Slow adjustment of real exchange rate towards equilibrium in linear models has long puzzled researchers, stimulating the adoption of nonlinear models. The exponential smooth transition model has been particularly successful, providing faster adjustment speeds. This paper discusses some of its...

Rogoff suggested in 1996 that the dollar-yen real exchange rate represented a 'canonical' case of a trend in the equilibrium real exchange rate. The implied speed of adjustment of the dollar-yen real exchange rate is found to be substantially faster, with half-life shocks of less than 2 years,...

Two different approaches intend to resolve the 'puzzling' slow convergence to purchasing power parity (PPP) reported in the literature [see Rogoff (1996), Journal of Economic Literature, Vol. 34.] On the one hand, there are models that consider a non-linear adjustment of real exchange rate to...
