Advisory No. 192

DR-CAFTA DESERVES HOUSE SUPPORT

The House of Representatives is to vote this
week on the free trade agreement with the
Dominican Republic and five Central American
nations (DR-CAFTA). The vote is expected to be
very close. Perhaps a reminder of why trade is
beneficial is in order.
Trade enables people to generate more goods
and services with the resources that are available.
It increases the productivity and efficiency of the
participants. How? Trade lets people specialize in
the production of what they do relatively well,
increasing their output. They can then swap some
of their increased output for products they have
more difficulty making, obtaining those items from
other people who do relatively well producing them.
Everyone can produce more than before, and
exchange the output to make them all better off.
Trade does not depend on one group of people
being absolutely more efficient (having an absolute

advantage) making one set of products, and another
group of people being absolutely more efficient
making another set of products. Trade can occur,
and can enhance living standards, even if one region
is more efficient at everything than another. All it
takes for trade to be beneficial is for one region's
relative efficiency in producing the two sets of
goods to differ from the other region's relative
efficiency in producing the two sets of goods.
These   differences  are  called  comparative
advantage.
The classic example in the economic textbooks
(see table) is a world consisting of two countries,
Britain and Portugal, and two products, wine and
textiles. Assume that workers in Britain are more
efficient at producing both products, but that their
efficiency edge in making cloth (9 to 1) is even
greater than their edge in making wine (3 to 2). If
so, it will benefit workers in both countries for
Britain to reduce its output of wine and raise its

Gains from specialization and trade
Units of output         Potential change from
per worker per day           specialization
Country                     Textiles       Wine         Textiles      Wine
Britain                       9             3             +9           -3
Portugal                       1            2             -3           +6
Combined change in output                                 +6           +3
Change in production if Britain shifts one worker from  wine to textile production, and Portugal shifts 3
workers from textile to wine production. (Adapted from James D. Gwartney, Richard L. Stroup, and
Russell Sobel, Economics: Private and Public Choice, 9th edition, exhibit 17-2, p. 437.)
