Interpreting interaction terms in linear and non-linear models: A cautionary tale
Drichoutis, Andreas - Volkswirtschaftliche Fakultät, … - 2011
Interaction terms are often misinterpreted in the empirical economics literature by assuming that the coefficient of interest represents unconditional marginal changes. I present the correct way to estimate conditional marginal changes in a series of non-linear models including (ordered)...

(Re)estimating marginal changes after “truncreg” and “tobit” in Stata
Drichoutis, Andreas - Volkswirtschaftliche Fakultät, … - 2011
In this note I show that a typo in Stata’s help file may have contributed in wrongly estimating marginal changes after truncated and censored regression models. This has significant implications for empirical practice and results from published studies may need to be reconsidered.

Power of significance test of dummies in Simar-Wilson two-stage efficiency analysis model
Zelenyuk, Valentin - Volkswirtschaftliche Fakultät, … - 2005
In this note we investigate the power of significance test for dummy-variables in the context of Simar and Wilson (2003) two-stage efficiency analysis model.

A non-parametric analysis of the efficiency of the top European football clubs
Halkos, George; Tzeremes, Nickolaos - Volkswirtschaftliche Fakultät, … - 2011
This paper analyses how European football clubs’ current value and debt levels influence their performance. The Simar and Wilson (J Econometrics, 136: 31–64, 2007) procedure is used to bootstrap the data envelopment analysis DEA scores in order to establish the influence of football clubs’...

Moments of the generalized hyperbolic distribution
Scott, David J; Würtz, Diethelm; Dong, Christine; … - Volkswirtschaftliche Fakultät, … - 2009
In this paper we demonstrate a recursive method for obtaining the moments of the generalized hyperbolic distribution …. The method is readily programmable for numerical evaluation of moments. For low order moments we also give an alternative … derivation of the moments of the generalized hyperbolic distribution. The expressions given for these moments may be used to …
