对于贸易自由化对进口的影响，贸易理论家的估计少得令人惊讶，这让他们继续感到困惑。对这个谜题的所有解释都认为贸易自由化是既定的。但贸易保护水平并不是外生性的。内生保护理论预测，更高水平的进口渗透将导致更大的保护。本文发现，当贸易保护被内生建模时，其对进口的限制性影响很大，是外生保护的10倍。
Trade theorists continue to puzzle over their surprisingly small estimates of the impact of trade liberalization on imports. All explanations of the puzzle treat trade liberalization as a given. But the level of trade protection is not exogenous. The theory of endogenous protection predicts that higher levels of import penetration will lead to greater protection. This paper finds that when trade protection is modeled endogenously, its restrictive impact on imports is large, 10 times the size obtained from treating protection exogenously.
