Examples of Government Taxes & Subsidies Shifting Supply

📚 Quick Study Guide

• 🏭 Supply Curve: Represents the quantity of a good or service that producers are willing to sell at different prices.
• 💰 Taxes: Taxes increase the cost of production, leading to a decrease in supply (leftward shift of the supply curve).
• 🍎 Specific Tax: A fixed amount of tax per unit of output. This causes a parallel shift in the supply curve.
• ⚖️ Ad Valorem Tax: A percentage tax on the value of the good or service. This causes a non-parallel shift in the supply curve.
• 💸 Subsidies: Subsidies decrease the cost of production, leading to an increase in supply (rightward shift of the supply curve).
• 🌱 Impact of Taxes & Subsidies: These interventions affect market equilibrium, leading to changes in price and quantity.
• 📈 Formulas to Remember:
  • ➕ Supply Curve Shift (Tax): $New\ Supply\ Curve = Original\ Supply\ Curve + Tax\ Amount$
  • ➖ Supply Curve Shift (Subsidy): $New\ Supply\ Curve = Original\ Supply\ Curve - Subsidy\ Amount$
