This paper extends previous research on the effects of process imitation on economic growth by accounting for stochastic intra-industry spillovers. We employ a non-Schumpeterian growth model to determine the impact of such spillovers on investment in industries where firms are either...

This paper develops an R&D based endogenous growth model in which the firm’s free-riding behavior, prompted by an incomplete technological protection at the industry level, can drive economic growth. Unlike existing endogenous growth models, it shows how free-riding behavior and process...

This paper constructs an ex-ante asymmetric R&D Cournot differential game with knowledge spillovers. It shows that in the long-run equilibrium firms have incentives to innovate as long as the knowledge externalities are bidirectional. We also carry out a series of numerical simulations of the...

This article gives an example of an industry where process R&D is not deterred by a lack of Intellectual Property Rights (IPR). We observe that the imitation driven by this lack of IPR acts as a source of competitive pressure on the technological leader who responds by increasing its process...

This paper shows that innovation (or Schumpeter's) cycles can be demonstrated in a discrete and finite dynamic game of innovation and imitation. We find that the cycles depend crucially on whether imitation is a credible threat and hence, we conclude that strategic interactions are sufficient to...
