Markusen and Melvin note that their condition can be found in various forms in Kemp and Negishi (1970), Markusen and Melvin (1981), and Helpman (1984). 1See, for example, Anderson (1979) , Helpman and Krugman (1985), Helpman (1987), Feenstra (2002), and Anderson and van Wincoop (2003). 2In the working paper that preceded the published version of their paper, Frankel and Romer (1996) used the same methodology to study the impact of openness on the rate of growth of income per capita. Product Di ﬀerentiation (Helpman and Krugman 1985) The CES utility function has proved very useful in models of product diﬀerentiation. The typical form of modeling prefer-ences is to assume an upper-tiered utility function u(x0,V)=U (x0,V(x1,,xn)) (5.1) where x0 is consumption of some homogeneous numeraire good, tional comparative advantage. Early papers include Lancaster (1980), Krugman (1979, 1981), Dixit and Norman (1980), Helpman (1981), and Ethier (1982); much of the positive theory is summarized in a common framework by Helpman and Krugman (1985).

Teorin behandlar informationsbarriärer som en viktig förklaring till handelsteorin, genom produktdifferentiering, skalfördelar och inslag av såväl monopolistisk konkurrens (Krugman och Helpman, 1985, Feenstra, Markusen.

The central idea is that a world with imperfect mobility of productive factors across regions or countries may replicate the essential equilibrium of a full y integrated economy provided that goods are perfectly mobile.
