2) discuss the issue of intra-industry trade as follows: “In particular, countries should export goods whose factor content reflects their underlying resources. This is in fact by and large true of countries’ net exports. But to casual observation, Helpman and Krugman (1985), where industry productivity remains constant and, depending on the value of ﬁxed and variable trade costs, either all or no ﬁrms export following trade liberalization. They differ from existing heterogeneous-ﬁrm models such as Melitz (2003) by tition `a la Dixit-Stiglitz-Krugman (Krugman 1979, 1980, 1981; Dixit and Norman 1980; Helpman and Krugman 1985) provides an elegant account of intra-industry trade and plays a major role in the recent literature.1 In his inﬂuential survey, Matsuyama (1995, p.
