  • Multiplier
    A factor showing how an initial change in spending leads to a larger change in GDP, calculated as one over one minus marginal propensity to consume.
  • Marginal Propensity to Consume
    The proportion of additional income that is spent on consumption, influencing the size of the multiplier in the economy.
  • Autonomous Consumption
    Spending on goods and services that occurs even when income is zero, reflecting basic needs like food and shelter.
  • Aggregate Expenditures
    The total amount spent in an economy, represented as the sum of consumption and investment in a private closed model.
  • Private Closed Economy
    An economic model excluding government and international trade, focusing only on households and businesses.
  • Consumption Function
    An equation expressing total consumption as the sum of autonomous consumption and marginal propensity to consume times income.
  • Investment
    Spending by businesses on capital goods, which contributes to aggregate expenditures and influences GDP through the multiplier.
  • Equilibrium GDP
    The level of output where aggregate expenditures equal total income, ensuring no unintended inventory changes.
  • Disposable Income
    Income available to households after taxes, used for consumption and saving in simplified models without government.
  • Algebraic Derivation
    The process of rearranging and factoring equations to isolate variables and reveal relationships, such as the multiplier formula.
  • GDP
    The total value of goods and services produced in an economy, used as a measure of economic output and equilibrium.
  • Equilibrium
    A state where aggregate expenditures match total output, resulting in stable economic conditions without excess supply or demand.
  • Multiplier Effect
    The phenomenon where an increase in spending causes a greater overall increase in economic output due to repeated rounds of consumption.
  • Aggregate Demand
    The total demand for goods and services in an economy, influenced by changes in consumption, investment, and the multiplier.
