While studies in public management have identified personal attributes, job characteristics, and organizational rewards as key factors that influence affective organizational commitment, limited attention has been paid to the influence of social networks on affective commitment. Given that...

We recognize that some sharing relationships in social networks are reciprocated (undirected), while others are unreciprocated (directed). We find that in unreciprocated relationships transfers are likely to flow from more to less wealthy households, while reciprocated risk-sharing relationships...

This study advances our understanding of network dynamics by applying matching theory to examine entrepreneurs’ intentions to add new ties to their personal network. I propose that task complementarity and social similarity are important matching criteria that influence entrepreneurs’...

This chapter first reviews economic theories for why firms tie their products and then discusses our views concerning what this review implies concerning optimal antitrust policy for tying cases. The review considers efficiency rationales for tying, price discrimination rationales, and various...

We use variation in wind speeds at surfing locations in Switzerland as exogenous shifters of users' propensity to post content about their surfing activity onto an online social network. We exploit this variation to test whether users' online content generation activity has a causal effect on...

This paper examines social learning when only one of the two types of decisions is observable. Because agents arrive randomly over time, and only those who invest are observed, later agents face a more complicated inference problem than in the standard model, as the absence of investment might...

Literature on network formation typically assumes that people create and remove relations as to maximize their outcome in the network. It is mostly neglected that people might also care about the outcomes of others when creating and removing links. In the current paper, we develop an experiment...

We specify and implement a test for the importance of network effects in determining the establishments at which people work, using recently-constructed matched employer-employee data at the establishment level. We explicitly measure the importance of network effects for groups broken out by...

This paper examines how involuntarily-formed social networks affect individual labor market outcomes. Using a new dataset of WWI draftees linked to the 1930 census, I identify the effect of a military company's postwar employment on a veteran's employment. The marginal effect of an additional...

We recently showed that obesity can spread socially from person to person in adults (Christakis and Fowler 2007). A natural question to ask is whether or not these results generalize to a population of adolescents. Three separate teams of researchers have analyzed the National Longitudinal Study...
