In the history of economic thought, ancient economic thought refers to the ideas from people before the Middle Ages.

Economics in the classical age is defined in the modern analysis as a factor of ethics and politics, only becoming an object of study as a separate discipline during the 18th century.[1][2][3][4]

Ancient Near East

Code of Ur-Nammu, 2100–2050 BC.
The upper part of the stele of Hammurabi's code of laws.

Economic organization in the earliest civilizations of the Fertile Crescent was driven by the need to efficiently grow crops in river basins. The Euphrates and Nile valleys were homes to earliest examples of codified measurements written in base 60 and Egyptian fractions.

Egyptian keepers of royal granaries, and absentee Egyptian landowners are reported in the Heqanakht papyri. Historians of this period note that the major tool of accounting for agrarian societies, the scales used to measure grain inventory, reflected dual religious and ethical symbolic meanings.[5]

The Erlenmeyer tablets give a picture of Sumerian production in the Euphrates Valley around 2200–2100 BC, and show an understanding of the relationship between grain and labor inputs (valued in "female labor days") and outputs and an emphasis on efficiency. Egyptians measured work output in man-days. The development of sophisticated economic administration continued in the Euphrates and Nile valleys during the Babylonian Empire and Egyptian Empires when trading units spread through the Near East within monetary systems. Egyptian fraction and base 60 monetary units were extended in use and diversity to Greek, early Islamic culture, and medieval cultures. By 1202, Fibonacci's use of zero and Vedic-Islamic numerals, motivated Europeans to apply zero as an exponent, birthing modern decimals 350 years later.

The city-states of Sumer developed a trade and market economy based originally on the commodity money of the Shekel which was a certain weight measure of barley, while the Babylonians and their city-state neighbors later developed the earliest system of economics using a metric of various commodities, that was fixed in a legal code.[6] The early law codes from Sumer could be considered the first (written) economic formula, and had many attributes still in use in the current price system today: codified amounts of money for business deals (interest rates), fines in money for 'wrongdoing', inheritance rules, laws concerning how private property is to be taxed or divided, etc.[7] For a summary of the laws, see Babylonian law.

Earlier collections of (written) laws, just prior to Hammurabi, that could also be considered rules and regulations as to economic law for their cities include the codex of Ur-Nammu, king of Ur (c. 2050 BC), the laws of Eshnunna (c. 1930 BC)[8] and the code of Lipit-Ishtar of Isin (c. 1870 BC).

Ancient Greco-Roman world


Some scholars assert economic thought similar to the modern understanding occurred during the 18th century or the Enlightenment, as early economic thought was based on metaphysical principles which are incommensurate with contemporary dominant economic theories such as neo-classical economics.[1][9]

Several ancient Greek and Roman thinkers made various economic observations, especially Aristotle and Xenophon. Many other Greek writings show understanding of sophisticated economic concepts. For instance, a form of Gresham's law is presented in AristophanesFrogs, and beyond Plato's application of sophisticated mathematical advances influenced by the Pythagoreans is his appreciation of fiat money in his Laws (742a–b) and in the pseudo-Platonic dialogue, Eryxias.[10] Bryson of Heraclea was a neo-platonic who is cited as having heavily influenced early Muslim economic scholarship.[11]

Hesiod

In the opinion of the Austrian school of economics the first economist is thought to be Hesiod, by the fact of his having written on the fundamental subject of the scarcity of resources, in Works and Days.[13][14][15] His contribution to economic thought is at least in his relevancy to the practice of economical activity in the depositing and lending of grain, as his writings are "... the chief resource for details as to Grecian agriculture ..." and that according to Loudon (1825) he provided " ... directions for the whole business of family economy in the country".[16]
