The EU steps up its efforts to curb its territorial CO2-emissions. It is planning to introduce a carbon border adjustment mechanism (CBAM) to level the playing field and to raise own resources. However, unilateral European climate policy action, whether shored up with a CBAM or not, can only...

In many cultures and industries gifts are given in order to influence the recipient, often at the expense of a third party. Examples include business gifts of firms and lobbyists. In a series of experiments, we show that, even without incentive or informational effects, small gifts strongly...

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...

For the procurement of complex goods the early exchange of information is important to avoid costly renegotiation. If the buyer can specify the main characteristics of possible design improvements in a complete contingent contract, a scoring auction implements the efficient allocation. If this...
