This article studies how discussion issues emerge and argumentative discussions are initiated. Studying how discussions are initiated enables us to understand who is a legitimate instigator of a discussion issue and to what extent the freedom rule of argumentation is granted in a given context....

The standard gravity model of aggregate migration erroneously assumes homogeneity, quasi-symmetry, and (log) linearity. As a result, estimation of the model using, say, the convenient OLS estimator is plagued by omitted-variables and misspecification biases. This paper, therefore, presents...

This paper applies the Hafner and Herwartz (2006) (hereafter HH) approach to the analysis of multivariate GARCH models using volatility impulse response analysis. The data set features ten years of daily returns series for the New York Stock Exchange Index and the FTSE 100 index from the London...

This paper analyzes enhanced cooperation agreements in corporate taxation in a three country tax competition model where countries differ in size. We characterize equilibrium tax rates and the optimal tax responses due to the formation of an enhanced cooperation agreement. Conditions for...

This paper analytically derives the conditions under which the slope of the tax reaction function is negative in a classical tax competition model. If countries maximize welfare, we show that a negative slope (reflecting strategic substitutability) occurs under relatively mild conditions....
