Classical political economy 发表评论(0) 编辑词条

The classical school economic thought emerged in Britain in the late 18th century. The classical political economists Adam Smith, David Ricardo, Jean-Baptiste Say, and John Stuart Mill published analyses of the production, distribution and exchange of goods in a market that have since formed the basis of study for most contemporary economists.

In France, 'Physiocrats' like François Quesnay promoted free trade based on a conception that wealth originated from land. Quesnay's Tableau Économique (1759), described the economy analytically and laid the foundation of the Physiocrats' economic theory, followed by Anne Robert Jacques Turgot who opposed tariffs and customs duties and advocated free trade. Richard Cantillon defined long-run equilibrium as the balance of flows of income, and argued that the supply and demand mechanism around land influenced short-term prices.

Adam Smith's attack on mercantilism and his reasoning for "the system of natural liberty" in The Wealth of Nations (1776) are usually taken as the beginning of classical political economy. Smith devised a set of concepts that remain strongly associated with capitalism today, particularly his theory of the "invisible hand" of the market, through which the pursuit of individual self-interest unintentionally produces a collective good for society. It was necessary for Smith to be so forceful in his argument in favor of free markets because he had to overcome the popular mercantilist sentiment of the time period.He criticized monopolies, tariffs, duties, and other state enforced restrictions of his time and believed that the market is the most fair and efficient arbitrator of resources. This view was shared by David Ricardo, second most important of the classical political economists and one of the most influential economists of modern times. In The Principles of Political Economy and Taxation (1817), he developed the law of comparative advantage, which explains why it is profitable for two parties to trade, even if one of the trading partners is more efficient in every type of economic production. This principle supports the economic case for free trade. Ricardo was a supporter of Say's Law and held the view that full employment is the normal equilibrium for a competitive economy. He also argued that inflation is closely related to changes in quantity of money and credit and was a proponent of the law of diminishing returns, which states that each additional unit of input yields less and less additional output.

The values of classical political economy are strongly associated with the classical liberal doctrine of minimal government intervention in the economy, though it does not necessarily oppose the state's provision of a few basic public goods.Classical liberal thought has generally assumed a clear division between the economy and other realms of social activity, such as the state.

While economic liberalism favors markets unfettered by the government, it maintains that the state has a legitimate role in providing public goods. For instance, Adam Smith argued that the state has a role in providing roads, canals, schools and bridges that cannot be efficiently implemented by private entities. However, he preferred that these goods should be paid proportionally to their consumption (e.g. putting a toll). In addition, he advocated retaliatory tariffs to bring about free trade, and copyrights and patents to encourage innovation.
