This report summarizes several alternatives analyzed relative to Thailand's Fourth Five-Year Development Plan. The alternatives are analyzed relative to the agricultural sector.

The research summarized has been conducted in the Division of Agricultural Economics, Ministry of Agriculture and Cooperatives, Royal Thai Government under Director Somnuk Sriplung. It is a cooperative project on agricultural sector planning between the Division of Agricultural Economics, Ministry of Agriculture and Cooperatives, and the Center for Agricultural and Rural Development of Iowa State University. Earl 0. Heady serves as project director for Iowa State University. The cooperative project is financed by the Agency for International Development and the Royal Thai Government.

The report summarizes the alternatives analyzed and the results forthcoming from them for the year BE 2524 (1981). It does not provide documentation of the national and interregional linear programming model used in the analysis since the latter is being detailed in a separate publication. The national programming model, being used for various sector planning projects and policy analyses, is under continuing development.

This manuscript is written in cooperation with the following staff members of the Division of Agricultural Economics, Ministry of Agriculture and Cooperatives, and the Iowa State University Sector Analysis team. Major responsibility for writing fell on Charles F. Framingham while model development and application and data analysis were largely the responsibility of Arthur L. Stoecker and Kanak Khatikorn assisted by others of the DAE-ISU staff.
