To that end, we make use of Taylor’s (1980) price trend model that, instead of focusing on the mean reverting behaviour of exchange rates measured over a long horizon, concentrates on the shortterm pattern of the price trend. Employing a maximum likelihood method and a genetic algorithm to estimate the model parameters, in 39 of the 95 cases considered we find evidence in favour of the presence of trends, the trends being more frequent in intermediate exchange-rate regimes.engjournal articlehttps://doi.org/10.1080/13504851.2011.587757open accessC53F31G14Exchange ratesPrice trend modelGenetic algorithms.Econometría (Economía)Economía internacionalFinanzas5302 Econometría5310 Economía Internacional
