"We investigate wage effects of deviations from peer group body mass index (BMI) to evaluate the influence of social norms on wages. Our approach allows for disentangling the influence of the social norm from any (anticipated) productivity effects associated with deviations from a clinically...

We investigate one possible explanation for observed rates of corrupt behavior namely that individual decision makers who frequently engage in illegal actions may underestimate the overall probability of being caught. This might in particular be true for petty corruption where small amounts of...

We investigate the impact of trust in authorities on tax compliance within a controlled laboratory setting. Embedded in two hypothetical tax systems with high and low power of authorities respectively, we gradually increase trust in authorities in form of tax knowledge about public expenditures...

We econometrically evaluate the performance effects of a six month e-learning programme in a large retail chain with monthly data on sales revenue, for four years using panel regressions. Participants in early cohorts show positive performance effects during training periods that depreciate...

This paper investigates the efficiency of the matching process between job seekers and vacancy posting firms in West-Germany, using variation across labor market regions and across time. The results of a stochastic frontier analysis shed new light on extent and regional differences of search...

Although an inverse relationship between sickness absence and unemployment has been documented in a number of studies using either quarterly or annual data from different countries with varying institutional frameworks, it is not yet clear whether this empirical regularity is due to changes in...

Starting in January 2003, Germany implemented the first two so-called Hartz reforms, followed by the third and fourth packages of Hartz reforms in January 2004 and January 2005, respectively. The aim of these reforms was to accelerate labor market flows and reduce unemployment duration. Without...

By applying a stochastic production frontier approach to the matching process of unemployed and vacancies, this paper provides novel detailed insights into the process of job creation. For different labor markets as defined by occupation and region, the methodology produces estimates of the...

This paper makes two contributions to the empirical matching literature. First, a recent study by Anderson and Burgess (2000) testing for endogenous competition among job seekers in a matching framework, is replicated with a richer and more accurate data set for Germany. Their results are...
