What can be learnt from revisiting the Optimal Currency Areas (OCA) theory 50 years from its birth, in light of recent advances in open economy macro and monetary theory? This paper presents a stylized micro-founded model of the costs of adopting a common currency, relative to an ideal benchmark...

The paper reviews the arguments for and against monetary union among the six members of the Gulf Cooperation Council - the United Arab Emirates, the State of Bahrain, the Kingdom of Saudi Arabia, the Sultanate of Oman, the State of Qatar and the State of Kuwait. Both technical economic arguments...

This paper offers empirical evidence that real exchange rate volatility can have a significant impact on long-term rate of productivity growth, but the effect depends critically on a country's level of financial development. For countries with relatively low levels of financial development,...

This Paper considers how an international lender of last resort can prevent self-fulfilling banking and currency crises in emerging economies. We compare two different arrangements: one in which the international lender of last resort injects international liquidity into financial markets, and...

Although there seems to be a broad consensus among economists that purely floating or completely fixed exchange rates (the so-called corner solutions) are the only viable alternatives of exchange rate management, many countries do not behave according to this paradigm and adopt a strategy within...

Transition was never going to be easy, even if the long-run outlook is highly promising. Not only was the process itself a major theoretical and policy challenge but, inevitably, politics and economics were bound to interfere. With some spectacular exceptions, most countries are now on the right...

We use a sample of 140 countries to study empirically how a country's characteristics are associated with its choice of an exchange rate regime. When countries are classified according to their current exchange rate arrangements, we observe that small countries with low diversification of...

This paper uses a two-country overlapping generations model to study the international transmission of fiscal policy among open interdependent economies under free international capital mobility. With only lump-sum taxes and transfers, international transmission involves only pecuniary...

We provide empirical evidence that risk sharing enhances specialization in production. To the best of our knowledge, this well-established and important theoretical proposition has not been tested before. Our empirical procedure is summarized as follows. First, we construct a measure of...

The Paper extends Woodford’s (2000) analysis of the closed economy Phillips curve to an open economy with both commodity trade and capital mobility. We show that consumption smoothing, which comes with the opening of the capital market, raises the degree of strategic complementarity among...
