Option prices seem to behave in ways inconsistent with the Black-Scholes model. Implied volatility varies with the strike price in a parabolic shape that is often called the volatility 'smile.' My objective in this paper is to identify implied probability distributions that might explain this...

Using panel data of 192 countries from 1970 through 1999, and 195 currency crisis episodes, this study examines the effect of membership in a currency union on the probability of experiencing a currency crisis. Both parametric and non-parametric estimates suggest that membership in a currency...

A traditional OCA criterion holds that the more symmetric the shock exposure of countries, the more suited they are for currency union. According to Frankel and Rose (1998, 2002), growing correlation of the ex post income fluctuations of members also can provide endogenous justification for...

We develop a simple model that highlights the costs and benefits of fixed exchange rates as they relate to trade, and show that negative export-price shocks reduce fiscal revenue and increase the likelihood of an expected currency devaluation. Using a new high-frequency data set on...

This paper discusses whether the integration of international financial markets affects business cycle fluctuations. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock....

If there is exchange market pressure (EMP), monetary authorities can use the interest rate and official interventions to offset this depreciation tendency, or they can let the exchange rate change. We introduce a new approach to derive how these three variables should be combined to measure EMP....
