α: calibrated so average coauthorship-adjusted count equals average raw count
We consider a general equilibrium model in which the production sector may exhibit incresing returns to scale or more general types of nonconvexities. We assume that the firms follow general pricing rules. Under standard assumptions in this model, we establish an index formula, which generalizes similar results on exchange economies and on convex production economies. This formula allows us to deduce an equilibrium existence theorem and a uniqueness condition.
