Partner selection is an important process in many social interactions, permitting individuals to decrease the risks associated with cooperation. In large populations, defectors may escape punishment by roving from partner to partner, but defectors in smaller populations risk social isolation. We...

Motivated by recent auctions of licenses for the radio frequency spec trum, we consider situations where multiple objects are auctioned simultaneousl y by means of a second-price, sealed-bid auction. For some buyers, called globa l bidders, the value of multiple objects exceeds the sum of the...

The theoretical literature on exchange of indivisible goods finds natural application in organizing the exchange of live donor kidneys for transplant. However, in kidney exchange, there are constraints on the size of feasible exchanges. Initially, kidney exchanges are likely to be pairwise...

Two players play an unknown zero-sum repeated game. Before the game starts one player may receive signals, whose nature is specified by an information structure, regarding the game actually played. We characterize when one information structure is better for the maximizer than another. We also...

The paper discusses coordination games with remote players that have access to an entangled quantum state. It shows that the entangled state cannot be used by players for communicating information, but that in certain games it can be used for improving coordination of actions. A necessary...

Varying quantities of a single good can be produced using at least two and at most $n$ factors of production. The problem of allocating the surplus among the factors is studied in a dynamic model with adaptive behavior. Representatives for the factors (called players) make wage demands based on...

Speculation in asset market is modelled as a stochastic betting game played by finite number of players and repeated infinite times. With stochastic asset return and unkown quality of public signal, a generic adaptive learning rule is proposed and the corresponding evolutionary dynamics is...

This paper contributes to the literature on second-price auctions with resale. We add speculators---bidders with value zero---to the standard symmetric independent private values environment. There always exists a continuum of inefficient equilibria that are profitable for a speculator. With no...

The study of the social system in Indonesian mining site needs a unique approach as the social system there cannot be categorized easily as urban or even rural society. It is obvious that in the mining site sociology we can model the three main role-players: regional government, mining...
