Problem Definition and Academic/Practical Relevance: Most supply networks are characterized by firms that source from multiple suppliers and suppliers that serve multiple firms, thus resulting in suppliers who differ in their degree centrality, i.e., the number of firms they supply to. In such...

This paper proposes a dynamic model for the process of industry consolidation by sequences of mergers and acquisitions that create synergy gains to merging firms and may impose positive or negative externalities on the remaining firms in the industry. We allow firms to make acquisition offers...

We study how the procurement process may help a buyer reduce purchasing costs under a dual-sourcing setting. First, we analyze the equilibrium outcomes when the buyer simultaneously or sequentially bilaterally negotiates with the suppliers. We establish coordination results and characterize the...

In this paper we apply the so-called partition function approach to study coalition formation in the North-east Atlantic mackerel fishery in the presence of externalities. Atlantic mackerel is mainly exploited by the European Union (EU), the United Kingdom (UK), Norway, the Faroe Islands and...

We model decentralized team formation as a game in which players make offers to potential teams whose members then either accept or reject the offers. The games induce no-delay subgame perfect equilibria with unique outcomes that are individually rational and match soulmates. We provide...

This paper surveys the recent literature on the endogenous formation of economic coalitions, in particular, the partition function literature that allows for externalities across coalitions. Various economic coalitions are classified either as coalitions with positive externalities (output...

This paper surveys implementation theory when players have incomplete or asymmetric information, especially in economic environments. After the basic problem is introduced, the theory of implementation is summarized. Some coalitional considerations for implementation problems are discussed. For...

We study the implementation of social choice rules in environments with externalities. We prove the impossibility of implementing efficient and α-individually rational rules in dominant strategies. We prove that the α-core is implementable in Nash equilibrium under mild restrictions and it is...

The Nash program is an important research agenda initiated in Nash (1953) in order to bridge the gap between the noncooperative and cooperative counterparts of game theory. The program is thus turning sixty-seven years old, but I will argue it is not ready for retirement, as it is full of energy...

n the analysis of value capture, it is central to understand what value each group of players can capture when leaving the negotiation table. Frequently, this will entail engaging in competition, i.e., non-negotiated, strategic interactions with the other players. For instance, if merger talks...
