Conclusions about optimal R&D policies in existing endogenous growth models rely on strong assumptions regarding market structure. In particular, a single monopoly dominates each industry in most models or firms are cast as monopolistic competitors. A model which combines the endogenous growth framework with a single industry model of industrial dynamics is proposed to allow for multiple firms in each industry. Key features of competition through R&D typically missing in most endogenous growth models are introduced, including: (1) non-degenerate entry and exit; (2) distribution of firm sizes; and (3) turnover rates and rank reversals. The first chapter presents a single industry demonstrating how growth-promoting R&D subsidies alter the endogenously determined market structure. The second chapter presents a general equilibrium model of R&D based growth. Firms compete for market share through process R&D endogenously determining the market structure within and across industries. Endogeneity of the market structure allows for analysis of changes in the moments of the firm size distribution in response to policy. The chapter also presents the effects of an R&D subsidy for the entire economy. The long-run growth rate increases with the subsidy. However, it also increases the concentration level across the economy offsetting the welfare gains to faster growth
