The failure of socialism in countries around the world can be traced to one critical defect: it is a system that ignores incentives.
In a capitalist economy, incentives are of the utmost importance. Market prices, the profit-and-loss system of accounting, and private property rights provide an efficient, interrelated system of incentives to guide and direct economic behavior. Capitalism is based on the theory that incentives matter!
The strength of capitalism can be attributed to an incentive structure based upon the three Ps: (1) prices determined by market forces, (2) a profit-and-loss system of accounting and (3) private property rights. The failure of socialism can be traced to its neglect of these three incentive-enhancing components.FEE.org
The price system in a market economy guides economic activity so flawlessly that most people don’t appreciate its importance. Market prices transmit information about relative scarcity and then efficiently coordinate economic activity. The economic content of prices provides incentives that promote economic efficiency.
Profits and Losses
Socialism also collapsed because of its failure to operate under a competitive, profit-and-loss system of accounting. A profit system is an effective monitoring mechanism which continually evaluates the economic performance of every business enterprise. The firms that are the most efficient and most successful at serving the public interest are rewarded with profits. Firms that operate inefficiently and fail to serve the public interest are penalized with losses.
Private Property Rights
A third fatal defect of socialism is its blatant disregard for the role of private property rights in creating incentives that foster economic growth and development. The failure of socialism around the world is a “tragedy of commons” on a global scale.
