Redistribution of social benefits from advances in extension and research in the Tanzanian maize industry
研究了坦桑尼亚玉米产业推广和研究进步对消费者和生产者福利的影响，发现市场剩余比例不同时福利分配差异显著，并据此提出资助玉米研究和推广的税收方案。
This study determined consumer and producer welfare gains from advances in extension and research in the maize industry of Tanzania to determine how a national taxing schedule should be determined. It was found that, for an off-farm marketable surplus of 40%, consumers and producers gain equally, while for an off-farm marketable surplus of 60%, consumers realize 75% of the welfare benefits. This suggests that consumers and producers should share equally in a revenue generating tax for funding maize research and extension programs. However, for large producers with a marketable surplus of 60% or more, their tax should decrease proportionally to the amount sold. Alternatively, if taxed equally, large-scale producers should receive some form of compensation through direct government payments. ©1999 Elsevier Science B.V. All rights reserved.
