  • Multiplier Effect
    A chain reaction where an initial change in spending or income leads to repeated increases in GDP throughout the economy.
  • Tax Multiplier
    A measure showing how a change in taxes impacts GDP, typically smaller and negative due to the inverse link between taxes and consumption.
  • Government Spending Multiplier
    A value indicating the total increase in GDP from an initial boost in government purchases, usually larger than the tax multiplier.
  • Disposable Income
    The portion of earnings available to households after taxes, used for both consumption and savings.
  • Consumption
    Household spending on goods and services, influenced by changes in disposable income and taxes.
  • Savings
    The part of disposable income not spent, which reduces the magnitude of the multiplier effect.
  • Aggregate Demand
    The total demand for goods and services in an economy, affected by changes in taxes and government spending.
  • Automatic Stabilizer
    A mechanism where taxes adjust with the business cycle, moderating economic fluctuations without new policy actions.
  • Business Cycle
    Recurring periods of economic expansion and recession, influencing tax collection and consumption levels.
  • Fiscal Policy
    Government actions involving taxes and spending to manage aggregate demand and economic stability.
  • Expansion
    A phase of the business cycle marked by rising GDP, income, and tax collection, often reducing household consumption.
  • Recession
    A period of declining GDP and income, leading to lower taxes and increased household consumption.
  • Equilibrium GDP
    The level of output where aggregate demand equals aggregate supply, altered by changes in taxes or government spending.
  • Discretionary Policy
    Deliberate government interventions to change spending or taxes, distinct from automatic stabilizers.
  • Chain Reaction
    A process where increased spending or income triggers further rounds of consumption and economic activity.
