摘要:
The Spencer-Brander argument for strategic R&D policy (Review of Economic Studies, 1983, 50, 702-722) is re-examined within an intertemporal model of stochastic innovation. It is shown that an optimal policy is independent of the choice of strategic variables in product market competition but sensitive to the appropriability of the new technology. At low or high degrees of appropriability R&D taxes are an optimal policy but at intermediate degrees R&D subsidies may be optimal. The paper explains why these results differ from Bagwell and Staiger's finding (International Economic Review:, 1992, 33, 795-816; Journal of International Economics, 1994, 36, 133-150) that R&D subsidies are an optimal policy in the presence of uncertainty.
