More false info derived from a false premise eh dizzy?
Myth 2. Free trade doesn’t lead to better economic outcomes in the real world.
Paul Krugman once quipped, “If there were an Economist's Creed, it would surely contain the affirmations 'I understand the Principle of Comparative Advantage' and 'I advocate Free Trade.'" However,
critics of free trade, such as development economist Ha Joon Chang, have made very odd statements such as this one:
There is a respectable historical case for tariff protection for industries that are not yet profitable. … By contrast, free trade works well only in the fantasy theoretical world of perfect competition.
Comments like these are puzzling because proponents of free trade don’t assume there is perfect competition. They simply recognize that if one country can produce a product at a lower opportunity cost than another, trade between the countries (or individuals) is mutually beneficial. (This is known as the theory of comparative advantage.)
Economists have examined countless times whether or not freer trade leads to greater economic growth. In regard to trade liberalization — reform that lowers barriers to international trade — the evidence consistently shows that
such reforms improve economic performance over time.
According to one study that examined 141 trade liberalizations and compared
economic performance before and after liberalization (after controlling for confounding factors), “Per capita growth of countries [after]liberalization was some 1.5 percentage points higher than before liberalization, and investment rates were 1.5–2.0 percentage points higher.”
Subsequent
research from Antoni Estevadeordal and Alan M. Taylor took the analysis further by comparing growth rates before and after 1990, when a wave of trade liberalizations occurred. The economists divided countries into an experimental group (the countries that liberalized trade regimes) and a control group (those that did not). According to a summary of their research, the authors “find strong evidence that
liberalizing tariffs on imported capital and intermediate goods raised growth rates by about one percentage point annually in the liberalizing countries.” Research has also shown that trade liberalization has caused greater economic performance in sub-Saharan Africa, a region desperately in need of growth.
Reforms that result in freer trade generally lead to superior economic outcomes. This is a well-documented observation. Although there may be situations in which freer trade is undesirable, these situations are not the norm, and
free trade policies are still the “reasonable rule of thumb,” as Paul Krugman has put it.
