The paper starts with the assumption that the Mercosur countries have decided to pursue monetary integration. These countries have essentially two options: a decentralized monetary union (MU) whereby each member country either pegs to the U.S. dollar or dollarizes outright; or a centralized MU...

We propose a new and time-varying optimum currency area (OCA) index for the euro area in assessing the evolution of the OCA properties of the monetary union from an international business cycle perspective. It is derived from the relative importance of symmetric vs. asymmetric shocks that result...

Differential requirements for seigniorage provide a weak case for retaining monetary independence. As regards adjustment to asymmetric shocks, nominal exchange rate flexibility is at best a limited blessing and at worst a limited curse. Absence of significant fiscal redistribution mechanisms...

A currency union is when several independent sovereign nations share a common currency. This has been a recurring phenomenon in monetary history. In this article I study the theoretical foundations of such unions, and discuss some important currency unions in history, most notably the case of...

This research note discusses the Euro crisis in Greece in light of the referendum of July the 5th. It lays out the social and political costs of a GREXIT, but also of a continuing austerity policy. It proposes a reform policy fostering growth in Greece and discusses the role of conditionality....

This paper shows that currency arrangements impact on credit available through default incentives. To this end we build a symmetric two-country model with money and imperfect credit market integration. With the Euro Area context in mind, we capture differences in credit market integration by...

The paper analyses the common European monetary policy based on a Mises-Hayek overinvestment framework, which is combined with the theory of optimum currency areas. It shows how since the turn of the millennium a too expansionary monetary policy contributed to unsustainable overinvestment booms...

This paper studies the welfare impact of a common monetary policy in the context of a two-country, general equilibrium model with liquidity effect and nominal wage contracts, heterogeneous agents, imperfect competition in the labor market, trade in goods, immobility of labor and mobility of...
