This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing … private information. In all treatments, the (efficient) equilibrium network has a "star" structure. With homogeneous agents …

We bring our model to the data by analyzing the coauthorship network of economists registered in … the coauthorship network. Moreover, we analyze funding instruments for individual researchers as well as research …

When workers send applications to vacancies they create a network. Frictions arise because workers typically do not … friction affects network formation, while the second coordination friction affects network clearing. We show that those … that can arise and the number of matches on a given network. Equilibria that exhibit wage dispersion are inefficient in …

Specifically, actions are either strategic substitutes or strategic … complements, and participants have either complete or incomplete information about the structure of a random network. Since … for reduced exposure to loss, and 2) uncertainty about the network structure makes it considerably more difficult to …
