Questions and Answers

What is the effect of a price ceiling set below the equilibrium price?

  • It causes the price to increase above the controlled level.
  • It leads to excess supply of the commodity.
  • It creates equilibrium in the market.
  • It results in excess quantity demanded for the commodity. (correct)

Which of the following accurately describes the law of supply in a price ceiling scenario?

  • A price ceiling results in a decrease in quantity demanded.
  • A price ceiling leads to an increase in quantity supplied.
  • A price ceiling below equilibrium drives prices higher.
  • A price ceiling may lead to a decrease in quantity supplied if prices drop. (correct)

What is the primary goal of implementing a price ceiling?

  • To ensure supply remains equal to demand at all times.

Study Notes

Price Controls and Market Efficiency

  • Price ceilings: Governments set maximum prices. Producers can charge any price below the ceiling. If the ceiling is below the equilibrium price, quantity demanded exceeds quantity supplied (shortage).

  • Price floors: Governments set minimum prices. Prices cannot fall below the floor. If the floor is above the equilibrium price, quantity supplied exceeds quantity demanded (surplus).

  • Excise taxes: Governments levy taxes on specific goods. Revenue generated, and the burden of the tax (who pays more) are determined by the price elasticities of supply and demand.

Welfare Analysis

  • Consumer surplus: Measures consumer well-being. It's the difference between the willingness to pay and the price paid. Graphically, it's the area under the demand curve and above the price.

  • Producer surplus: Measures producer well-being. It's the difference between the price received and the willingness to produce. Graphically, it's the area above the supply curve and below the price.

  • Total surplus: Sum of consumer and producer surplus. The market equilibrium maximizes total surplus when the allocation is efficient.

Deadweight Loss

  • Deadweight loss (DWL): Loss in total surplus from a market distortion. Occurs when the quantity traded is not at the market equilibrium. Price ceilings and price floors, among other government interventions, result in DWL. Calculated as the area of a triangle on a graph.

Missing Markets

  • Missing markets: Exist when mutually beneficial trades don't occur. This can result from public policy, lack of technology, or lack of information. Examples: shortages of housing.

Market Efficiency and Equilibrium

  • Market equilibrium: Occurs when quantity demanded equals quantity supplied. At this point total surplus is maximized.
  • Market Inefficiency: occur when markets are not functioning optimally, resulting in deadweight loss.

Firm Behavior and Cost Curves

  • Profit maximization: Firms try to maximize profits. Profits = total revenue – total costs.

  • Costs of production: Include explicit costs (actual payments) and implicit costs (opportunity costs).

  • Cost curves: Important cost curves include total cost (TC), average total cost (ATC), and marginal cost (MC). ATC curves are saucer-shaped, and MC curves intersect ATC at its lowest point.

  • Relationship between cost curves: When MC is above ATC, ATC rises. And when MC falls below ATC, ATC falls.

Production Function and Marginal Product of Labor

  • Production function: Describes the relationship between inputs (e.g., labor) and output. A key aspect of this function is the marginal product of labor.

  • Marginal product of labor: Represents the increase in output from an additional worker, holding other inputs constant (short run). The law of diminishing marginal product states that MP of Labor usually decreases as more workers are added.

  • Costs of production: Are functions of output (not input, labor) and thus, total cost = total variable cost + total fixed cost and these increased in the same direction (up) of the production level.

  • Important Relationships: The relationship between Marginal Cost, Average Total Cost and Average Variable Cost. MC intersects ATC at ATC's lowest point; AVC follows the same pattern relative to its own MC, intersecting at the point where AVC is also lowest.

Utility Maximization

  • Utility: Measures the satisfaction derived from consuming goods and services.

  • Utility maximization: Consumers seek to maximize their utility subject to their budget constraint.

  • Marginal utility: The additional utility from consuming one more unit of a good. The "law of diminishing marginal utility" states that the additional satisfaction you receive from each additional unit is less then the previous unit consumed.

  • Budget constraint: Shows affordable consumption bundles. The slope of the budget line represents the relative price of the two goods.

Elasticity

  • Price elasticity of demand: Measures how responsive quantity demanded is to a change in price. Knowing that for any good elasticity of demand/supply are important to determine the relative burden of a tax on producers/consumers.

Government Intervention: Taxes and Subsidies

  • Tax incidence: The way in which the burden of a tax is shared between consumers and producers.

  • Tax revenue: Calculated by multiplying the tax rate by the quantity traded after the imposition of the tax.
