MARKETING IN DEVELOPING COUNTRIES Harold Riley and Michael Weber* Introduction Over the past two decades there has been a significant and growing involvement of U.S. agricultural economists in foreign assistance programs directed towards the less developed countries. Through programs financed by the U.S. Agency for International Development, foundations, foreign governments and multi-lateral international agencies, agricultural marketing economists have had opportunities to conduct research and to provide advisory inputs into the development of programs to improve marketing systems. Con- currently there has been an expanding flow of students from the less developed countries (LDCs) through the graduate programs of U.S. universities (1). In order to be effective in their roles as teachers, researchers and advisors economists have found it necessary to adapt their conceptual and analytical tools for use in different institutional, political and social environments. In some instances marketing problems confronted in the LDCs appear to be similar to those experienced in the U.S. some 50 to 75 years ago when agri- cultural and industrial changes began to transform the economy in a relatively rapid and irreversible manner. However, the economic, political and social conditions in the LDCs pose problems of market organization that require solutions carefully tailored to the needs of particular country situations. *We want to acknowledge valuable comments and suggestions on earlier drafts of this paper which were made by Emerson Babb at Purdue University, and Jim Shaffer and Mark Newman of Michigan State University.
