In a dynamic general equilibrium model with endogenous markups and labor market frictions, we investigate the effects of increased product market competition. Unlike most macroeconomic models of search, we endogenize the labor supply along the extensive margin. We show that beneficial effects in...

We examine the determinants of income inequality and mobility in a Ramsey model with elastic labor supply. Individuals differ both in their initial capital endowment and productive ability (labor endowment). With two sources of heterogeneity, initially poorer agents may catch up with the income...

We examine how changes in tax policies affect the dynamics of the distributions of wealth and income in a Ramsey model in which agents differ in their initial capital endowment. The endogeneity of the labor supply plays a crucial role in determining inequality, as tax changes that affect hours...
