On the Channels of Pro-Social Behavior Evidence from a natural field experiment

We conduct a natural field experiment on direct and indirect transfer mechanisms for small donations. Charitable contributions are significantly higher if made indirectly, i.e. if they are tied to the purchase of a good sold at a premium, than if they are made directly. Donations are signficantly higher under both transfer mechanisms if people are given a suggested reference donatioTied versus untied transfers, charitable donations, charity, willingness to give, pro social behavior

Inefficient but Effective? A field experiment on the effectiveness of direct and indirect transfer mechanisms

We conduct a field experiment on direct and indirect transfer mechanisms. It shows that people are willing to donate significantly more if the donation is indirect, i.e., it is tied to the purchase of a good with a price premium, rather than made directly. This points to an efficiency–effectiveness trade–off: even though indirect donations are less efficient than direct donations, they are more effective in mobilizing resources. Our findings hold for ‘Fair Trade’ coffee as well as for ‘normal’ coffee. However, the strength of the efficiency–effectiveness trade–off is higher in the case of ‘Fair Trade’.Tied transfers, donations, charity, efficiency versus effectiveness, ‘fair trade’

Endogenous Environmental Policy when Pollution is Transboundary

We analyze the formation of environmental policy to regulate transboundary pollution if governments are self-interested. In a common agency framework, we portray the environmental policy calculus of two political supportmaximizing governments that are in a situation of strategic interaction with respect to their environmental policies, but too small to affect world market prices. We show how governments systematically deviate from socially optimal environmental policies. Taxes may be too high if environmental interests and pollution-intensity of production are very strong; under different constellations they may be too low. Governments may actually subsidize the production of a polluting good. Politically motivated environmental policy thus may be more harmful to the environment as compared to the benevolent dictators’ solution. In other cases it may enhance environmental quality and welfare beyond what a benevolent government would achieve.Political economy, environmental policy, transboundary pollution, common agency, strategic interaction

What does it take to be a star? The role of performance and the media for German soccer players

We test existing superstar theories for the German soccer league. We use various measures for individual players’ performance and media presence to analyze whether performance and popularity can explain salaries and superstars in soccer. Moreover, we argue that quantile regression technique should be applied to analyze superstar phenomena instead of OLS used hitherto.Superstars, soccer, quantile regressions, Rosen, Adler

What and how long does it take to get tenure? The Case of Economics and Business Administration in Austria, Germany and Switzerland?

This paper investigates the determinants of tenure decisions in Germany, Austria and the German-speaking part of Switzerland for professorships in economics, business administration and related fields. Our data set comprises candidates who were awarded tenure as well as those who were eligible but were not tenured. We show that business candidates have a higher probability of being tenured than economists. Youth, marital status, and publications matter; gender and children do not. The market for first appointments in economics relies much more on publication performance than the market for business administration.Habilitation, tenure, academic labor market

Zeitschriftenrankings für die Wirtschaftswissenschaften Konstruktion eines umfassenden Metaindexes

This paper constructs several meta-indexes of journal rankings from existing journal rankings which all have limited coverage. It is applicable both for researchers in the field of economics and business administration (including their respective subfields) and includes also journals which are published in German. We discuss the relative merits of meta-indexes based on peer assessment and on citations.Zeitschriftenranking, Evaluation von Forschung, Meta-Index

Functional characterization of a class III acid endochitinase from the traps of the carnivorous pitcher plant genus, Nepenthes

Carnivory in plants is an adaptation strategy to nutrient-poor environments and soils. Carnivorous plants obtain some additional mineral nutrients by trapping and digesting prey; the genus Nepenthes is helped by its specialized pitcher traps. To make the nutrients available, the caught prey needs to be digested, a process that requires the concerted activity of several hydrolytic enzymes. To identify and investigate the various enzymes involved in this process, fluid from Nepenthes traps has been analysed in detail. In this study, a novel type of Nepenthes endochitinase was identified in the digestion fluid of closed pitchers. The encoding endochitinase genes have been cloned from eight different Nepenthes species. Among these, the deduced amino acid sequence similarity was at least 94.9%. The corresponding cDNA from N. rafflesiana was heterologously expressed, and the purified protein, NrChit1, was biochemically characterized. The enzyme, classified as a class III acid endochitinase belonging to family 18 of the glycoside hydrolases, is secreted into the pitcher fluid very probably due to the presence of an N-terminal signal peptide. Transcriptome analyses using real-time PCR indicated that the presence of prey in the pitcher up-regulates the endochitinase gene not only in the glands, which are responsible for enzyme secretion, but at an even higher level, in the glands’ surrounding tissue. These results suggest that in the pitchers’ tissues, the endochitinase as well as other proteins from the pitcher fluid might fulfil a different, primary function as pathogenesis-related proteins
