This document, titled "Adoption of Agricultural Innovations in Developing Countries: A Survey," is a comprehensive review of the literature on the adoption of agricultural innovations in developing countries. The paper, authored by Gershon Feder, Richard E. Just, and David Zilberman, aims to explain the observed patterns of adoption behavior both theoretically and empirically. It begins with an introduction that highlights the importance of technological innovations in agriculture for increasing production and income in less-developed countries (LDCs), while acknowledging the challenges in rapid adoption due to factors such as credit constraints, limited access to information, and inadequate farm size. The paper then surveys various models of adoption behavior, including static and dynamic models, and discusses the analytical framework for understanding adoption processes. It reviews empirical studies that have attempted to clarify and validate adoption processes, focusing on factors such as farm size, risk and uncertainty, human capital, labor availability, credit constraints, tenure, and supply constraints. The paper also evaluates methodologies and models used in empirical research and suggests new approaches for future studies. The empirical studies reviewed cover a wide range of topics, including the adoption of high-yielding varieties (HYVs), fertilizers, irrigation, and other modern technologies. The paper highlights generalizations from the Green Revolution, noting that HYVs were adopted rapidly in areas where they were technically and economically superior, and that farm size and tenure did not significantly hinder adoption. However, it also acknowledges exceptions and the influence of different economic, social, and political institutions. The paper concludes by discussing the implications of the survey for further research on adoption processes, emphasizing the need for a better understanding of the interdependence among adoption decisions and the development of appropriate models for simultaneous adoption.This document, titled "Adoption of Agricultural Innovations in Developing Countries: A Survey," is a comprehensive review of the literature on the adoption of agricultural innovations in developing countries.
