Capitalism is an economic system and an ideology based on private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system and competitive markets. In a capitalist market economy, decision-making and investment are determined by the owners of the means of production in financial and capital markets, whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.
Economists, political economists, sociologists, and historians have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include laissez-faire or free market capitalism, welfare capitalism and state capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition and state-sanctioned social policies. The degree of competition in markets, the role of intervention and regulation and the scope of state ownership vary across different models of capitalism. The extent to which different markets are free, as well as the rules defining private property, are matters of politics and policy. Most existing capitalist economies are mixed economies, which combine elements of free markets with state intervention and in some cases economic planning.
