Study Notes

Welfare Economics

  • Studies the impact of resource allocation on economic well-being.
  • Focuses on how much of each good is produced, who produces it, and who consumes it.

Willingness to Pay (WTP)

  • The maximum amount a buyer is willing to pay for a good.
  • Represents the value a buyer places on a good or service.

Consumer Surplus

  • The difference between the price a buyer is willing to pay for a good and the price they actually pay.
  • Measures the benefit buyers gain from participating in a market.

Demand Curve and Consumer Surplus

  • The demand curve reflects buyers' willingness to pay and can be used to measure consumer surplus.
  • The area below the demand curve and above the price represents consumer surplus.

Producer Surplus

  • The difference between the price a seller receives for a good and the cost of producing that good.
  • Measures the benefit sellers gain from participating in a market.

Cost

  • The value of resources a seller gives up to produce a good.
  • Includes the cost of all resources, encompassing the value of the seller's time.

Supply Curve and Producer Surplus

  • The supply curve reflects sellers' willingness to sell.
  • The area above the supply curve and below the price represents producer surplus.

Market Efficiency

  • Maximizes total surplus, which is the sum of consumer surplus and producer surplus.
  • Occurs when goods are consumed by those who value them most and produced by those with the lowest production costs.
