c.is the maximum amount a buyer is willing to pay minus the minimum amount a seller
is willing to accept.
d.is the amount a buyer is willing to pay for a good minus the amount the buyer actually
pays for it.
2) When quantity demanded increases at every possible price, the demand curve has
a.shifted to the left.
b.shifted to the right.
c.not shifted; rather, we have moved along the demand curve to a new point on the
same curve.
d.not shifted; rather, the demand curve has become steeper.
3) Total surplus is equal to
a.value to buyers - profit to sellers.
b.value to buyers - cost to sellers.

5) If unskilled labor is relatively plentiful and cheap in many foreign countries, then as
the United States expands its trade with these foreign countries, the domestic demand
for
a.both skilled and unskilled labor will rise proportionately.
b.skilled labor will fall and the demand for unskilled labor will rise.
c.skilled labor will rise and the demand for unskilled labor will fall.

a.increases by 0.75 units.

7) A consumer has preferences over two goods, X and Y. Suppose we graph this
consumer's preferences (which satisfy the usual properties of indifference curves) and
budget constraint on a diagram with X on the horizontal axis and Y on the vertical axis.
At the consumer's current consumption bundle, the consumer is spending all available
income, and the marginal rate of substitution is greater than the slope of the budget
constraint. We can conclude that the consumer
a.is currently maximizing satisfaction subject to the budget constraint.
b.could increase satisfaction by consuming more X and less Y.
c.could increase satisfaction by consuming less X and more Y.
d.could purchase more X and more Y and increase total satisfaction.
8) Elephant populations in some African countries have started to rise because
a.environmentalists have developed effective educational campaigns.

b.Vietnam has a comparative advantage over other countries and Vietnam will export
textiles.
c.other countries have a comparative advantage over Vietnam and Vietnam will import
textiles.

a.marginal cost curve above its average variable cost curve.
b.marginal cost curve above its average total cost curve.
c.average variable cost curve above its marginal cost curve.
d.average total cost curve above its marginal cost curve.
