This paper proposes a tractable and realistic nonlinear model of exchange rate dynamics, and argues that its predictions are consistent with available empirical evidence on exchange rate and interest differential behavior in real-life target zones. In our model, the exchange rate fluctuates...

We examine the expected survival time of a unilateral exchange rate target zone, when constraints on monetary policy prevent the central bank from exclusively focusing on defending the target zone. Generally, the width of the target zone has a negligible effect on the expected survival time, and...
