We analyze the endogenous formation of R&D networks, where firms are active in different product markets and can benefit from R&D spillovers form collaborating firms within or across different industries. R&D spillovers help firms to introduce process innovations to lower their production costs....

In this paper we study the coevolutionary dynamics of knowledge creation, diffusion and the formation of R&D collaboration networks. Differently to previous works, knowledge is not treated as an abstract scalar variable but represented by a portfolio of ideas that changes over time through...

We study production networks where firms' products can be described by a set of input and output characteristics, and links are formed only if the output characteristics of a seller match the input characteristics of a customer. We introduce a fully endogenous network formation model with...

We analyze binary choice models in communication networks, in which both, the formation of links in the network as well as the action choices are endogenous. We provide a complete characterization of the equilibrium action choices and networks, where agents choose their strategies - actions and...

In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors in the network benefit from each other's action levels through local complementarities and there exists a global interaction effect reflecting a strategic substitutability in...

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 but also to researchers indirectly linked to them....
