Economist in 1817: Ricardo's comparative advantage

The scholar of scarcity — from Adam Smith's pin factory to the central-bank decision room, still asked to predict what no model fully captures. "Economist" descends from the Greek oikonomia — household management — and for most of history that is all it meant: the person who ran an estate. Adam Smith called himself a moral philosopher; Britain's first professor of political economy, Thomas Malthus, was not appointed until 1805, at the East India Company College. The salaried specialist who measures, models and forecasts whole economies is barely a hundred and fifty years old, younger than the railway.

There is no license to practice and no protected title — anyone may be called an economist — yet the working hierarchy is among the most credential-bound of any profession. Research posts at central banks, the IMF or a university effectively require a PhD that takes five to six years after a mathematics-heavy degree, and a single annual hiring ritual, the job market, decides where most new doctorates in the field begin.

This page follows the trade from Xenophon's estate manual and Ibn Khaldun's Muqaddimah through Smith, Ricardo, Marx and Keynes to the econometricians and randomistas of the present. It covers how people actually enter the field today, what the daily work looks like inside a central bank or a faculty, who reached the top of the profession and how, and how much of the job AI can realistically absorb.
