Asymmetric effects across sectors are the distinctive features of the Covid-19 shock. Business Formation Statistics in the United States show a reallocation of entry and exit opportunities across sectors in the initial phase of the pandemic. To explain these facts, we propose an...

We show how to use Hurwitz polynomials to study the stability and uniqueness of Rational Expectation equilibria in Dynamic General Equilibrium models. We apply this method to a model characterized by staggered wage and price contracts and by limited asset market participation (LAMP). We prove...

This paper builds a New Keynesian industry dynamics model for the analysis of macroeconomic fluctuations and monetary policy. A continuum of heterogeneous firms populates the economy, markets are imperfectly competitive and nominal wages are sticky. An expansionary monetary policy shock triggers...

We propose a generalization of the rational expectations framework to allow for multiplicative sunspot shocks and temporarily unstable paths. Then, we provide an econometric strategy to estimate this generalized model on the data. Our approach yields drifting parameters and stochastic...

Is the typical specification of the Euler equation for investment employed in DSGE models consistent with aggregate macro data? Using state-of-the-art econometric methods that are robust to weak instruments and exploit information in possible structural changes, the answer is yes. Unfortunately,...

Since 2000 U.S. inflation has remained both below target and silent to domestic slack and monetary interventions. A trend-cycle BVAR decomposition explores the role of imported intermediate goods in explaining the puzzling behaviour of inflation. The trend analysis shows that, starting from the...

Structural models with no solution are incoherent, and those with multiple solutions are incomplete. We show that models with occasionally binding constraints are not generically coherent. Coherency requires restrictions on the parameters or on the support of the distribution of the shocks. In...

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...
