We present controlled experimental evidence on how corruption affects the private provision of public goods. Subjects in our experiment donate to non-profit associations. The associations provide local public goods that benefit all subjects. We compare average contributions between two...

This paper studies public goods provision in an experiment in which contributors repeatedly interact with rent-extracting administrators. Our main result is that the presence of an administrator reduces contributions but only because rent extraction lowers the MPCR. Analysing the dynamic...

This paper provides a first approach to assess gas market interaction on a network with nonconvex flow models. In the simplest possible setup that adequately reflects gas transport and market interaction, we elaborate on the relation of the solution of a simultaneous competitive gas market game,...

While single-level Nash equilibrium problems are quite well understood nowadays, less is known about multi-leader multi-follower games. However, these have important applications, e.g., in the analysis of electricity and gas markets, where often a limited number of firms interacts on various...

In this data documentation, we provide detailed information on the data that is used in order to calibrate the GATE model. Since we are looking at the hypothetical German electricity market in 2035 and the resulting investment incentives, we have to select all exogenous parameters based on...

In this paper we propose an equilibrium model in order to analyze the impact of electricity market design on generation and transmission expansion in liberalized electricity markets. In a multi-level structure, our framework takes into account that generation investment and operation is decided...

We conduct multi-person one-shot ultimatum games that reflect important aspects of collective bargaining. In all treatments a proposer has to divide a pie among herself and two groups of three recipients each. She cannot discriminate within, but across groups. A committee with representatives...
