Unions are an important indicator of various measures of firm performance in Anglo-Saxon countries. The same holds for the German analogue of workplace unionism's the works council. Using the IAB Establishment Panel I examine the impact of works councils and shop-floor participation on further...

Focusing on the compression of wage cuts, many empirical studies find a high degree of downward nominal wage rigidity (DNWR). However, the resulting macroeconomic effects seem to be surprisingly weak. This contradiction can be explained within an intertemporal framework in which DNWR not only...

Using panel data for Prussia during 1882 to 1910, we replicate Mehlum, Miguel, and Torvik's (2006) study on the causal effect of poverty on crime in 19th century Germany. In addition, our data set allows us to make several original contributions to the literature. We confirm the robust positive...

Using data spanning over four decades (1960-2000), this paper employs Engel's needsbased approach to analyzing household expenditure patterns to find evidence for the existence of a stable hierarchy of expenditure patterns at low levels of household income. Second, we investigate how rising...

The rapidly growing literature on the relationship between energy consumption and economic growth has not univocally identified the real causal relationship yet. We argue that bivariate models, which analyze the causality at the level of the total economy, are not appropriate - especially in...

Inter-firm competition has received much attention in the theoretical literature, but recent empirical work suggests that the growth rates of rival firms are uncorrelated, and that firm growth can be taken as an essentially independent process. We begin by investigating the correlations of the...

Despite lower incomes, the self-employed consistently report higher satisfaction with their jobs. But are self-employed individuals also happier, more satisfied with their lives as a whole? High job satisfaction might cause them to neglect other important domains of life, such that the...

How can economic theory explain the reasons why consumers adopt innovations? Using the example of innovations in washing machines two approaches are compared. The first focuses in the manner of household production theory on changes in constraints without specifying preferences, leading to the...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors, spanning the space of Engel curves. Once the common factors are estimated via approximate principal components, we identify them by imposing...
