Economic freedom, or economic liberty, is the agency of people to make economic decisions. This is a term used in economic and policy debates as well as in the philosophy of economics. One approach to economic freedom comes from the liberal tradition emphasizing free markets, free trade, and private property. Another approach to economic freedom extends the welfare economics study of individual choice, with greater economic freedom coming from a larger set of possible choices. Other conceptions of economic freedom include freedom from want and the freedom to engage in collective bargaining.
