Abstract:
The paper explores the effects of economic integration on trade, wages, and welfare when market sizes differ. A duopoly model with two-way intraindustry trade in similar products and with unionized labor markets is employed. It is confirmed that, for a wide range of different relative market sizes, integration leads to higher wages, employment, and welfare. However, where market sizes differ widely, the reduction of trade barriers leads to a reduction of wages, employment, and-in some circumstances-welfare in the country with the large market.
