In this paper we introduce a new test of the null hypothesis of nocointegration between a pair of time series. For a very simple generating model, ourtest compares favourably with the Engle-Granger/Dickey-Fuller test and the Johansentrace test. Indeed, shortcomings of the former motivated the...

Stationarity of hedge ratios can be viewed as a first step for portfolio hedging since it represents that the sensitivity of spot and futures returns follow a process whose main characteristics do not depend on time. However, we provide evidence that the hedge ratios of the main European stock...

This paper provides the empirical framework to analyse the nature of currency crises by extending earlier work of Jeanne and Masson (2000) who suggest that a currency crisis model with multiple equilibria can be estimated using Markov regime switching (MRS) models. However, Jeanne and Masson...
