Macroeconomics

Absolute Advantage The ability of one nation to produce more output per unit of input than another, and why it alone does not determine beneficial trade patterns.

Accelerator Principle The mechanism by which a small increase in consumer demand triggers a much larger surge in business investment, amplifying economic expansions and contractions.

Aggregate Hours Worked Total labor input in an economy measured by cumulative hours worked across employed persons.

AK Growth Model An endogenous growth model where capital-driven technological progress sustains permanent growth without assuming exogenous innovation.

Asset Price Inflation Rapid appreciation of financial and real assets, distinct from consumer-price inflation, with substantial macroeconomic consequences.

Automatic Stabilizers: How They Cushion a Recession Without New Legislation Learn how automatic stabilizers—unemployment insurance, progressive taxes, and transfer programs—cushion recessions by boosting spending and reducing tax drag without need for new laws.

Average Hourly Earnings The mean wage per worker hour including overtime compensation, tracked monthly by the Bureau of Labor Statistics.

Balance of Payments The comprehensive accounting system recording all economic and financial transactions between a country and the rest of the world.

Balance of Payments Crisis: Causes and Warning Signs How countries fall into balance of payments crises: reserve depletion, current account deficits, sudden stops of foreign capital, and the conditions that trigger IMF intervention.

Balance Sheet Recession An economic downturn in which private-sector firms and households prioritise debt repayment over investment and spending, overwhelming fiscal stimulus.

Balanced Growth Path The steady-state trajectory where output, capital, and labour all grow at the same constant rate, with constant ratios between them.

Base Effects Statistical distortions in year-over-year inflation rates caused by unusually high or low prices from the prior-year period.

Beveridge Curve The inverse relationship between job vacancy rates and unemployment rates, mapping the efficiency of labour market matching.

Birth-Death Model in Nonfarm Payrolls Birth-death model nonfarm payrolls explains the BLS statistical adjustment for unobserved business creation and closure that can distort near-term employment readings.

Bounce-Back Recovery: Mechanics and Limits A bounce-back recovery is a sharp, rapid rebound from a brief economic contraction, driven by pent-up demand and a quick return to normal capacity utilization.

Breakeven Inflation Rate The market-implied inflation rate derived from the yield spread between nominal and inflation-protected Treasury securities.

Business Cycle The business cycle is the pattern of expansions and contractions in economic activity. It comprises four phases: expansion, peak, contraction (recession), and trough.

Business Cycle Risk for Retirees: Sequence-of-Returns in Downturns Business cycle risk for retirees centers on sequence-of-returns: early-retirement losses during downturns can permanently reduce lifetime wealth, regardless of long-term average returns.

Capacity Utilization Rate The percentage of a nation's installed industrial production capacity that is actually in active use at a given time.

Capacity Utilization Rate as a Macroeconomic Indicator How the Federal Reserve's capacity utilization rate measures industrial production, inflation pressure, and business cycle stage for investors.

Capex Cycle: How Business Investment Drives the Business Cycle Learn how waves of capital expenditure amplify economic expansions and deepen recessions through the accelerator mechanism.

Capital Account (BOP) The narrow balance-of-payments sub-account recording transfers of wealth and sales of non-produced assets between countries.

Capital Deepening The process of increasing capital stock per worker, raising labour productivity until diminishing returns create a growth ceiling.

Capital Flows Movement of investment money across national borders in pursuit of returns or risk diversification.

Capital-Output Ratio The amount of capital stock required to produce one unit of GDP; a key parameter in growth models and a measure of economic efficiency.

Capital-Output Ratio in Growth Theory The capital-output ratio relates the total stock of physical capital to annual output. It reveals how much investment an economy needs to sustain growth and differs sharply across countries.

Catch-Up Growth in Developing Economies Catch-up growth in developing economies allows capital-scarce nations to grow faster than rich countries by adopting proven technologies, when institutions and policy create the right conditions.

Chain-Weighted GDP The Fisher chain index method the U.S. uses to calculate real GDP, updating price weights annually to avoid base-year bias.

Chained CPI A cost-of-living index that updates the consumption basket weights annually, capturing real-time consumer substitution.

Chained vs Fixed-Weight Price Indexes: Substitution Bias Chained price indexes update weights annually to reflect consumer behavior, reducing substitution bias. Fixed-weight indexes lock in baskets and overstate inflation.

Club Convergence in Economic Growth Club convergence explains why economically similar countries converge toward each other while diverging from dissimilar ones, creating persistent growth clubs.

Coincident Indicator Economic metrics that move in lockstep with the business cycle, confirming its current phase and measuring cycle strength.

Commodity Price Inflation: How It Transmits to Consumer Prices How commodity prices flow through supply chains to consumer inflation. Charts the path from raw materials to retail and where transmission stalls.

Comparative Advantage Why nations gain from specialising in goods where their opportunity costs are relatively lowest, even when one nation is more productive overall.

Composite PMI The combined manufacturing and services Purchasing Managers' Index used as a real-time GDP growth proxy and early recession signal.

Conditional Convergence Why poorer countries grow faster only when compared to nations with similar structural characteristics, not across all countries universally.

Conference Board LEI: Components and How to Interpret It The Conference Board Leading Economic Index tracks ten economic indicators to forecast recessions and expansions. Learn what each component measures and how to read the signals.

Construction Output as a Leading Economic Indicator Construction output and building permits lead the business cycle, signaling economic expansion or contraction before GDP growth appears.

Construction Spending Value of new building and renovation activity, key macroeconomic indicator of demand and investment.

Consumer Confidence and the Business Cycle Consumer confidence reflects household spending power and wealth. Learn how confidence surveys predict recession turning points and amplify cycles.

Consumer Price Index The Consumer Price Index (CPI) measures inflation in consumer prices. It tracks the monthly change in prices paid by households for goods and services.

Continuing Jobless Claims Continuing jobless claims count the number of people who are actively receiving unemployment insurance benefits in a given week. It measures persistent joblessness.

Contraction Phase Period of declining economic activity, falling incomes, and rising unemployment within the business cycle.

Convergence Hypothesis Whether poor nations catch up to rich ones over time as they accumulate capital and adopt better technology, or whether inequality persists.

Core Inflation Core inflation measures price growth excluding volatile food and energy prices. It isolates the underlying inflation trend driven by demand and supply factors.

Core Inflation vs Headline Inflation: What the Fed Watches and Why Core inflation excludes volatile food and energy; headline includes everything. Learn why the Fed watches both metrics and what each reveals about price pressure.

Core PCE Inflation Personal consumption expenditure inflation excluding food and energy, a key measure of underlying inflation trends.

Cost-Push Inflation Inflation driven by supply-side cost shocks rather than excess aggregate demand.

CPI vs PCE: Which Inflation Measure Is More Accurate? Comparison of the two main US inflation gauges—coverage, weighting, substitution bias, and why the Federal Reserve prefers PCE while headlines cite CPI.

Creative Destruction Schumpeter's framework: innovation destroys obsolete firms and industries, creating dynamic economic progress.

Credit Crunch: Definition and Causes What a credit crunch is, how tightening lending standards amplify economic downturns, and why it differs from a normal rise in interest rates.

Credit Cycle The self-reinforcing boom-bust pattern in which rising asset values and confidence lower lending standards, fuelling debt accumulation and eventual collapse.

Credit Spread Widening and Recession Risk Credit spread widening—a rise in the yield gap between risky and safe bonds—often signals recession risk as investors demand higher compensation for default risk and growth slows.

Crowding Out Effect: How Government Borrowing Affects Private Investment Crowding out effect government spending: when large fiscal deficits raise interest rates, private firms and households borrow less, reducing investment and growth.

Current Account Adjustment Mechanism How exchange rates, income, and relative prices work to correct persistent current account deficits automatically.

Current Account Balance The broadest measure of a country's economic transactions with the world, tracking trade, investment income, and transfers.

Current Account Components: Goods, Services, Income, and Transfers The current account balances merchandise trade, services, primary income, and secondary income; together they measure a nation's net external position.

Current Account Deficit A deficit on current account measures a nation's negative balance of trade and investment income with the rest of the world.

Current Account Surplus Positive net inflow from trade in goods and services plus primary and secondary income sources.

Cyclical Unemployment Cyclical unemployment is joblessness caused by weak aggregate demand during recessions and downturns. It rises when the economy weakens and falls as the economy recovers.
