Application of a simulation model with over 100 equations to a specific underdeveloped economy to study growth prospects for a 25-year period, 1960 to 1985. Results of computer runs in the form of case "histories" were obtained and compared to determine the likely effects of several sets of conditions and policy alternatives on development objectives. Base case trends suggest that rates of population growth show a more rapid advance than the labor market or food production will be likely to take care of by 1980. Subsistence alone poses a threat that must be met with a massive, sustained national effort in all sectors. 340 pp. Ref.
