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...

Determining good parameter estimates in ESTAR models is known to be difficult. We showthat the phenomena of getting strongly biased estimators is a consequence of the so-calledidentication problem, the problem of properly distinguishing the transition function in relationto extreme parameter...

We examine the asymptotic behavior of unit root tests against nonlinear alternativesof the exponential smooth transition type if the data is erroneously nonlinearly transformed...

While it is widely agreed that Purchasing Power Parity (PPP) holds as a long-runconcept the specific dynamic driving the process is largely build upon a priori economicbelief rather than a thorough statistical modeling procedure. The two prevailing timeseries models, i.e. the exponential smooth...

This paper makes three contributions to our understanding of the price discovery process in currencymarkets. First, it provides evidence that this process cannot be the familiar one based on adverse selectionand customer spreads, since such spreads are inversely related to a trade’s likely...

Price comparison services are being used by more and more internet users worldwide tocompare prices of (online-)suppliers. The characteristics of price comparison services differinternationally. Not only are they different in the reference to their scope of work. Also with regard tothe technical...

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....

The rational prodigality argument, which often serves to justify social security,is considered in a second-best tax framework with endogenous labor supply. Rationalprodigality renders the familiar policies time inconsistent. We analyze time consistentpolicies and show that a wage tax suffices to...

We use a long panel data set for four entry cohorts into an internal labor market toanalyze the effect of age on the probability to participate in different training measures.We find that training participation probabilities are inverted u-shaped with age and thatlonger training measures are...

The use of technical analysis by financial market professionals is not well understood. Thispaper thus analyzes survey evidence from 692 fund managers in five countries, the vast majorityof whom rely on technical analysis. At a forecasting horizon of weeks, technical analysis isthe most...
