Once one recognizes that governments borrow international reserves and exercise other policy options to defend fixed exchange rates during currency crises, the question arises: What factors determine a government's decision to abandon a currency peg or hang on? In a setting of purposeful action...

This paper surveys the performance of international capital markets and the literature on measuring international capital mobility. Three main functions of a globally integrated and efficient world capital market provide focal points for the analysis. First, asset-price arbitrage ensures that...

What idiosyncratic consumption risks can countries trade away on international asset markets? This paper develops an empirical methodology for answering the question. The tests are based on the proposition that in an integrated world asset market with representative national agents, the ex post...

This paper presents a simple diagrammatic analysis of an open economy's external adjustment process under habit-forming individual preferences. The exposition focuses on the consumption side and aims to make transparent the linkage among wealth, past consumption experience, and current...

This paper develops a dynamic continuous-time model in which international risk sharing can yield substantial welfare gains through its positive effect on expected consumption growth. The mechanism linking global diversification to growth is an attendant world portfolio shift from safe, but...

This paper studies the mechanisms of international payments adjustment at work under the Bretton Woods system of fixed exchange rates, 1945 to 1971. I argue that two market failures, imperfect international capital mobility and imperfect wage-price flexibility, are central to understanding the...

This paper studies the merits of policy rules with escape clauses, analyzing as an example fixed exchange-rate systems that allow member countries the freedom to realign in periods of stress. Motivating this example is the debate within the European Monetary System over how quickly to move from...

This paper develops simple geometric methods for analyzing dynamic behavior in models with intertemporally dependent consumer tastes. Since the preferences studied do not assume time-additivity, they allow the marginal utility of consumption on a given date to vary with consumption on other...

This paper shows that the optimal extraction of seigniorage implies a strong tendency for inflation to fall over time toward its socially optimal level. The point is made using a multi-period model in which (i) the government can finance deficits through bond issue or money creation, (ii)...

Since the September 1985 Plaza Hotel announcement by the Group of Five industrial countries, a substantial realignment of exchange rates has been achieved. At the same time, foreign exchange market intervention, much of it concerted and much of it sterilized, has been undertaken on a scale not...
