چکیده
Social Insurance Networks Based on administrative panel data from Norway, we examine how social insurance dependency spreads within neighborhoods, families, ethnic minorities, and among former schoolmates. We use a fixed effects methodology that accounts for endogenous group formation, contextual interactions, and time-constant as well as time-varying confounders. We report evidence that social insurance dependency is contagious. The estimated network effects are both quantitatively and statistically significant, and they rise rapidly with “relational closeness” in a way that establishes endogenous social interaction as a central causal mechanism. Social interactions do not cross ethnic borders. JEL Classification: C31, H55, I38

متن کاملSolving the Organizational Free Riding Problem with Social Networks
We describe how social networks can help reduce certain situations of free riding in organizations. The technique uses the homophily of an organization’s social network to select an advisory monitoring peer group likely to share knowledge and skills with each participant, and therefore most able to detect free riding in situations requiring those skills. We illustrate this application in the co...
