In standard coalition games, players try to form a coalition to secure a prize and a coalition agreement specifies how the prize is to be split among its members. However, in practical situations where coalitions are formed, the actual split of the prize often takes place after the coalition...

The employment of capital is rival in nature. Small countries do not benefit from taxing its employment. By contrast, the use of digital services is non-rival and small countries do benefit from taxing expenditures on such services. In fact, some countries have already decided to tax digital...

Inter-country equity in the taxation of IP is a contentious issue. With its BEPS initiative, the OECD aims at taxing in accordance with value creation even though there are admitted difficulties in determining the actual place of value creation. The European Commission promotes the introduction...

We propose a smooth multibidding mechanism for environments where a group of agents have to choose one out of several projects. Our proposal is related to the multibidding mechanism (Pérez-Castrillo and Wettstein, 2002) but it is "smoother" in the sense that small variations in an agent's bids...

The OECD seeks to align transfer pricing and profit taxation with value creation but fails to provide a clear definition. This paper argues that value creation requires international cooperation and that the profit tax base should therefore be allocated according to standards commonly considered...

In unavoidable traffic accidents, autonomous vehicles (AVs) face the dilemma of protecting either the passenger(s) or third parties. Recent studies show that most people prefer AVs following a utilitarian approach by minimizing total harm. At the same time, however, they would adopt an AV only...

The Nationally Determined Contributions (NDCs) under the Paris Agreement fall short of the abatement needed to reach the 2°C target. Emissions trading could be a "costless" means to reduce the ambition gap if countries used their gains from trade for additional abatement. However, this requires...

Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern surrounding these technologies is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the...

This paper proposes a comprehensive perspective on the question of self-enforcing solutions for normal form games. While this question has been widely discussed in the literature, the focus is usually either on strict incentives for players to stay within the proposed solution or on strategic...

This paper analyses the formation of international environmental agreements (IEAs) under uncertainty, focusing on the role of learning and risk aversion. It bridges two strands of literature: one focused on the role learning for the success of IEA formation when countries are risk neutral and...
