This paper examines the effects of underwriter networks in the market of securitized products. The complexity and opacity of securitized products increase the value of information gathered and disseminated to the market by central underwriters. However, securitized deals have long performance...

We provide an empirical analysis of the investments' network of investors and startups, using original data from the entrepreneurial finance setting in California. We also propose, and calibrate a two-mode random network formation model. We show that an essential mechanism of the entrepreneurial...

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...

This paper develops strategic foundations for an important statistical model of random networks with heterogeneous expected degrees. Based on this, we show how social networking services that subtly alter the costs and indirect benefits of relationships can cause large changes in behavior and...

We use a purposely-designed survey on Sri Lankan immigrants living in Milan to study their personal network. By taking a dyadic perspective we investigate how migrants form (weak and strong) social links among them in the host country, and the extent to which this network provides them material...

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...

Growing evidence suggests that many social and economic networks are scale free in that their degree distribution has a power-law tail. A common explanation for this phenomenon is a random network formation process with preferential attachment. For a general version of such a process, we develop...

Social media have great potential to support diverse information sharing, but there is widespread concern that platforms like Twitter do not result in communication between those who hold contradictory viewpoints. Because users can choose whom to follow, prior research suggests that social media...

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...

In many contexts an individual's beliefs and behavior are affected by the choices of his or her social or geographic neighbors. This influence results in local correlation in people's actions, which in turn affects how information and behaviors spread. Previously developed frameworks capture...
