We analyze a team formation process that generalizes matching models and network formation models, allowing for overlapping teams of heterogeneous size. We apply different notions of stability: myopic team-wise stability, which extends to our setup the concept of pair-wise stability, coalitional...

A recent advance in our understanding of repeated PDs is the detection of a threshold d* at which laboratory subjects start to cooperate predictively. This threshold is substantially above the classic threshold "existence of Grim equilibrium" and has been characterized axiomatically by Blonski,...

Exogenously imposed infinite repetition is known to mitigate people’s uncooperative behaviors in dilemma situations with partner matching through personal enforcement. One as yet unanswered question is whether people collectively choose to interact with each other under the partner matching...

We investigate how reputational uncertainty and the rate of change of the social environment interact to influence cooperation in social networks. Reputational uncertainty significantly decreases cooperation and welfare, induces more forgiveness toward defectors, and promotes opportunistic play....

The article analyzes the realpolitik strategic offensive behavior of PRC’s centralized banking after joining the GATT and WTO. With the Bretton Woods and issuance of USD anchored to gold, the PRC State-owned Assets Supervision and Administration (SASAC) of the import-export control regime...

In the repeated Prisoner's Dilemma, predictions are notoriously difficult. Recently, however, Blonski, Ockenfels, and Spagnolo (2011, BOS) showed that experimental subjects predictably cooperate when the discount factor exceeds a particular threshold. I show that this threshold implies existence...

The authors (Cason, Friedman and Hopkins, Review of Economic Studies, 2014) claimed that control treatments (using simultaneous matching in discrete time) replicate previous results that exhibit weak or no cycles. After correcting two mathematical mistakes in their cycles tripwire algorithm, we...

This paper proposes an evolutionary framework to explore the dynamics of social interaction in an environment characterized by online networking and increasing pressure on time. The model shows how time pressure encourages the choice to develop social interactions also through online networking...

In a variety of settings, some payoff-relevant item spreads along a network of connected individuals. In some cases, the item will benefit those who receive it (for example, a music download, a stock tip, news about a new research funding source, etc.) while in other cases the impact may be...
