Spite and cognitive skills in preschoolers

Other-regarding preferences in adults have been examined in depth in the literature. Research has shown that spiteful preferences play a crucial role in the development of human large-scale cooperation. However, there is little evidence of the factors explaining spiteful behavior in children. We investigate the relationship between children’s cognitive skills and spiteful behavior in a sample of 214 ...

Law and social capital: Evidence from the Code Napoleon in Germany

I test whether legal institutions crowd-in social cooperation in the long-run, using the introduction of the Code Napoleon in parts of 19th century Germany as a historical experiment. I find that the application of the Code Napoleon is associated with higher levels of trust and cooperation today. This finding is robust to an identification strategy that uses only individuals located around a discontinuity ...

Revisiting Rebound Effects from Material Resource Use. Indications for Germany Considering Social Heterogeneity

In contrast to the original investigation by William Stanley Jevons, compensations of energy savings due to improved energy efficiency are mostly analyzed by providing energy consumption or greenhouse gas emissions. In support of a sustainable resource management, this paper analyzes so-called rebound effects based on resource use. Material flows and associated expenditures by households allow for ...

Rating Agencies – An Experimental Analysis of Their Remuneration Model

Does it matter who pays for ratings? Yes, but not for the rating agencies’ behavior. These are the findings of our experiment where we analyze the effect of the remuneration model of rating agencies on their assessments as well as on investors’ and issuers’ behavior. First, we find that rating agencies’ assessments are comparable whether the agency is (partially) paid by issuers, investors or solely ...

The impact of psychological traits on performance in sequential tournaments: Evidence from a tennis field experiment

In order to analyze if heterogeneity in psychological traits affects individual performance in sequential tournaments, we conducted a tennis field experiment. In the experiment, we also varied the payment schemes (individual, team, competition) to control for moderating effects of different incentives. Team incentives, risk taking, and self-esteem reduced performance whereas a preference towards competition ...

Panel estimates of the wage penalty for maternal leave

The focus of this paper is the size of the wage penalty due to maternal leave incurred by working mothers in Germany. Existing estimates suggest large penalties with little rebound over time. We apply recent panel data methods designed to address problems of sample selectivity, unobserved heterogeneity and endogeneity to German Socio-Economic Panel (GSOEP) data. Heckman's classic treatment of ...

Demographic and economic factors influencing inclusion in the German sport system - a microanalysis of the years 1985 to 2005

Decreasing Sports Activity With Increasing Age? Findings From a 20-year Longitudinal and Cohort Sequence Analysis

According to cross-sectional studies in sport science literature, decreasing sports activity with increasing age is generally assumed. In this paper, the validity of this assumption is checked by applying more effective methods of analysis, such as longitudinal and cohort sequence analyses. With the help of 20 years' worth of data records,from the German Socio-Economic Panel, the development of ...

Testing Missing at Random Using Instrumental Variables

This article proposes a test for missing at random (MAR). The MAR assumption is shown to be testable given instrumental variables which are independent of response given potential outcomes. A nonparametric testing procedure based on integrated squared distance is proposed. The statistic?s asymptotic distribution under the MAR hypothesis is derived. In particular, our results can be applied to testing ...
