We empirically study personal norms of sustainability, conceptualized according to the norm-activation theory and operationalized under the notion of strong ecological-economic sustainability, for commercial cattle farmers in semi-arid rangelands of Namibia, a system that is subject to extensive...

We study risk preferences and their determinants for commercial cattle farmers in Namibia who are subject to high precipitation risk that is heterogeneous across farms. We use data on risk preferences from questionnaire and field experiments, simulated data for on-farm precipitation risk and...

This paper takes a labor supply perspective (neoclassical labor supply, job search) to explain the lower employment rates of older workers and women. The basic rationale is that workers choose non-employed if their reservation wages are larger than the offered wages. Whereas the offered wages...

This study provides first comprehensive analyses of foreign-controlled enterprises in the German service sector based on new micro data from official statistics. Various performance measures were examined by comparing unconditional and conditional means and quantile regression techniques were...

Since the late 1990s, the European higher education system has had to face deep structural changes. With the public authorities seeking to create an environment of quasi-markets in the higher education sector, the increased competition induced by recent reforms has pushed all publicly financed...

A large and growing number of micro-econometric studies show that exporting firms are more productive than firms that sell their products on the home market only. This so-called exporter productivity premium qualifies as a stylized fact. Only recently researchers started to look at the role of...

Scientific literature postulates that nanotechnology is to be considered as general purpose technology (GPT), characterized by pervasiveness, high technological dynamism and the inducement of innovations within a variety of applications. We set out to not only further systematize existing...

In recent years demographic aging and its consequences have been recognized and discussed on macroeconomic levels, such as health care system, infrastructure, housing and labour market. However, the consequences are not only present on the macroeconomic level but also affect microeconomic issues...

We conduct an experiment to uncover the reasons behind the typically large behavioral variation and low explanatory power of Nash equilibrium observed in Tullock contests. In our standard contest treatment, only 7% of choices are consistent with Nash equilibrium which is in line with the...

A stylized fact from the emerging literature on the micro-econometrics of international trade and a central implication of the heterogeneous firm models from the new new trade theory is that exporters are more productive than non-exporters. However, many firms from the lower end of the...
