We consider a model where each individual (or ethnic minority) is embedded in a network of relationships and decides … assimilation norms may emerge in steady state depending on the structure of the network. We then consider the role of cultural and …

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can … maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors … possibly overlapping projects. We bring our model to the data by analyzing the coauthorship network of economists registered in …

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 … frictions and the wage mechanism are in general not independent. The wage mechanism determines both the distribution of networks …
