Interactive index

Simulators

Interactive macroeconomics, organized by mechanism

Choose the mechanism first: accounting identity, monetary plumbing, cycle pressure, policy rule, or open-economy constraint. The index points to the page where the assumptions are explained before the interactive controls.

Mechanism map

Choose a mechanism to inspect

The hub is an index. Interactive controls stay on the concept or policy page where the assumptions are stated.

National accounts

Production, income, expenditure, and cycle timing.

Money and banking

Aggregates, settlement, central-bank plumbing, reserves, and liquidity stress.

Cycles, prices, and labor

Labor tightness, demand pressure, supply pressure, and inflation diagnosis.

Policy rules and balance sheets

Rate rules, debt dynamics, fiscal stabilizers, and macroprudential stress.

Open economy and growth

Exchange-rate regimes, external balance sheets, and growth accounting.

National accounts

Index
01

GDP, GNP, and NNI calculator

Y=C+I+G+NXY = C + I + G + NXReconciles expenditure, income, production, and national-income bridges.Use when students need the accounting identity before arguing about growth or living standards.02

Business-cycle phase reader

Steps through expansion, peak, contraction, trough, and recovery signals.Use when recession dating, leading indicators, and labor-market lags are being compared.

Money and banking

Index
03

Bank and Fed balance-sheet accounting

Shows bank assets, deposits, reserves, Fed liabilities, TGA, ON RRP, and equity.Use before money-creation debates so the balance-sheet signs are settled.04

Money aggregate builder

M2=M1+S+TDs+MMFrM_2 = M_1 + S + TD_s + MMF_rBuilds M0, M1, M2, and broader layers from currency, deposits, and near-money claims.Use when the definition of money itself is the source of confusion.05

Loan creates deposit and settlement

Separates loan origination from interbank reserve settlement and funding gaps.Use when correcting the idea that banks mechanically lend out pre-existing reserves.06

Fed floor-system simulator

Compares scarce-reserve and abundant-reserve regimes using IORB, ON RRP, reserves, and the discount rate.Use for post-2008 operating-framework lessons and rate-control mechanics.07

QE and QT transmission map

Tracks Fed assets, reserves, deposits, TGA and ON RRP offsets, and term-premium pressure.Use when balance-sheet size and policy-rate stance need to be separated.08

Multiplier versus modern banking

m=1+cc+rm = \frac{1 + c}{c + r}Compares textbook reserve multipliers with capital, profitability, credit demand, and funding limits.Use when students need to separate the textbook identity frame from the modern lending engine.09

Money, velocity, output, and prices

MV=PYMV = PYDecomposes nominal spending into money growth, velocity, real output, and inflation.Use when quantity-theory language needs a growth-rate interpretation.10

Monetary base versus broad money

Separates currency, reserves, deposits, excess reserves, and the broad/base ratio.Use when central-bank balance-sheet growth and household deposit money are being conflated.11

Deposit flight and bank stress

Runs deposit outflows through reserves, facilities, securities sales, losses, and ending capital.Use for liquidity-versus-solvency lessons after bank-run episodes.12

Reserve-requirement policy simulator

Tests when reserve requirements bind versus when capital or credit demand binds first.Use when a class treats reserve ratios as if they always control lending.13

Global money-definition compare

Compares M2, M3, M4, broad-money depth, credit growth, inflation, and real money growth across economies.Use when cross-country money statistics are being compared without checking definitions.

Cycles, prices, and labor

Index
14

Labor tightness and inflation simulator

Links demand, participation, matching efficiency, vacancies, unemployment, wages, and core inflation pressure.Use for Beveridge-curve shifts, Phillips-curve pressure, and slack diagnostics.15

Demand shock versus supply shock

Separates demand, import costs, energy costs, capacity, expectations, output gaps, and inflation.Use when the same inflation rate could call for different policy readings.

Policy rules and balance sheets

Index
16

Taylor rule and yield-curve simulator

it=rt∗+πt+α(πt−π∗)+βxti_t = r_t^* + \pi_t + \alpha(\pi_t - \pi^*) + \beta x_tConnects inflation, slack, r-star, policy inertia, term premium, breakevens, and the curve slope.Use when a policy-rate argument needs a rule benchmark and a market-rate bridge.17

Fiscal stabilizers and debt dynamics

Runs slack, taxes, transfers, stimulus, rates, growth, debt, and rollover through next-period debt ratios.Use when fiscal support and debt arithmetic must be judged in the same frame.18

Housing credit and macroprudential stress

Moves rates, house prices, incomes, LTVs, default stress, expected bank losses, and capital buffers.Use for borrower-based rules, credit cycles, and household balance-sheet stress.

Open economy and growth

Index
19

Open-economy trilemma simulator

Tests how exchange-rate regime, capital mobility, and shocks allocate pressure across reserves, output, and autonomy.Use when currency regimes, capital controls, and monetary independence are being traded off.20

Solow and growth-accounting simulator

Separates saving, depreciation, population growth, capital deepening, TFP, and steady-state movement.Use when students need to distinguish transitional growth from sustained living-standard growth.21

External balance-sheet simulator

Turns current-account flows, NIIP, FX valuation, foreign-currency exposure, and nominal GDP into a stock-flow read.Use when a current-account story needs to be reconciled with valuation and debt stocks.

Formal model lane

Model graphs live in the model workbench

This hub keeps calculators and teaching simulators separate from the model graph workbench. Use Models when the question is a formal DSGE, empirical, theoretical, or agent-based graph.
