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

This paper analyses the effects of discretionary fiscal policy by presenting new empiricalevidence for Germany within a structural vector autoregression (SVAR) framework. FollowingBlanchard and Perotti (2002), the SVAR model is identified by applying institutionalinformation. We find no...

This paper analyzes and quantifies the idea of model risk in the environment of internal modelbuilding. We define various types of model risk including estimation risk, model risk in distributionand model risk in functional form. By the quantification of these concepts we analyzethe impact of...

We find a U-shaped relation between happiness and religiosity in cross-country panel dataafter controlling for income levels. At a given level of income, the same level of happinesscan be reached with high and low levels of religiosity, but not with intermediate levels. A risein income causes an...

The output multiplier turns negative before a deficit spending program expires.We show the generality of this unpleasant finding for the standard real business cyclemodel. We then calibrate an extended model for the US and demonstrate how fiscalstimulus slows down economic recovery from...

We present a stochastic version of the single-level, multi-product dynamic lotsizingproblem subject to a capacity constraint. A production schedule has tobe determined for random demand so that expected costs are minimized and aconstraint based on a new backlog-oriented Sigma-service-level...

This study validates a survey-based measure of general risk attitude by an incentivecompatible experiment among more than 900 participants in rural Thailand. The surveymeasure of self-assessed risk attitude provides a useful approximation of the experimentallyderived risk attitude. This holds...

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...

Ökonomische Experimente sind eine bislang selten verwendete Forschungsmethodeim Bereich der agrarpolitischen Analyse. Dieser Beitrag erörtert die Grundlagenvon Experimenten, vergleicht sie mit anderen Forschungsmethoden und zeigt ein möglichesAnwendungsgebiet für die Agrarpolitikanalyse auf...

We investigate to what extent convergence in production levels per worker has beenachieved in Germany since unification. To this end, we model the distributionof GDP per employee across German districts using two-component normal mixtures.While in the first year after unification, the two...
