The welfare impact of policy interventions in the foodgrain markets in Bangladesh

The paper attempts to estimate the welfare impact of different policy interventions in the foodgrain markets in Bangladesh using an economic surplus approach. Over the period of analysis, 1980-2003, the loss in consumer surplus exceeded the gain in producer surplus plus the gain in government revenue. Therefore, the interventions resulted in a deadweight welfare loss for society. In contrast, in the policy of liberalization, the gain in consumer surplus and in government revenue is larger than the loss in producer surplus, producing a net welfare gain to society
