Answer to Question 6
(A)
(Rubinfeld and Pindyck 2013)
Suppose for some exogenous reason, the demand curve increases from D1 to D2. This
will increase prices from P1 to P2. As prices increases, the profits incurring to the firms also
increases. This will lead to the entry of new firms. As there exists constant cost structure, the
cost curves will not shift. The entry of the new firms will lead to increase in supply from S1
to S2. This entry will occur until there in zero profits in the industry. Therefore, Prices
remains same and the industry output increases to Q2. The long run curve is fully elastic in
nature.
(B)
The case of increasing cost is quite different from the constant cost industry. Suppose
because of some external factor the demand in the market increases from D1 to D2. Because
of this, prices increases from P1 to P2. Thus, existing firm now enjoys supernormal profit.
This will lead to entry of new firms in the industry. Because of the increasing cost structure

of the industry, the entry of new firms will lead to increase or shift of the long-run average
cost curve. The marginal cost curve also shifts from SMC1 to SMC2. Therefore, the new
competitive equilibrium will shift to a point where prices are P3. The existing firms might
leave due to the increased costs. Therefore, the supply will increase from S1 to S2. The
equilibrium point shifts from A to B. The long-run supply curve in this case is upwards
sloping in nature dented by SL.
(Rubinfeld and Pindyck 2013)
(C)
In case of decreasing cost industry, entry of new firms will lead to a decrease in the
cost structure of the industry. Suppose that the demand curve shifts from D to D1 because of
this, there will be increase in the prices and the quantity demanded. The prices will increase
from P to P1. The existing firm will now earn a super normal profit. This will lead of new
firms in the market. However, as the cost structure suggests, entry of new firms will lead to a
decrease on the long –run average cost from LAC to LAC1. The profit maximising
equilibrium will shift from P to P2. Thus, the level of profit increases. This increases the
entry of the new firms shifting the supply curve more from than the demand from S to S1.

The equilibrium point shifts E to E1. Thus, the long-run supply curve of the industry is
downwards sloping.

Public goods are those goods, which are provided to every individual in a society, and
nobody can be excluded from rendering the services of these products. In most of the
economies, government is the provider of such public goods (Brim 2017). For example, think
of the police protection that is enjoyed by every citizen of a country. Instead of the
government if the private firms were to provide this service, then the firm would need to
identify the individuals who are using these services. Private firms are often engage in
maximising their profits unlike that of the public sector firms. Moreover, the private firms
must have perfect knowledge of the quantity of police protection that is consumed by every
individual. Further, the firm will also have to assess and keep a record of those individuals
who are not rendering these services. Because of all these issues there may exist,
inefficiencies related to the privatisation of public goods. In order to maximize efficiency the
production of the public goods must occur at the point where marginal benefit equals the
marginal cost. Therefore, the cost of providing some additional service is zero. This
phenomenon cannot be achieved by a private firm whose main concern is to maximize the
own profit.
