We examine the formation of multilateral, hub-and-spoke and bilateral international R&D strategic alliances (overlapping climate clubs) to reduce CO2 emissions. R&D provision in clubs produces two types of positive externalities: a global public good (i.e., reduction of CO2 emissions) and...

Naturwissenschaftliche Fragen rund um den Klimawandel sind von Naturwissenschaftlern zu beantworten. Ökonomen und Wirtschaftsethiker können jedoch dazu beitragen, den Klimawandel und mögliche Gegenmaßnahmen zu bewerten. Dabei ist ein einheitlicher Preis für die Emission von Treibhausgasen...

Within the context of the Global Crisis, this paper examines the ongoing policy challenges in establishing a European framework for financial regulation and supervision. We do so taking into account the evidence provided during the crisis of pervasive spillover effects and cross-country...

Greenhouse gas abatement is a public good, so climate policy is a public-goods game and suffers from the free-rider incentives that make the outcome of such games notoriously uncooperative. Adopting an international agreement can change the nature of the game, reducing or exacerbating the...

This paper solves the global cap-and-trade game exactly as the public-goods game is normally solved and finds a problematic outcome. Abatement of greenhouse gas emissions is a global public good, and supplying a public good is a game with strong incentives to free ride. Adding a cap-and-trade...

Climate negotiations have largely failed, so a change of course is required. This requires that a sizable group of experts recommend a small, clear set of policy guideposts that lead to a more cooperative treaty. This papers proposes a set of three guideposts and derives them from an analysis of...

The Kyoto summit initiated an international game of cap and trade. Unlike a national policy, the essence of this game is the self-selection of national emission targets. This differs from the standard global public-goods game because targets are met in the context of a global carbon market. This...

In the course of history, a large number of politicians have been assassinated. Rational choice hypotheses are developed and tested using panel data covering more than 100 countries over a period of 20 years. Several strategies, in addition to security measures, are shown to significantly reduce...

A group of agents wants to reform the status quo if and only if this is Pareto improving. Agents have private information and may have common or private objectives, which creates a tension between information aggregation and minority protection. We analyze a simple voting system - majority rule...

Natural disasters have been a major cause of human suffering. Countries with higher income, lower inequality, lower corruption, and more democratic regimes have been found to experience less casualties from disasters. Government repression, however, could also play a role in disaster...
