Rules of Origin in North-South Preferential Trading Arrangements with an Application to NAFTA

Abstract

All preferential trading agreements (PTAs) short of a customs union use Rules of Origin (RoO) to prevent trade deflection. RoO raise production costs and create administrative costs. This Paper argues that in the case of the recent wave of North-South PTAs, the presence of RoO virtually limits the market access that these PTAs confer to the Southern partners. In the case of NAFTA, it is estimated that up to 40% of Mexico's preferential access to the US market in 2000 (estimated at 5%) was absorbed by RoO-related administrative costs with non-administrative costs for Mexican firms of about 3% US of import value. These findings are coherent with the view that North-South PTAs could well be viewed like a principal-agent problem in which the Southern partners are just about left on their participation constraint.
