This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is such that the benefit that an agent derives from the network she is located in depends on the maximum information that someone in her neighbourhood, including herself,...

We study private communication in social networks prior to a majority vote on two alternative policies. Some (or all) agents receive a private imperfect signal about which policy is correct. They can, but need not, recommend a policy to their neighbors in the social network prior to the vote. We...

Observational learning is typically examined when agents have precise information about their position in the sequence of play. We present a model in which agents are uncertain about their positions. Agents sample the decisions of past individuals and receive a private signal about the state of...

We study social learning in a social network setting where agents receive independent noisy signals about the truth. Agents naïvely update beliefs by repeatedly taking weighted averages of neighbors' opinions. The weights are fixed in the sense of representing average frequency and intensity of...

We conduct the first-ever study of actual searches done in a public tax disclosure system, analyzing about one million searches done in 2014 and 2015 in Norway. We characterize the social network these searches comprise, including its degree of homophily and reciprocation, and the demographics...

I empirically analyze the formation and transformation of corporate venture capitalists' (CVC) social networks and social capital. I investigate the resulting structural and relational changes illuminating the process of interorganizational knowledge transfer and innovation generation of CVC...

This paper assesses whether cross-border M&A decisions exhibit network effects. We estimate exponential random graph models (ERGM) and temporal exponential random graph models (TERGM) to evaluate the determinants of cross-country M&A investments at the sectoral level. The results show that...

Survey evidence suggests that firms are insufficiently aware of newly introduced R&D support measures due to the complexity of the public support landscape. As a result, adoption is slow and incomplete, implying that eligible firms leave money on the table. We hypothesize that a key coping...

The contribution of this thesis is to present a framework to analyse firms controlled by more than one board. The literature survey of Chapter 2 revealed that there is little recognition of this phenomenon and no accepted way to investigate firms governed by multiple control centres described as...

We investigate how the selection process of a leader affects team performance with respect to social learning. We use a lab experiment in which an incentivized guessing task is repeated in a star network with the leader at the center. Leader selection is either based on competence, on...
