This paper investigates the nature of competition in the rice market at district level, and measures the degree of integration in ten selected rice markets in Bangladesh. It also assesses the effects of price stabilization schemes on producers, consumers and government revenue. Analysis by correlation method of 1972-87 wholesale and retail price data reflects association among the selected district markets. Application of the Ravallion approach indicates that the central market price exhibits price leadership over the other local markets. The results also indicate the presence of long run market integration. Test results, however, do not provide evidence of market segmentation and local market characteristics. Granger causality tests indicate the existence of a unidirectional and instantaneous relationship of the central market with the local ones. The standard partial equilibrium approach was used to evaluate the impact of government intervention on the rice market. Various parameters such as welfare gain of the producers and consumers, changes in government revenue and the foreign exchange bill were estimated. The results indicate that government intervention mostly benefitted consumers, and did not provide sufficient incentives for food grain production.
