Open trade and investment policies can be a powerful force for raising living standards. Economists have long emphasised this point and it is confirmed by much research. For example, the OECD¡¯s Growth Study estimated that a 10 percentage point increase in trade openness translates over time into an increase of around 4% in per capita income in the OECD area. The recent dynamism of China and India demonstrates how trade and investment liberalisation can make a major contribution to raising incomes and reducing poverty in developing countries.
