Theory-Based Models

Use theory-based models as mechanism maps. They are strongest when the reader needs a clean channel, an equation, and a disciplined first pass before adding data or heterogeneity.

Reading lens

Frame

Goods market

Output, spending, saving, and demand conditions.

IS-LM Model

Demand and liquidity conditions at one short-run equilibrium.

AD-AS-LRAS Model

Demand, supply, capacity, output, and price-level adjustment.

Keynesian Cross

Planned expenditure, income, multipliers, and demand shifts.

Permanent Income Hypothesis

Permanent income, temporary shocks, and consumption smoothing.

Life-Cycle Hypothesis

Work-life income, retirement, wealth, and consumption smoothing.

Growth

Capital, technology, population, and long-run output.

Solow Growth Model

Saving, depreciation, population growth, technology, and steady-state capital.

Harrod-Domar Growth Model

Saving, capital-output ratios, depreciation, and warranted growth.

AK Endogenous Growth Model

Investment, broad capital, depreciation, and sustained growth.

Ramsey-Cass-Koopmans Model

Optimal saving, consumption paths, capital dynamics, and transition speed.

Business cycle

Shock propagation, gaps, persistence, and adjustment.

RBC Simplified

Productivity shocks, capital accumulation, labor choice, and consumption smoothing.

Money market

Money demand, liquidity, reserves, and nominal anchors.

Quantity Theory of Money

Money, velocity, output, and the price level in one accounting identity.

Fisher Equation

Saving, investment demand, government borrowing, and the real interest rate.

Labor

Employment, wages, matching, unemployment, and slack.

Phillips Curve

Labor-market slack, inflation pressure, expectations, and supply shocks.

Okun's Law

Output gaps and unemployment gaps read against potential output.

Inflation

Prices, expectations, and nominal adjustment.

New Keynesian Phillips Curve

Expected inflation, output gaps, price stickiness, and cost-push shocks.

Dynamic AD-AS Model

Inflation expectations, demand, supply, and policy-driven adjustment.

Sticky-Price Model

Price adjustment limits and the real effects of nominal demand.

Policy

Rules, credibility, fiscal choices, and stabilization.

Taylor Rule

Policy-rate settings from inflation gaps, output gaps, and r-star.

Ricardian Equivalence

Government borrowing, taxes, saving responses, and fiscal timing.

Open economy

Exchange rates, capital flows, trade, and external balance.

Mundell-Fleming Model

Open-economy demand with exchange rates, capital mobility, and policy choice.

Heckscher-Ohlin Trade Model

Factor endowments, comparative advantage, trade patterns, and income effects.
