“The field of economics is not exempt from the consequences of chaos and complexity. Marketplaces are indeterminate; value is subjective; and outcomes are subject to interpretation. Economic forecasting is just as nebulous, being based on the probability of statistical information that may or may not be accurate.”

Ragnar Frisch (1926) "On a Problem in Pure Eco­nomics: Translated by JS Chipman." Preferences, Utility, and Demand: A Minnesota Symposium. 1926."
Original in French:
Intermediaire entre les mathematiques, la statistique et l'economie politique, nous trouvons une discipline nouvelle que ion peut, faute de mieux, designer sous le nom de reconometrie. L'econometrie se pose le but de soumettre les lois abstraites de l'economie politique theorique ou l'economie 'pure' A une verification experimentale et numeriques, et ainsi de constituer, autant que cela est possible, l'economie pure en une science dans le sens restreint de ce mot.
1920

Context: By this time, the era of cut-and-run economics ought to be finished. Such an economy cannot be rationally defended or even apologized for. The proofs of its immense folly, heartlessness, and destructiveness are everywhere. Its failure as a way of dealing with the natural world and human society can no longer be sanely denied. That this economic system persists and grows larger and stronger in spite of its evident failure has nothing to do with rationality or, for that matter, with evidence. It persists because, embodied now in multinational corporations, it has discovered a terrifying truth: If you can control a people’s economy, you don’t need to worry about its politics; its politics have become irrelevant. If you control people’s choices as to whether or not they will work, and where they will work, and what they will do, and how well they will do it, and what they will eat and wear, and the genetic makeup of their crops and animals, and what they will do for amusement, then why should you worry about freedom of speech? In a totalitarian economy, any "political liberties" that the people might retain would simply cease to matter. If, as is often the case already, nobody can be elected who is not wealthy, and if nobody can be wealthy without dependence on the corporate economy, then what is your vote worth? The citizen thus becomes an economic subject.

After all control and institutions and processes are immediate things. They can all be translated into terms of human conduct...
