It gauges the restrictiveness of a country’s FDI rules by looking at the four main types of restrictions on FDI: 1) foreign equity limitations, 2) discriminatory screening or approval mechanisms, 3) restrictions on the employment of foreigners as key personnel, and 4) other operational restrictions, e.g. on branching and on capital repatriation or on land ownership by foreign-owned enterprises. The administrative burden discourages firm registration.
