Q 1.

An organization has the power to increase and decries the price and supply of the product or service in monopoly. The organization also has the ability to increase and decrease the demand by the fluctuation in the price. This ability of the organization is a market power of the organization. The concept of the elasticity measures the supply and demand of the product or service by the change in the price (Söderholm and Wårell, 2011). The elasticity also provides the response to demand and supply by the change in the price where other things should remain same.

Both water supply and landline Telephone Company have a high cost of the network to provide the service. Water is a basic need or necessary thing for the human being, so it can be said that water supply organization has a greater market power than landline Telephone Company. The company has a power of reducing the supply of water that can affect the daily life of people. On the other hand, if the telephone company restricts the service for some time it does not high impact on the people. There is no high impact of the small change in the price of the water and landline to the public but water supply can affect the daily life of the people.

Q 2.

The market structure of the KFC, MacDonald’s and Hungry Jack have the oligopoly market structure. The oligopoly market structure described the few seller’s market and they provide some differentiated products and services. There is a small number of the large seller in the fast food industry that dominates the market (Wallis, et al., 2010). The entire sellers have high market share and restrict the new competitors in the market. It is because there is a need of high investment with the effective and homogeneous products. The KFC, MacDonald’s and Hungry Jack is known for small profit by the use of cost leadership market. They are offering the basic fast food meals in the restaurants at the low price to attract the customers.


Figure- Firm in Oligopolistic Market

In this industry, the firms are interdependent in the price of the competitors and always keep eyes on the strategy of competitors to survive in the competition. Each firm advertises their products to attract the customer in the oligopoly market structure. The figure shows that each firm faces two demand curves according to the kinked‐demand theory. It is because the oligopoly situation increases the competition in the market (Liu, and Wu, 2012). The demand curve becomes highly elastic if prices are increased more than profit level because consumers do not prefer the very high price in the oligopoly market situation.

Q 3.

The Charles Darwin University is facing the competition between the Darwin and Sydney campus. The level of the composition is monopolistic because the university is providing the similar services (homogeneous product) both the places. The campus at Darwin is providing the high price of the courses that affect the student. In this competitive market, the students compare the price with the other universities and can choose other campuses in Darwin due to rise in the price. The demand curve of the Charles Darwin University is sloping downward due to high price. The distance courses and extracurricular activities differentiate the university but the price restricts the enrollment of the students. The sloping downward demand curve is indicating to the university that they should restrict on the increasing price. At the same time, the price may quite high from competitors but it should be affordable to the students (Barnett, 2011). The different universities are present in overall Australia that indicates an elastic demand. The brand loyalty can also solve the problem of Charles Darwin University, where it can increase the advertisement at Darwin location. The campus can maximize the profit by achieving the level of the output.

Q 4.

The price elasticity of demand is a relationship between the price and demand that reflects the proportion change in the quantity demanded by the proportion change in price. In this case, if the fire emergency service will be provided by the any private organization than the price elasticity of demand will be inelastic in Australia. The main cause of inelastic demand is the public do not have any substitute for this service. The change in price will not effect on the demand because there is no any other substitute of fire emergency service (Ishida, et al., 2011). So, it can be said that the number of substitute increases the elasticity of the demand in the market.


Figure- Price Inelastic Demand

In addition to this, inelastic demand is also helpful to the firm because it increase the revenue by increase in the price of the fire service. The following diagram is showing the price and revenue of the firm.

Q 5.

In this unit, monopoly and monopolistic competition are used. The monopoly competition is a market situation where a firm has full control on the price and supply of the product and service. The goods and service do not have any substitute in the monopoly. The firm is a price maker in the market and does not change pricing decisions (Twomey and Neuhoff, 2010). Mostly, the monopolist increases the price of the product but in the case of lower costing condition, he can decrease the price of the product. The monopolist do not has any competitor in the marketplace.

The monopolistic competition is a kind of imperfect competition. In this competition, there are many producer of product but they differentiated the product from other competitors. In addition, the product is not a perfect substitute of the given product because it has a change in taste or quality. There is no any single business who control on the market price. Cost curve and demand curve are being identical under this competition. If some firms produce the similar products in the market then the market lead to be an oligopolistic market situation. The demand of the goods and services are highly elastic in monopolistic competition. So, if any producer small changes a price it provides high response (Janssen, et al., 2011). In short-run, the firm can earn high profit in the monopolistic competition. The new entrance is very easy in this competition.

In the concern of the Australian market, the monopolistic competition is most realistic model that provides advantages to the buyers and seller. In the Australian market, the firm can easily enter in the market and differentiate the product with the competitor. Additionally, the firms also offers new product to the people for command in the market (Alderighi, et al., 2012). But in the long run, most of the firms can earn normal profit due to close substitute of the product.

Q 6.

The Charles Darwin University will be impacted by the increase in the pass marks of the students. The student enrollment will be decrease because the demand of the passing marks has inverse relation with the enrolment. The demand curve will slop downward due to negative relationship between the enrolments and pass marks. There is no price factor that affects the demand curve, the demand will affected by the increase in price (Hunt, 2011). The university should not change the pass marks, otherwise the students will enroll in another university.

Q 7.

  1. The marginal cost curve represents the relationship between the marginal cost and quantity of output. The graphically representation of the slop of the marginal cost curve is showing downward in the starting. After increase in the productivity the marginal cost decreases at the point but regular increment can increase the marginal cost at high level. The overall marginal cost shows the U-shape.

Figure- Marginal cost curve

The marginal cost is linked with the opportunity cost because it refers to the cost of single unit that is increased in productivity (Ionescu, 2011). The opportunity cost helps to the organization because it scarifies the highest cost unit of the production. The opportunity cost is that cost which is saved by the firm by reduction in the production of one or more unit that has high marginal cost.

The concept of the marginal cost is important in the economics because it defines the cost addition in production units. Marginal cost is very important for a firm because it helps the firm to take the production related decision. In addition, it represents the cost of increases in the productivity by a single unit. The marginal cost affects on the total cost, if the marginal cost increases the total cost will also increase. The marginal cost also help the firm to develop an effective pricing policy and used in the cost and benefit analysis of the firm.

The marginal cost can be calculated by the change cost divided by the change in price. So, the marginal cost of adding an additional unit of household in the NBN network will change in the opportunity cost (Kufel-Gajda, 2017). The opportunity cost will rise due to increase in the quantity of production. The marginal cost of the household will be high than last unit added.

Q 8.

The success of the supermarket is done by the contribution of oligopoly market structure. The supermarket provides many different products at low price to the customers. The oligopoly market structure provided an imperfect competition by differentiating the products and customer use the different products from the supermarket. The supermarket has a large portion in the share market of the different firms. The price cutting is the good method that is used by the supermarkets to attract the customer of oligopoly firms (Schmidt, et al., 2014). The supermarkets do not concentrate on the increase price and they always compete on the pricing strategy and decrease the price of rivals firm.
