Abstract: Small businesses have long supplied a disproportionate share of major innovations in the United States. We review a centerpiece policy on this topic: the US Small Business Innovation Research (SBIR) program. We trace its legislative history and summarize program evaluations over the past 4 decades. Using newly matched data on SBIR awards and venture capital investments into small businesses, we show that despite often being compared with venture-backed businesses, SBIR-backed businesses pursue very different strategies. We use simple economic theories to motivate the SBIR program as a vehicle for the government to invest in small-scale, well-defined, but risky technologies that have large externalities, and we highlight a number of case studies consistent with this framework. Because the motivating friction lies at the level of ideas, our perspective encourages future evaluations to determine how the SBIR program influences not just who does the inventing, but what gets invented. Looking forward, we discuss how rising industrial concentration and the diffusion of artificial intelligence may reshape the program’s comparative advantage in the innovation policy tool kit.
