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...

In this paper we study jointly optimal ¯scal and monetary policies in a small open economy framework with capital and sticky prices. We consider the case of distor- tionary taxes on labor and capital, and no public debt. As in a closed economy set{up, in the steady state, the optimal in°ation...

In this paper, we bridge economic data and climatic time series to assess the vulnerability of a pre-industrial economy to changes in climatic conditions. We propose an economic model to extract a measure of total productivity from English data (real wages and land rents) in the pre-industrial...

We show that welfare can be lower under complete financial markets than under autarky in a monetary union with home bias, sticky prices and asymmetric shocks. Such a monetary union is a second-best environment in which the structure of financial markets affects risk-sharing but also shapes the...

We show that the welfare costs of business cycles in a monetary union can be higher under incomplete financial markets than under complete markets. A monetary union with home bias, sticky prices and country-specific shocks is a second-best environment in which the structure of financial markets...

Cet article propose une extension du cadre de travail théorique proposée par Bilbiie, Ghironi et Melitz [2007] en économie ouverte afin d'étudier les effets de la politique monétaire sur marges intensives et extensives sur l'activité économique. Deux régimes de politique monétaire sont...

This paper proposes a conceptual framework to investigate the impact of military conflicts on business cycles, as well as defense policies through enrolment mechanisms. Our framework is a variation of a Real Business Cycle model first proposed by Hercowitz and Sampson (1991) that admits explicit...

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 shows that in a monetary union the interest rate rule of the Central Bank should react to the in°ation rate of the Harmonized Index of Consumption Price (HICP) rather than to the inflation rate of the Welfare-Based Consumption Price (WBCP). In a two{country general equilibrium model...
