  • Multiplier Effect

    A chain reaction where initial investment spending leads to repeated rounds of increased consumption and total economic output.
  • Investment Spending

    Expenditure by firms on capital goods, triggering higher household incomes and further economic activity.
  • Household Income

    Money earned by individuals or families, which rises when firms invest and hire more workers.
  • Consumption

    Spending by households on goods and services, which increases as incomes rise from investment.
  • Marginal Propensity to Consume

    Fraction of additional income that households spend rather than save, influencing the size of the multiplier.
  • Marginal Propensity to Save

    Portion of extra income that households set aside, equal to one minus the marginal propensity to consume.
  • GDP

    Total value of goods and services produced, which grows by more than the initial investment due to the multiplier.
  • Multiplier Formula

    Equation 1 divided by 1 minus the marginal propensity to consume, used to calculate total output increase.
  • Chain Reaction

    Series of repeated spending rounds where each increase in income leads to further consumption.
  • Aggregate Demand

    Overall demand for goods and services in the economy, boosted by the multiplier effect from investment.
  • Infinite Series

    Mathematical concept representing repeated rounds of spending, summed up by the multiplier formula.
  • Initial Expenditure

    The first round of investment spending that sets off the multiplier process in the economy.
  • Fiscal Policy

    Government actions affecting investment and consumption, influencing the multiplier and aggregate demand.
  • Economic Growth

    Expansion of total output, accelerated by higher investment and a larger multiplier.
  • Denominator

    The value 1 minus marginal propensity to consume in the multiplier formula, determining the size of the effect.
