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 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...

We examine the implications of high degrees of dollarization for the choice of exchange rate regime and the information content of various monetary aggregates in developing countries. We conclude that a high degree of currency substitution argues for a more fixed exchange rate regime, while...

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...

The currency board arrangement (CBA) in Bulgaria will soon mark its twenty fifth anniversary, a period full of important policy challenges and difficult choices for the policymakers. This paper summarizes the evolution of Bulgaria’s macroeconomic policy set under this monetary and exchange...

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...

The paper builds a two-country model of a monetary union with home bias and price stickiness. Incompleteness of financial asset markets is allowed. In this environment, we derive the solution for optimal behavior by the monetary policymaker and show that welfare can be higher under incomplete...
