3. Profit maximization using total cost and total revenue curves
Suppose Darnell runs a small business that manufactures shirts. Assume that the market for shirts is a competitive market, and the market price is $20 per shirt.
The following graph shows Darnell's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Darnell produces.

Calculate Darnell's marginal revenue and marginal cost for the first seven shirts he produces, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.

Darnell's profit is maximized when he produces _______ shirts. When he does this, the marginal cost of the last shirt he produces is _______ , which is_______ than the price Darnell receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is _______ . which is _______ than the price Darnell receives for each shirt he sells. Therefore, Darnell's profit- maximizing quantity corresponds to the intersection of the ______________ curves. Because Darnell is a price taker, this last condition can also be written as _______ .

Suppose Raphael runs a small business that manufactures frying pans. Assume that the market for frying pans is a competitive market, and the
market price is $20 per frying pan.
The following graph shows Raphael's total cost curve.
Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for frying pans quantities zero through seven (inclusive) that Raphael produces.

Calculate Raphael's marginal revenue and marginal cost for the first seven frying pans he produces, and plot them on the following graph. Use the blue points (circle symbol) to plot marginal revenue and the orange points (square symbol) to plot marginal cost at each quantity.

Raphael's profit is maximized when he produces _______ frying pans. When he does this, the marginal cost of the last frying pan he produces is _______ which is _______ than the price Raphael receives for each frying pan he sells. The marginal cost of producing an additional frying pan
(that is, one more frying pan than would maximize his profit) is _______ .which is _______ than the price Raphael receives for each frying pan
he sells. Therefore, Raphael's profit-maximizing quantity corresponds to the intersection of the ______________ curves.

Cigarettes have long been subject to excise tax – a per cigarette tax levied on the suppliers of cigarettes. (The tax applies to all tobacco products, however for the purposes of this exam assume cigarette and tobacco consumption are the same thing). In 2016 the federal government announced that the excise tax rate for cigarettes would rise by 12.5% a year for the next 4 years. Over this period tax revenue collected from the sale of cigarettes has increased considerably. Legal cigarette consumption has fallen to an all-time low in Australia due to a combination of the tax on cigarettes, and public health initiatives such as plain packaging, health warnings and banning advertisements.
Consider the following two policies aimed at reducing cigarette smoking: (i) A tax on the suppliers of cigarettes, and (ii) The public health campaign initiatives. Illustrate both of these policies separately using a fully labelled and explained demand and supply diagram for each of parts (i) and (ii). Do not use actual numbers; this is intended as a theoretical exercise. Compare and contrast the impact on equilibrium price and quantity of cigarettes of each of these policies, explaining your answer with reference to the diagrams. Consider the impact of each policy on government revenue. Explain your answer. Can the impact on government revenue be illustrated on either of your diagrams? If so, indicate and explain the area on the diagram/s that represents government revenue.

Question text
Which of the following statement(s) is correct?
(x) Deadweight loss measures the loss in a market to buyers and sellers that is not offset by an increase in government revenue.
(y) The imposition of a tax on a good raises the price that buyers effectively pay, but lowers the price that sellers effectively keep.
(z) When the government places a tax on a good, the loss of consumer surplus and producer surplus to buyers and sellers is more than the tax revenue raised from the imposition of the tax.
Select one:
A. (x), (y) and (z)
B. (x) and (y) only
C. (x) and (z) only
D. (x) and (y) only
E. (y) only
Which of the following statement(s) is correct?
(x) Assume that the demand for food is relatively inelastic and the demand for jewelry is relatively elastic. Suppose government imposed the same excise tax on both goods. As a result, the tax revenue from the tax on jewelry will always be less than the tax revenue from the tax on food.
(y) Taxes cause deadweight losses because they prevent buyers and sellers from realizing some of the gains from trade due to marginal buyers and sellers leaving the market.
(z) The deadweight loss from taxes is lower when tax rates are higher than when tax rates are lower.

A. (x), (y) and (z)

46. In terms of “market power” which of the below is correct, going from the firms with the most to the least “market power’? (Hint: envision the “level of competition” spectrum)
oligopoly, monopoly, perfect competition, monopolistic competition
monopoly, oligopoly, monopolistic competition, perfect competition
perfect competition, monopolistic competition, oligopoly, monopoly
monopolistic competition, monopoly, oligopoly, perfect competition
43. A cartel is (e.g. OPEC )
an agreement among rival firms to set prices independently
a group of monopolistically competitive firms which charge the same price
a group of oligopolistic firms that engage in formal collusion
a group of oligopolistic firms that engage in informal collusion
33. In the long run, a monopolist
will shut-down if it is incurring economic losses
earns a normal profit because other firms can easily enter the market
always earns an economic profit because of the existence of barriers to entry
can earn an economic profit because of the existence of barriers to entry
32. A monopolist will likely shut down in the short run if
price is less than average total cost (ATC)
price is less than average variable cost (AVC)
marginal revenue is less than AVC
price is less than average variable cost (AVC) and marginal revenue is less than AVC because for the monopolist, price = marginal revenue
marginal revenue is less than ATC
