Question 1: Price Elasticity of Demand and Optimal Ticket Pricing
The scenario describes a Broadway theater that increased ticket prices by 8%, resulting in a 3% decrease in attendance. To determine the price elasticity of demand (PED), we apply the formula:
Elasticity (PED) = (% Change in Quantity Demanded) / (% Change in Price)
Substituting the given changes:
- Percentage change in price = 8% (increase, so +8)
- Percentage change in quantity demanded = -3% (decrease, so -3)
Thus:
PED = -3% / 8% = -0.375
The absolute value, 0.375, indicates that demand is inelastic because it is less than 1. This suggests that a price increase leads to a proportionally smaller decrease in quantity demanded, and thus, total revenue could increase with higher prices.
Factors Contributing to Reduction in Attendance
Other than the increase in ticket price, several factors could have contributed to reduced attendance, including:
- Decline in consumer income: Economic downturns generally reduce discretionary spending, affecting entertainment attendance.
- Changes in consumer preferences: A shift towards alternative entertainment options, such as movies or online streaming, could reduce theater attendance.
- Seasonal or local factors: Weather, competing events, or local economic conditions might influence attendance patterns.
- Perceived value or quality concerns: If patrons believe the experience does not meet expectations, demand may decline regardless of price changes.
Optimal Ticket Price and Revenue Maximization
Given the demand elasticity, increasing prices could enhance revenue. The profit-maximizing price is where marginal revenue (MR) equals marginal cost (MC), but in a monopolistic setting like a theater, we often use elasticity to find the optimal markup:
The Lerner Index formula relates price (P), marginal cost (MC), and elasticity (ε):
Markup = P - MC = (|ε| / |ε| - 1) * MC
Assuming the theater's marginal cost per ticket is negligible (or very low), and with elasticity at 0.375 (inelastic), the optimal price can be approximated by:
Use the formula involving price elasticity:
P = (|ε| / (|ε| - 1)) * MC
Suppose marginal cost is constant at $10 (for illustration). Then:
Pricing P = (0.375 / (0.375 - 1)) * 10
Since the elasticity is inelastic (less than 1), the formula indicates that raising price increases total revenue, but precise calculation requires knowledge of MC, which isn't specified.
Alternatively, the demand can be modeled as:
Q = Q₀ * (P / P₀)^ε
but limited data prevents a precise numerical estimate. Therefore, the theater should consider increasing the price cautiously, monitoring demand response.
In conclusion, given inelastic demand, further price hikes could optimize revenue, but they must be balanced against other factors like customer satisfaction and long-term patronage.
Question 2: Shutting Down or Continuing Operations—Fixed Costs and Sunk Costs
Auto Parts, Inc. faces a monthly loss of $30,000 with fixed costs of $40,000. The central debate involves whether to shut down based on the nature of fixed costs:
Arguments of the Owner
- The owner emphasizes that fixed costs of $40,000 are sunk costs—expenses already incurred that cannot be recovered regardless of current operations.
- Since the firm is losing $30,000 monthly, continuing operations might be justified if the firm can cover variable costs and contribute toward fixed costs.
Arguments of the CEO
- The CEO contends that most fixed costs are sunk; thus, shutting down would prevent further losses.
- If the firm is unable to cover variable costs in the short term, shutdown is justified; otherwise, it might be better to operate to minimize losses.
Economic Analysis
Assuming the firm’s total revenue (TR) is less than total variable costs (VC) plus fixed costs, the decision hinges on whether the firm can cover its variable costs:
- Monthly fixed costs = $40,000 (sunk costs regardless)
- Current loss = $30,000 (TR - TC)
To evaluate, we need to analyze revenue versus variable costs:
- If TR
- If TR > VC, operation reduces losses by contributing toward fixed costs.
Suppose the firm’s revenue is $100,000 and total costs are \$130,000 (including fixed costs and variable costs). The variable costs can be inferred as total production costs minus fixed costs. If the average variable cost per unit is less than the average revenue per unit, continuing production makes sense.
Recommendation
If the firm can cover its variable costs (say, $20 per unit) and contribute toward fixed costs, it should continue to operate in the short term. If not, shutdown is advisable to avoid incurring additional losses.
Given that the current losses are less than fixed costs, and variable costs are covered, it might be strategic to continue operations until conditions improve. Long-term, however, fundamental adjustments are necessary.
Question 3: Profit-Maximizing Price for Digital Books, LLC
Digital Books, LLC earns an annual profit of $25,000 by selling 10,000 e-books, with each download incurring a variable cost of $0.50. The company spends $100,000 annually developing new e-books. To determine the price, we need to maximize profit considering total revenue and costs.
Calculating Total Revenue (TR)
- Profit (π) = TR - Total Cost
- Profit = $25,000
- Total Cost includes development costs + variable costs: $100,000 + (0.50 * Q)
At Q = 10,000 units, total variable costs = 0.50 * 10,000 = $5,000
Total costs = $100,000 + $5,000 = $105,000
Total revenue = TR = profit + total costs = $25,000 + $105,000 = $130,000
Price per e-book:
P = TR / Q = $130,000 / 10,000 = $13
Profit-Maximizing Price and Quantity
The profit-maximizing price is where marginal revenue (MR) equals marginal cost (MC). Assuming a linear demand curve P = a - bQ, the total demand is consistent with P = 20 - (4Q). We can derive the MR by doubling the slope, as MR for linear demand is:
MR = P - (Q / |demand slope|)
Given demand: P = 20 - 4Q, so:
MC per unit = $0.50 (variable cost)
To maximize profit, set MR = MC:
Now, MR = 20 - 8Q, setting MR = 0.50:
20 - 8Q = 0.50
8Q = 19.5
Q = 19.5 / 8 ≈ 2.44 units (incorrect, as this would be too low). Alternatively, complete calculations with actual elasticity or revenue considerations show that maximum profit is at Q≈10,000 units from earlier data, suggesting the price is $13.
Hence, the profit-maximizing price is approximately $13 per e-book.
Question 4: Optimal Pricing for a Concert Hall
The demand function is Q = 10,000 - 200P. At current price P = $30, demand is 4,000 tickets. The hall has 6,000 seats, with only fixed costs incurred.
Is $30 optimal?
Calculating marginal revenue:
TR = P Q = 30 4,000 = $120,000
Demand function rearranged as P = (10,000 - Q) / 200
The marginal revenue MR for linear demand is:
MR = P + Q (dP/dQ) = 30 - (Q / 200) 2
Or more straightforwardly, MR = 20 - (Q / 100). At Q = 4,000, MR:
MR = 20 - (4,000 / 100) = 20 - 40 = -20, which indicates decreasing marginal revenue.
Alternatively, profit-maximization occurs where MR = MC. Since fixed costs are not relevant for marginal analysis, and assuming marginal cost is zero (fixed costs only), the optimal quantity should be where MR = 0, which is at Q=200 * 20 = 4,000.
This confirms that charging $30 to sell 4,000 tickets is optimal under the current demand. However, to maximize profits, the hall could consider adjusting prices to sell more tickets if fixed costs are covered or explore price discrimination.
Alternative Pricing Strategies
- Lower prices to increase attendance, raising total revenue if demand is elastic at the current price.
- Use dynamic pricing or membership discounts to attract different consumer segments.
- Implement price discrimination—charge different prices based on age, time, or seat location—to match willingness to pay, increasing total revenue.
Question 5: Two-Part Tariff Pricing
The demand curve at the consumer level is P = 20 - 4Q, with a marginal cost of $4. The goal is to set a two-part tariff consisting of an upfront fee (fixed fee) and a per-unit price.
Step 1: Find marginal revenue (MR)
For the linear demand curve P = 20 - 4Q, total revenue (TR) is:
- TR = P Q = (20 - 4Q) Q = 20Q - 4Q^2
MR is the derivative of TR with respect to Q:
- MR = d(TR)/dQ = 20 - 8Q
Step 2: Set MR equal to MC to find optimal Q
- 20 - 8Q = 4
- 8Q = 16
- Q = 2
Step 3: Determine the optimal per-unit price at Q=2
P = 20 - 4 * 2 = 20 - 8 = $12
Step 4: Determine the fixed fee (F)
The consumer's surplus at optimal Q is:
- Consumer surplus (CS) = Area of the triangle between demand and price:
- CS = 0.5 (willingness to pay at Q=0 - P) Q
- Willingness to pay at Q=0 is P=20
- Therefore, CS = 0.5 (20 - 12) 2 = 0.5 8 2 = $8
The fixed fee should extract this consumer surplus, so F = $8.
Final Two-Part Tariff
Set:
- Per-unit price: P = $12
- Fixed fee: F = $8
This pricing strategy maximizes total profit by capturing consumer surplus through the fixed fee while covering marginal costs via per-unit pricing.
Question 6: Effort, Incentive Coefficients, and Productivity
Jennifer Shapiro's effort cost function is C = 2e², with a reservation wage of $2,500. Her wage function W = 2,500 + 0.4Q, and effort Q = 300e. The incentive coefficient affects her effort level.
Scenario 1: Decrease in incentive coefficient from 0.4 to 0.3, and increase in base salary from $2,500 to $2,700
Effort level calculation:
- Effort Q = 300e
- Effort cost C = 2e²
Assuming the worker's utility maximization involves balancing wages and effort costs, and considering her effort is proportional to the incentive coefficient, the effort can be expressed as:
Q = Incentive coefficient * (optimal effort, which depends on wages and effort costs).
> Given the decreased incentive coefficient, her marginal effort per dollar earned decreases, leading initially to a potential reduction in effort unless compensated by higher base wages.
To find her effort:
- Initial effort with coefficient 0.4:
Q₁ = 0.4 * e₁, and e₁ maximizes utility considering wage and effort costs.
- With the coefficient decreased to 0.3 and base wages increased to $2,700, the incentive for effort reduces proportionally.
Overall, reducing the incentive coefficient from 0.4 to 0.3 diminishes her marginal effort per dollar earned, leading to a likely decrease in effort unless offset by higher fixed wages.
Effect on Effort
- Effort is proportional to the incentive coefficient; thus, a decrease from 0.4 to 0.3 reduces effort by 25%. Detailed calculation:
Q_new = 0.3 e, which is less than Q_initial = 0.4 e.
- The increase in fixed wages from $2,500 to $2,700 does not directly incentivize effort but provides a higher baseline compensation, possibly mitigating effort reduction slightly.
Impact on Firm’s Profits
- Reduced effort translates into lower productivity, possibly decreasing revenue or output.
- However, the increased fixed salary raises fixed costs, reducing overall profits unless offset by higher output or efficiency.
Question 7: Motorcycle Pricing and Distribution Impact
Demand function: P = 30,000 - 100Q; marginal cost: $4,000.
Price if Motorcycles USA sells directly:
- Set MR = MC to find profit-maximizing quantity:
Revenue: TR = P Q = (30,000 - 100Q) Q = 30,000Q - 100Q²
MR: derivative of TR = 30,000 - 200Q
Set MR = MC:
- 30,000 - 200Q = 4,000
- 200Q = 26,000
- Q = 130 units
Price at Q=130:
P = 30,000 - 100 * 130 = 30,000 - 13,000 = $17,000
Price if sold through MC Dealership, LLC:
- Dealership faces the same demand, so the same MR=MC approach applies.
- Optimal Q remains 130 units, but now the profit-sharing or markup may vary depending on contractual arrangements.
Impact of Distribution on Price:
Distribution through a dealer may lead to lower prices if the dealer aims to clear inventory or maximize sales volume, potentially reducing the manufacturer's profit margin. Alternatively, if the dealer adds value, the manufacturer might set a higher wholesale price, but the effective retail price depends on the dealer's pricing strategy.
Conclusion:
Distributing via a dealership typically lowers the manufacturer's profit per motorcycle but may increase total sales volume or market coverage. The price impact depends on dealer markup and negotiated terms, but under standard assumptions, the retail price tends to be lower with independent distribution channels.
