Abstract

A method to measure yield risk associated with new technologies based on the concept of stochastic production and the method of moments. is demonstrated. The method is applied to measure mean and variance of some new technologies introduced in Cameroon in 1986-89 under the SAFGRAD Project. Data used for the study include a long time series for weather and a short cross-sectional/time series for yield-weather-technology relationships.
