Monetary Policy & External Balance

← Back to Domain-Specific Families

Abstractions about inflation, exchange rates, credit channels, monetary rules, quantitative easing, trade measures, demand, and balance-of-payments adjustment.

15 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.

• Agflation — A period when food and agricultural-commodity prices rise substantially faster than the general price level, creating a sector-specific inflation gap with acute food-security and distributional consequences.
• Balance of payments — A double-entry statistical account recording a country's transactions with the rest of the world over a period across current, capital and financial accounts.
• Consumer price index — A periodically updated weighted index estimating price change for a defined basket of household consumption goods and services relative to a reference period or chain.
• Credit channel — Explain how monetary-policy impulses are amplified when financial frictions change borrowers' external-finance premiums or banks' supply of intermediated credit, altering spending beyond the conventional interest-rate channel.
• Currency crisis — A financial crisis in which confidence in a currency or exchange-rate regime collapses, producing abrupt depreciation, reserve loss, forced devaluation or abandonment of a peg.
• Effective exchange rate index — An index of a currency’s value against a weighted basket of trading-partner or competitor currencies relative to a base period.
• Gold points — The upper and lower exchange-rate bounds under the gold standard at which the cost of settling by shipping gold became cheaper than buying or selling foreign bills.
• Horizontalism — A post-Keynesian theory of endogenous money in which bank lending creates deposits and central banks accommodate the resulting reserve demand at a policy-controlled interest rate.
• Import ratio — A sovereign-liquidity indicator comparing a country's imports with its foreign-exchange reserves, commonly expressed as imports divided by reserves or as months of import cover.
• Monetary conditions index — A weighted combination of an interest rate and an exchange rate intended to summarize their joint influence on aggregate demand relative to a baseline.
• Paradox of toil — A zero-lower-bound macroeconomic result in which a collective increase in willingness to work lowers wages and expected inflation enough to raise real interest rates, reduce demand and decrease equilibrium employment.
• Principle of effective demand — In Keynesian macroeconomic theory, determine output and employment where entrepreneurs' aggregate proceeds expectations meet the aggregate supply price, allowing the resulting demand-constrained position to occur below full employment.
• Quantitative easing — A central-bank balance-sheet policy that purchases longer-duration or riskier financial assets at announced scale when ordinary short-rate policy is constrained, seeking to ease broader financial conditions through yields, portfolios, liquidity and expectations.
• Taylor rule — A monetary-policy reaction rule that sets a nominal short-term interest-rate target as a neutral rate plus responses to inflation's deviation from target and the output gap.
• Trade-weighted effective exchange rate index — An index combining a currency’s bilateral exchange rates using trading-partner weights to summarize its multilateral external value.
