# Economics > [!info] Gateway page > Orientation and the schools map here; the discipline spine — big questions, schools of thought, measurement, and the politics — is at [[Economics Hub]]. Economics is the study of how societies allocate scarce resources, but the reason it occupies real estate in a knowledge base about political power is narrower and sharper than that: **economic argument is the primary vehicle through which contested political preferences get laundered into technical necessity.** A distributional choice framed as a moral question invites disagreement. The same choice framed as what the models require does not. Understanding the discipline well enough to see which is happening is the point of this section. The field's internal disagreements are real and are not resolvable by better data alone, because the schools differ on prior questions — what counts as an explanation, what humans are assumed to be, and what the counterfactual is. Five clusters matter here. **Classical and neoclassical** economics supplies the baseline: markets clear, prices carry information, and rational agents optimize. [[Classical Economics]] and [[Neoclassical Economics]] together form the framework everything else is a departure from. Its enduring contribution is genuine — the price mechanism really is an extraordinary information-processing device — and its enduring weakness is that its assumptions about information, rationality, and market power are heroic in exactly the cases policy is usually about. **[[Keynesian Economics]]** broke the baseline by arguing that aggregate demand can settle at a persistent underemployment equilibrium and that government spending is therefore not merely redistributive but stabilizing. It dominated postwar policy until the 1970s stagflation, which it handled badly, and the discipline has been re-litigating that defeat ever since. **The conservative counter-revolution** is the branch this vault tracks most closely, because it is the branch that became infrastructure. [[Monetarism]] under Friedman restored the primacy of the money supply. The [[Chicago School]] extended price-theoretic reasoning into law, regulation, and antitrust, and in doing so reshaped what courts consider a cognizable harm. The [[Austrian School]] supplied the epistemological case against planning, and — through [[Public Choice Theory]] — the argument that regulators are self-interested actors rather than neutral referees, which is both a serious insight and an all-purpose solvent for regulatory legitimacy. [[Supply-Side Economics]] supplied the political payload: the claim that rate cuts pay for themselves, which has survived four decades of unsupportive evidence because its function was never primarily empirical. **The institutional and heterodox critique** — [[Marxian Economics]], institutional economics, [[Heterodox Economics]], [[MMT]] — asks the questions the mainstream brackets: who holds power in the exchange, how do institutions shape what counts as a market, and what actually constrains a currency-issuing government. **[[Behavioral Economics]]** attacked the rationality assumption from inside the mainstream and won more ground than any other challenger, precisely because it kept the method and revised only the agent. The measurement layer deserves separate attention because it is where political manipulation is easiest and least visible. Which indicator gets cited, how it is constructed, and whose experience it captures are all contestable choices — headline unemployment versus labor-force participation, CPI versus lived cost of essentials, GDP growth versus median wage. See [[Economic Indicators Hub]] for the constructed-ness of each. ## Where to go from here | Destination | What's there | |---|---| | [[Economics Hub]] | Full spine: big questions, all schools, measurement, economics and political power | | [[Economics Lexicon]] | The defined-terms layer | | [[Economic Indicators Hub]] | What each indicator measures, how it's built, and how it gets spun | | [[Austrian School]] · [[Chicago School]] · [[Public Choice Theory]] · [[Supply-Side Economics]] | The conservative counter-revolution | | [[Keynesian Economics]] · [[Monetarism]] · [[Neoclassical Economics]] · [[Classical Economics]] | The mainstream lineage | | [[Marxian Economics]] · [[Heterodox Economics]] · [[MMT]] | The critique | | [[Behavioral Economics]] | The rationality challenge — bridges to [[Decision Science]] | | [[Financial System Hub]] | The institutional companion: who actually moves the money | ## See also [[Neoliberalism]] · [[Regulatory Capture]] · [[Free Market Fundamentalism]] · [[Koch Network]] · [[How Federal Money Moves]] · [[Corporate Power]]
