Recent empirical research by Mark Taylor and co-authors has found evidence of hybrid dynamics for the real exchange rate. While there is a random walk near equilibrium, for real exchange rates some distance from equilibrium there is mean-reversion which increases with the degree of misalignment....

In this paper we show how trading rules can generate excess volatility in the exchange rate through repeated entry and exit of currency bears and bulls. This is something of a caricature: but it allows us to show that offcial action can have self-fulfilling effects as market composition shifts...

In this paper we show how trading rules can generate excess volatility in the exchange rate through repeated entry and exit of currency "bears" and "bulls". This is something of a caricature: but it allows us to show that official action can have self-ful.lling e¤ects as market composition...
