Identifying Changes in Productivity and Risk among Malagasy Rice Farmers We thank Eliane Ralison for data entry assistance and Bart Minten, Erick Fernandes, David Just, Glenn Lines, Jean Claude Randrianarisoa, Mattia Romani, Norman Uphoff, T.J. Wyatt, two anonymous referees, and seminar participants at Cornell University and the 2003 AAEA annual meetings for helpful discussions and comments on preliminary results. This research was supported by USAID under the Programme Ilo cooperative agreement from the Madagascar mission, number 687-00-00-00093-00, the BASIS CRSP, through grant LAG-A-00-96-90016-00, and the SAGA cooperative agreement, number HFM-A-00-01-00132-00.

Copyright 2004 American Agricultural Economics Association KEYWORDS Madagascar • rice • SRI • technology adoption • yields ABSTRACTWe introduce a method for properly attributing observed productivity and risk changes among new production methods, farmers, and plots by controlling for farmer and plot heterogeneity. Results from Madagascar show that the new system of rice intensification (SRI) is indeed a superior technology. Although about half of the observed productivity gains appear due to farmer characteristics rather than SRI itself, the technology generates the estimated average output gains of more than 84%. The increased estimated yield risk associated with SRI would nonetheless make it unattractive to many farmers within the standard range of relative risk aversion.
