[PDF] Endogenous formation of cooperation structures

[PDF] from upi-yptk.ac.id
Full text - MIT Libraries
CZ Qin - Journal of Economic Theory, 1996 - upi-yptk.ac.id
This paper presents an approach for studying how cooperation among players in a
coalitional game might arise endogenously. The approach begins with Myerson's [10]
general representation of a cooperation structure as a set of undirected bilateral links ...

Are Cournot and Bertrand equilibria evolutionary stable strategies?

Full text - MIT Libraries
CZ Qin… - Journal of Evolutionary Economics, 1997 - Springer
Maynard Smith (1972) proposed a static notion of equilibrium for evolutionary games.
Roughly, an evolutionary stable strategy (ESS) is a strategy x that resists invasion in the
sense that any ''mutant''strategy that arises at a low rate in a population playing x tends to ...

Cores and competitive equilibria with indivisibilities and lotteries

Full text - MIT Libraries
R Garratt… - Journal of Economic Theory, 1996 - Elsevier
Lotteries are introduced in the exchange model of Shapley and Scarf (J. Math. Econ. 1
(1974), 23-37). In competition, traders buy and sell probabilities on houses. When
considering the core, feasible allocations of the economy and blocking allocations of ...

Bertrand versus Cournot revisited

Full text - MIT Libraries
CZ Qin… - Economic Theory, 1997 - Springer
Summary. Bertrand criticized Cournot's analysis of the competitive process, arguing that
firms should be seen as playing a strategy of setting price below competitors' prices
(henceforth, the Bertrand strategy) instead of a strategy of accepting the price needed to ...

R Garratt… - Journal of Economic Theory, 1997 - Elsevier
Given a game, the set of joint lotteries over partitions of the agents of any subgame induces
a subset of the vectors of balancing weights for the subgame. Games whose subgames are
all balanced with respect to these vectors of balancing weights are called totally L- ...
