We consider a recently proposed class of nonlinear time series models and focus mainly onmisspecification testing for models of such type. Following the modeling cycle for nonlineartime series models of specification, estimation and evaluation we first treat how to choosean adequate transition...

In ESTAR models it is usually dfficult to determine parameter estimates, as it can be observedin the literature. We show that the phenomena of getting strongly biased estimators is aconsequence of the so-called identication problem, the problem of properly distinguishing thetransition function...

How is it possible that exchange rates move in the long run towards fundamentals, whileprofessionals form consistently irrational exchange rate expectations? We look at this puzzle from adifferent perspective by analyzing investor sentiment in the US-dollar market. First, long-horizonregressions...

Early warning systems (EWSs) are subject to restrictions that apply to exchangerates in general: fundamentals matter but their influence is small and unstable. Despitethis limitation four major lessons emerge: First, EWSs have robust forecastingpower and thus help policy-makers to prevent...

This paper extends earlier studies on exchange rate expectations' formation by using newdata and adding information about forecasters' reliance on fundamental analysis for the firsttime. We replicate the conventional result of non rational expectations. Moreover, biases inexpectations are...

We study the relationship between foreign exchange trading activity and volatility on theUSD/EUR foreign exchange market on the basis of a unique data set around the events of09/11/2001. We find that volatility and bid-ask spreads are by far larger at that time, but theshock is not persistent....

This paper analyzes the behaviour and motivation of fund managers in foreign exchangemarkets reflected in questionnaire evidence. We find that fund managers andFX dealers differ significantly. Fund managers rely more on fundamentals, basicallydue to their longer forecasting horizons, and reject...
