Does ‘Protection for Sale’ Apply to the US Food Industries?
检验“保护待售”模型在美国食品加工业中的适用性，发现模型预测成立，且国内福利权重低至0.837，表明保护确实可被购买。
Abstract This paper tests the Protection for Sale model in terms of the structure of protection and how realistic the estimated domestic welfare weight is relative to campaign contributions. Using data from US food manufacturing, empirical results support the key predictions for the structure of protection when either all food manufacturing industries or most of the general population is assumed to be politically organised. The domestic welfare weight is estimated as low as 0.837, the lowest econometric estimate to date, underlining that protection is for sale and that, with a qualified ‘yes’, the model fits the data for these industries.
