| Abstract: |
This paper studies the impact of collaboration on research output. First, we
build a micro founded model for scientific knowledge production, where
collaboration between researchers is represented by a bipartite network. The
equilibrium of the game incorporates both the complementarity effect between
collaborating researchers and the substitutability effect between concurrent
projects of the same researcher. Next, we develop a Bayesian MCMC procedure to
estimate the structural parameters, taking into account the endogenous
matching of researchers and projects. Finally, we illustrate the empirical
relevance of the model by analyzing the coauthorship network of economists
registered in the RePEc Author Service. |
