Economic freedom or economic liberty is the ability of members of a society to undertake economic actions. 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 classical liberal and libertarian traditions emphasizing free markets, free trade, and private property under free enterprise. Another approach to economic freedom extends the welfare economics study of individual choice, with greater economic freedom coming from a "larger" (in some technical sense) set of possible choices. Other conceptions of economic freedom include freedom from want and the freedom to engage in collective bargaining.
