Preferential Trade Agreements Vs. Multilateralism: In The New Trump-World, Does Canada Face An Impossible Choice?

International trade is often framed in starkly divergent terms: either economies choose multilateral trade agreements (MTAs) and advance the cause of global economic liberalization, or they choose preferential trade agreements (PTAs) and put the entire system at risk. Canada has a long track record of pursuing PTAs and with the Trump administration’s opposition to multilateralism, and longstanding opposition in elements of the Republican and Democratic parties, this trend will likely continue. The question is whether progress will come at the expense of the global trade system.

Some economists believe PTAs to be trade-diverting, reducing trade with more efficient producers outside the agreement. Others insist that PTAs can create trade by shifting production to lower-cost producers in one of the participating economies. One prominent contrary argument holds that PTAs lead to discontinuities in tariff regimes between economies and regions, increasing transaction costs, disrupting supply chains, creating opportunities for corruption and harming global welfare, especially in developing economies.

While debate continues about the effects of PTAs, a closer examination suggests that worries are overblown about their negative impacts on global trade flows. Evidence indicates that they support rather than harm the international trading system. Economies shut out of PTAs are more motivated to seek out agreements in new markets, increasing liberalization overall. They may also seek a reduction in most-favoured nation (MFN) tariffs, which would deprive PTAs of their major tariff benefits. Studies have found complementarity between preferential and MFN tariffs, revealing that PTAs promote external trade liberalization. Even if a PTA reduces a given economy’s incentive to push for multilateral liberalization, it raises the odds of that economy’s liberalizing its trade to avoid getting left behind.

PTAs are a response to the difficulties of securing sweeping multilateral agreements. The World Trade Organization (WTO) Agreements authorize them under GATT Article XXIV, GATS Article V, and the enabling clause, and the WTO facilitates a degree of governance over PTAs through its dispute settlement process. Over the past 25 years, economies have adopted these deals at a rapid pace. Between 1994 and 2005, the number of PTAs increased from 50 to 200. By April 2018, 336 were in effect. At the same time, global trade has increased significantly. Between 1994 and 2010, the volume of world merchandise exports more than doubled. The proliferation of PTAs has resulted in a rise in international trade governance, because the economies involved shape their relationships in line with the WTO agreements. This juridification makes PTAs subordinate to the international system rather than giving them room to dissolve it. Canada should therefore have no fear of pursuing PTAs within the larger framework of the effort to achieve multilateral trade liberalization.
