Beirut, Lebanon: International Center for Agricultural Research in the Dry Areas (ICARDA).https://hdl.handle.net/20.500.11766/66253The aim of this paper is to briefly introduce the production function and productivity index approaches used in the estimation of the returns to agricultural research. The paper, for the most part, summarizes Davis (1981) and Lu et. al., (1979). A list of production function type studies for various commodities and countries with, their associated rates of return are found in Ruttan (1982, pp. 242-246).
