Exchange Rate Dynamics in Anticipation of Time-Contingent Regime Switching : Modelling the Effects of a Possible Delay

The procedure of fixing a currently floating exchange rate at a given (and publicly announced) future date has a broad range of applications. Based on a (continuous-time) monetary exchange rate model with flexible prices, this paper analyzes exchange rate dynamics during the transition from floating to fixed rates in a situation in which market participants are uncertain about adherence to the fixing date and in which they take account of a possible delay in the regime switch. The closed-form solutions derived here allow us to quantify announcement effects as well as effects on the exchange rate variance caused by news that significantly changes the market's assessment of uncertainty
