If the price of one good increases while the price of the other good and the consumer’s
income remain unchanged, what will happen to the budget line?
The budget line shifts inward without a change in slope.
The budget line rotates outward from the intercept on the axis of the good that did
not change in price.
The budget line rotates inward from the intercept on the axis of the good that did
not change in price.
The budget line shifts outward without a change in slope.
A perfect price discriminating equilibrium maximizes
consumer surplus.
the associated deadweight loss.

Clifford lives by the motto “Eat, drink and be merry today, for tomorrow doesn't
matter.” If today's consumption is measured on the horizontal axis and tomorrow's
consumption is measured on the vertical axis, Clifford's indifference curves
are horizontal straight lines.

show decreasing utility as one moves upward.
cannot be determined from the information given.
The below figure shows Larry’s indifference map and budget lines for ham and pork.
Which of the following statements is TRUE?
Larry’s Engel curve for pork will be upward sloping.
Larry’s Engel curve for pork will be downward sloping.
Larry’s Engel curve for pork will be backward bending.
Larry’s Engel curve for pork cannot be derived from the information provided.
At an output level of 100 a monopolist faces MC=15 and MR=17. At output level
q=101 the monopolists MC=16 and MR=15. To maximize profits the firm
should produce 100 units.
should produce 101 units.
cannot maximize profits.
is not a monopoly.
If the inverse demand curve a monopoly faces is p=100−2Q, and MC is constant at 16,
then the deadweight loss from monopoly equals
$21
$1,764
$882
$441
If consumers are identical, then
price discrimination is impossible.
price discrimination can occur if each consumer has a downward-sloping demand
curve for the product.
perfect price discrimination is the only form of price discrimination that can
increase a monopoly’s profit.
tie-in sales cannot increase a monopoly’s profit.
Quantity discrimination makes sense if
buyers of smaller quantities are more price sensitive than buyers of larger
quantities.
buyers of smaller quantities are less price sensitive than buyers of larger quantities.
demand for the good is perfectly elastic.
the lower price for larger quantities encourages all consumers to purchase the larger
quantity.
Perfect competition and monopolistic competition are similar in that firms in both types
of market structure will
act as price takers
produce a level of output where price equals marginal cost.
earn zero profit in the long run.
act as price setters.
The concept of Nash equilibrium states that
no firm can improve their outcome holding the other firm’s actions constant
all firms are earning the highest possible profit
firms make alternating output decisions

Suppose two Cournot duopolist firms operate at zero marginal cost. The market
demand is P = a − bQ , Q= q1 + q2 , q1and q2 are firm 1 and firm 2′s quantity
respectively. Firm 1′s best-response function is
q1 = (2a - bq2 )/2b
q1 = (a - 2bq2 )/b
q1 = (a - bq2 )/2b
q1 = ( aq2 )/2b
If fair insurance is offered to a risk-averse person, she will
not buy any insurance since the marginal utility of the amount of the payment is
positive.
not buy any insurance because it is overpriced.
buy enough insurance to eliminate all risk.
buy enough insurance to cover about half of the possible loss.
According to Keynesian theory, when real GDP is
either above or below potential GDP, prices and wages change rapidly, and return
the economy to full employment.
above potential GDP, prices and wages rise very slowly, and return the economy to
full employment.
below potential GDP, prices and wages rise very slowly, and return the economy to
full employment.
None of the above answers are correct.

An increase in the price level.
An increase in investment.
A decrease in taxes.
All of the following contribute to raising real wages over time EXCEPT
technological progress.
rising labor force participation.

EXCEPT a
business’s purchase of a fleet of cars.

Read the two statements below and indicate if they are true or false.
I. Autonomous expenditures change when GDP changes.
II. Aggregate planned expenditure is the sum of planned consumption expenditure,
investment, government purchases, and net exports.
I and II are both true.
I and II are both false.
I is false and II is true.
I is true and II is false.
In the below table, C is consumption expenditure, I is investment, G is government
purchases, X is exports, and M is imports. All entries are in dollars. If investment were
to increase by $26 to a level of $51 then equilibrium expenditure will
increase by $25
increase by $100
decrease by $50
decrease by $100.
