R&D spillovers, concentration and market performance

In a two-stage R&D game of process innovation, we investigate the effect of exogenously changing R&D spillovers and market concentration on the equilibrium level of effective cost reduction, total output, profits and social welfare. Interpreting spillover as a measure of patent protection, we find that weaker patent protection results in less R&D. We also show that firms prefer weaker patent protection, but social welfare is maximized for higher levels of patent protection. In terms of market concentration we show that firm profits decrease with increasing numbers of firms. Social welfare is typically maximized under oligopoly with the optimal number of firms depending on the level of spillover and efficiency of R&D investment.
