more crude oil at a higher price per barrel.

now buy more crude oil, but at a higher price per barrel.

surplus increases, while the effect on domestic consumer surplus is unclear.

recipients to purchase from a restricted set of items which may not include things that
the poor need the most such as diapers or cleaning supplies.
c.A disadvantage of minimum wage laws is that they are expensive for state and local
governments to fund.
d.Effective minimum wage laws create a surplus of labor.
3) Which of the following statements is not correct?
a.If Fiona gets a higher wage and works more, the substitution effect is greater than the
income effect for her.

than the substitution effect for him.
c.If the substitution effect is greater than the income effect, the labor-supply curve is
upward sloping.
d.If the income effect is greater than the substitution effect, the labor-supply curve is
downward sloping.

food are fairly bad¾ Mai’s skills in knitting sweaters are fairly bad, but her skills in
cooking tasty food are fairly good.
d.Howard’s skills are such that he can produce only sweaters, and Mai’s skills are such
that she can produce only tasty food.

c.diseconomies of scale.
d.an efficient use of resources.
12) For a certain firm, the 100th unit of output that the firm produces has a marginal
revenue of $7 and a marginal cost of $10. It follows that the
a.production of the 100th unit of output increases the firm‘s profit by $3.
b.production of the 100th unit of output increases the firm‘s average total cost by $7.
c.firm‘s profit-maximizing level of output is less than 100 units.

13) Firms operating in competitive markets produce output levels where marginal
revenue equals
