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,...

Illiquidity Premium and Expected Stock Returns in the UK : A New Approach

Chen, Jiaqi - 2017

This study examines the relative importance of liquidity risk for the time-series and cross-section of stock returns in the UK. We propose a simple way to capture the multidimensionality of illiquidity. Our analysis indicates that existing illiquidity measures have considerable asset specific...

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 …
