We study the political economy of allocation decisions within a major state investment bank. Our focus is the European Investment Bank (EIB) - "The Bank of the EU" - which is the largest multilateral lending (and borrowing) institution in the world. We collect (and make available) information on...

I investigate if, how, and why the effect of a contribution rule in a public goods game depends on how it is implemented: endogenously chosen or externally imposed. The rule prescribes full contributions to the public good backed by a nondeterrent sanction for those who do not comply. My...

As an example of supranational climate policy coordination for sectors not covered by carbon trading, the European Effort Sharing Decision set national targets for emission reductions for the time period 2013-2020. Member States were free to decide the national policies to implement to achieve...

From a current perspective the Paris Agreement is not sufficient to limit the global mean temperature below 2êC above pre-industrial level as intended. The Agreement stipulates that parties review, compare and ratchet up efforts to combat climate change over time. Within this process,...

The establishment of a sovereign debt restructuring mechanism (SDRM) is one of the important issues in the academic debate on a viable constitution for the European Monetary Union (EMU). Yet the topic seems to be taboo in official reform contributions to the debate. Against this backdrop, the...

Out of a total of 2,976 double tax agreements (DTAs), some 60% are signed between a developing and a developed economy. As DTAs shift taxing rights from capital importing to capital exporting countries, the prior would incur a loss. We demonstrate in a theoretical model that in a deal one...

International climate negotiations have so far failed to produce ambitious climate cooperation. We combine laboratory experiments with simulations to investigate the performance of two negotiation design features to address this failure: The Paris Agreement's ratchet-up mechanism, which requires...

Microcredit, a financial tool providing uncollateralized loans to low-income individuals, has seen a shift from joint-liability (JL) to individual liabil- ity (IL) lending models. This article tests a theory explaining this shift, focusing on borrowers matching into groups exposed to similar...

Review systems including quantitative measures as well as text-based expression of experiences are omnipresent in today's digital platform economy. This paper studies the existence of reputation inflation, i.e. unjustified increases in ratings, with a special focus of heterogeneity between...

A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners' dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they...
