An argument can be made for public support of pre-commercial research and development (R&D) when private industry, acting in response to market incentives, underinvests in socially desireable projects.

The Alternative Agriculture Research and Commercialization (AARC) Center was mandated by Congress to support pre-commercial R&D in new uses of agricultural commodities. This article develops a three-phase scoring model to evaluate and prioritize AARC Center proposals.
