Intervention Policy and Mean Reversion in Exchange Rate Target Zones: The Swedish Case.

The intervention policy of the Swedish central bank is studied using daily intervention data for the late 1980s. In contrast to the first generation of target zone models, the authors find that the interventions occur all over the exchange rate band and almost every day. Based on this evidence, they estimate an exchange rate target zone model with intramarginal interventions. The results go a long way towards explaining the well-established hump-shaped exchange rate distribution and lack of nonlinearities.
