Answer 1
(a) Ron’s Hamburger Joint is the only restaurant in town and thus it enjoys a monopoly market
structure. Therefore, given the firm structure of Ron’s Hamburger Joint, it can be said that the
Ron maximizes profit where marginal revenue (MR) equals marginal cost (MC)1. The
intersection point between MR and MC curve gives the production of hamburgers. Therefore, as
per the give figure Ron produces 20 hamburgers per hour.
(b) Given the production of Ron, price charged per hamburger is $6. The price decision is made
from demand curve which is above the intersection point between MR and MC. This is done to
earn super normal profit.
(c) Cost for per unit of hamburger production is $4. Total amount of hamburgers produced is 20.
Therefore, total cost of Ron’s Hamburger Joint is
Total cost=Cost per Hamburger × No .of Hamburger produced
¿ , Totalcost =4 × 20
¿ , Total cost =$ 80
Similarly, given the price of hamburger and its unit of production, total revenue earned by Ron’s
Hamburger Joint is
Total Revenue=Price per Hamburger × No. of Hamburger sold
¿ , Total Revenue=6 ×20
¿ , Total Revenue=$ 120

(d) Economic profit can be calculated by subtracting total cost from total revenue. Therefore,
economic profit Ron’s Hamburger Joint is
Economic Profit=Total Revenue−Total Cost
¿ , Economic Profit=120−80

(b) From the calculation of four firm concentration ratio of 0.30, it can be said that the
concentration in the industry is 30%. It means that industry is competitive in nature as the
percentage of concentration is below 60 %.
(c) The market type of the industry is monopolistic competition as it is evident from the four firm
concentration that the largest four firms captures only 30% of the market share2. In addition to
that, fourth largest firm capture only 3%. Hence, the concentration of the market of industry is
low.
Answer 3
The Herfindahl-Hirschman Index (HHI) of the industry is
HHI =452+ 252+202 +102
¿ , HHI=2025+625+ 400+100
¿ , HHI=3150
The market type of the industry is oligopoly as the market concentration is well over
2500 as per the above calculation which indicates that the market is highly concentrated with low
competitiveness.

Answer 4
A real world example of monopolistic competition is market of restaurant industry. The
product of the restaurant industry is food but are differentiated3. With an objective to gain more
market share, every firm in the industry try to differentiate their product from the rival firms’.
For example, if one firm is offering Chinese food then to differentiate other firm offers Mexican
food. There are numerous firms in the industry like in the case of perfect competition. As the
products are differentiated there is negligible amount of market power to the firms, however, the
market power is not impactful and thus there is no barriers to entry and exit4. The firms in this
market earn zero economic profit. Thus, the characteristics of this market resembles
monopolistic competition.

from New York restaurants." (2019).
