Exam 21: The Theory of Consumer Choice

Figure 21-30 The graph shows two budget constraints for a consumer. -Refer to Figure 21-30. Suppose the price of a light bulb is $3 and Budget Constraint B applies. What is the consumer's income? What is the price of a hamburger?

If a consumer purchases more of good X and good Y after her income increases, then neither good X nor good Y is an inferior good for her.

Figure 21-25 The figure pertains to a particular consumer. On the axes, X represents the quantity of good X and Y represents the quantity of good Y. -Refer to Figure 21-25. Suppose the price of good X is $10, the price of good Y is $5, and the consumer's income is $210. Then the consumer's optimal choice is to buy

A consumer's budget constraint is drawn with the quantity of pizza measured along the horizontal axis and the price of Pepsi measured along the vertical axis. If the market is offering the consumer the trade-off of 3 pints of Pepsi for 1 pizza, then what is the slope of the consumer's budget constraint?

Figure 21-5 (a) (b) -Refer to Figure 21-5. In graph (a), what is the price of good Y relative to the price of good X (i.e., Py/Px)?

The indifference curves for left shoes and right shoes are right angles.

A consumer has preferences over consumption and leisure, both of which are normal goods. When the wage decreases, the consumer chooses to consume less leisure. For this consumer the labor supply curve will

The substitution effect from an increase in wages is evident in a

Figure 21-17 -Refer to Figure 21-17. When the price of X is $6, the price of Y is $24, and income is $48, Paul's optimal choice is point C. Then the price of Y decreases to $6. Paul's new optimal choice is point

The theory of consumer choice illustrates the

Figure 21-32 The figure shows three indifference curves and a budget constraint for a consumer named Hannah. When young, Hannah works and earns income. When old, she is retired and earns no income. -Refer to Figure 21-32. If Hannah chose to spend $30,000 on consumption when young, then how much could she spend on consumption when old?

Gerald 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 Gerald's income has stayed fixed at $46 per week. Since the price changes, Gerald has been buying 4 bottles of gin and 2 jars of cocktail olives per week. At the original prices, 4 bottles of gin and 2 jars of cocktail olives would have

The change in consumption that results when a price change moves the consumer along a given indifference curve to a point illustrating the new marginal rate of substitution is called the

Suppose a consumer spends her income on two goods: iTunes music downloads and books. The consumer has $100 to allocate to these two goods, the price of a downloaded song is $1, and the price of a book is $20. What is the maximum number of books the consumer can purchase?

Teresa faces prices of $6.00 for a unit of good X and $1.50 for a unit of good Y. At her optimum, Teresa is willing to give up 1 unit of good X for units of good Y.

Figure 21-20 The following graph illustrates a representative consumer's preferences for marshmallows and chocolate chip cookies: -Refer to Figure 21-20. Assume that the consumer depicted the figure has an income of $50. Based on the information available in the graph, which of the following price-quantity combinations would be on her demand curve for chocolate chips if the price of marshmallows is $2.50?

When a consumer is purchasing the best combination of two goods, X and Y, subject to a budget constraint, we say that the consumer is at an optimal choice point. A graph of an optimal choice point shows that it occurs

If consumers purchase more of a good when their income rises, the good is a normal good.

Figure 21-18 -Refer to Figure 21-18. Bundle D represents a point where

If the interest rate rises, an individual could choose to
