We consider an economy in which agents are embedded in a network of potential value-generating relationships. Agents are assumed to be able to participate in three types of economic interactions: Autarkic self-provision; bilateral interaction; and multilateral collaboration. We introduce two...

We study the effect of learning another language on the social and individual welfare by a people group who do not know that language. We use network economics approach in order to take into account the externalities of languages. The equilibrium with decentralized choices is not as good as the...

Suppose markets and firms are connected in a bi-partite network, where firms can only supply to the markets they are connected to. Firms compete a la Cournot and decide how much to supply to each market they have a link with. We assume that markets have linear demand functions and firms have...

We study the effects of network externalities on a unique matching protocol for faculty in a large U.S. professional school to offices in a new building. We collected institutional, web, and survey data on faculty's attributes and choices. We first identify the different layers of the social...

This paper examines stability and efficiency of the Walrasian equilibrium outcome in a decentralized two-sided networked market, where any pair of a buyer and a seller must be connected by a link to engage in trading. In this networked market, buyers and sellers first form a network and then...

Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cummulate in 'stocks' affecting agents' welfare and incentives. For instance, smoking is subject...

We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network structure. We discuss, in particular, the impact of the structure of the network on individuals' behaviors. We focus on game theoretic modeling, but also include some discussion...

After a decade of bruising legal battles, the courts and software industry norms largely resolved the costly war over the scope of copyright protection for computer software. By the mid 1990s, freedom to develop interoperable devices, systems, and software triumphed over broad copyright...

The present study analyzes how can positive network externalities in the form of network effects exert significant influence over the characterization of ‘market access’ in the context of high-technology markets. Throughout the last two decades there has been a vast body of literature...

In light of recent trends in social networking services that encourage users of platforms to “share,” “recommend,” and “do activities” with others, this work analyzes platform competition in two-sided markets that exhibit direct (or within-) network effect in addition to conventional...
