In this paper, I develop and estimate a dynamic model of strategicnetwork formation with heterogeneous agents. The main theoretical resultis the existence of a unique stationary equilibrium, which characterizesthe probability of observing a specific network in the data. As aconsequence, the...

Actors often leave in pursuit of new ventures, even though entrepreneurial opportunities may exist inside the firm. While a bulk of work has focused on understanding the determinants of entrepreneurial transition (e.g., Aldrich and Ruef, 2006; Dobrev and Barnett, 2005; Robinson and Sexton, 1994; Sørensen,...

As the popularity of social networks expands, the information users expose to the public has potentially dangerous implications for individual privacy. While social networks allow users to restrict access to their personal data, there is currently no mechanism to enforce privacy concerns over...

In three chapters I study the formation of social networks, and the impact the structures that arise may have in various economic settings. First, I develop a model of social network formation with heterogeneous agents and incomplete information. The model predicts an equilibrium in which agents...

Good reputation management is becoming increasingly important as organisations and the social environments in which they function become more complex (Caruana, 2000; Fombrun & van Riel, 2003). Organisations are being evaluated by far more demanding standards than in the past, and are increasingly...
