We use a simple model of international lending to show that an emerging market borrower who might default can be shut out of international capital markets without warning. A modest haircut on obligations, for example, can shut down lending

Traditionally the choice of exchange rate regime has been seen as a second-best policy choice, which can be directed toward mitigating the distortionary effects of price or information rigidities. In this paradigm the optimal degree of exchange rate flexibility is found to depend of the source...

In this paper we develop and test a model of a utility maximizing representative agent operating in the Belgium-Luxembourg two-tier foreign exchange market. Our tests examine and fail to reject a risk neutral representative agent utility function. When we combine a risk neutral utility function...

The literature on two-tier foreign exchange markets has concentrated on relating various shocks to the spread between the exchange rates relevant to the two tiers of the exchange market. In some earlier work we found that none of the typical predictions of theory held up empirically as BLEU...

The paper shows that changing market beliefs about currency risk can generate a self-fulfilling speculative attack on a fixed exchange rate. The attack does not require a later change in policies to make it profitable. This is illustrated by introducing an endogenous risk premium into a...

After the speculative attacks on government-controlled exchange rates in Europe and in Mexico, economists began to develop models of currency crises with multiple solutions. In these models, a currency crisis occurs when the economy suddenly jumps from one solution to another. This paper...

We develop a simple framework for studying the joint distribution of banking and currency crises triggered by real shocks. Our framework illustrates the fact that bank and currency collapses are related but they are not the same thing. Studying currency and bank collapses either in isolation or...

Why do countries hold so much international reserves? Global reserve holdings (excluding gold) were equivalent to 17 weeks of imports at the end of 1999. That is almost double what they were at the end of 1960 and about 20 percent higher than they were at the start of the 1990s. In this paper we...
