This paper studies an evolutionary model of network formation with endogenous decay, in which agents benefit both from direct and indirect connections. In addition to forming (costly) links, agents choose actions for a coordination game that determines the level of decay of each link. We address...

I study a one-way flow connections model in which players are heterogeneous with respect to values and the costs of establishing a link. I first show that values and costs asymmetries are crucial in determining the level of connectedness of a network. Interestingly, unconnected equilibria are...

Das deutsche Forschungssystem ist stark segmentiert, und es gibt Hinweise darauf, dass die Kooperation zwischen den verschiedenen Institutionen verbesserungsbedürftig ist. Insbesondere der Vernetzung von Wissenschaft und Wirtschaft stehen sehr oft Barrieren entgegen. Als bedeutende Hemmnisse...

The paper studies how social connections affect firm-level hiring decisions and performance. We characterize the social connections of firms' employees using register data and for causal identification we use job displacements, which create directed positive shocks towards connected firms by...
