 First-generation models: inconsistent

macroeconomic policies and fixed exchange

 Second-generation models: multiple

equilibria and self-fulfilling attacks

 Third-generation models: interconnection

between exchange rate and financial fragility and financial institiutions

 Contagion

 Structural models  Panel data models (discrete-variable

techniques)

 Crisis definition

  • Exchange market pressure index
  • Conventional

 signaling methods  Contagion definition:

  • Interdependence, or;
  • Pure contagion

 Transmission channels: common shocks,

trade linkages, financial linkages, political linkages, macroeconomic similarities

 Panel data models, Eichengreen et al. (1996)

  • assumption of independently distributed

equation errors across countries introduce a substantial bias, Pesaran and Pick (2007).

 Duration analysis

  • Semi-parametric continuous models,
  • Semi-parametric discrete models,
  • Parametric models

 several robustness checks, running the models on two

different crisis episodes sets identified based on monthly and quarterly data

 probability of currency crisis rises with

undesired changes in job markets as well as macroeconomic fundamentals

 Estimation results for trade linkages were

constantly significant
