In a recent paper, Tramontana (Economic Modelling, 27; 350–357, 2010) investigates the stability properties of a Cournot Duopoly game when the demand function is isoelastic. In this note, we show that for some well known applications of two-stage Cournot games (D. Aspremont and Jacquemin,...

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...

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...
