I am the Xerox Professor of Economics at the University
of Rochester. My field is international economics and
most of my research has been on the pure theory of international
trade. Early papers have tended to concentrate on developing
a set of small-scale competitive trade models in a general
equilibrium context. More recently attention has shifted
to trade theory in which some inputs into the production
process, or primary factors such as labor, are traded
or mobile in world markets. My recent book for M.I.T.
Press, Globalization and the Theory of Input Trade,
(2000), summarizes much of this work, including a discussion
of the tendency recently in world markets for firms
to outsource fragments of the production process to
other parts of the globe where factor prices (especially
wage rates) give a better match with input requirements.
I am joint author of a textbook in the international
area, World Trade and Payments, (joint with Richard
E. Caves and Jeffrey A. Frankel), (Addison Wesley),
now in its 9th edition.
