Weitzman (2014) proposed that focusing international climate negotiations on a uniform carbon price is more effective than Paris style negotiations in achieving ambitious climate action. We put this hypothesis to an experimental test by simulating international negotiations on climate change in...

International cooperation on the reduction of greenhouse gas emissions, disarmament, or free trade needs to be negotiated. The success of such negotiations depends on how they are designed. In the context of international climate change policy, it has been proposed [e.g., Weitzman J of the...

In seiner Thünen-Vorlesung vor dem Verein für Socialpolitik im Herbst 2020 hat Klaus Schmidt das Design von Klimaschutzverhandlungen untersucht. Er geht dabei von einem Vorschlag Martin Weitzmans aus, künftige Verhandlungen auf einen einheitlichen CO2-Mindestpreis zu fokussieren. Wäre ein...

Open access (OA) publishing upends the traditional business model in scientific publishing by requiring authors instead of readers to pay for the publishing-related costs. In this paper, we aim to elicit the willingness to pay (WTP) of authors for open access publishing. We conduct two separate...

It is widely believed that an environmental tax (price regulation) and cap-and-trade (quantity regulation) are equally efficient in controlling pollution when there is no uncertainty. We show that this is not the case if some consumers (firms, local governments) are morally concerned about...

The public acceptability of a carbon price depends on how the revenues from carbon pricing are used. In a fully incentivised experiment with a large representative sample of the German population, we compare five different revenue recycling schemes and show that support for a carbon price is...

Reference-dependent preferences can explain several puzzling observations about organizational change. We introduce a dynamic model in which a loss-neutral firm bargains with loss-averse workers over organizational change and wages. We show that change is often stagnant or slow for long periods...

Loss aversion postulates that people prefer avoiding losses over acquiring gains of equal size. It is a central part of prospect theory and, according to Daniel Kahneman, “the most significant contribution of psychology to behavioral economics” (Kahneman, 2011, p. 300). It has powerful...

We report on two experiments that identify non-monetary incentive effects of competition. As the number of competitors increases, monetary incentives to engage in cost reduction tend to decrease. We test the hypothesis that there are non-monetary incentive effects of competition going in the...

The procurement of complex projects is often plagued by large cost overruns. One important reason for these additional costs are flaws in the initial design. If the project is procured with a price-only auction, sellers who spotted some of the flaws have no incentive to reveal them early. Each...
