Free Trade And NAFTA

Non-economists often debate the merits of free trade and/or NAFTA. But if you ask economists, they are nearly unanimously in agreement in favor of both:

None of the economists surveyed disagreed that the gains to freer trade are much larger than any costs. And only two economists even said that the answer is uncertain. In a space for additional comments, MIT’s Richard Schmalensee declared “If that’s not right, almost all of economics is wrong”.

Economists have emphasized the benefits of free trade for a long time, reflecting the field’s belief in the importance of specialization, comparative advantage, and gains from trade. Indeed, these results are similar to other surveys that show economists strongly supporting free trade.

So why do pundits and voters lag economists in supporting free trade? In his excellent book The Myth of the Rational Voter, Bryan Caplan provides evidence that people suffer from a handful of systematic biases that influence their beliefs, and three of these can help explain why voters are skeptical of trade: anti-market bias, anti-foreign bias, and pessimism bias.
