Tax Incidence Examples: Sales Tax and Excise Taxes Explained

📚 Quick Study Guide

🔍 Tax incidence refers to the division of a tax burden between buyers and sellers.
• ⚖️ It depends on the relative elasticities of demand and supply.
• 📈 When demand is more elastic than supply, sellers bear a larger portion of the tax burden.
• 📉 When supply is more elastic than demand, buyers bear a larger portion of the tax burden.
• 💰 Sales tax is a percentage of the selling price collected by the seller.
• ⛽ Excise tax is a per-unit tax on a specific good or service.
• 📝 The formula for tax incidence on buyers: $\frac{Elasticity\, of\, Supply}{Elasticity\, of\, Supply + |Elasticity\, of\, Demand|}$
• 📝 The formula for tax incidence on sellers: $\frac{|Elasticity\, of\, Demand|}{Elasticity\, of\, Supply + |Elasticity\, of\, Demand|}$
