This paper analyses stability of coalitions for greenhouse gas abatement for different sharing rules applied to the gains from co-operation. We use a 12-regions model designed to examine internal and external stability of coalitions (STACO). We compare different sharing rules like, for example,...

Almost all international environmental agreements include a minimum participation rule. Under such a rule an agreement becomes legally binding if and only if a certain threshold in terms of membership or contribution is reached. We analyze a cartel game with open membership and heterogeneous...

We examine the formation of hub-and-spoke and multilateral green technology international agreements. Green R&D provision produces two types of positive externalities, a global public good (i.e., reduction of carbon dioxide emissions) and spillovers in technology agreements. We utilize the...

The Perfectly Coalition-Proof Nash equilibrium (PCPN) concept is extended to allow for the emergence of overlapping coalitions in equilibrium. We apply the extended concept to study the efficiency and stability properties of environmental agreements to control emissions of correlated continental...

We examine numerous settings in which large strategic nations make environmental policies in the presence of international trade and form coalitions that aim to mitigate global or continental transnational pollution. We show that every nation has incentives to internalize all emission...

This paper studies the efficiency of decentralized leadership in federations where selfish regional governments provide regional and federal public goods and the benevolent central government implements interregional earmarked and income transfers. Without residential mobility, unlimited...

Earmarked federal grants are ubiquitous and significant. Traditional fiscal federalism is unable to explain the widespread utilization of such grants. Recent arguments focusing on the potential benefits of centralized earmarking in reducing incentives for the creation of soft budgets at...

In a federation with decentralized leadership, many regional governments provide multiple types of public goods and the center implements interregional income transfers. The symmetric perfect equilibrium under unlimited decentralized leadership is inefficient because regional public goods are...
