This conceptual paper investigates the creation of interlocking directorate ties focusing on firms’ choice between sent, received, and undirected board interlocks. Drawing on a framework on the benefits of board interlocks stemming from resource dependence theory, we synthesize prior research...

We propose a model for the evolution of market share in presence of social influence. We study a simple market in which the individuals arrive sequentially and choose one of the available products. Their decision of which product to choose is a stochastic function of the inherent quality of the...

A firm’s choices can shape patterns of consumer communication about its product. This paper examines the problem for a firm that can both set price and target sales when selling a product of hidden, exogenous quality over two sales rounds to consumers who share information locally with their...

This paper studies the phenomenon of early hiring in entry-level labor markets (e.g. the market for gastroenterology fellowships and the market for judicial clerks) in the presence of social networks. We offer a two-stage model in which workers in training institutions reveal information on...

This paper studies the impact of collaboration on research output. First, we build a micro founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...

We study learning and influence in a setting where agents communicate according to an arbitrary social network and naively update their beliefs by repeatedly taking weighted averages of their neighbors' opinions. A focus is on conditions under which beliefs of all agents in large societies...

Global sourcing can increase firms’ productivity via the quality upgrading of intermediates, but, because of the heterogeneity of suppliers, it also increases screening costs of final firms given the need to search for good suppliers. We build up a simple model to analyze these factors and...

I discuss a fundamental and pervasive aspect of social networks that has a signfii cant impact on behavior: "homophily. "Homophily refers to the tendency of individuals to associate with others who have similar characteristics as themselves. This tendency has been observed across a variety of...

This paper applies for the first time power index analysis to the famous Krackhardt’s kite social network by imposing a weighted voting game on the given network structure. It compares the results of this analysis, derived by applying the Public Good Index and the Public Value, with the...

I model dynamic product design along price and non-price dimensions by a firm in a market with positive network externalities between consumers. In the case of a usage fee, I provide conditions under which the steady state (SS) is unique and show that the introductory price is negative and...
