In a large natural field experiment, we explore the effect of providing donors with the opportunity to choose the target country for their donations. We find that only a small fraction of donors use the option, which might reflect a reluctance to consider tradeoffs when those concern important,...

We test the importance of social norms for market interactions associated with negative real-world externalities in a large-scale experiment with a heterogeneous population sample from Germany. The majority of experimental participants refuses to trade, thus behaving in a moral way. Our data...

Matching schemes, where a party matches the contribution of others, reduce the effective price of a good and aim to foster its demand. We review the empirical literature on the effectiveness of these schemes in the context of public goods, especially in the field of charitable giving. As...

We investigate the dynamic effects of a charitable lottery and an income tax on donations. The analysis is based on a two-round dictator game with the subject's charity of choice as recipient and additional incentives in the first round only. The immediate effect of a charitable lottery leads to...

Understanding the way in which knowledge is technically produced and transferred, and how its diffusion path can be characterized is of fundamental importance for the performance of an economy. Although this fact seems to be plausible ex ante, the relevant literature so far has paid less...

This literature review analyses the impacts of the EU ETS on competitiveness focussing on existing simulation studies. We have identified the choice of the reference scenario as the most critical issue for an appropriate analysis of the relevant literature. We find, however, that effects of the...

This paper analyses the macroeconomic costs of environmental regulation in European energy markets on the basis of existing macroeconomic simulation studies. The analysis comprises the European emssion trading scheme, energy taxes, measures in the transport sector, and the promotion of renewable...

Despite of the apparent failure of the Kyoto Protocol with respect to environmental effectiveness, it has established a broad international mechanism that might be able to provide a global reduction of greenhouse gas emissions during a second commitment period. In this paper we investigate the...
