This paper provides optimal labor and dividend income taxation in a general equilibrium model with oligopolistic competition and endogenous firms' entry. In the long run the optimal dividend income tax corrects for inefficient entry. The dividend income tax depends on the form of competition and...

This paper takes stock of the literature on the relationship between central bank policies and inequality. A new paradigm which integrates sticky-prices, incomplete markets and heterogeneity among households is emerging, which allows to jointly study how inequality shapes macroeconomic...

Using US annual data spanning four decades and several business cycles, we show that that job flow rates of young firms are more cyclical than those of mature firms and detect no difference between the cyclicality of job flow rates of small and large firms. Further, we find that job flow rates...

We study the impact of a General Purpose Technology that changes the cost structure turning fixed costs into variable ones in most sectors. A major recent example is cloud computing, whose adoption allows firms to avoid large up-front costs in IT and to rent computing capability online. We study...

The recent financial crisis has stimulated theoretical and empirical research on the propagation mechanisms underlying business cycles, in particular on the role of financial frictions. Many issues concerning the interactions between banking and monetary policy forced policy makers to redefine...

This paper provides an incomplete markets model with oligopolistic competition among an endogenous number of producers. The model matches the empirical distribution of income and wealth in the United States. The interaction between oligopolistic competition and incomplete markets reconciles the...

This paper introduces a New Keynesian multi-sector industry model that integrates firm heterogeneity, entry, and exit dynamics, while considering energy production from both fossil fuels and renewables. We investigate the effects of a sustained increase in fossil fuel prices on sectoral size,...
