Questions and Answers

What is the definition of consumer surplus?

  • The total value of the product purchased by consumers. opp
  • The sum total of all values consumers assign to a product.
  • The difference between the marginal value to the consumer and the price paid.
  • The increase in demand due to external factors. (correct)

What happens according to the First Law of Demand?

  • Consumers will purchase less as the price falls.
  • Consumers demand more when the price falls, if all other factors are constant. (correct)
  • Consumers will only buy when the price is less than the marginal value.
  • Consumer behavior is unaffected by changes in price.

What is the primary goal of marginal analysis by consumers?

  • To compare the prices of all products in the market.
  • To minimize the expenditure on goods purchased.
  • To maximize total consumption regardless of price.
  • To evaluate the additional value gained versus the price paid for each additional unit. (correct)

Study Notes

Pricing and Aggregate Demand

  • Total number of units consumers willing to purchase at a given price is known as Aggregate Demand or Market Demand.
  • Price is an extent decision; a trade-off between price and quantity driven by the relationship between Marginal Revenue (MR) and Marginal Cost (MC).
  • Reduce price (increase quantity) if MR > MC.
  • Increase price (reduce quantity) if MR < MC.
  • Optimum price occurs when MR = MC.
  • Price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price.

Elasticity and Price

  • MR > MC implies (P - MC)/P > 1/|e|.
  • If the current margin is larger than the desired margin, reduce price.
  • The higher the elasticity of demand (smaller 1/|e|), the less you can raise price over MC.
  • Five factors influence demand elasticity and optimal pricing:
    • Products with close substitutes have elastic demand.
    • Demand for an individual brand is more elastic than industry aggregate demand.
    • Products with many complements have less elastic demand.
    • Demand curves become more elastic in the long run.
    • As price increases, demand becomes more elastic.

Stay-Even Analysis

  • Stay-even analysis calculates the necessary sales volume to maintain the same profit level after price or cost changes.
  • By comparing the required sales volume to estimates or market surveys, businesses can determine the potential profitability of price adjustments.
