to -1 at the industry-city level and -0.3 at the city level. We argue that the difference between these estimates reflects the congestion externalities predicted by the search literature. Our estimates also indicate that entrepreneurship should be treated as a scarce factor in the determination of labor demand. We use our estimates to evaluate the impact of large changes in the minimum wage on employment.
