Exam 21: The Theory of Consumer Choice

Figure 21-24 The figure shows three indifference curves and a budget constraint for a certain consumer named Steve. -Refer to Figure 21-24. At his optimum, Steve is buying

When considering household savings, the relative price between consuming when young and consuming when old is the

Suppose the price of good X falls. As a result, the quantity demanded for good X increases for a particular consumer. For this consumer, the substitution effect induced the consumer to purchase more X while the income effect induced the consumer to purchase less X. We can infer that X is a(n)

When two goods are perfect complements, the indifference curves are right angles.

The direction of the substitution effect is not influenced by whether the good is normal or inferior.

Suppose a consumer spends her income on two goods: music CDs and DVDs. The consumer has $200 to allocate to these two goods, the price of a CD is $10, and the price of a DVD is $20. What is the maximum number of CDs the consumer can purchase?

Figure 21-15 On the graph, Q_x represents the quantity of good x and Q_y represents the quantity of good y. The lines drawn on the graph represent three of Barbara's indifference curves. -Refer to Figure 21-15. For Barbara, the marginal rate of substitution between goods y And x

Suppose a consumer has an income of $800 per month and that she spends her entire income each month on beer and bratwurst. The price of a pint of beer is $5, and the price of a bratwurst is $4. Which of the following combinations of beers and bratwursts represents a point that would lie to the exterior of the consumer's budget constraint?

The substitution effect of a price change is depicted by a

Suppose an individual is choosing between Netflix and Redbox movies. He has $16 a month to spend on movies. The price of a Redbox movie is $1 while Netflix offers unlimited movies for a monthly fee of $8. Which of the following represents this individual's budget line?

Figure 21-15 On the graph, Q_x represents the quantity of good x and Q_y represents the quantity of good y. The lines drawn on the graph represent three of Barbara's indifference curves. -Refer to Figure 21-15. Barbara is happier at

Figure 21-23 -Refer to Figure 21-23. When the price of X is $80, the price of Y is $20, and the consumer's income is $160, the consumer's optimal choice is D. Then the price of X decreases to $20. The substitution effect can be illustrated as the movement from

If Chad's labor-supply curve is upward-sloping, then, for Chad,

Higher indifference curves are preferred to lower ones as long as the

Scenario 21-3 Scott knows that he will ultimately face retirement. Assume that Scott will experience two periods in his life, one in which he works and earns income, and one in which he is retired and earns no income. Scott can earn $250,000 during his working period and nothing in his retirement period. He must both save and consume in his work period with an interest rate of 10 percent on savings. -Refer to Scenario 21-3. If the interest rate on savings increases,

Mark spends his weekly income on gin and cocktail olives. The price of gin has risen from $7 to $9 per bottle, the price of cocktail olives has fallen from $6 to $5 per jar, and Mark's income has stayed fixed at $46 per week. If you measure gin on the vertical axis and cocktail olives on the horizontal axis, then the budget constraint

A consumer maximizes utility when she consumes at a point where​

Figure 21-2 The downward-sloping line on the figure represents a consumer's budget constraint. -Refer to Figure 21-2. If the consumer's income is $100, then what is the price of an apple?

A family on a trip budgets $1,000 for meals and gasoline. If the price of a meal for the family is $50 and if gasoline costs $3.50 per gallon, then how many meals can the family buy if they buy 100 gallons of gasoline?

Is it possible for a normal good to be a Giffen good? Briefly explain.
