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 spillovers can mutually promote dynamic competition at the industry level and how they
constitute a major source of growth in the economy. In the dynamic general equilibrium model that we propose, the representative
industry is a duopoly that consists of a leader who innovates and a laggard who freerides by exploiting the source of intraindustry
spillover. The main results show that the innovation strategies of the two firms can be dynamically strategic complements
if a large technology gap prevails and that a fall in the level of technological protection can enhance economic growth.

A typical assumption in the game-theoretic literature on research and development (R&D) is that all firms belonging to the
industry under investigation pursue R&D activities. In this paper, we assume that the industry is composed of two groups;
the first (the investors) is made of firms that have R&D facilities and are involved in this type of activity. The second
group corresponds to firms that are inactive in R&D (the surfers). The latter group benefits from its competitors’ R&D efforts,
thanks to involuntary spillovers. This division of the industry is in line with actual practice, where indeed not all firms
are engaged in costly and risky R&D. We adopt a two-stage game formalism where, in the first stage investors decide on their
levels of investment in R&D, and in the second stage all firms compete à la Cournot in the product market. We characterize
and analyze the unique subgame perfect Nash equilibrium.
