INTERPAKS, Berkeley, CA: Giannini Foundation of Agricultural Economics, University of California, 1982. (Working paper no. 227). 37 p., Examines the role of farm size and technology adoption in developing countries under risk aversion. Develops a local mean variance approximation of expected utility based on farmers' individual wealth. This approximation is used to examine how technology adoption differs among farms of different size depending upon risk considerations. Produces a model illustrating the dependence of technology adoption behavior on risk aversion and indirectly on wealth (farm size) tractable for empirical purposes.
