Smiling contributions: Social control in a public goods game with network decline

Takács, Károly; Janky, Béla - In: Physica A: Statistical Mechanics and its Applications 378 (2007) 1, pp. 76-82

Previous models of collective action assume that the network structure of individual relations that transmit social control mechanisms promoting or inhibiting collective action is given. An extended game-theoretical model that incorporates social control mechanisms as side payments and allows...

Dynamic behavior of discrete-time multiagent systems with general communication structures

Xiao, Feng; Wang, Long - In: Physica A: Statistical Mechanics and its Applications 370 (2006) 2, pp. 364-380

weakly connected topologies. By using matrix theory, we prove that the states of internal agents will converge to a convex …

Collective states in social systems with interacting learning agents

Semeshenko, Viktoriya; Gordon, Mirta B.; Nadal, Jean-Pierre - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 19, pp. 4903-4916

We study the implications of social interactions and individual learning features on consumer demand in a simple market model. We consider a social system of interacting heterogeneous agents with learning abilities. Given a fixed price, agents repeatedly decide whether or not to buy a unit of a...

The merchandising mathematician model: profit intensities

Piotrowski, E.W.; Sładkowski, J. - In: Physica A: Statistical Mechanics and its Applications 318 (2003) 3, pp. 496-504

A simple model of a buying–selling cycle is proposed. It is based on a notion of a profit intensity. Supply and demand curves and geometrical interpretation are discussed in this context.

A decision theoretical approach for diffusion promotion

Ding, Fei; Liu, Yun - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 17, pp. 3572-3580

In order to maximize cost efficiency from scarce marketing resources, marketers are facing the problem of which group of consumers to target for promotions. We propose to use a decision theoretical approach to model this strategic situation. According to one promotion model that we develop,...

Sex-oriented stable matchings of the marriage problem with correlated and incomplete information

Caldarelli, Guido; Capocci, Andrea; Laureti, Paolo - In: Physica A: Statistical Mechanics and its Applications 299 (2001) 1, pp. 268-272

In the stable marriage problem two sets of agents must be paired according to mutual preferences, which may happen to conflict. We present two generalizations of its sex-oriented version, aiming to take into account correlations between the preferences of agents and costly information. Their...

An evolutionary game theory model of binary opinion formation

Ding, Fei; Liu, Yun; Shen, Bo; Si, Xia-Meng - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 8, pp. 1745-1752

, which could be hopefully described by cooperative games in the evolutionary game theory framework. This paper presents game … theory methods to model the formation of binary opinions: cooperative games are proposed to model the interaction rules of … game theory models show evolutionary results similar to traditional opinion models. Specially, the evolution of opinions …

Social aggregation as a cooperative game

Vilone, Daniele; Guazzini, Andrea - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 14, pp. 2716-2727

A new approach for the description of phenomena of social aggregation is suggested. On the basis of psychological concepts (as for instance social norms and cultural coordinates), we deduce a general mechanism for social aggregation in which different clusters of individuals can merge according...

Uncertainty of cooperation in random scale-free networks

Arapaki, Eleni - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 13, pp. 2757-2761

We study the spatial prisoner’s dilemma game where the players are located on the nodes of a random scale-free network. The prisoner’s dilemma game is a powerful tool and has been used for the study of mutual trust and cooperation among individuals in structured populations. We vary the...
