Why "Buy American" is a Bad Idea but Politicians still Like it

When the world economy was recently hit by a severe recession, governments all over the world reacted by initiating stimulus packages. Some countries (among them, most notably, China and the US) tried to put special emphasis on their home industries by including “Buy local” clauses into the stimulus package. By analyzing the dynamics of transitory changes of trade barriers as a short-run response to an economic downturn, we show that beggar-thy-neighbor policies do not work. We then come up with two rationales that help to understand why countries nevertheless consider protectionism to be a good response to a recession: (i) the lobbying of domestic, non-exporting firms, and (ii) the relationship between vulnerability, the degree of openness and loss aversion of consumers.
