We study two n-player sequential network formation games with externalities. Link formation is tied to simultaneous transfer selection in a Nash demand like game in each period. Players in groups can counterpropose. We give necessary and sufficient conditions for efficiency in terms of cyclical...

Decentralized matching markets on the internet allow large numbers of agents to interact anonymously at virtually no cost. Very little information is available to market participants and trade takes place at many different prices simultaneously. We propose a decentralized, completely uncoupled...

We generalise the coalition structure core to partition function games. Our definition relies only on one crucial assumption, namely that there is some internal consistency in the game: residuals of the deviation play a game similar to the initial one, and – whenever this is possible – they...

This research examines the economic origins of Islam and uncovers two empirical regularities. First, Muslim countries, virtual countries and ethnic groups, exhibit highly unequal regional agricultural endowments. Second, Muslim adherence is systematically larger along the pre-Islamic trade...

This paper compares the saving behavior of formal and informal workers and additionally provides a socioeconomic and financial characterization of informal workers in Chile. The paper uses the Financial Household Survey conducted by the Central Bank of Chile in 2007, 2008, 2009 and 2010, which...

I study the coexistence of formal and informal finance in underdeveloped credit markets. While weak institutions constrain formal banks, shallow pockets hamper informal lenders. In such economies, informal finance has two effects. By increasing the investment return it decreases borrowers'...

Limited borrower information may create targeting distortions in credit markets. Community-based lending programs may reduce these distortions by exploiting information transmitted in local networks, but connections may create asymmetries in power. This paper analyzes how local leaders balance...

We examine merger activity and its effect on asset pricing in a firm network economy. Mergers create internal capital markets which change the cash flow risk structure of the merging firms. We propose a solution concept for coalitional games without the superadditivity axiom, which extends...

In a common value auction in which the information partitions of the bidders are connected, all rings are core-stable. More precisely, the ex ante expected utilities of rings, at the (noncooperative) sophisticated equilibrium proposed by Einy, Haimanko, Orzach and Sela (Journal of Mathematical...

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect...
