How Monopsonistic and Monopolistic Competition Affects Wage Disparities?
We develop a general equilibrium model in which firms employ different types of labor. Firms are endowed with market power that allows them to be price-makers and wage-setters. First, firms face upward sloping labor supplies because idiosyncratic non-pecuniary conditions interact with wages in workers’ decisions to work for specific firms. Second, we pin down the existence of a double exploitation of labor whose intensity depends on the interaction between the product and labor markets. Third, the heterogeneity within each type of labor implies that the high-productive workers tend to be overpaid, whereas the low-productive workers would be underpaid. However, intensifying competition on the goods market shrinks the discrepancy between wages and workers’ productivity. Last, we offer a theory of differential discrimination in which gender pay inequality varies with women’s family status.
