TL;DR: A theory of optimum currency areas is proposed in this paper, where the authors argue that periodic balance-of-payments crises will remain an integral feature of the international economic system as long as fixed exchange rates and rigid wage and price levels prevent the terms of trade from fulfilling a natural role in the adjustment process.
Abstract: It is patently obvious that periodic balance-of-payments crises will remain an integral feature of the international economic system as long as fixed exchange rates and rigid wage and price levels prevent the terms of trade from fulfilling a natural role in the adjustment process. It is, however, far easier to pose the problem and to criticize the alternatives than it is to offer constructive and feasible suggestions for the elimination of what has become an international disequilibrium system.' The present paper, unfortunately, illustrates that proposition by cautioning against the practicability, in certain cases, of the most plausible alternative: a system of national currencies connected by flexible exchange rates. A system of flexible exchange rates is usually presented, by its proponents,2 as a device whereby depreciation can take the place of unemployment when the external balance is in deficit, and appreciation can replace inflation when it is in surplus. But the question then arises whether all existing national currencies should be flexible. Should the Ghanian pound be freed to fluctuate against all currencies or ought the present sterling-area currencies remain pegged to the pound sterling? Or, supposing that the Common Market countries proceed with their plans for economic union, should these countries allow each national currency to fluctuate, or would a single currency area be preferable? The problem can be posed in a general and more revealing way by defining a currency area as a domain within which exchange rates are fixed and asking: What is the appropriate domain of a currency area? It might seem at first that the question is purely academic since it hardly appears within the realm of political feasibility that national currencies would ever be abandoned in favor of any other arrangement. To this, three answers can be given: (1) Certain parts of the world are undergoing processes of economic integration and disintegration, new experiments are being made, and a conception of what constitutes an optimum currency area can clarify the meaning of these experiments. (2) Those countries, like Canada, which have experimented with flexible exchange rates are likely to face particular problems which the theory of optimum currency areas can elucidate if the national currency area does not coincide with the optimum currency area. (3) The idea can be used to illustrate certain functions of currencies which have been inadequately treated in the economic literature and which are sometimes neglected in the consideration of problems of economic policy.

TL;DR: This paper used a gravity model to assess the separate effects of exchange rate volatility and currency unions on international trade and found that currency unions like the European EMU may lead to a large increase in international trade, with all that that entails.
Abstract: Currency unions Their dramatic effect on international trade A gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade. The panel data, bilateral observations for five years during 1970–90 covering 186 countries, includes 300+ observations in which both countries use the same currency. I find a large positive effect of a currency union on international trade, and a small negative effect of exchange rate volatility, even after controlling for a host of features, including the endogenous nature of the exchange rate regime. These effects, statistically significant, imply that two countries sharing the same currency trade three times as much as they would with different currencies. Currency unions like the European EMU may thus lead to a large increase in international trade, with all that that entails. — Andrew Rose

TL;DR: In this article, the authors examine the empirical evidence on currency crises and propose a specific early warning system, which involves monitoring the evolution of several indicators that tend to exhibit an unusual behavior in the periods preceding a crisis.
Abstract: This paper examines the empirical evidence on currency crises and proposes a specific early warning system. This system involves monitoring the evolution of several indicators that tend to exhibit an unusual behavior in the periods preceding a crisis. When an indicator exceeds a certain threshold value, this is interpreted as a warning "signal" that a currency crisis may take place within the following 24 months. The variables that have the best track record within this approach include exports, deviations of the real exchange rate from trend, the ratio of broad money to gross international reserves, output, and equity prices.

Abstract: A gravity model is used to asses the separate effects of exchange rate volatility and currency unions on international trade. The panel data set I use includes bilateral observations for five years spanning 1970 through 1990 for 186 countries. In this data set, there are over one hundred pairings and three hundred observations, in which both countries use the same currency. I find a large positive effect of a currency union on international trade, and a small negaitve effect of exchange rate volatility, even after controlling for a host of features, including the endogenous nature of the exchange rate regime. These effects are statistically significant and imply that two countries that share the same currency trade three times as much as theoy would with different currencies. EMU may thus lead to a large increase in internationel trade, with all that entails.

TL;DR: This paper found that countries with higher literacy rate, better institutions, higher per capita income, higher degree of openness to trade, and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro-economy.
