Abstract

This paper reassesses the wage curve applying regional price deflators, whereas in the literature only uniform national price levels are generally used in wage curve regressions. Existing estimates for the unemployment elasticities vary across countries but lie mostly in the neighborhood of −0.1. Using the data for the 49 US states over the 2008–2015 period and 16 Polish NUTS2 regions over the 2000–2015 period, we test the impact of regional prices on the wage curve employing a variety of approaches. We confirm the existence of wage curves for both countries. Following the theory of monopsonistic competition, this inverse relationship stems from the costs faced by both firms and workers. However, the elasticity of local unemployment and spatial spillovers decreases significantly if regional price deflators are applied. This is due to the fact that there exists a negative relationship between regional prices and unemployment.
