The studies necessarily ignore the tradeoff between foreign aid and tariff reductions; if the former reduces pressure for the latter, the net effect of the aid on the recipient nations could be negative.

• 这些研究不可避免地忽略了对外援助和关税减免之间的利弊权衡问题；如若前者可以减轻后者所受的压力的话（指由于捐助国的对外援助，可使对其关税减免的呼声减弱，压力减小），这种援助对受助国的影响最终将会是消极的，负面的。
