This paper reports on a two-task principal-agent experiment in which only one task is contractible. The principal can either offer a piece-rate contract or a (voluntary) bonus to the agent. Bonus contracts strongly outperform piece rate contracts. Many principals reward high efforts on both...

This paper studies the effect of technology spillovers on the entry decision of a multinational enterprise into a foreign market. Two alternative entry modes for a foreign direct investment are considered: Greenfield investment versus acquisition. We find that with quantity competition a...

This work analyses how taxes determine the activities of multinational enterprises within the EU. Using disaggregated data, it is shown empirically, that different types of foreign direct investment react in different ways to alternative measures of the tax burden. It is shown theoretically,...

This dissertation is a collection of three independent research papers and three chapters with surveys introducing into the respective literature. The first paper analyses the effects of introducing Inequity Aversion in a Moral Hazard Problem, the second paper is about optimal delegation in...

We provide indirect empirical evidence of profit shifting behavior by multinational enterprises (MNEs) employing a panel study for the years 1995 to 2005, while controlling for unobservable fixed firm effects. We use a large micro database of European MNEs which includes detailed accounting and...

We provide indirect empirical evidence of profit shifting behavior by multinational enterprises. This issue is analyzed in an econometric panel study for the years 1995 to 2005 and additionally in a cross-section for 2004 using a large micro database of European subsidiaries of multinationals...

This paper studies the entry decision of a multinational enterprise into a foreign market. Two alternative entry modes for a foreign direct investment are considered: Greenfield investment versus acquisition. In contrast to existing approaches, the acquisition price and the profits under both...

Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

This paper surveys recent experimental and field evidence on the impact of concerns for fairness, reciprocity and altruism on economic decision making. It also reviews some new theoretical attempts to model the observed behavior.

We show experimentally that fairness concerns may have a decisive impact on both the actual and the optimal choice of contracts in a moral hazard context. Explicit incentive contracts that are optimal according to self-interest theory become inferior when some agents value fairness. Conversely,...
