This paper studies the survival of fixed exchange rate regimes. The probability of an exit from a fixed exchange rate regime depends on the time spent within this regime. In such a context durations models are appropriate, in particular because of the possible non-monotonic pattern of duration dependence. Non-parametric estimates show that the pattern of duration dependence exhibits non-monotonic behaviour and that it differs across types of economies. This behaviour persists when we control for time-varying covariates in a proportional hazard specification. We conclude that how long a regime has lasted will affect the probability that it will end, in a non-monotonic fashion.
