This paper provides a revised measure of regulatory restrictions on inward foreign direct investment (FDI) for OECD countries and extends the approach to 13 non-member countries.

When combined with other factors having an influence on foreign investment decisions, it has proven to be a good predictor of countries\u27 inward FDI performance
