Is Free Trade Passé?

"Free trade is not outdated, but this idea has lost its innocence so unrecoverably" (Krugman, 1987, p. 132). Paul Krugman wrote in a close paper on free trade that classical trade theory was replaced by new trade theory. Classical trade theory is driven by comparative advantage and is based on continuous size and complete competition, which supports free trade. This classical theory emphasizes that trade is caused by differences in the preferences, technologies and factors' benefits among countries (Krugman, 1987).

What is free trade? Free trade is international trade in goods and services without tariffs and other trade barriers. Krugman (1987) is looking for true free trade in IsFreeTradePassé depending on perfect competition and constant revenue. Today, each country tends to follow strategic trade policy, domestic companies, households, and production factors dominate over foreign companies, households and production factors. Although this approach supports the existence of trade rather than trade, it begins to shake free trade as the only answer to international economic theory. Therefore, government intervention does not always succeed, but it is now the standard of international trade. However, as Krugman pointed out, "In the world characterized by increased revenue and incomplete competition, budget constraints still exist.

This classical theory emphasizes that trade is caused by differences in the preferences, technologies and factors' benefits among countries (Krugman, 1987). However, the new international trade theory is promoted by an increase in returns to a scale also known as economies of scale, leading to incomplete competition (Carbaugh, 2011). In addition, this new trade theory, in contrast to free trade, encouraged governments to work hard to improve market outcomes for national interests.
