We study the provision of a public good in a social network where links are directed, i.e., the information flows one way. Our results relate, through stochastic dominance, the equilibrium outcome of such a process with the out-degree distribution of the network.

In the many-to-one matching model with contracts, I provide new necessary and new sufficient conditions for the existence of a stable allocation. These new conditions exploit the fact that one side of the market has strict preferences over individual contracts.

We use the supply chain matching framework to study the effects of firm exit. We show that the exit of an initial supplier or end consumer has monotonic effects on the welfare of initial suppliers and end consumers but may simultaneously have positive and negative effects on intermediaries....

We show that the Nash demand game has the fictitious play property. We also show that almost every fictitious play process and its associated belief path converge to a pure-strategy Nash equilibrium in the Nash demand game.

For the class of shortest path games, we propose a family of new cost sharing rules satisfying core selection. These rules allocate shares according to some lexicographic preference relation. A computational procedure is provided. Our results relate to those of Tijs et al. (2011).

I develop a model where workers decide how hard to look for a job via formal and informal search channels. The intensity of formal search determines an individual’s arrival rate of offers. The strength of investment in informal search translates into a job contact network in which job offers...

We compare dictator and impunity games. In impunity games, responders can reject offers but to no payoff consequence to proposers. Because proposers act under impunity, we should expect the same behavior across games, but experimentally observed behavior varies. Responders indeed exercise the...

Consider a non-governmental organization (NGO) that can invest in a public good. Should the government or the NGO own the public project? In an incomplete contracting framework with split-the-difference bargaining, Besley and Ghatak (2001) argue that the party who values the public good most...

I show that bargaining impasse in Hörner and Vieille (2009) can be interpreted as the limit of bargaining delay: the maximal duration of the game increases unboundedly as the seller’s discount factor approaches the threshold level above which bargaining impasse occurs.
