Krugman's Is Free Trade Passe?

In the ten years before the article "Secrets of Free Trade", Krugman said that international trade theory is fundamental change from constant-income and perfect competition tradition, including emphasis on increased revenue and incomplete competition He wrote that he experienced. New model (1987, 131 pages). Comparative advantage is no longer accepted as a general way to explain what actually happens in trade. External factors, on the other hand, suggest that free trade may not be the best interest for individual countries.

"Free trade is not outdated, but this idea has lost without losing its innocence" (Krugman, 1987, p. 132). Paul Krugman wrote in a close paper on free trade that classical trade theory was replaced by new trade theory. Traditional trade theory is driven by comparative advantage and is based on continuous scale 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. There are many assumptions about the comparative advantage theory, one of which is constant revenue, which is a traditional international trade model.

Krugman, 10 years before his article "The Secret of Free Trade", international trade theory focuses on the increase in revenue and imperfect competition, such as fundamental change from the tradition of continuous revenue and perfect competition He wrote that he did. New model (1987, 131 pages). Comparative advantage is no longer accepted as a general way to explain what actually happens in trade. External factors, on the other hand, suggest that free trade may not be the best interest for individual countries.

This is not a fundamental position on trade - it is economics of textbooks. Paul Krugman, a Nobel laureate economist and columnist at the New York Times, said that the Japan-ROK free trade agreement could promote economic recovery by focusing on trade agreements on average "money laundering" (Krugman , 2010). Specifically, from the perspective of macroeconomics, the US has too little expenditure on goods and services produced domestically, and total expenditure (Y) is defined as follows. Trade agreements bring higher X, but they also wrote those that bring higher M. As exports support demand for domestic products, employment will increase as X is higher. However, the increase in imports reduced the demand for domestic products, thereby reducing domestic employment. Table 5 shows the changes in China's imports and exports from 2001 to 2011 and their impact on total employment in the United States.
