Capitalism is an economic system based on the private ownership of the means of production and their operation for profit.    Central characteristics of capitalism include  capital accumulation, competitive markets, price system, private property, property rights recognition, voluntary exchange, and wage labor.  In a  market economy, decision-making and investments are determined by owners of wealth, property, or ability to maneuver capital or production ability in capital and financial markets—whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets. 
Economists, historians, political economists and sociologists have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include or laissez-faire free-market capitalism, anarcho-capitalism, state capitalism and welfare 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 and the role of intervention and regulation as well as the scope of state ownership vary across different models of capitalism.  The extent to which different markets are free and the rules defining private property are matters of politics and policy. Most of the existing capitalist economies are  mixed economies that combine elements of free markets with state intervention and in some cases economic planning. 
Market economies have existed under many
forms of government and in many different times, places and cultures. Modern capitalist societies developed in Western Europe in a process that led to the Industrial Revolution. Capitalist systems with varying degrees of direct government intervention have since become dominant in the Western world and continue to spread. Economic growth is a characteristic tendency of capitalist economies.
