For more than 35 years the United States has offered assistance to workers
displaced as a result of freer trade. The rationale lies in the welfare eco
nomics argument for compensation of those who lose from a shift in policy t
o meet broader social interests. The programme has failed to compensate ful
ly for adjustment costs, of course, and the originally enthusiastic support
of workers has given way to scepticism. Politics lie at the heart of the p
rogramme's origins, and institutional inertia is key to its longevity, the
author argues.
