Alan Walters has suggested that the European Monetary System will prove dynamically unstable when capital controls are removed. The argument is analysed within a model that includes overlapping contracts. It is found that the short-run effects predicted by Walters only arise when the credibility...

We analyze a two-country zone facing a joint inflationary shock and responding with coordinated and uncoordinated monetary and fiscal policies. We show that the standard presumption that the absence of coordination results in an excessive exchange rate appreciation of the zone with respect to...

In many countries social security is a large fraction of the government budget. Why should this be so, given that at any moment in time the number of recipients of social security benefits is smaller than the number of contributors? More generally, what determines the size of social security? To...

This paper analyses economic integration between two economies; one central, with a large local market, and the other peripheral, with a small local market. Each economy has an imperfectly competitive manufacturing sector. Trade liberalization creates a strong incentive for the imperfectly...

Over the past century, the world economy has passed through a succession of phases characterized by very different levels of international capital flows. This paper asks what accounts for these dramatic shifts in the extent of capital movements across national borders. Three categories of...

This paper investigates the relation between the dynamics of inflation and exchange-rate regimes. It demonstrates that fixed exchange-rate regimes such as the international gold standard and the Bretton Woods gold-dollar standard appear to be associated with negligible persistence of inflation...

The paper analyzes the role of a multilateral payments union (PU) between East European countries (EEPU) as an intermediate solution in the process to full convertibility. After a description of the main functions of a PU, which is based on the historical model of the European Payments Union, it...

An optimum currency area is an economic unit composed of regions affected symmetrically by disturbances and between which labour 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...

This paper documents the effects of exchange rates and the external constraint during the interwar years. In the absence of international policy coordination, exchange rate depreciation is shown to have been a necessary precondition for the adoption of policies promoting recovery from the Great...

Exchange rate behavior is analyzed in the context of a stochastic rational expectations model in which there are random shocks to the price setting mechanism and in which the authorities choose to impose either nominal or real exchange rate bands. Results are compared to those that emerge from a...
