This paper studies the aggregate substitution and expansion effects triggered by changes in input prices, in a context where firms supply a homogenous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

For a time-continuous discrete-state Markov process as model for rating transitions, we study the time-stationarity by means of a likelihood ratio test. For multiple Markov process data from a multiplicative intensity model, maximum likelihood parameter estimates can be represented as martingale...

A basic assumption of the gravity equation of international trade is that increasing trade costs lower exports. Butintuition and theory imply that a high export volume lowers bilateral trade costs as well, because a fixed cost intensivetrade sector probably bears lower average costs with more...

Policymakers in developing countries have increasingly pinned their hopes on bilateral investment treaties (BITs) in order to improve their chances in the worldwide competition for foreign direct investment (FDI). However, the effectiveness of BITs in inducing higher FDI inflows is still open to...

This paper analyses the impact of aid flows on governance. Using an instrumental variable approach and a large country sample, we find that aid has a negative rather than a positive influence on governance. This outcome is robust to various model specifications.

Labor and product market regulations affect the unemployment rate of a country without doubt. Econometricians, however, have yet to establish an unequivocal significance of this impact. Model mis-specification, one of the main underlying problems, is overcome by adopting a Bayesian Model...

In this paper we question the consensus of using a binary crisis definition for empirical crisis models. We believe that the most severe shortcomings of the crisis models today are in the crisis definition rather than the explanatory variables. We present a crisis model that is specified for a...

In diesem Beitrag wird analysiert, ob Wechselkursprognosen Anhaltspunkte dafür liefern, dass Prognostiker ein so genanntes Herdenverhalten zeigen. Auf der Basis unterschiedlicher theoretischer Modellansätze wird skizziert, warum Prognostiker einen Anreiz haben könnten, einem Herdentrieb zu...

This paper estimates the impact of training incidence and duration on employment transitions accounting for the endogeneity of program participation and duration. We specify a very flexible bivariate random effects probit model for employment and training participation and we use Bayesian Markov...
