The effect of the Canada‐US Free Trade Agreement on Canadian multilateral trade liberalization
研究发现加美自由贸易协定的关税优惠导致加拿大在1989-1998年间平均关税下降2个百分点，且对美国出口租金少的行业关税削减幅度更大，但未发现优惠贸易自由化与游说活动有关。
Abstract In this paper show that the Canada‐US Free Trade Agreement (CUSFTA) tariff preferences have triggered a decline in Canadian external tariffs, explaining a two percentage point reduction in the average tariff between 1989 and 1998. Next, we found that industries that generate the least export rent to the US firms experienced deeper tariff cuts in Canada; this result provides evidence of cooperation in trade policies between the US and Canada. Finally, we estimate the effect of the CUSFTA on the intensity of industrial lobbying for trade policy in Canada and find no relationship between preferential trade liberalization and lobbying activity.
