The “export-import” effect and economic growth

Abstract

This paper proposes that singular improvements in productivity and growth are a result of increased exports and imports, especially in the manufacturing sector, but that sustainable increases in growth can only emerge through industrial diversification. Trade liberalizations between Canada and the United States have caused a narrowing of manufacturing productivity differentials, a predominance of intraindustry trade, and a positive Canadian trade balance for manufactured end products and fabricated materials. Sustained growth, however, relies more on the diversification of the industrial structure. Toward this end, Canadian trade policies should: (1) concentrate productivity in the exportable, rather than importable, sectors, (2) rationalize and specialize between rather than within industries, (3) encourage two-way trade in each industry, (4) liberalize trade gradually to avoid interindustry disruptions, and (5) redirect job real- location funds toward worker retraining and firm-specific modernization programs.
