  • Laffer Curve
    A parabolic graph showing how tax revenue first rises then falls as tax rates increase, illustrating the non-linear relationship between tax size and government revenue.
  • Tax Revenue
    The total funds collected by the government from taxes, calculated as the tax amount per unit multiplied by the quantity exchanged.
  • Quantity Exchanged
    The number of units bought and sold in a market, which decreases as taxes increase due to higher costs for buyers and lower returns for sellers.
  • Demand Curve
    A downward-sloping line representing the relationship between price and quantity demanded by consumers in a market.
  • Supply Curve
    An upward-sloping line showing the relationship between price and quantity supplied by producers in a market.
  • Equilibrium
    The market point where the quantity demanded equals the quantity supplied, before any tax is imposed.
  • Per Unit Tax
    A fixed amount charged on each unit sold, affecting both the price buyers pay and the price sellers receive.
  • Downward Slope
    The portion of the Laffer Curve where increasing tax rates lead to lower tax revenue due to reduced market activity.
  • Parabolic Graph
    A curve shaped like an arch, used to depict the Laffer Curve’s rise and fall of tax revenue with changing tax rates.
  • Arthur Laffer
    The economist who conceptualized the relationship between tax rates and tax revenue, giving his name to the Laffer Curve.
  • Optimal Tax Policy
    A strategy aiming to set tax rates at a level that maximizes government revenue without excessively discouraging economic transactions.
  • Tax Size
    The magnitude of the tax imposed per unit, influencing both the price structure and the quantity exchanged in the market.
  • Price Paid by Buyers
    The final amount consumers pay after a tax is added, which rises as tax rates increase.
  • Price Received by Sellers
    The net amount producers get after the tax is deducted from the sale price, which falls as tax rates increase.
  • Maximizing Tax Revenue
    The point on the Laffer Curve where the combination of tax rate and quantity exchanged yields the highest possible government income.
