Protection for Sale: An Empirical Investigation
检验了Grossman-Helpman“保护待售”模型对美国1983年进口保护模式的预测能力，发现模型与数据基本一致，且政府目标函数中社会福利权重远大于政治献金权重。
The Grossman-Helpman “Protection for Sale” model, concerning the political economy of trade protection, yields clear predictions for the cross-sectional structure of import barriers. Our objective is to check whether the predictions of the Grossman-Helpman model are consistent with the data and, if the model finds support, to estimate its key structural parameters. We find that the pattern of protection in the United States in 1983 is broadly consistent with the predictions of the model. A surprising finding is that the weight of welfare in the government's objective function is many times larger than the weight of contributions.
