Evaluating the Controversy between Free Trade and Protectionism

This chapter argues for economic free trade through the lens of trade theory. While free trade may not be optimal, many consider it to be the most pragmatic policy option for a country. During the 19th and 20th centuries, policymakers asked whether free trade was in everyone's best interest. The modern case for free trade argues that government intervention in trade is impractical. Free trade is not always the best policy choice when the objective is to maximize national welfare. Free trade is pragmatically, rather than technically, optimal because it is attainable and most likely to produce the highest level of economic efficiency.
