Today's issue of The Wall Street Journal has an interesting little story (free content at this writing) about how a 46-year old tariff spat has an auto company (Ford) partially dismantling imported vehicles to avoid a stiff tariff. The result is almost laughable. (I especially enjoyed the auto exec who claimed "we're free trade." But I won't pursue that.)
The dead-weight loss is very clear. And, as a colleague of mine points out, it can even be used to illustrate the "broken window" fallacy of job-creation.
I hope you enjoy it.
