Economist

An economist is a professional and practitioner in the social science discipline of economics.

The individual may also study, develop, and apply theories and concepts from economics and write about economic policy. Within this field there are many sub-fields, ranging from the broad philosophical theories to the focused study of minutiae within specific markets, macroeconomic analysis, microeconomic analysis or financial statement analysis, involving analytical methods and tools such as econometrics, statistics, economics computational models, financial economics, regulatory impact analysis and mathematical economics.

History of the profession

Although economists are now recognized as specialists in a distinct profession, the earliest contributors to economic thought were polymath philosophers. Some of the earliest economic writings date to antiquity, notably Aristotle’s Oeconomica and Xenophon’s Oeconomicus. These works addressed, in rudimentary form, themes such as the division of labour.

In the seventeenth century, as early modern economic thought began to take shape, its leading writers were typically broad-ranging scholars who wrote on economics alongside philosophy and law. This was true of Richard Cantillon, who described what later came to be known as the Cantillon effect, and of David Hume, who anticipated the quantity theory of money. In 1690, Nicholas Barbon, the inventor of mortgages, wrote A Discourse of Trade, one of the first works promoting free trade, and analyzing the nature of capital markets.

Adam Smith, in An Inquiry into the Nature and Causes of the Wealth of Nations, wrote one of the first major works devoted entirely to economics, helping to establish economics as a distinct field within the social sciences.
