A Statistics Canada study released this morning shows that free trade agreements provided economic benefits to all regions of Canada during the 1990s. The benefits were not spread evenly across the country, however: Ontario received the greatest economic gains.
The Canada-US Free Trade Agreement (FTA) was implemented in 1989, and the North American Free Trade Agreement (NAFTA) in 1994. The researchers examined data from 1980 through 1999 in order to quantify changes following the agreements.
The study found that all regions have benefited through improved productivity performance, higher wages and higher output growth. However, Ontario has been the principal beneficiary.
. . .
Some of these productivity gains were passed on to workers in the form of higher wages. Workers in Ontario gained the most from increased trade integration, while the gains in other regions, although significant, were relatively small.
The study found that from 1988 and [sic] 1999, increased trade integration was associated with real wage gains of 12.0% for manufacturing workers in Ontario, but only 1.0% in Quebec, 0.8% in Western Canada, and 0.4% in Atlantic Canada.
The study also contradicts a frequently expressed concern, namely, that free trade agreements with the United States would result in relocation of firms from Canada to the US, thus decreasing Canada's share of total North American production. To the contrary, the study found that all regions of Canada increased their share of North American manufacturing during the time period under study. Ontario saw by far the largest expansion in manufacturing share, followed by Quebec and the Prairies, while BC and the Atlantic region saw the smallest gains.
A summary of the study's findings is posted here and the full paper, by Wulong Gu and Gary D. Sawchuk of Statistics Canada's Micro-economic Analysis Division, is available here (pdf).
An additional point of interest is that the source of the economic model predicting losses for Canadian manufacturing under free trade is a 1980 article by Paul Krugman, Professor of Economics at Princeton University, now better known as an opinion columnist for the New York Times. Dr Krugman's columns often contain reflexive criticism of President George W Bush's foreign and domestic policies.
Krugman’s (1980) model of trade in differentiated goods with increasing returns to scale suggests that . . . a reduction in trade barriers or an increase in trade integration should be linked to a decline in Canada’s share of North American shipments as firms relocate to the larger U.S. market and serve the small Canadian market through exports. Such relocation allows firms to save on trade costs and realize economies of large-scale production. This potential loss in Canada’s share of North American shipments from increased trade integration has been an important concern for workers and policy makers in Canada.
The Statistics Canada paper puts forward results that contradict Krugman's trade model.
This evidence is at odds with Krugman’s model of trade with increasing returns.
. . .
Overall, our results stand in sharp contrast to Krugman (1980) . . . On the other hand, our results are consistent with those from Head and Ries (2001) who also find little support for Krugman’s model of trade with increasing returns.
