those goods in which other nations have a comparative advantage
Suppose that in the United States, producing an aircraft takes 10,000 hours of labor and producing a shirt takes 2 hours of labor. In China, producing an aircraft takes 40,000 hours of labor, while producing a shirt takes 4 hours of labor. What will these nations trade?
China will export shirts, while the United States will export aircraft.
Kayla can cook dinner in 30 minutes and wash the laundry in 20 minutes. Her roommate takes half as long to do each task. How should the roommates allocate the work?
There are no gains from trade in this situation.
Emilio buys pizza for $10 and soda for $2. He has income of $100.
The price of pizza rises to $20, the price of soda rises to $4, and his income rises to $400.
At any point on an indifference curve, the slope of the curve measures the consumer’s
willingness to trade one good for the other.
Matthew and Susan are both optimizing consumers in the markets for shirts and hats, where they pay $100 for a shirt and $50 for a hat. Matthew buys 4 shirts and 16 hats, while Susan buys 6 shirts and 12 hats. From this information, we can infer that Matthew’s marginal rate of substitution is _____ hats per shirt, while Susan’s is _____.
2, 2
Darius buys only lobster and chicken. Lobster is a normal good, while chicken is an inferior good. When the price of lobster rises, Darius buys
less lobster and more chicken.
If the price of pasta increases and a consumer buys more pasta, we can infer that
pasta is an inferior good, and the income effect is greater than the substitution effect.
The labor supply curve slopes upward if
the substitution effect on leisure is greater than the income effect.
Xavier opens up a lemonade stand for two hours. He spends $10 for ingredients and sells $60 worth of lemonade. In the same two hours, he could have mowed his neighbor’s lawn for $40. Xavier has an accounting profit of _____ and an economic profit of ____.
$50, $10
Diminishing marginal product explains why, as a firm’s output increases,
the production function gets flatter, while the total cost curve gets steeper.
A firm is producing 1,000 units at a total cost of $5,000. If it were to increase production to 1,001 units, its total cost would rise to $5,008. What does this information tell you about the firm?
Marginal cost is $8, and average total cost is $5.
A firm is producing 20 units with an average total cost of $25 and marginal cost of $15. If the firm were to increase production to 21 units, which of the following must occur?
Average total cost would decrease.

If a higher level of production allows workers to specialize in particular tasks, a firm will likely exhibit ________ of scale and ________ average total cost.
economies, falling
A perfectly competitive firm
takes its price as given by market conditions.
A competitive firm maximizes profit by choosing the quantity at which
marginal cost equals the price.
A competitive firm’s short-run supply curve is its ________ cost curve above its ________ cost curve.
marginal, average variable
If a profit-maximizing, competitive firm is producing a quantity at which marginal cost is between average variable cost and average total cost, it will
keep producing in the short run but exit the market in the long run.
In the long-run equilibrium of a competitive market with identical firms, what is the relationship between price marginal cost and average total cost?
P=MC and P=ATC
Pretzel stands in New York City are a perfectly competitive industry in long-run equilibrium. One day, the city starts imposing a $100 per month tax on each stand. How does this policy affect the number of pretzels consumed in the short run and the long run?
no change in the short run, down in the long run
A change in which of the following will not shift the demand curve for hamburgers?
