Robust Lessons about Practical Early Warning Systems

  • Beckmann, Daniela
  • Menkhoff, Lukas
  • Sawischlewski, Katja

Early warning systems (EWSs) are subject to restrictions that apply to exchange rates in general: fundamentals matter but their influence is small and unstable. Despite this limitation four major lessons emerge: First, EWSs have robust forecasting power and thus help policy-makers to prevent crises. Second, policy-makers must decide about some EWSs elements, such as the sensitivity of the forecasts. Third, EWSs performance is increased by taking a logit model, shorter samples and a regional approach. Fourth, the finding of contagion may motivate policy to shield its economy against inefficient international financial markets.
