The Sensitivity of Strategic and Corrective R&D Policy in Battles for Monopoly.

The authors characterize the role for R&D subsidies in export markets where R&D is an uncertain process and the winner of the R&D competition monopolizes the market. Investments are assumed to induce either first order or mean-preserving second order shifts in the distribution of a firm's costs or, reinterpreting the model as a patent race, a firm's discovery dates. The authors show that, regardless of which form the uncertainty takes, a national strategic incentive to subsidize R&D exists but must be balanced against a national corrective incentive to tax R&D whenever a country has multiple firms involved in the R&D competition.
