The paper develops a dynamic model of the North-South product cycle, in whi
ch Northern firms continuously transfer production to two Southern countrie
s through foreign direct investment (FDI), The technologies of Northern mul
tinationals are eventually imitated by Southern firms. The competition amon
g Southern countries for FDI through R&D, trade, FDI and intellectual prope
rty rights policies are examined, A Southern countrys subsidy to attract in
ward FDI benefits its production workers at the expense of those in other S
outhern countries. However, a Southern country's import tariffs against the
North benefit the production workers of all Southern countries. (C) 2001 E
