INDUSTRY DYNAMICS AND THE MINIMUM WAGE: A PUTTY-CLAY APPROACH

We document two new findings about the industry-level response to minimum wage hikes. First, restaurant exit and entry both rise following a hike. Second, there is no change in employment among continuing restaurants. We develop a model of industry dynamics based on putty-clay technology that is consistent with these findings. In the model, continuing restaurants cannot change employment, and thus industry-level adjustment occurs gradually through exit of labor-intensive restaurants and entry of capital-intensive restaurants. Interestingly, the putty-clay model matches the small estimated short-run disemployment effect of the minimum wage found in other studies, but produces a larger long-run disemployment effect.
