<Para ID="Par1">This paper proposes a measure of exchange market pressure for countries operating in hard peg regimes, such as currency unions, currency boards or full dollarization. We use a general model of currency crisis to derive a sustainability index based upon the relationship between the shadow...</para>

Currency and financial turmoils in international capital markets have been the focus of an extensive theoretical research which started around 30 years ago. This paper provides a synthetic overview of this theoretical modeling. We analyze the basic analytical framework corresponding to the...

This paper analyzes strategic interactions and contagion effects in the peripheral countries of a monetary union. Using game theory and cost-benefit analysis, the paper determines the set of equilibrium solutions under which country-specific shocks are transmitted to other member countries...

This paper investigates currency and financial crises in an optimizing general equilibrium model. It is shown that a rise in current and expected future budget deficits generates a real exchange rate appreciation and a decumulation of external assets, leading up to a currency crisis when foreign...

This paper investigates currency crises in an optimizing general equilibrium model with overlapping generations. It is shown that a rise in government budget deficits financed by future taxes generates a decumulation of external assets, leading up to a speculative attack and forcing the monetary...

This paper aims to propose a new measure of exchange market pressure for countries operating in hard peg regimes, such as currency unions, currency boards or full dollarization. We use a general model of currency crisis to derive a sustainability index based upon the relationship between the...

This book deals with the genesis and dynamics of exchange rate crises in fixed or managed exchange rate systems. It provides a comprehensive treatment of the existing theories of exchange rate crises and of financial market runs. It aims to provide a survey of both the theoretical literature on...
