Harvey quit his job at State University where he earned $45,000 a year. He figures his entrepreneurial talent or foregone entrepreneurial income to be $5,000 a year. To start the business, he cashed in $100,000 in bonds that earned 10 percent interest annually to buy a software company, Extreme Gaming. In the first year, the firm sold 11,000 units of software at $75 for each unit. Of the $75 per unit, $55 goes for the costs of production, packaging, marketing, employee wages and benefits, and rent on a building. The economic profits of Harvey's firm in the first year:
$160,000
In spending all his income on beer and pizza, Fred finds that the marginal utility of the last pizza he consumed is 8, and the marginal utility of the last bottle of beer is 4. The price of a bottle of beer is $1.50. If Fred has maximized his utility, the price of pizza must be:
$3.00
Refer to the table and information. The fixed cost of the firm is $500. The firm's total variable cost is indicated in the table. The average variable cost of the firm when 5 units of output are produced is:
$400
Refer to the table and information. The fixed cost of the firm is $500. The firm's total variable cost is indicated in the table. The average total cost of the firm when 3 units of output are being produced is:
$500

Refer to the diagram and assume that price increases from $2 to $10. The coefficient of the price elasticity of supply (midpoint formula) relating to this price change is about:
0.25 and supply is inelastic
Refer to the diagram and assume a single good. If the price of the good increased from $5.70 to $6.30 along D1, the price elasticity of demand along this portion of the demand curve would be:
1.2
Suppose the price of local cable TV service increased from $16.20 to $19.80 and as a result the number of cable subscribers decreased from 224,000 to 176,000. Along this portion of the demand curve, price elasticity of demand is:
1.2
A child is given $1 of pocket money to be spent on either hard candies or chocolates. Chocolates cost 10 cents and hard candies 20 cents each. The marginal utilities derived from each product are as in the table. Which combination should be bought with the $1 to maximize total utility?
2 chocolates and 4 hard candies
Refer to the table. What is the marginal utility of the fourth unit?
44
A child is given $1 of pocket money to be spent on either hard candies or chocolates. Chocolates cost 10 cents and hard candies 20 cents each. The marginal utilities derived from each product are as in the table. What will total utility be when the consumer purchases the utility-maximizing combination of products?
620
Refer to the graph showing the marginal product (MPL) and the average product of labor (APL). At which quantity of labor employed does diminishing marginal returns set in?
B
Which type of goods is most adversely affected by recessions?
Goods for which the income elasticity coefficient is relatively high and positive
After eating four slices of pizza, you are offered a fifth slice. You turn down the slice. Your refusal indicates that the:
Marginal utility is positive for the fourth slice and negative for the fifth slice
A consumer with a fixed income will maximize utility when each good is purchased in amounts such that the:
Marginal utility per dollar spent is the same for all goods
Total utility is best defined by which of the following?
The total satisfaction received from consuming a particular amount of a product
Which of the following defines marginal utility?
The additional satisfaction received from consuming one more unit of a product
Which situation is consistent with the law of diminishing marginal utility?
The more pizza Henry eats, the less he enjoys an additional slice
The main determinant of elasticity of supply is the:
amount of time the producer has to adjust inputs in response to a price change
Suppose we find that the price elasticity of demand for a product is 3.5 when its price is increased by 2 percent. We can conclude that quantity demanded:
decreased by 7 percent
If long-run average total cost decreases as output increases, this is due to:
economies of scale
The larger the positive cross elasticity coefficient of demand between products X and Y, the:
greater their substitutability
The main difference between the short run and the long run is that:
in the short run, some inputs are fixed
Marginal product of labor refers to the:
increase in output resulting from employing one more labor
The price elasticity of supply measures how:
responsive the quantity supplied of X is to changes in the price of X
A manufacturer of frozen pizzas found that total revenue decreased when price was lowered from $5 to $4. It was also found that total revenue decreased when price was raised from $5 to $6. Thus,:
the demand for pizza is elastic above $5 and inelastic below $5
Cross elasticity of demand measures how sensitive purchases of a specific product are to changes in:
the price of some other product
The concept of price elasticity of demand measures:
the sensitivity of consumer purchases to price changes
