We propose a dynamic model in which firms compete to produce sequential and cumulative innovations, and in which the more firms do research in one sector the more likely it is that one of them innovates. Firms choose research effort and whether to patent innovations or to use an Open Source...

This paper introduces time inconsistent preferences into a moral hazard setting where the agent is risk-averse. We derive a necessary optimality condition on the consumption allocation that is different from the so-called Inverse Euler Equation of Rogerson (1985). Specifically, inverse marginal...

This paper examines a three-stage model of divisionalization where, first, two parentfirms create independent units, second, the parent firms allocate cost reduction levelsover these units, and third, the resulting units compete in a Cournot market given theircurrent costs of production. The...

A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry outputconfigurations encompassing one limit-output dominant...

This paper examines a three-stage model of divisionalization where, first, two parent firms create independent units, second, the parent firms allocate cost reduction levels over these units, and third, the resulting units compete in a Cournotmarket given their current costs of production. The...

A duopoly model of cost reducing R&D-Cournot competition is extended to study the endogenous timing of R&D strategic investment. Under the assumption that R&D spillovers only flow from the R&D leader to the follower, sequential and simultaneous play at the R&D stage are compared, in order to...
