Recently, Taylor (2002) concludes that long run PPP held over the 20th century for a set of 19 long term real exchange rates. We argue that this conclusion is quite sensitive to the use of sub-optimal lag selection in unit root tests. Using superior lag selection methods, we find that long run...

Early research on the Taylor rule typically divided the data exogenously into pre-Volcker and Volcker-Greenspan subsamples. We contribute to the recent trend of endogenizing changes in monetary policy by estimating a real-time forward-looking Taylor rule with endogenous Markov switching...
