History of Economic Thought
City states of Sumer developed a trade and market economy based originally on the commodity money of Shekel which was a certain weight measure of barley, while the Babylonians and their city state neighbors later developed earliest system of economics using a metric of various commodities, which was fixed in a legal code. The early law codes from Sumer could be considered as first economic formula, and it had many attributes still in use in the current price system today. Such as codified amounts of money for business deals , fines in money for 'wrong doing', inheritance rules, laws concerning how private property is to be taxed or divided, etc.
The modern economic theory is customarily said to have begun with Adam Smith . A wide number of economic thinkers, going all the way back to the ancient Greek philosophers influenced Adam smith. The works of Aristotle had a profound influence on Thomas Aquinas and, through Aquinas, on subsequent scholastic thinking.
Economic thought dates from earlier Mesopotamian, Greek, Roman, Indian, Chinese, Persian and Arab civilizations. Notable writers include Aristotle, Chanakya (also known as Kautilya), Qin Shi Huang, Thomas Aquinas and Ibn Khaldun through to the 14th century. Bryson of Heraclea was a neo-platonic who is cited as having heavily influenced early Muslim economic scholarship. Joseph Schumpeter initially considered the late scholastics of the 14th to 17th centuries as "coming nearer than any other group to being the 'founders' of scientific economics" as to monetary, interest, and value theory within a natural-law perspective. After discovering Ibn Khaldun's Muqaddimah, however, Schumpeter later viewed Ibn Khaldun as being the closest forerunner of modern economics, as many of his economic theories were not known in Europe until relatively modern times but Ibn Khaldun's ideas were not absorbed by his society, nor were they carried forward by its future generations.
Nonetheless, recent research indicates that the Indian scholar-philosopher Chanakya (c. 340-293 BCE) predates Ibn Khaldun by a millennium and a half as the forerunner of modern economics, and has written more expansively on this subject, particularly on political economy. His magnum opus, the Arthashastra (The Science of Wealth and Welfare), is the genesis of economic concepts that include the opportunity cost, the demand-supply framework, diminishing returns, marginal analysis, public goods, the distinction between the short run and the long run, asymmetric information and the producer surplus. In his capacity as an advisor to the throne of the Maurya Empire of ancient India, he has also advised on the sources and prerequisites of economic growth, obstacles to it and on tax incentives to encourage economic growth. However, it does not seem likely that modern economics has any important indebtedness to Chanakya.

Later, two other groups called 'mercantilists' and 'physiocrats', more directly influenced the subsequent development of the subject. Both groups were associated with the rise of economic nationalism and modern capitalism in Europe. Mercantilism was an economic doctrine that flourished from the 16th to 18th century in a prolific pamphlet literature, whether of merchants or statesmen. It held that a nation's wealth depended on its accumulation of gold and silver. Nations without access to mines could obtain gold and silver from trade only by selling goods abroad and restricting imports other than of gold and silver. The doctrine called for importing cheap raw materials to be used in manufacturing goods, which could be exported, and for state regulation to impose protective tariffs on foreign manufactured goods and prohibit manufacturing in the colonies.
Physiocrats, a group of 18th century French thinkers and writers, developed the idea of the economy as a circular flow of income and output. Adam Smith described their system "with all its imperfections" as "perhaps the purest approximation to the truth that has yet been published" on the subject. Physiocrats believed that only agricultural production generated a clear surplus over cost, so that agriculture was the basis of all wealth.
Thus, they opposed the mercantilist policy of promoting manufacturing and trade at the expense of agriculture, including import tariffs. Physiocrats advocated replacing administratively costly tax collections with a single tax on income of land owners. Variations on such a land tax were taken up by subsequent economists (including Henry George a century later) as a relatively non-distortionary source of tax revenue. In reaction against copious mercantilist trade regulations, the physiocrats advocated a policy of laissez-faire, which called for minimal government intervention in the economy.
