Internationally, Heritage publishes the annual "Index of Economic Freedom", which measures a country's freedom in terms of property rights and freedom from government regulation. The factors used to calculate the "Index" score are corruption in government, barriers to international trade, income tax and corporate tax rates, government expenditures, rule of law and the ability to enforce contracts, regulatory burdens, banking restrictions, labor regulations, and black market activities. A British-born academic, Charles W. L. Hill, after discussing the international shift toward a market-based economic system and Heritage Foundation's "Index of Economic Freedom", said "given that the Heritage Foundation has a political agenda, its work should be viewed with caution."
