- A family-run bakery operates in a building owned by the family. To better track performance, the family decides to start paying rent to itself, transferring an amount equal to the property's market rental rate from the business account to a family trust account. How does this accounting change affect the bakery's profits?
Answer: Accounting profit decreases, but economic profit remains the same.
Before the change, the forgone rent was an implicit cost. After the change, it becomes an explicit cost. Accounting profit (TR - Explicit Costs) will decrease because explicit costs have increased by the amount of the rent. Economic profit (TR - Explicit Costs - Implicit Costs), however, will remain the same. The total economic cost has not changed; a cost of a specific amount has simply moved from the 'implicit' category to the 'explicit' category.
- A consultant can either work for a large firm for a salary of $120,000 or start her own practice. If she starts her own practice, she anticipates total revenues of $300,000 and explicit costs of $190,000. However, starting her own practice allows her to maintain a flexible schedule, which she values at $20,000 per year compared to the rigid schedule at the large firm. What is the economic profit of starting her own practice?
Answer: $10,000
First, calculate the accounting profit: $300,000 (Revenue) - $190,000 (Explicit Costs) = $110,000. Next, determine the net implicit cost. The implicit cost is the opportunity cost of the next best alternative. This includes the forgone salary of $120,000, but it is offset by the non-pecuniary benefit of the flexible schedule, valued at $20,000. So, the net implicit cost is $120,000 - $20,000 = $100,000. Economic profit is accounting profit minus net implicit costs: $110,000 - $100,000 = $10,000.
- A firm operating in a perfectly competitive market is in long-run equilibrium. Which of the following statements must be true for this firm?
Answer: The firm's accounting profit is equal to its implicit costs.
In long-run competitive equilibrium, firms earn zero economic profit. The formula for economic profit is: Economic Profit = Total Revenue - Explicit Costs - Implicit Costs. Setting economic profit to zero gives: 0 = (Total Revenue - Explicit Costs) - Implicit Costs. The term (Total Revenue - Explicit Costs) is the definition of accounting profit. Therefore, 0 = Accounting Profit - Implicit Costs, which means Accounting Profit = Implicit Costs. This level of accounting profit is also known as a normal profit.
- A consulting firm reports that for the past year, its total revenues were exactly equal to its total explicit costs. The founder, who also manages the firm, has a standing offer to work at a large corporation for a salary of $250,000 per year. Based on this information, the consulting firm is:
Answer: incurring an economic loss of $250,000.
The statement that total revenues equal total explicit costs means that the accounting profit is exactly zero (TR - Explicit Costs = 0). Economic profit also accounts for implicit costs. The founder's forgone salary of $250,000 is an implicit cost. Therefore, the economic profit is the accounting profit minus the implicit costs: $0 - $250,000 = -$250,000. The firm is incurring a significant economic loss.
- A farmer's accounting records show total revenue of $180,000 and total explicit costs of $120,000. The farmer owns land worth $400,000 that could be rented for $24,000 annually, and she forgoes a teaching salary of $55,000. If the farmer is just indifferent between continuing farming and pursuing alternatives, what must be her psychic income from farming?
Answer: $19,000
If the farmer is indifferent between farming and alternatives, her total utility from farming equals her total utility from alternatives. Accounting profit from farming = $180,000 - $120,000 = $60,000. Monetary opportunity costs = $24,000 (rent) + $55,000 (salary) = $79,000. For indifference: Net benefit from farming = Net benefit from alternatives. Net benefit from farming = $60,000 + psychic income. Net benefit from alternatives = $79,000. Therefore: $60,000 + psychic income = $79,000, so psychic income = $19,000. Choice B shows only accounting profit. Choice C shows total opportunity costs. Choice D shows only the rental opportunity cost.
- Two firms, Firm A and Firm B, are in the same perfectly competitive industry. Firm A consistently earns positive economic profit, while Firm B earns zero economic profit. Which statement is most consistent with this situation?
Answer: Firm A's accounting profit is greater than its implicit costs, while Firm B's is not.
Economic Profit = Accounting Profit - Implicit Costs. For Firm A, Economic Profit > 0, which implies Accounting Profit - Implicit Costs > 0, or Accounting Profit > Implicit Costs. For Firm B, Economic Profit = 0, which implies Accounting Profit - Implicit Costs = 0, or Accounting Profit = Implicit Costs. Firm B will not exit the market, as zero economic profit means it is covering all opportunity costs and is doing as well as its next best alternative.
- A firm earns an economic profit of $20,000. Its total revenue is $150,000, and its implicit costs are $30,000. What is the firm's accounting profit?
Answer: $50,000
When you encounter profit calculations, remember that economic profit and accounting profit measure profitability differently. Economic profit considers all costs (explicit and implicit), while accounting profit only considers explicit costs that involve actual cash payments.
To find accounting profit, you need to work backwards from the given information. Since economic profit equals total revenue minus total costs (both explicit and implicit), you can write: Economic Profit=Total Revenue−Explicit Costs−Implicit Costs
Substituting the known values: 20,000=150,000−Explicit Costs−30,000
Solving for explicit costs: Explicit Costs=150,000−30,000−20,000=100,000
Therefore, accounting profit = Total Revenue - Explicit Costs = 150,000−100,000=50,000
Looking at the wrong answers: Answer B (-$10,000) incorrectly suggests the firm has negative accounting profit, which would mean explicit costs exceed revenue. Answer C ($100,000) represents the explicit costs themselves, not the accounting profit. Answer D ($120,000) appears to subtract only implicit costs from total revenue, ignoring explicit costs entirely.
The correct answer is A) $50,000.
Remember this relationship: accounting profit is always greater than or equal to economic profit because accounting profit doesn't subtract implicit costs. When solving these problems, identify what type of costs are included in each profit measure, then work systematically through the calculations. - A company operates out of a building it owns, which it could rent out to another business for $5,000 per month. The company's monthly total revenue is $100,000, its monthly payroll is $60,000, and its monthly cost for materials is $30,000. Which of the following correctly identifies the company's monthly profits?
Answer: Accounting profit = $10,000; Economic profit = $5,000
Accounting profit is total revenue minus explicit costs. The explicit costs are payroll ($60,000) and materials ($30,000), totaling $90,000. So, accounting profit = $100,000 - $90,000 = $10,000. Economic profit subtracts implicit costs from accounting profit. The implicit cost is the opportunity cost of owning the building, which is the forgone rent of $5,000. So, economic profit = $10,000 - $5,000 = $5,000.
- A bakery owner calculates that her accounting profit is $80,000 annually. If she had invested her $200,000 startup capital in bonds yielding 4% annually instead of opening the bakery, and if she could have earned $45,000 working as a manager elsewhere, what is her economic profit?
Answer: $27,000
Economic profit = Accounting profit - Implicit costs. The implicit costs include the forgone interest on capital ($200,000 × 0.04 = $8,000) and the forgone salary ($45,000). Total implicit costs = $8,000 + $45,000 = $53,000. Therefore, economic profit = $80,000 - $53,000 = $27,000. Choice B incorrectly only subtracts the forgone salary. Choice C incorrectly only subtracts the forgone interest. Choice D confuses economic profit with accounting profit.
- An entrepreneur quits a job paying $100,000 per year to start a new business. In the first year, the business generates total revenue of $500,000 and incurs explicit costs of $410,000 for wages, materials, and rent. Which statement accurately describes the firm's performance in its first year?
Answer: The firm earns a positive accounting profit but incurs an economic loss.
Accounting profit is total revenue minus explicit costs: $500,000 - $410,000 = $90,000. Economic profit is accounting profit minus implicit costs. The primary implicit cost is the forgone salary of $100,000. Therefore, economic profit is $90,000 - $100,000 = -$10,000. The firm earns a positive accounting profit ($90,000) but an economic loss (-$10,000).
- A firm in a competitive market finds that at its current output level, its total revenue is $10,000, total explicit costs are $8,000, and total implicit costs are $3,000. The firm's total fixed costs are $4,000, all of which are explicit. What is the firm's situation and what should it do in the short run?
Answer: The firm has a positive accounting profit but an economic loss, and it should continue to operate.
First, assess the profits. Accounting profit = TR - Explicit Costs = $10,000 - $8,000 = $2,000 (positive). Economic profit = Accounting Profit - Implicit Costs = $2,000 - $3,000 = -$1,000 (an economic loss). Next, determine the short-run decision. The firm should operate if Total Revenue (TR) exceeds Total Variable Costs (TVC). Total explicit costs are $8,000 and total fixed costs (explicit) are $4,000, so TVC = $8,000 - $4,000 = $4,000. Since TR ($10,000) > TVC ($4,000), the firm is covering its variable costs and contributing to fixed costs, so it should continue to operate in the short run.
- The owner of a small firm currently pays $2,000 per month in rent for an office. The firm's monthly revenue is $20,000 and other explicit costs are $15,000. The owner is considering purchasing an office space, which would eliminate the rent payment but require using personal funds that currently generate $1,500 per month in interest. What would be the effect on the firm's monthly accounting and economic profits if the owner purchases the office?
Answer: Accounting profit will increase, and economic profit will also increase.
Currently: Accounting Profit = $20,000 - ($15,000 + $2,000) = $3,000. Economic Profit = $3,000 - implicit costs. After purchase: Explicit costs decrease by $2,000 (rent), so the new accounting profit = $20,000 - $15,000 = $5,000 (an increase of $2,000). However, a new implicit cost of $1,500 (forgone interest) is created. The change in economic profit is the change in accounting profit minus the change in implicit costs: +$2,000 - (+$1,500) = +$500. Both accounting profit and economic profit will increase.
- Over the course of a year, a perfectly competitive firm's economic profit changes from a positive value to zero. During this time, the market price for its product and its total explicit costs have both remained constant. Which of the following provides the best explanation for this change?
Answer: The opportunity cost of the resources supplied by the firm's owner has increased.
Economic Profit = Total Revenue - Explicit Costs - Implicit Costs. We are told TR (from constant price) and explicit costs are constant. This means that accounting profit (TR - Explicit Costs) has also remained constant. For economic profit to decrease from positive to zero while accounting profit remains constant, implicit costs must have increased. An increase in the opportunity cost of the owner's resources (e.g., a higher-paying job offer for the owner) would cause this.
- A firm in perfect competition has an accounting profit of $50,000. The owner invested $300,000 of personal savings (opportunity cost 5% annually) and works full-time managing the business instead of earning $60,000 at another job. The firm also received a one-time government subsidy of $20,000 this year. What is the firm's normal profit?
Answer: $75,000
Normal profit equals the total implicit costs that must be covered for the firm to remain in business long-term. This includes the opportunity cost of capital ($300,000 × 0.05 = $15,000) plus the opportunity cost of the owner's time ($60,000). Normal profit = $15,000 + $60,000 = $75,000. The government subsidy and accounting profit are irrelevant to determining normal profit, which is solely the implicit costs. Choice A incorrectly suggests normal profit is zero. Choice C only includes the salary opportunity cost. Choice D only includes the capital opportunity cost.
- If a firm's accounting profit is less than its normal profit for a sustained period, what must be true?
Answer: The firm is experiencing an economic loss and will likely exit the industry in the long run.
Normal profit is defined as the level of accounting profit that results in zero economic profit. This means normal profit is equal to the firm's total implicit costs. If accounting profit is less than normal profit, it means accounting profit is less than implicit costs. Since Economic Profit = Accounting Profit - Implicit Costs, this condition implies that the firm is experiencing an economic loss (a negative economic profit). A sustained economic loss provides an incentive for the firm to exit the industry in the long run.
- A consulting firm's annual financial data shows: total revenue $400,000, salaries and wages $200,000, rent $60,000, materials $40,000, and depreciation $20,000. The owner could earn $80,000 working elsewhere and has $500,000 invested in the business that could earn 6% in alternative investments. What is the firm's economic profit?
Answer: $-30,000
First, calculate total explicit costs: $200,000 + $60,000 + $40,000 + $20,000 = $320,000. Accounting profit = $400,000 - $320,000 = $80,000. Next, calculate implicit costs: foregone salary ($80,000) + foregone investment return ($500,000 × 0.06 = $30,000) = $110,000. Economic profit = Accounting profit - Implicit costs = $80,000 - $110,000 = -$30,000. The negative economic profit indicates the firm is not covering all opportunity costs. Choice A shows only accounting profit. Choice B incorrectly calculates implicit costs. Choice D adds instead of subtracts implicit costs.
- Two identical firms operate in the same perfectly competitive market. Firm A is owned by an entrepreneur who gave up a $90,000 salary, while Firm B is owned by a retiree with no employment alternatives. Both firms have identical revenues of $300,000 and explicit costs of $180,000. What can be concluded about their profit situations?
Answer: Both firms have identical accounting profits, but Firm B has higher economic profit
Accounting profit is the same for both firms: $300,000 - $180,000 = $120,000, since accounting profit only considers explicit costs. However, economic profit differs because implicit costs differ. Firm A's economic profit = $120,000 - $90,000 (foregone salary) = $30,000. Firm B's economic profit = $120,000 - $0 (no foregone salary) = $120,000. Therefore, both have identical accounting profits, but Firm B has higher economic profit. Choice A ignores the difference in implicit costs. Choice B incorrectly suggests accounting profit differs. Choice C correctly calculates Firm A's economic profit but matches the calculation shown in choice D.
- A technology startup has accounting profit of $200,000. The founder invested $1,000,000 of personal wealth (opportunity cost 7%) and works without salary, foregoing $120,000 annually. The company also holds patents worth $500,000 that could be licensed for $40,000 yearly. In a competitive market, what economic profit would signal the need for industry expansion?
Answer: Any positive economic profit would signal expansion
In perfectly competitive markets, any positive economic profit indicates that firms are earning above-normal returns, which signals profit opportunities that will attract new entrants and lead to industry expansion. The current firm's economic profit calculation: implicit costs = $70,000 (investment opportunity cost) + $120,000 (salary opportunity cost) + $40,000 (licensing opportunity cost) = $230,000. Current economic profit = $200,000 - $230,000 = -$30,000. While this firm has negative economic profit, the question asks about the general principle: any positive economic profit in a competitive market signals expansion opportunities. Zero economic profit (Choice C) represents long-run equilibrium, not expansion conditions.
- A firm in a competitive industry calculates that its total revenue covers all of its explicit costs and exactly half of its implicit costs. Which of the following is true for this firm?
Answer: Its accounting profit is positive, but its economic profit is negative.
The statement 'total revenue covers all of its explicit costs' means that TR > Explicit Costs, so accounting profit (TR - Explicit Costs) is positive. Let implicit costs be IC. The part of revenue left after covering explicit costs is the accounting profit. The stem says this amount covers 'exactly half of its implicit costs'. So, Accounting Profit = 0.5 IC. Economic Profit = Accounting Profit - IC = (0.5 IC) - IC = -0.5 * IC. Since IC is positive, economic profit is negative. Thus, the firm has a positive accounting profit but a negative economic profit (an economic loss).
- A chef uses $50,000 of her personal savings to open a restaurant; these savings had been earning 5% interest annually. In its first year, the restaurant's total revenue is $200,000, and its explicit costs for food, labor, and rent are $180,000. The chef could have earned $30,000 per year working for another restaurant. What is the restaurant's economic profit in the first year?
Answer: -$12,500
First, calculate accounting profit: Total Revenue - Explicit Costs = $200,000 - $180,000 = $20,000. Next, calculate total implicit costs. These are the forgone earnings: the forgone salary ($30,000) and the forgone interest on savings (5% of $50,000 = $2,500). Total implicit costs are $30,000 + $2,500 = $32,500. Finally, economic profit is accounting profit minus implicit costs: $20,000 - $32,500 = -$12,500.
