Conventional trade theory, which combines the Heckscher-Ohlin theory and the Stolper-Samuelson theorem, implies that expanded trade between developed and developing countries will increase wage equality in the former. This theory is widely applied. It serves as the basis for estimating the impact of trade on wages using two-sector simulation models and the net factor content of trade. It leads naturally to the presumption that the rapid growth and declining relative prices of US manufactured imports from developing countries since the 1990s have been a powerful source of increased US wage inequality.
