HOW CAN SOCIAL HERDING ENHANCE COOPERATION?

SCHWEITZER, FRANK; MAVRODIEV, PAVLIN; TESSONE, CLAUDIO J. - In: Advances in Complex Systems (ACS) 16 (2013) 04, pp. 1350017-1

We study a system in which N agents have to decide between two strategies θi(i ∈ 1 … N), for defection or cooperation, when interacting with other n agents (either spatial neighbors or randomly chosen ones). After each round, they update their strategy responding nonlinearly to two...

AN AGENT-BASED MODEL OF TAX COMPLIANCE: AN APPLICATION TO THE SPANISH CASE

LLACER, TONI; MIGUEL, FRANCISCO J.; NOGUERA, JOSÉ A.; … - In: Advances in Complex Systems (ACS) 16 (2013) 04, pp. 1350007-1

In this paper, we present a new agent-based model for the simulation of tax compliance and tax evasion behavior (SIMULFIS). The main novelties of the model are the introduction of a "behavioral filter approach" to model tax decisions, the combination of a set of different mechanisms to produce...

A CONNECTIONIST ABM OF SOCIAL CATEGORIZATION PROCESSES

ROOY, DIRK VAN - In: Advances in Complex Systems (ACS) 15 (2012) 06, pp. 1250077-1

This paper introduces a connectionist Agent-Based Model (cABM) that incorporates detailed, micro-level understanding of social influence processes derived from laboratory studies and that aims to contextualize these processes in such a way that it becomes possible to model multidirectional,...

THE EFFECT OF SOCIAL INFLUENCE ON MARKET INEQUALITIES IN THE MOTION PICTURE INDUSTRY

DELRE, SEBASTIANO A.; BROEKHUIZEN, THIJS L. J.; JAGER, … - In: Advances in Complex Systems (ACS) 11 (2008) 02, pp. 273-287

In this paper we investigate the degree to which two social influences, namely imitation and coordinated consumption, effectuate inequalities in the motion picture industry. We develop an agent-based model based on micro movie visitors' decision-making that generates the observed macro market...

OPINIONS MANIPULATION: MEDIA, POWER AND GOSSIP

QUATTROCIOCCHI, WALTER; CONTE, ROSARIA; LODI, ELENA - In: Advances in Complex Systems (ACS) 14 (2011) 04, pp. 567-586

Despite the increasing diffusion of the Internet technology, TV remains the principal medium of communication. People's perceptions, knowledge, beliefs and opinions about matters of fact get (in)formed through the information reported on by the media.However, a single source of information (and...

A PÓLYA LATTICE MODEL TO STUDY LEVERAGE DYNAMICS AND CONTAGIOUS FINANCIAL FRAGILITY

CIRILLO, PASQUALE; GALLEGATI, MAURO; HÜSLER, JÜRG - In: Advances in Complex Systems (ACS) 15 (2012) su, pp. 1250069-1

We discuss a special Pólya lattice model to study cascading failures of firms in a simple industrial economy. In particular, every firm is represented by a Pólya-like urn, whose reinforcement is function of time, of the neighboring urns and their compositions, and of a random variable...

HETEROGENEITY, CORRELATIONS AND FINANCIAL CONTAGION

CACCIOLI, FABIO; CATANACH, THOMAS A.; FARMER, J. DOYNE - In: Advances in Complex Systems (ACS) 15 (2012) su, pp. 1250058-1

We consider a model of contagion in financial networks recently introduced in Gai, P. and Kapadia, S. [Contagion in …, heterogeneous balance sheet size and degree correlations between banks. We study the probability of contagion conditional on the … heterogeneous degree distributions are shown to be more resilient to contagion triggered by the failure of a random bank, but more …

DECISION SPREAD IN THE CORPORATE BOARD NETWORK

BATTISTON, STEFANO; WEISBUCH, GÉRARD; BONABEAU, ERIC - In: Advances in Complex Systems (ACS) 06 (2003) 04, pp. 631-644

The boards of large corporations sharing some of their directors are connected in complex networks. Boards are responsible for corporations' long-term strategy and are often involved in decisions about a common topic related to the belief in economical growth or recession. We are interested in...

NETWORK DEPENDENCE OF STRONG RECIPROCITY

MENDES, R. VILELA - In: Advances in Complex Systems (ACS) 07 (2004) 03, pp. 357-368

Experimental evidence suggests that human decisions involve a mixture of self-interest and internalized social norms which cannot be accounted for by the Nash equilibrium behavior of Homo Economicus. This led to the notion of strong reciprocity (or altruistic punishment) to capture the human...

REPUTATION FOR INNOVATING SOCIAL NETWORKS

CONTE, ROSARIA; PAOLUCCI, MARIO; SABATER-MIR, JORDI - In: Advances in Complex Systems (ACS) 11 (2008) 02, pp. 303-320

Reputation is a fundamental instrument of partner selection. Developed within the domain of electronic auctions, reputation technology is being been imported by other applications, from social networks to institutional evaluation. Its impact on trust enforcement is uncontroversial and its...
