    Multiple Choice Review Questions

    • Question 1: Individuals own small businesses primarily due to the expectation of profit, not because they can't find work elsewhere or for gaining experience.

    • Question 3: Explicit costs are the actual monetary payments made for resources used to produce a good, including payments to entrepreneurs.

    • Question 4: Economic profit is the difference between total revenues and total economic costs, which encompass both explicit and implicit costs.

    • Question 5: The return on the next best alternative investment opportunity should not be included when calculating accounting profit.

    • Question 6: Accounting profit is the difference between total revenue (4,000)andtotalexplicitcosts(4,000) and total explicit costs (4,000)andtotalexplicitcosts(1,200 + 750+750 + 750+250 + 200+200 + 200+600 + 75).Thisequals75). This equals 75).Thisequals1,525.

    • Question 7: Adam Weed's accounting profit is 250,000−250,000 - 250,000−175,000 which equals 75,000.Hiseconomicprofitiscalculatedbysubtractingoutthe75,000. His economic profit is calculated by subtracting out the 75,000.Hiseconomicprofitiscalculatedbysubtractingoutthe75,000 he could be earning elsewhere which equals a negative $0 economic profit.

    • Question 8: The firm's total economic costs are 90,000plus90,000 plus 90,000plus200000 + 75000+75000 + 75000+30000 + 35000whichequals35000 which equals 35000whichequals450,000.

    • Question 10: Perfectly competitive markets are characterized by low barriers to entry, many firms, and identical products. Large advertising budgets are not characteristic.

    • Question 11: Monopolies have the most market power of the given options.

    • Question 12: In a competitive market, no single firm can affect the market price because their output is insignificant compared to the overall market.

    • Question 14: Production decisions involve determining the quantity of output, not choosing to enter/exit the market or merging with competitors.

    • Question 15: In a perfectly competitive market, the price is constant at all output levels, meaning the total revenue curve is a straight line with a positive slope.

    • Question 16: A firm maximizes profit by setting output where marginal revenue (MR) equals marginal cost (MC).

    • Question 17: Diminishing returns cause each additional unit produced to cost increasingly more.

    • Question 18: A rising total revenue curve implies a constant price; as output increases, Total Revenue also increases in proportion to quantity.

    • Question 19: Price equals marginal revenue in a perfectly competitive market.

    • Question 20: If marginal cost exceeds price, a perfectly competitive firm should reduce output to increase profit.

    • Question 21: The profit-maximizing quantity of output for a perfectly competitive firm occurs at the point where marginal cost (MC) equals price.

    • Question 22: If the market price is 10andaveragevariablecost(AVC)isbelow10 and average variable cost (AVC) is below 10andaveragevariablecost(AVC)isbelow10, the firm should continue operating if the price covers its variable costs to minimize losses.

    • Question 23: The law of diminishing returns typically takes effect at an output quantity near the midpoint of the relevant range.

    • Question 24: In the short run a perfectly competitive firm should continue operating as long as price exceeds average variable cost.

    • Question 25: Production/investment decision is about expansion/start up decisions.

    • Question 26: A long-run decision is a business investment such as a new factory.

    • Question 27: Changes in profit taxes, payroll taxes, and inflation will impact the optimal level of output.

    • Question 28: Changes in property, profit or payroll taxes directly impact costs and both average and marginal costs.
