“…We focus on development of new irrigation technologies through deliberate research by government agencies, academics, and irrigation enterprises to resolve regional problems. As a factor of production (IW in this case) becomes increasingly scarce (more costly) and government agencies subsidize the cost of adopting more-efficient irrigation technologies, irrigation enterprises allocate more R&D resources to developing technologies that save or substitute for the scarce resource (Hayami and Ruttan 1985, Kamien and Schwartz 1978, Kim et al 1996). We do not distinguish between public and private research as the efforts are often collaborative (Center for Irrigation Technology 2015, Irrigation Association 2015, Irrigation Technology Center 2015).…”
