Price distortions in developing countries: A bias against agriculture
评估了发展中国家政府干预农产品市场的效果，发现农业部门常被重税，导致生产受抑、消费受补，政府收入增加但外汇收入减少。
This article evaluates the effects of government intervention in agricultural commodity markets for a sample of developing countries. It also presents a review of the methodology for quantifying the effects of the distortions on prices, supply, demand, incomes, and foreign exchange. The empirical results indicate that the agricultural sector in developing countries is often heavily taxed. As a consequence, agricultural production is discouraged, while consumption is subsidized, and the increases in government revenue provided by taxation are counterbalanced by a loss of foreign exchange earnings.
