Fact of the Week: US Innovative Firms Operate in Too Few Markets Relative to the Social Optimum
Source: Craig A. Chikis, et al, “The Geography of Innovative Firms,” (working paper 34010, National Bureau of Economic Research, Cambridge, Massachusetts, July 2025).
Commentary: The spread of U.S. firms that engage in research and development (R&D) can facilitate the spillover of knowledge to surrounding firms and innovators. Therefore, the location decisions of firms can impact the aggregate innovation and economic growth of a region. There are negative consequences for firms that do not operate in enough local markets, as well as for firms that operate in too many, as excessive expansion can result in labor shortages and weakened productivity. Research from Craig A. Chikis et al., finds that innovative U.S. firms, or those that engage in high levels of R&D to develop new products or services, in the aggregate, operate in too few markets relative to the social optimum, thus resulting in less knowledge spillover. To promote greater expansion from R&D conducting firms, U.S. policymakers should prioritize policies promoting spatial expansion. A spatial expansion subsidy that is proportional to firms’ expenditure on fixed plant costs would incentive the growth and spread of R&D conducting firms into new markets.
