Rice demand in Tanzania: an empirical analysis
利用家庭消费调查数据，估计了坦桑尼亚进口大米、国产大米和玉米的价格与支出弹性，发现消费者偏好国产大米，进口与国产大米替代性弱。
Abstract We investigate the consumer side of the Tanzania rice market with the primary objective of estimating price elasticities of imported and domestically produced rice. Previous studies of the rice market in Tanzania claim that domestic rice is implicitly protected by consumer preference of its perceived better quality. However, rice producers increasingly complain that imported rice adversely impacts the price of domestic rice. Using household consumer survey data, we estimate price and expenditure elasticities of imported rice, domestic rice, and maize to assess their substitutability in the Tanzanian diet. Our results show that Tanzanian consumers have a preference for domestic rice varieties with weak substitutability between domestic and imported rice varieties.
