Macroeconomic Policy & Fiscal Dynamics

← Back to Domain-Specific Families

Abstractions about government fiscal and monetary policy effects on the macroeconomy, covering fiscal-stance concepts (Austerity, Public Debt, Operating Surplus, Tax Buoyancy), monetary-policy anomalies (Monetarist Paradox, Price Puzzle, Wallace Neutrality), and shock or downturn phenomena like Growth Recession and Sudden Stop.

11 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Austerity — A deliberate public fiscal program intended to reduce a deficit or debt path through spending restraint, tax increases, or both, assessed against a specified policy baseline and time horizon.
• Dividend discount model — An equity-valuation model that prices a share as the present value of expected future dividends discounted at the required return.
• Functional Finance — A macroeconomic policy doctrine that judges sovereign fiscal and monetary operations by their effects on employment, inflation, output, and interest conditions rather than by budget balance as an end in itself.
• Growth Recession — A period of positive but sub-threshold real economic growth in which output expands too slowly to stabilize employment, so unemployment or labor-market slack rises without an ordinary output recession.
• Monetarist Paradox — A monetary-policy time-horizon reversal: easier money may depress nominal rates initially but raise them later through inflation and expectations, while sustained restraint can produce lower long-run nominal rates.
• Operating Surplus — The national-accounts balance of production income left after labor compensation and production taxes less subsidies, before property income.
• Price Puzzle — A monetary-policy VAR anomaly in which an identified contractionary shock is followed by an estimated price rise.
• Public Debt — The dated stock of debt-instrument liabilities owed by a defined government sector, measured under explicit perimeter, consolidation, valuation, currency, maturity, and gross-or-net conventions.
• Sudden Stop (Economics) — An abrupt, unusually large decline in external capital inflows that forces rapid balance-of-payments and domestic-spending adjustment, often with credit contraction, depreciation, and output loss.
• Tax buoyancy — The observed proportional response of tax revenue to growth in GDP or another stated income base, including discretionary policy and administrative effects that tax elasticity removes.
• Wallace Neutrality — A conditional irrelevance theorem under which public-liability swaps leave equilibrium prices and real allocations unchanged when fiscal backing is fixed and the assets have no distinguishing services or trading constraints.
