Kazakhstan and Germany have different development levels of the agricultural sectors. One of the explanations for this fact might be the different investment behavior of farmers in the two countries. We experimentally analyze whether the investment behavior of farmers is consistent with the...

We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices. Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

This paper explores the relationship between linguistic variation and individual attitudes toward risk and uncertainty. We propose an innovative marker that classifies languages according to the number of non-indicative moods in the grammatical contexts involving uncertainty. We find that...

We study a two-stage R&D project with an abandonment option. Two types of uncertainty influence the decision to start R&D. Demand uncertainty is modelled as a lottery between a proportional increase and decrease in demand. Technical uncertainty is modelled as a lottery between a decrease and...

Farm-level adaptation to changing economic environments is often slower than expected. Technological innovations, for instance, are frequently adopted at a later date than the net present value of investment suggests. This can be explained by a model of “investment under uncertainty,” which...

The papers of the dissertation focus on decision making under uncertainty of farmers in developed and developing countries and apply experimental approaches in order to investigate farmersʾ risk attitude and investment behavior. The first paper experimentally examines the investment and...

We document that an internal locus of control can be hindering in financial market situations, where short-term outcomes are determined by chance. The reason is that internally controlled individuals may tend to (over-)react to random outcomes. Our evidence is based on an experiment in which...
