In the article, "Is Free Trade Passé," Paul Krugman summarizes and
explains research that challenges, and presents alternatives to, the
assumptions of classical trade theory based on comparative advantage. In
a 4-6 page paper (12-point font, double-spaced) summarize positions
that challenge the assumptions of constant returns and perfect
competition (keeping in mind that empirical validation of trade theory
requires only reasonable approximations to these conditions) and discuss
the implications for classical trade optimism (the argument that free
trade is always "a good thing") and for trade policy and practice.
