We examine the endogenous formation of research coalitions with high spillovers among symmetric firms. Members of a research coalition set their R&D investments in order to maximise the aggregate profits of members of their coalition. The Exclusive membership rule supports a more "concentrated"...

We study frictionless matching models in large production economies with and without market imperfections and/or incentive problems. We provide necessary and sufficient distribution-free conditions for monotone matching which depend on the relationship between what we call the segregation payoff...

International environmental agreements aiming at correcting negative externalities generated by transboundary pollution are difficult to achieve for many reasons. Important obstacles arise from asymmetry in costs and benefits, and instability may occur due to the fact that coalitions of...

This paper provides a game-theoretic model of representative democracy with endogenous party formation. Coalition formation may occur before and after elections, and the expected payoffs from the after-election majority game affect incentives to form parties before the elections. In this way...

Debt swaps as an instrument of international co-operation in environmental field were conceived and first applied in the 1980s. They were once thought of as "win-win" arrangements solving environmental and economic problems at the same time. In the 1990s it became clear, however, that (1)...

We use an extensive form, universal type space to provide the following epistemic characterisation of extensive form rationalisability. Say that player i strongly believes event E if i is certain of E conditional on each of her information sets consistent with E. Our main contribution is to show...

In this paper we extend a model by A. Ulph (1997) on the relationship between free trade agreements, environmental regulation and trade under imperfect competition. Ulph's model focused on the effectiveness of harmonisation policies against ecological dumping. It turned out that harmonised...

The purpose of the paper is to narrow the gap between the widespread use of voluntary agreements and research on the rationale of such approaches. A typical example are voluntary agreements of many industries to reduce carbon dioxide emissions because of global warming. If the industry...

Multinational enterprises (MNEs) have started to populate also regulated sectors. Their linked international activities and credible threats to relocate are then new concerns for regulators. We study a multiprincipal model in which a privately informed MNE (the agent) produces for two countries...

This paper surveys the recent literature devoted to the analysis of the interactions between the adoption of voluntary or negotiated agreements as a tool of environmental policy and market structure. The goal of this survey is twofold. On the one hand, we would like to identify the market...
