简述：
We study the distributional consequences of trade in a world with two industries and two
heterogeneous factors of production. Productivity in each production unit reáects the ability of
the manager and the abilities of the workers, with complementarity between the two. We begin
by examining the forces that govern the sorting of worker and manager types to industries, and
the matching of workers and managers within industries. We then consider how changes in
relative output prices generated by changes in the trading environment a§ect sorting, matching,
and the distributions of wages and salaries. We distinguish three mechanisms that govern the
e§ects of trade on income distribution: trade increases demand for all types of the factor used
intensively in the export sector; trade beneÖts those types of a factor that have a comparative
advantage in the export sector; and trade induces a re-matching of workers and managers within
both sectors, which beneÖts the more able types of the factor that achieves improved matches.
