We survey the literatures on the economic consequences of the structure of social networks. We develop a taxonomy of 'macro' and 'micro' characteristics of social inter-action networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

To better understand the way social networks operate in the labor market, we propose two simple models where individuals help each other finding a job. In the first one, job information flows between individuals having a link with each other and we show that an equilibrium with a clustering of...

Many studies have used self-reported dyadic data without exploiting the pattern of discordant answers. In this paper we propose a maximum likelihood estimator that deals with mis-reporting in a systematic way. We illustrate the methodology using dyadic data on inter-household transfers from the...

Using the regression discontinuity design of close gubernatorial elections in the U.S., we identify a significant and positive impact of the social networks of corporate directors and politicians on firm value. Firms connected to elected governors increase their value by 3.89%. Political...

The aim of this paper is to provide a new mechanism based on social interactions explaining why minority workers have worse labor-market outcomes than majority workers. Building on Granovetter's idea that weak ties are superior to strong ties for providing support in getting a job, we develop a...

Using an original dataset describing the career history of some 16,000 senior executives and members of the non-executive board of US, UK, French and German companies, we investigate gender differences in the use of social networks and their impact on earnings. There is a large gender wage gap:...

This paper examines how networks of professional contacts contribute to the development of the careers of executives of European and US companies. We build a dynamic model of career progression in which career moves both depend upon existing networks and contribute to the development of future...

We develop two different social network models with different economic foundations. In the local-aggregate model, it is the sum of friends' efforts in some activity that affects the utility of each individual while, in the local-average model, it is costly to deviate from the average effort of...

Delinquents are embedded in a network of relationships. Social ties among delinquents are modelled by means of a graph where delinquents compete for a booty and benefit from local interactions with their neighbors. Each delinquent decides in a non-cooperative way how much delinquency effort he...

This paper studies whether conformism behavior affects individual outcomes in crime. We present a social network model of peer effects with ex-ante heterogeneous agents and show how conformism and deterrence affect criminal activities. We then bring the model to the data by using a very detailed...
