The empirical evidence supports the significance of political instability...

Loss of confidence is interpreted as an increase in the ambiguity experienced by investors who maximize Choquet Expected Utility. Currency crises are modelled to resemble bankruns. Using countries having fragile financial systems, a model of twin crises is obtained. An exogenous interim loss of...

I construct a micro-model to show that a currency crisis can spread from one country to another even when these countries are unrelated in terms of economic fundamentals and there is no capital linkage across countries through a common lender or an interbank market. The key to explaining...

This paper studies the implications of the presence of a large speculator like George Soros during a contagious currency crisis. The model proposes a new contagion channel and shows how a currency crisis can spread from one country to another even when these countries are totally unrelated in...

Early warning systems (EWSs) are subject to restrictions that apply to exchange rates in general: fundamentals matter but their influence is small and unstable. Keeping this in mind, five lessons emerge : First, EWSs have robust forecasting power and thus help policy-makers to prevent crises....
