Once upon a time, in the 1990s, it was widely agreed that neither Europe nor the United States was an optimum currency area, although moderating this concern was the finding that it was possible to distinguish a regional core and periphery (Bayoumi and Eichengreen, 1993). Revisiting these...

We take stock of the history of the European Monetary Union and pegged exchange-rate regimes in recent decades. The post-Bretton Woods greater financial integration and under-regulated financial intermediation have increased the cost of sustaining a currency area and other forms of fixed...

An optimum currency area is an economic unit composed of regions affected symmetrically by disturbances and between which labor and other factors of production flow freely. The symmetrical nature of disturbances and the high degree of factor mobility make it optimal to forsake nominal exchange...

The financial crises of the last twenty years brought new economic concepts into classrooms discussions. This article introduces undergraduate students and teachers to seven of these models: (i) misallocation of capital inflows, (ii) modern and shadow banks, (iii) strategic complementarities and...

We propose a simple model of the sovereign-bank diabolic loop, and establish four results. First, the diabolic loop can be avoided by restricting banks domestic sovereign exposures relative to their equity. Second, equity requirements can be lowered if banks only hold senior domestic sovereign...

This paper studies how capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market...

The international monetary system has passed through a succession of phases characterized alternatively by the dominance of fixed and flexible exchange rates. How are these repeated shifts between fixed and flexible rate regimes to be understood? The present paper specifies and tests six...

This paper investigates the changing pattern and efficacy of sterilization within emerging market countries as they liberalize markets and integrate with the world economy. We estimate the marginal propensity to sterilize foreign asset accumulation associated with net balance of payments...

This paper studies the welfare effects of financial integration in the presence of moral hazard. Entrepreneurs face a trade off between risk and return. Banks may mitigate the resultant excessive risk by costly monitoring, where greater risk reduction requires more resources devoted to risk...

We use data on the extent to which residents of one country hold the bonds of issuers resident in another as a measure of financial integration or interrelatedness, asking how Asia compares with Europe and Latin America and with the base case in which the purchaser and issuer of the bonds reside...
