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 explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

This paper reports the results of a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the basic Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by … network has a "star" structure.
