National Accounts & Monetary Systems

← Back to Domain-Specific Families

Abstractions about how money, saving, and international balances are measured and governed at the national level, including national accounting identities (flow of funds, saving identity, gross national product), international monetary relationships (exchange rate, purchasing power parity, net foreign assets), and banking or policy mechanisms (fractional-reserve banking, tight money policy, Triffin dilemma).

21 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.

• Absolute income hypothesis — A Keynesian consumption hypothesis in which current real consumption rises with current real disposable income but by less than the income increase, so the marginal propensity to consume is positive and below one and average propensity tends to fall as income rises.
• Denomination Effect — The denomination effect is a change in spending behavior when equal cash value is packaged as one large unit rather than several smaller units.
• Domestic Liability Dollarization — The denomination of domestic banking-system deposits and loans in a foreign hard currency, creating balance-sheet dependence on a unit of account not controlled by the home monetary authority.
• Economic Overheating — A macroeconomic state in which aggregate demand or activity presses against sustainable economy-wide productive capacity over a stated horizon.
• Exchange rate — The quoted price at which one currency can be exchanged for another, expressed as units of a quote currency per unit of a base currency under a specified market, time, and transaction convention.
• Financial Repression — A policy configuration that channels domestic savings toward favored borrowers through paired return restraints and captive financing rules.
• Fiscal Gap — A conditional measure of the sustained revenue or spending adjustment needed to meet a declared long-run government fiscal target under a specified projection.
• Flow of funds — Flow of funds accounts are a system of interrelated balance sheets for a nation, calculated periodically.
• Forced saving — An involuntary gap between household income and current consumption caused by goods shortages, unaffordable prices, or credit constraints rather than by a voluntary plan to defer consumption.
• Fractional-Reserve Banking — A banking system in which deposit-taking banks hold only part of their deposit liabilities in liquid reserves while investing or lending the remainder under monetary and prudential constraints.
• Gross national product — The former production-framed name for gross national income: the gross primary income attributable to a country's residents, equal to GDP plus residents' factor income from abroad minus factor income paid to nonresidents.
• Gross Value Added — Measure a producer's output minus intermediate consumption, then aggregate contributions under national-account valuation rules.
• Invisible balance — The balance of international receipts and payments for services and other non-goods transactions—such as transport, tourism, consulting, and licensing—contrasted with the visible balance in merchandise trade.
• Net Foreign Assets — The net foreign asset (NFA) position of a country is the value of its net claims on the rest of the world (RoW), i. e. the value of the assets that country owns abroad, minus the value of the domestic assets owned by foreigners.
• Purchasing power parity — Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies.
• Saving identity — The saving identity equates aggregate saving sources with physical investment in national-income accounting.
• Social reserves — Social Reserves refer to the intangible ties that bind a country together.
• Tax Deduction — Tax Deduction is a recurring tax law, public finance identity in which an allowed amount is subtracted from taxable income rather than directly from tax liability.
• Tight money policy — A third monetary policy strategy, targeting the money supply, was widely followed during the 1980s, but has diminished in popularity since then, though it is still the official strategy in a number of emerging economies.
• Triffin Dilemma — The structural bind in which a national currency serving as the world's reserve asset must run persistent deficits to supply global liquidity, yet those same deficits erode the confidence that makes the currency worth holding — two roles one issuer cannot jointly satisfy over time.
• Visible balance — The visible trade balance (merchandise trade balance) is that part of the balance of trade figures that refers to international trade in physical goods, but not trade in services; it thus contrasts with the invisible balance.
