A Global Perspective on Regional Integration in North America Thomas W. Hertel Director Center for Global Trade Analysis Purdue University
Outline • Comment on ERS trade flows study • Outline determinants of regional trade flows • Isolate those likely influenced by NAFTA • Propose alternative measure of regional integration • Compare across countries and sectors • Summary and report card
ERS Trade Flow Study • Gehlhar’s work is critical input: IBAT • Growth in bilateral agr flows accelerated, but doesn’t coincide with FTA’s: • US-CN since mid-80’s • CN-US early 90’s • MX-US from mid-80’s • Importance of macro-forces: • Mexican recession in 1995 • Asian financial crisis • How to disentangle these different factors?
Determinants of Trade Shares xshrcr = gdpshrr * opennessr * compositioncr* transcostcr Share of country c’s exports to region r depends on: - relative size of region r’s market - openness of r, relative to world - composition of c’s exports vs. r’s imports - relative transactions costs of exporting from c to r NAFTA is most likely to affect transactions costs.
Determinants of Trade Shares I will look at the combination of the last two terms: xshrcr = gdpshrr * opennessr * Icr where Icr = compositioncr* transcostcr = intensity of exports from c to r. Canceling out GDP and dividing: Icr = xshrcr / mshrr where mshrr = share of region r in world imports, net of c Logic: Compare c’s propensity to export to r with the rest of the world’s exports to r. If no geographic bias, then this will equal one. Regional agreements aim to boost this index.
An example • Consider the case of Mexican manufactured food exports to NAFTA • Export share has fallen from 90% in 1965 to 70% in 1995 • However, NAFTA’s share of world imports of food products (net of Mexico) has also declined • Export intensity has actually risen! • Global perspective is key

Conclusions • Trade shares offer flawed measure of integration due to country size and openness • Comparison to world imports changes view of integration (e.g., Mexican food exports) • Intensity of trade in farm and food products low in 1960’s and 70’s. Sharp rise from mid-80’s, now exceeds mnfcs! • FTA’s have surely contributed to this success in regional integration • Proof awaits more thorough analysis
