Negative Reciprocity: The Coevolution of Memes and Genes

Friedman, Daniel; Singh, Nirvikar - EconWPA - 2004

sustaining cooperative behavior but highlight an intrinsic free-rider problem: the fitness benefits of negative reciprocity are …A preference for negative reciprocity is an important part of the human emotional repertoire. We model its role in … reciprocity is a meme consisting of a group norm together with low-powered (and low-cost) group enforcement of the norm. The main …

Metabolism of Social System: N-Person Iterated Prisoner’s Dilemma Analysis In Random Boolean Network

Situngkir, Hokky; Khanafiah, Deni - EconWPA - 2004

Random Boolean Network has been used to find out regulation patterns of genes in organism. This approach is very interesting to use in a game such as N-Person Prisoner’s Dilemma. Here we assume that agent’s action is influenced by input in the form of choices of cooperate or defect she...

Capital account Liberalization and exchange rate regime choice, What Scope for flexibility in Tunisia ?

Sami, Ben Ali Mohamed - EconWPA - 2005

Capital account liberalization and exchange rate regime choice, what scope for flexibility in Tunisia? The adoption by Tunisia of structural reforms of its economy in a context of gradual opening since 1986, had allowed the instauration in January 1993 of the convertibility of its current...

What restrictions do Bayesian games impose on the value of information?

Lehrer, Ehud; Rosenberg, Dinah - EconWPA - 2003

In a Bayesian game players play an unknown game. Before the game starts some players may receive a signal regarding the specific game actually played. Typically, information structures that determine different signals, induce different equilibrium payoffs.In zero-sum games the equilibrium payoff...

Voting and Lottery Drafts as Efficient Public Goods Mechanisms

Ledyard, John O.; Palfrey, Thomas R. - EconWPA - 1994

This paper characterizes interim efficient mechanisms for public good production and cost allocation in a two-type environment with risk neutral, quasi-linear preferences and fixed size projects, where the distribution of the private good, as well as the public goods decision, affects social...

On the Relation Between Perfect Equilibria in Extensive Form Games and Proper Equilibria in Normal Form Games

Hillas, John - EconWPA - 1996

This paper examines the question of the extent to which it is true that any equilibrium that is quasi-perfect in any extensive form game having a given normal form is necessarily proper. If one fixes not only the equilibrium in question but also a a sequence of completely mixed strategies...

A Consumer-Based Model of Competitive Diffusion of Two Goods: The Effects of Network Externalities and Local Interactions

Tomochi, Masaki; Murata, Hiroaki; Kono, Mitsuo - EconWPA - 2002

The diffusion of two competitive, interchangeable, and durable goods is studied under the framework of a spatial game where consumers are distributed on a two-dimensional square lattice and play 3$\times$3 symmetric coordination-like games with their nearest neighbors. There are three...

Topology-Free Typology of Beliefs

Heifetz, Aviad; Samet, Dov - EconWPA - 1996

In their seminal paper, Mertens and Zamir (1985) proved the existence of a universal Harsanyi type space which consists of all possible types. Their method of proof depends crucially on topological assumptions. Whether such assumptions are essential to the existence of a universal space remained...

A Game Theoretic Approach to Computer Science: Survey and Research Directions

GALLO, Crescenzio - EconWPA - 2005

Theoretical Computer Science classically aimed to develop a mathematical understanding of capabilities and limits of traditional computing architecture (Boole, von Neuman, Turing, Church, Godel), investigating in computability, complexity theory and algorithmics. Now it seems more natural to...

AN EVOLUTIONARY INTERPRETATION OF MIXED-STRATEGY EQUILIBRIA

Oechssler, Joerg - EconWPA - 1994

One of the more convincing interpretations of mixed strategy equilibria describes a mixed equilibrium as a steady state in a large population in which all players use pure strategies but the population as a whole mimics a mixed strategy. To be complete, however, this interpretation requires a...
