International crises,instability periods and contagion: the case of the ERM

In this article we propose a two step procedure for modeling the propagation of financial shocks. The first step consists in the estimation, by means of SWARCH models, of the conditional probability of being in a period of high volatility, while in the second step such indicators are included in a structural simultaneous equations models for interdependences among different countries. The results show that episodes of financial crisis effectively happened during periods of high volatility and that such measures of instability are important in explaining the propagation of devaluation expectations between six European Countries during the ERM period.
