We develop a model with financial frictions and sovereign default risk where the maturity of public debt is allowed to be larger than one period. When the debt portfolio has longer average maturities, public debt increases less in the event of a crisis, reducing the size of the subsequent fiscal...

We quantify the effects of competitive tax reforms within a two-country monetary union model with endogenous entry and endogenous tradability. As expected, their effects on out-put, consumption, hours worked and the terms of trade are positive. Extensive margins provide additional transmission...

In this paper, we measure the welfare costs/gains associated with financial market incompleteness in a monetary union. To do this, we build on a two-country model of a monetary union with sticky prices subject to asymmetric productivity shocks. For most plausible values of price stickiness, we...

This paper examines if taking into account changes in the number of producers, or equivalently changes in the product variety space over the business cycle, helps to understand and replicate international business cycle facts. To this end, we develop a two-country model in which the economy is...

This paper evaluates the welfare gains arising from a deeper trade integration in the European Monetary Union. To do this, the European Monetary Union is represented in a realistic way by an intertemporal general equilibrium model with incomplete financial markets, sticky prices and home bias...

How to explain rising income and wealth inequality? We build an original heterogeneous-agent model with three key features: (i) an explicit link between firm's market power and top income shares, (ii) a granular representation of the tax and transfer system, and (iii) three assets with...
