Free Trade and Costly Love

LONDON – The World Trade Organization’s ministerial conference in Bali in December produced a modest package of encouragements to global trade. More broadly, the WTO’s multilateral approach has shown its worth by preventing a massive increase in trade barriers, unlike in 1929-1930, when protectionism helped deepen and broaden the Great Depression. But the main question – whether globalization is a good thing, and for whom – remains unanswered.

The essence of globalization – free trade – rests on the theory of comparative advantage, which views international trade as profitable even for a country that can produce every commodity more cheaply (in terms of labor or all resources) than any other country.
