We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

Members of an illegal armed organization reveal their desertion minimum values in reaction to the incentives offered by a government. Depending on the organization’s network structure, the desertion of an individual member will unleash a contagion process that will destroy the local network at...

This paper provides deterministic approximation results for stochastic processes that arise when finite populations recurrently play finite games. The deterministic approximation is defined in continuous time as a system of ordinary differential equations of the type studied in evolutionary game...

Abstract We study models of the formation of citation networks in a setting where authors/firms care about their citations and are rational. The effect of these two features on the diffusion of useful ideas in a setting with complete information about past citations leads to multiplicity of...

Purpose – The purpose of this paper is to investigate the effects of product substitutability on sales performance of integrated and decentralised supply chains. The authors model supply chain performance effects by applying a Cournot equation to a combination of different industry...

Purpose – To make a theoretical comparison between two scale‐inspection and warranty policies for weight‐quality, one practical and the other theoretically grounded. Design/methodology/approach – Comparison is made in a Stackelberg game framework considering the consumer's as well as the...

Purpose – The purpose of this paper is to investigate knowledge sharing (KS) to characterize its behavior in companies based on the concepts of theory of reasoned action and game theory (GT). Design/methodology/approach – The paper proposes two models: Model A: KS process is constructed by...

Purpose Based on the background of enterprise digital transformation, this paper aims to examine the impact of digitization on the cooperative behavior and environmental performance of green technology innovation. Design/methodology/approach By constructing a model of quantity competition...

Purpose This paper considers a supply chain with a manufacturer (she) selling through an online retail platform (he) and studies the channel structure choices of two firms when investing in advertising. Design/methodology/approach The authors assume that the platform provides the manufacturer...
