Industrial Policy to Develop a Multi-Firm Industry
StatisticsView Usage Statistics
Governments face pressure to act when coordination and learning externalities block development of otherwise-profitable industries that would produce merit goods for the domestic market. A short-term subsidy that offsets these externalities could potentially jump-start a multi-firm industry, if the subsidy induces a pioneer firm to enter and then the pioneer's first-period output generates coordination and learning externalities. These externalities could induce subsequent entry by input suppliers and/or competitors. However, empirical evidence raises questions about the ability of governments to use short-term subsidies to jump-start new industries. We explore one explanation for the difficulty of jump-starting new industries: the subsidy could generate counter-productive incentives for the pioneer firm to prevent entry of additional firms. We model the jump-start strategy and examine whether coupling a short-term fixed subsidy with a per-unit subsidy can achieve the objective of creating a multi-firm industry.
