In der ökonomischen Zufriedenheitsforschung wird ein negativer Effekt von Kindern auf die elterliche Zufriedenheit ermittelt. Dazu werden oftmals Probitmodelle geschätzt. In diesem Papier wird nun ein fixed effects Modell benutzt. Mittels Daten des Sozioökonomischen Panels (SOEP) werden...

In empirical studies it often happens that some variables for some units are far away from the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses – conclusions based on a sample with and without these...

We clarify the definition and interpretation of “sustainability economics” (Baumgärtner and Quaas 2010) in response to recent comments by van den Bergh (2010), Bartelmus (2010) and others. For that sake, we distinguish between general and specific definitions of sustainability and...

We use a long panel data set for four entry cohorts into an internal labor market to analyze 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 that longer training measures are...

This paper analyzes the productivity development in the German public theater sector for the seasons 1991/1992-2005/2006. Using a stochastic distance frontier approach that allows to decompose total factor productivity change into different sources we examine (a) whether Baumol’s cost-disease...

We investigate the elasticity of preferences for moral ignorance with respect to monetary incentives and social norm information. We propose a model where uncertainty differentially decreases the moral costs of unethical behavior, and benchmark the demand curve for moral ignorance against a...

This paper presents an analysis of the recent developments of average market power in Europe by using a broad firm-level database for EU member states. To indicate competitive pressure at the firm-level, markups are estimated following De Loecker (2011), and De Loecker and Warzynski (2012). The...

This paper investigates the influence of industrial relations on firm wage premia in Germany. OLS regressions for the firm effects from a two-way fixed effects decomposition of workers' wages by Card, Heining, and Kline (2013) document that average premia are larger in firms bound by collective...

This paper develops a bivariate fractional probit model for fractional response variables, i.e., variables bounded between zero and one. The model can be applied when there are two seemingly unrelated fractional response variables. Since the model relies on a quite strong bivariate normality...
