Markups and Inequality


We study the aggregate and distributional impact of product market interventions and profit taxes using a model of firm dynamics, credit constraints and incomplete markets. A key ingredient of our model is that markups are endogenous so that the markup a producer charges depends on the amount of competition it faces. We show that size-dependent subsidies that remove the distortions due to markup dispersion lead to sizable welfare gains and reduce inequality, even though they increase firm concentration and long-run misallocation. In contrast, policies that reduce concentration lead to large output, TFP and welfare losses and increase inequality. A tax on profits greatly depresses the incentives to create new firms, reducing labor demand, after-tax wages and welfare.
