Econ 213problem Set 2name P: Evaluation of Market Interventions and Externalities

Econ 213 Problem Set 2 asks students to analyze various economic scenarios, including labor market equilibrium, price controls, externalities, and consumer and producer surpluses. The assignment requires applying theoretical concepts such as supply and demand graphs, price ceilings, externality internalization, and surplus calculations to real-world-like situations involving wages, market shortages, pollution costs, and market surplus analysis.

Paper For Above instruction

Economic markets are characterized by the forces of supply and demand, which determine quantities exchanged at equilibrium prices. This problem set explores how government interventions, external costs, and market behaviors influence equilibrium outcomes, utilizing models and quantitative assessments to understand these effects.

1. Wages in the Internet Security Labor Market

The provided data showcases wages offered for Internet security professionals, along with quantities demanded and supplied at different wage levels:

• Wages: $50,000, $60,000, $70,000, $80,000, $90,000
• Quantities Demanded: 60,000, 50,000, 40,000, 30,000, 20,000
• Quantities Supplied: 20,000, 30,000, 40,000, 50,000, 60,000

a. Equilibrium Wage: The equilibrium occurs where quantity demanded equals quantity supplied. Combining the data, this happens at a wage of $70,000, where both demand and supply are at 40,000 workers. Hence, the equilibrium wage is $70,000.

b. Impact of a Price (Wage) Cap at $75,000: Imposing a wage cap at $75,000, which is above the equilibrium wage, theoretically would have no immediate effect since the market is already at equilibrium at $70,000. However, if the cap were set below $70,000, it would create a binding constraint.

c. Effect on Hiring: At a wage of $75,000, since this exceeds the equilibrium wage, no shortage or surplus is expected—more workers would be willing to work at that wage than employers would seek to hire. Therefore, the number of people hired remains at the equilibrium level—40,000—assuming the cap is non-binding. If a lower cap were imposed, such as at $65,000, it would create a shortage, reducing the number of hires below equilibrium, as demand declines and supply increases.

2. Effect of Price Ceilings on the Graham Crackers Market

In this scenario, policymakers consider capping the price of graham crackers to make them more affordable for consumers. A supply and demand graph illustrates the market equilibrium where the market price P* intersects with the demand D and supply S curves.

a. Graph Description: The vertical axis represents the price of graham crackers, and the horizontal axis displays quantity. The downward-sloping demand curve and upward-sloping supply curve intersect at equilibrium point E, where the market-clearing price is P. Imposing a price ceiling below P—say at a price Pc—creates a horizontal line below equilibrium, preventing the market from reaching its natural price.

b. Market Outcomes: Setting a price ceiling below the equilibrium price leads to excess demand—more consumers want graham crackers at Pc than producers are willing to supply—forming a shortage. Consumers benefit from lower prices, but producers are less willing to supply, resulting in a decrease in quantity supplied and a lasting shortage. Over time, shortages may cause rationing or black markets, distorting the market efficiency.

3. Externalities and Renewable Pricing of Electricity

Pollution from coal-fired power plants represents a negative externality, where environmental harm is not reflected in the market price of electricity. Economists argue that internalizing external costs would lead to higher prices and reduced consumption, aligning private costs with social costs.

a. Graph Illustration: A supply and demand graph depicts the market. The initial supply curve (S) reflects private costs, with the equilibrium price (Pe) and quantity (Qe). Including external costs shifts the supply curve vertically upward to a new curve (S’), representing social costs. The intersection of S’ with demand (D) determines the socially optimal price (Ps) and quantity (Qs), which are higher and lower, respectively. The difference between Pe and Ps indicates the internalized externality cost.

b. Challenges in Pricing Externalities: Determining the accurate external cost involves complex valuation, scientific uncertainty, and measuring long-term impacts such as climate change. Political resistance, measurement difficulties, and valuation disagreements complicate incorporating external costs into electricity prices effectively.

4. Consumer and Producer Surplus Calculations

Given individual willingness to pay for ginger ale, the total consumer surplus at a market price of $5 can be calculated by summing the differences between each buyer’s maximum willingness to pay and the market price, including only those whose willingness exceeds $5.

Consumer Willingness to Pay:

• Scott: $10
• Dennis: $4
• Greg: $8
• Dave: $7
• Mike: $5

Buyers willing to pay more than $5 are Scott, Greg, and Dave:

• Scott: $10 - $5 = $5
• Greg: $8 - $5 = $3
• Dave: $7 - $5 = $2

Total consumer surplus = $5 + $3 + $2 = $10.

Producer Willingness to Supply:

• Gene: $6
• Brandon: $3
• Matt: $2
• Cooper: $11
• Jed: $5

Producers willing to supply at a price of $5 are Gene, Cooper, and Jed:

• Gene: $6 - $5 = $1
• Cooper: $11 - $5 = $6
• Jed: $5 - $5 = $0

Total producer surplus = $1 + $6 + $0 = $7.

Impact of Price Fall to $2: At a lower price, only Greg and Dave will purchase, increasing consumer surplus, but producer surplus decreases as fewer producers cover their costs or some may exit the market, leading to potential shortages and reduced supply.

These calculations demonstrate the importance of market prices in balancing consumer and producer welfare, and how external interventions and market shifts alter surpluses and overall market efficiency.
