Could a less conservative central bank - one that faces a more severe time inconsistency problem - be less likely to succumb to an attack on a currency peg? Traditional currency-crisis models provide a firm answer: No. We argue that the answer stems from these models' narrow focus on how a...

Confronted with a speculative attack on its currency peg, an authority weighs the short-term benefit of giving in and fine tuning the economy against the long-term benefit of credibility-enhancing resistance. In turn, speculators with heterogeneous beliefs face strategic uncertainty that peaks...

Financial markets are to a very large extent influenced by the advent of information. Such disclosures, however, do not only contain information about fundamentals underlying the markets, but they also serve as a focal point for the beliefs of market participants. This dual role of information...

When Choi has rediscovered that Adam Smith had long solved the interest rate mystery, this paper extends the rediscovering to work out some extreme interest rate, like the very high, the very low and even the negative one. This paper also makes interest rate theory international, and corrects...

We propose a model in which sticky expectations concerning shortterm interest rates generate joint predictability patterns in bond and currency markets. Using our calibrated model, we quantify the effect of this channel and find that it largely explains why short rates and yield spreads predict...

This paper re-examines the empirical performance of the portfolio balance approach to currency returns. It considers the implications of two alternative specifications of preferences: one based on expected utility theory and the other on prospect theory. It also uses survey data to estimate...

An event study is used to assess the views of Keynes and Friedman on speculation. Speculative extremes are ranked by intensity of sentiment and weight of speculative activity. A unique dataset of risk-reversal skew on option prices is used to measure the intensity of speculative sentiment; the...

Abstracting from self-protection and self-insurance e ects of export produc-tion choices, exporting rms usually have access to a number of risk sharingmarkets that have an efficient risk management role. Two of the most strikingresults achieved from the existence of risk sharing markets are the...

We explore possible effects of a Tobin tax on exchange rate dynamics in a heterogeneous agent model. To assess the impact of the Tobin tax in this framework, we extend the model of De Grauwe and Grimaldi (2006) by including transaction costs and perform numerical simulations. Motivated by the...

We assume that the variations of the exchange rate depend on the current net demand of the base currency as a consequence of market making, and that the current net demand of the base currency depends on current and past variations of the exchange rate as a consequence of how future price...
