Markov Switching Regimes in a Monetary Exchange Rate Model*
نویسنده
چکیده
This paper extends the real interest differential (RID) model of Frankel (1979) by introducing Markov regime switches for three exchange rates over the years 1973 2000. Evidence of a non-linear relationship between exchange rates and underlying fundamentals is provided. One of the regimes represents exactly the RID case. Decisive fundamentals in determining regimes turn out to be mainly interest rates. The established relationship is shown to be stable in several respects: regimes are highly persistent, provide a much better description of the data than alternatives and are robust towards several modifications. JEL classification: F31

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...
