Última Agricultural R&D Lags from a Dual Perspective 31 Yao, Xiaojia; Andersen, Matthew A.. This study examines the role of public agricultural research and development (R&D) in the process of knowledge production and productivity growth in U.S. agriculture from a new perspective. The seminal work of Griliches (1967) established the relationship between investments in R&D, the process of knowledge production, and the productivity enhancing benefits they create. In the literature on estimating knowledge production functions measures of multi-factor productivity (MFP) are regressed against measures of knowledge stocks, thereby enabling the researcher to quantify the relationship between the stream of investment expenditures and the productivity enhancing benefits they produce. A critical aspect of this research involves how to handle...

Private R&D is a major source of innovation and productivity growth in agriculture worldwide. This paper examines trends and determinants of agricultural R&D in China. Results show that while the public sector monopolized agricultural research until recently, private agricultural R&D has grown rapidly since 2000, driven largely by agribusiness privatization. Public-sector R&D investments in basic research also encouraged private R&D research, but public investments in technology development crowded out private R&D investment. China’s private R&D investment would grow more rapidly if the government shifted public resources from technology development to basic research.

Ano: 2011 URL: http://purl.umn.edu/117213 Rates of Return to Public Agricultural Research in 48 U.S. States 31 Plastina, Alejandro S.; Fulginiti, Lilyan E.. The internal rate of return to public investment in agricultural R&D is estimated for each of the continental U.S. states. Theoretically, our contribution provides a way of obtaining the returns to a local public good using Rothbart’s concept of virtual prices. Empirically, we use the spatial dependency among states generated by knowledge spillovers to define the ‘appropriate’ jurisdiction. We estimate an average own-state rate of 17% and a social rate of 27%. These figures should inform the policy debate on the allocation of federal funds to research in anticipation of a possible global food crisis.
