Executive Summary:

The economy of a country is related with the production and consumption of goods and services to the consumers and through this way maintain the balance of consumers demand and supply. The outputs produce in the firm goes to the market place to go to the final consumers. Depending on the structures of these markets, the price quality, availability, switching cost may be differed. Basically the market structures of a country define the different characteristics of a market. These characteristics can be the organizational characteristics or the competitive characteristics. The South African mobile telecom sectors sometime are in the monopoly or sometime in the oligopoly and finally in the perfectly competitive situation. The monopoly market has only one seller such as MTN but many buyers. The oligopoly market has two sellers such as MTN and Vodacom who dominate the market together and set the price by discussing between themselves. The perfectly completive market ensures different sellers and ensures the competitive price among the sellers. When the Virgin enters into the telecom sectors, the market becomes competitive. The perfectly competitive market ensures the proper allocation of resources and information to every party of the economy. It also ensures the profit maximization in the context of normal profit, super normal profit and economic loss.

Introduction:Economy of a country ensures the proper allocation of resources to the every one of the country. The different products made by the different firms in the economy are supplied to the different markets. The price nature of competition depends on the structure of the market of a nation. The South African mobile telecom sectors experienced different market structure at different time. These market structure provides different advantages or disadvantages to the both different firm and the consumers. To enter into an established market sector is so tough. But dedication and hard work can ensure the entrance of the marketplace such as the Virgin telecom in South African telecom sectors. After their seven years’ war Virgin enters into the Telecom sectors of South Africa.

Methodology:To prepare this essay a huge study is made on the microeconomics. And specially certain part such as kinked demand curve, profit maximization, market structures, different profit etc. the data used here are secondary collects from different websites, journals, books and periodicals. That means all the data are presented here are secondary. Several graphs on relevant ideas are given on this essay. Then all the collected data are documented using Microsoft word.

1.1 Market Structure of South African Mobile Telecommunication Industry:Market structure is characterized by economists as the attributes of the market. It could be hierarchical attributes or aggressive qualities or other peculiarities that can best depict a products and administrations market. The real Characteristics that economist have focused on in portraying the market structures are the way of rivalry and the mode of valuing in that market

Features of market structure: The number of firm working in a market; It will blanket both the nearby and remote

markets. The focus proportion of organization; this will demonstrate the market offer held by the

extensive organizations. The sum and nature of expenses in the market; It will demonstrate how the diverse

expenses influence the contestability in the market. It will incorporate the economies of scale and the vicinity of sunken expenses.

The level of vertical mix; Vertical reconciliation is the methodology of joining together the diverse phases of creation and appropriation to be overseen by a solitary endeavor.

the levels of item

The market structures that are existing in the South African mobile telecom industry are discussed in the following section.

of 32

Monopoly:It is a market structure described by a single seller, offering a remarkable item in the market.

A market structure described by a single seller, offering a remarkable item in the market is called imposing business model market. In a restraining infrastructure market, the seller confronts no rival, as he is the sole seller of merchandise with no nearby substitute.

In an imposing business model market, elements like government permit, responsibility for, copyright and patent and high beginning expense make an element a single seller of merchandise. All these elements confine the passage of different sellers in t

Oligopoly:Oligopoly could be characterized as a market structure with a little number of extensive players likewise called as Oligopolists. These vast players have a noteworthy offer of the aggregate market size. Colossal rivalry is focused inside these contenders

Assumptions to Oligopoly and South African Telecom In Light Of Oligopoly:

Few Sellers: There are few solid and powerful firms working in an oligopoly and are going up against one another. The other few firms working in the market are not overwhelming and have a subtle offer of the market.

Interdependence: It is one the most highlighted peculiarity of oligopoly. Reliance is as far as choice making techniques. This happens in light of the fact that, the quantity of powerful contenders is few, and the change in value or yield by any of the firm causes immediate impact on the wage of its rival

Entry and exit barriers:The barriers are high to enter and passageway the industry. It is one of the numerous reasons; firms in oligopoly have more noteworthy control inside the industry. There could be numerous barriers to enter this industry, some on account of the way of the industry and some in light of the fact that the occupant firms go about as solid divider. Telecom is an exceptionally innovation driven part. Access to the engineering normally obliges a considerable measure of venture. Responsibility for permit likewise speaks to immense section obstruction.

Homogeneous or differentiated products:There is no situated standard in an oligopoly about homogeneity or separation of the item/benefit. It fluctuates starting with one industry then into the next. In mobile telecom, the item is same.

of 32

Non price competition:The opposition in oligopoly is not limited to cost, however different perspectives that a buyer takes a gander at. This is additionally a champion gimmick of oligopoly. Non-value rivalry in telecom would incorporate rivalry over a) superior scope of system b) big name supports c) marking d) forceful promoting methods e) better client administration f) expanding into related product offering.

Ability to set price:Dissimilar to perfect competition, the prevailing firms in oligopoly have the focal point to set the price of the item. The way of oligopoly is such, that industry is the price setter as opposed to price taker.

Perfect competition:Perfect competition, as the name itself recommends, is the most competitive type of monetary structure. Unadulterated Perfect competition scarcely exists. 1. As indicated by an article [oxford journal] perfect competition implies a state of undertakings in which the interest for the yield of an individual dealer is perfectly versatile.

Assumptions to Perfect Competition:

Many buyers and sellers:Under this market structure, there are huge number of buyers and merchants of the item. Every vender is so little there is no option impact the price of the ware through a change in its price; each one firm is a price taker.

Homogeneous product:The product sold in the market is an identical (same) product. Same product is being made to be supplied in the market by every firm. The outputs can be received as a perfect substitute.

No entry or exit barriers:Not at all like the suspicion of oligopoly, does perfectly competitive not have any barriers to enter or passageway the industry. Market is interested in any firm who decides to be a merchant of the product

Perfect information:It is expected that each purchaser and each dealer in the market knows everything about the product. On the off chance that any firm charges higher price than the market price of the product, the customers will move away towards the product of different firms.

of 32

1.2 Barriers to entry exit in this industry:Barriers to entry are factors that avoid or make it troublesome for new firms to enter a market. The presences of barriers to entry make the market less contestable and less competitive. The more prominent the barriers to entry which exist, the less competitive the market will be.

In the initial level of industry barriers to entry in the market is more because there are only one or two firm dominating the market such like as MTN and Vodacom in south African mobile telecom industry. The entry barriers that can face a new firm to entry in the market such like as virgin mobile company face are given below.

Some barriers to entry exit into or from market:

Economies of Scale:Economies of scale happen when expanded yield prompts lower normal expenses. Consequently new firms, with moderately low yield, will think that it hard to contend in light of the fact that there normal expenses will be higher than the occupant firms profiting from economies of scale. The possibility of higher normal expenses may hinder entry.

A firm producing at Q1 has lower average costs. If a new firm enters and generates Q2,the average cost become uncompetitive.

Common/ Geographical Barriers: Zimbabwe has 85% of the world supply of Chromium. On the off chance that you don't have oil in your nation, you can't enter the oil market. Land barriers could be more neighborhood, e.g. in

of 32

the event that you don't have entry to a decent area for a theater in say Covent Garden, it creates an obligation to entry.

Brand Loyalty through advertising: Developing buyer dedication through establishing a solid brand picture can prevent entry. With an exceptionally solid brand picture another firm would need to use a ton of cash on advertising, which are a sunken expense and a hindrance to entry.

Breaking point Pricing: This happens when a firm sets price sufficiently low to stop entry. Syndication may participate in farthest point pricing – despite the fact that it implies less profit; it wants to keep prices lower to avoid competition. It is identified with economies of scale.

Predatory Pricing: This happens when an incumbent firm reacts to another firm entering the market by starting a price war and trying to push the adversary firm out of business. It is unlawful so it might be hard to execute in practice.

Vertical Integration: Vertical integration happens when a firm has control over the supply and appropriation of the great. Case in point, oil organizations can keep the price of petrol high to debilitate new petrol retailers.

Legitimate Patents: A legitimate patent can give an unadulterated syndication in light of the fact that other firms can't utilize its patent (e.g. a pharmaceutical organization can get a medication patent for 7 years, meaning nobody else can offer that specific medication.

Learning and expertise: Gained as a matter of fact e.g. Microsoft and Google are both built mechanical monsters. Numerous years of operating in the markets will provide for them learning and expertise. This may be troublesome for new firms to make up for lost time.

Being the first mover in the industry: In a few industries, being the first firm to get secured gives an enormous playing point. Google wasn't the first internet searcher, however now it has dominated the market and is often preinstalled on programs.

System effects: In numerous industries, the achievement of the business obliges a firm to have a discriminating mass of clients. This is especially the case with online networking. Individuals don't pick fundamentally the best specialized online networking – yet the ones their companion’s utilization.

2.1 Actions to combat potential abuse of market power:The measure of a business, even one that dominates a specific market, is not, of itself, a foundation for concern. Businesses may need to wind up substantial to attain lower production costs or to go up against outside and residential competitors. The misuse of dominant position segments of the Competition Act may apply when the greater parts of the following criteria are met:

The dominant firm or firms have market power — that is the capacity to situated prices above competitive levels.

The dominant firm or firms participate in hostile to competitive acts — business polishes that are intended to decrease competition. These practices include: buying up a competitor's customers or suppliers; using "fighting brands"

The hostile to competitive acts have considerably diminished competition, or are prone to do so. This can happen when against competitive acts eliminate an adversary or avert such things as a rival's entry into a market, potential competition, product innovation and lower prices.

The Act's ill-uses of dominant position areas don't punish an organization that has caught a dominant offer of the market as a result of its better

Some actions have already taken by the South African government to protect the misuse of market power.

1. Government provides more incentives to enter new firm into mobile telecom sectors2. Enforce flexible laws and regulations in the context of mobile telecom sector3. Discourage the practice of monopoly or oligopoly4. Reduce the infrastructure cost of telecom industry5. Encourage firm to practice perfectly competitive market6. Reduce the tax on airtime and all others services on mobile telecom7. Take proper actions to reduce the syndications

2.2 Kinked demand curve in the context of telecom sectors of South Africa:Oligopoly alludes to a market structure where an industry is dominated by a little number of extensive merchants. Since there are few members in this kind of market, every oligopolistic is mindful of the activities of the others. The choices of one firm influence, and are influenced by, the choices of other firms.

of 32

The kinked demand curve model of oligopoly in the context of South African telecom sector:

The kinked demand curve model created first by the economist Paul Sweeny accept that a business may confront a double demand curve for its item focused around the feasible responses of different firms in the market to a change in its cost or an alternate variable. The basic presumption of the hypothesis is that organizations in an oligopoly are looking to ensure and keep up their market offer and that opponent firms are unrealistic to match an alternate's cost build however may match a value fall. I.e. opponent firms inside an oligopoly respond lopsidedly to a change in the cost of an alternate firm.

In the event that a business raises cost and others leave their prices steady, then we can expect very much a vast substitution impact far from this firm making demand generally value versatile. The business would then lose market impart and hope to see a fall in its total revenue.

In the event that a business decreases cost however different firms go with the same pattern, the relative value change is much more modest and demand would be inelastic in admiration of the value change. Cutting prices when demand is inelastic additionally prompts a fall altogether revenue with next to zero impact on market offer.

The kinked demand curve model hence makes a forecast that a business may achieve a stable profit-maximizing equilibrium at value P1 and yield Q1 and have minimal impetus to modify prices.

of 32

The kinked demand curve model predicts times of relative cost security under an oligopoly with organizations concentrating on non-cost rivalry as a method for fortifying their market position and expanding their super ordinary profits.

Fleeting value wars between adversary firms can even now happen under the kinked demand curve model. Amid a value war, firms in the market are trying to grab a transient playing point and win over some additional market offer.

The necessaries of non-price rivals under oligopoly in the context of kinked demand curve:Non-price competition accepts expanded vitality in oligopoly markets. Non-price rivals entails publicizing and marketing methods to expand demand and create brand devotion among buyers. Organizations will utilize different approaches to build market offer:

Better nature of administration including ensured conveyance times for buyers and minimal effort adjusting understandings

Longer opening hours for retailers, 24 hour phone and online client help Extended guarantees on new items Discounts on item overhauls when they get to be accessible in the market Contractual associations with suppliers - for instance the arrangement of tied houses for

pubs and contractual concurrences with establishments (select dissemination understandings)

of 32

Price leadership – tacit collusion:

Another type of oligopolistic behavior is price leadership. This is when one firm has a clear dominant position in the market and the firms with lower market shares follow the pricing changes prompted by the dominant firm. Firms who market to consumers that they are “never knowingly undersold” or who claim to be monitoring and matching the cheapest price in a given geographical area are essentially engaged in tacit collusion. Tacit collusion occurs where firms undertake actions that are likely to minimize a rival response, e.g. deleting price cut or not compete in the market.

Explicit collusion under oligopoly:

It is frequently watched that when a market is ruled by a couple of substantial firms, there is dependably the potential for organizations to try to diminish market vulnerability and take part in some manifestation of conniving conduct. At the point when this happens the current firms choose to take part in price fixing assertions or cartels.

.

of 32

Collusion in a market is so easy to achieve when:1. There is just a little number of firms in the business and boundaries to entrance secure the syndication force of existing firms over the long haul.

2. Market demand is not excessively variable

3. Demand is decently inelastic concerning cost so that a higher cartel cost expands the aggregate income to suppliers in the business sector

4. Each association's yield could be effortlessly checked – this empowers the cartel all the more effectively to control aggregate supply and distinguish firms who are undermining yield shares.

Conceivable break-downs of cartels: Most cartel courses of action experience troubles and pressures and some maker cartels categorize whole. A few variables can make issues inside a tricky understanding between suppliers:

Enforcement issues: The cartel means to confine downright creation to boost aggregate profits of parts.

Falling business sector demand amid a log jam or subsidence makes abundance limit in the business and puts weight on individual firms to slice costs to keep up their income.

the fruitful entrance of non-cartel firms into the business undermines a cartel's control of the business – e.g. the development of online retailers in the book business in the

3.1 Monopolist in South African telecom before 2003:Before 2003, in South Africa only one firm were dominate the mobile telecom sector that create the monopolist situation in the South African mobile telecom sectors. After that many firms such as Virgin mobile telecom try to enter into the industry. After a long war they are retained in the competition.

Monopoly business model is a type of business sector structure of imperfect competition, predominantly portrayed by the presence of a sole vender and numerous purchasers. This sort of business is regularly connected with section and passageway obstructions.

These gimmicks give the monopolist the capability to set prices with the main constraint of customers' ability to pay. Along these lines, in imposing business models, the vender is a price-creator and purchasers will be price-takers. The firm will pick its production output (q) and price (p) to maximize revenue (π). The ideal condition, where we'll have marginal cost (MC) meets marginal revenue (MR), is given by

of 32

Types of Monopoly:

Perfect Monopoly: It is additionally called as supreme imposing business model. For this situation, there is just a solitary merchant of item having no nearby substitute; not by any means remote one. There is completely zero level of rivalry. Such imposing business model is basically exceptionally uncommon.

Imperfect Monopoly: It is likewise called as relative syndication or straightforward or restricted restraining infrastructure. It alludes to a solitary dealer market having no nearby substitute. It implies in this market, an item may have a remote substitute. In this way, there is alarm of rivalry to some degree e.g. Portable (Cellphone) telecom industry (e.g. Virgin) is having rivalry from altered landline telephone administration industry (e.g. BSNL).

of 32

Private Monopoly: At the point when creation is possessed, controlled and oversaw by the individual, or private body or private association, it is called private imposing business model. e.g. Tata, Reliance, Bajaj, and so forth aggregates in India. Such sort of imposing business model is benefit arranged.

Public Monopoly: At the point when generation is claimed, controlled and oversaw by government, it is called open imposing business model. It is welfare and administration turned. In this way, it is additionally called as 'Welfare Monopoly' e.g. Tracks, Defense, and so on.

Straightforward Monopoly: Straightforward imposing business model firm charges an uniform value or single cost to all the clients. He works in a solitary market.

Separating Monopoly: Such a syndication firm charges diverse cost to distinctive clients for the same item. It wins in more than one market.

Legitimate Monopoly: At the point when imposing business model exists because of trademarks, licenses, duplicate rights, statutory regulation of government and so on., it is called legitimate restraining infrastructure. Music industry is a case of legitimate imposing business model.

Natural Monopoly: It develops as an aftereffect of common points of interest like great area, copious mineral assets, and so on e.g. Bay nations are having imposing business model in unrefined petroleum investigation.

Joint Monopoly: Various business firms gain restraining infrastructure position through amalgamation, cartels, syndicates, and so forth it gets to be joint syndication

Engineering Monopoly: It develops as an aftereffect of economies of extensive scale creation, utilization of capital products, new generation techniques, and so forth e.g. Designing merchandise industry, auto industry, programming industry, and so forth.

Monopoly, Characteristics:The main characteristics of monopoly market structure are given below.

of 32

Single Supplier:The quintessence of an imposing business model is a business controlled by a solitary merchant. The single vender, obviously, is an immediate complexity to flawless rivalry, which has countless. The most vital part of being a solitary dealer is that the syndication merchant IS the business sector. The business sector demand for a decent IS the demand for the yield delivered by the restraining infrastructure.

Unique Product:To be the main dealer of an item, nonetheless, an imposing business model must have an extraordinary item.

Obstructions to Entry and Exit:Syndication is by and large guaranteed of being the ONLY firm in a business sector due to grouped boundaries to entrance. A portion of the key hindrances to entrance are: (1) legislature permit or establishment, (2) asset possession, (3) licenses and copyrights, (4) high start-up expense, and (5) diminishing normal total expense.

Specific Information:Restraining infrastructure is regularly portrayed by control of data or generation innovation not accessible to others. This particular data frequently comes as lawfully settled licenses, copyrights, or trademarks. While these make lawful obstructions to passage they additionally show that data is not splendidly imparted by all.

Advantages and Disadvantages of a Monopoly MarketA monopoly market exists when there is enormous number of purchasers yet little or exceptionally predetermined number of dealers in the market. Like another market structure a monopoly market has its points of interest and disservices to both the purchaser and the vender.

Advantages:

Steadiness of prices: In a monopoly market the prices are the vast majority of the times stable. This happens on the grounds that there is stand out firm included in the market that sets the prices if and when it feels like

Wellspring of income for the legislature: The legislature gets income in manifestation of tariff from monopoly firms.

Monstrous profits: Because of the unlucky deficiency of contenders which prompts high number of offers monopoly firms have a tendency to get super profits from their operations.

of 32

Monopoly firms offer a few administrations viably and proficiently.

Disadvantages:

Exploitation of consumers: A monopoly market is best known for consumer exploitation. There are in reality no contending products and accordingly the consumer gets a crude arrangement as far as amount, quality and estimating.

Dissatisfied consumers:Consumers get a crude arrangement from a monopoly market in light of the fact that quality will be traded off. Therefore it is not a wonder to see extremely disappointed consumers who often grumble about the company's products

Higher prices: No competition in the market implies unlucky deficiency of such things as value wars that may have profited the consumer and as an aftereffect of this monopoly firms have a tendency to charge higher prices on goods and services henceforth inconveniencing the purchaser.

Price discrimination: Monopoly firms are additionally once in a while known for drilling value discrimination where they charge different prices on the same product for different consumers.

Inferior goods and services:Competition is insignificant or completely truant and thusly the monopoly firm may energetically deliver substandard goods and services on the grounds that after all they know the goods won't neglect to offer.

3.2 Benefits of perfect competition:A perfectly competitive market is a theoretical market where rivalry is grinding way’s most noteworthy conceivable level. Neo-traditional economists contended that flawless rivalry would deliver the best conceivable results for shoppers, and society.

Perfectly competitive markets exhibit the following characteristics: There is impeccable learning, with no data disappointment or time slacks. There are no

obstructions to section into or passageway out of the market. Firms produce homogeneous, indistinguishable, units of yield that are not marked. Each unit of data, for example, units of work, are likewise homogeneous. No single firm can impact the market value, or market conditions. The single firm is said

to be a value taker, taking its cost from the entire business.

of 32

There are expansive quantities of firms in the market. There is no requirement for government regulation, but to make markets more

competitive. There are thought to be no externalities, which are no outside expenses or profits. Firms can just make typical benefits over the long haul, yet they can make anomalous

benefits

Assumptions behind a Perfectly Competitive Market:1. Numerous suppliers each with an irrelevant offer of the market – this implies that each one firm is excessively little in respect to the general market to influence price by means of a change in it supply – every individual firm is thought to be a price taker

2. An indistinguishable yield delivered by each one firm – at the end of the day, the market supplies homogeneous or institutionalized items that are flawless substitutes for one another.

3. Shoppers have impeccable data about the prices all dealers in the market charge – so if a few firms choose to charge a price higher than the decision market price, there will be a huge substitution impact far from this firm

4. All firms (industry members and new participants) are expected to have equivalent access to assets (engineering, other variable inputs) and changes in generation advances attained by one firm can overflow to the various suppliers in the market

5. There are thought to be no hindrances to passage & passageway of firms in long run – which implies that the market is interested in rivalry from new suppliers – this influences the long run benefits made by each one firm in the business.

6. No externalities in generation and utilization so that there is no dissimilarity in the middle of private and social expenses

Short run price and output for the competitive industry and firm:In the short run the equilibrium market price is controlled by the collaboration between market demand and market supply. In the chart demonstrated above, price P1 is the market-clearing price and this price is then taken by each of the organizations. Since the market price is steady for every unit sold, the AR curve likewise turns into the Marginal Revenue curve (MR). A firm amplifies profits when minimal income = peripheral cost. In the outline over, the profit-maximizing output is Q1. The firm offers Q1 at price P1. The region shaded is the financial ( super normal profit) made in the short run in light of the fact that the decision market price P1 is more noteworthy than average total cost.

of 32

Not all organizations make super normal profits in the short run. Their profits rely on upon the position of their short run cost curves. A few firms may be encountering sub-normal profits in light of the fact that their average total costs surpass the current market price. Different firms may be making normal profits where total income equivalents total cost (i.e. they are at the earn back the original investment output). In the chart beneath, the firm demonstrated has high short run costs such that the decision market price is underneath the ATC curve. At the profit maximizing level of product, the firm is making a financial misfortune (or sub-normal profits)

of 32

The Effects of a change in Market Demand:In the diagram underneath there has been an increment in market demand (ceteris paribus). This causes an increment in market price and amount exchanged. The association's average income curve movements up to Ar2 (=mr2) and the profit maximizing output stretches to Q2. Perceive that the MC curve is the association's supply curve. Higher prices cause an extension along the supply curve. Taking after the increment in demand, total profits have expanded. An internal movement in market demand would have the inverse impact. Consider the impact of a change in market supply - maybe emerging from a cost-diminishing mechanical advancement accessible to all organizations in a focused market.

of 32

Benefits of perfectly competitive market structure: optimal portion of assets competition empowers effectiveness consumers charged a lower price responsive to purchaser wishes: Change in demand, heads additional supply They allot assets in the most effective way- both gainfully (P=mc) and allocatively

productive (P> MC) over the long haul. there is no data disappointment as all information is spread out equally only normal profits made simply take care of their chance expense maximum buyer surplus and monetary welfare Because there is impeccable learning, there is no data disappointment and information is

imparted equitably between all members. There are no hindrances to entrance, so existing firms can't infer any syndication power. Only normal profits made, so makers simply take care of their chance expense. There is no compelling reason to use cash on promoting, in light of the fact that there is

impeccable learning and firms can offer whatever they can deliver. What's more, offering unbranded merchandise makes it hard to develop a successful publicizing crusade.

there is greatest conceivable: consumer surplus economic welfare there is greatest allocatively and beneficial effectiveness: Equilibrium will happen where P = MC, thus designate effectiveness. In the long run equilibrium will happen at output where MC = ATC, which is profitable

effectiveness. there is likewise most ex

4.1 Profit maximizing or loss minimizing rule in the context of perfectly competitive market:

Perfect Competition, Loss Minimization or Profit Maximization: A perfectly competitive firm is ventured to create the amount of yield that minimizes monetary losses, if price is more noteworthy than average variable cost however short of what average aggregate cost. This is one of three short-run generation choices confronting a firm. The other two are profit maximization (if price surpasses average aggregate cost) and shutdown (if price is short of what average variable cost).

of 32

A perfectly competitive firm guided by the quest for profit is slanted to create the amount of yield that likens marginal revenue and marginal in the short run, regardless of the fact that it is acquiring a monetary loss. The way to this loss minimization creation choice is a correlation of the loss brought about from creating with the loss acquired from not delivering. On the off chance that price surpasses average variable cost, then the firm brings about a more diminutive loss by delivering than by not creating.

One of Three Alternatives:

Loss minimization is one of three creation choices confronting a perfectly competitive firm. Each of the three are shown in the table to the right. The other two are profit and shutdown.

With profit maximization, price surpasses average aggregate cost at the amount that likens marginal revenue and marginal cost. For this situation, the firm creates a monetary profit.

With shutdown, price is short of what average variable cost at the amount that compares marginal revenue and marginal cost. For this situation, the firm brings about a littler loss by creating no yield and acquiring a loss equivalent to aggregate altered cost.

Profit Maximization Rule:Profit is maximized where

Profit maximization standard: Produce until the point where the change in revenue from creating 1 more unit equivalents the change in cost from delivering 1 more units.

Assume MR > MC. In the event that I deliver 1 more unit, my revenues increment by more than my costs. Hence, if MR > MC, creating increasingly will build my profit. On the off chance that I can expand my profit by changing the extent to which I create, then when creating where MR > MC can't be profit-amplifying.

Assume MR < MC. In the event that I deliver 1 less unit, my revenues diminish by short of what my costs diminish. Consequently, if MR < MC, I can build profit by diminishing yield. On the off chance that I can expand profit when MR < MC, then picking q such that MR < MC cannot be profit-maximized.

In this way, to boost maximized, I must pick an amount q such that MR = MC.

MR = MC is a harmony as in it is the main spot where there is no motivation to change the creation level.

This control, the profit maximization guideline, is simply an application of the marginal rule (MB = MC).

Why? This MB of delivering an additional unit is the additional revenue you get. MR is the MB. So the 2 announcements are proportionate. The marginal rule is more general, and the profit maximization standard is particular to the firm creation choice.

4.2 Profit maximizing or loss minimization rule in the context of economic profit, normal profit, and economic loss:Profit maximization occurs in the context of perfectly competitive market where the marginal revenue equals the marginal cost. A company marginal cost suppose 10000 dollar and the marginal revenue suppose also 10000 then the profit maximization can occur. The profit maximization creates the economic profit or the super normal profit, normal profit and the economic loss in the context of perfectly competitive market as well as the monopolistic market situation. The economic profit, normal profit and the economic loss are discussed in the following section in the context of perfectly competitive market situation.

Normal profit:The normal profit under the profit maximization in the context of perfectly completive market occurs when the profit of an organization equals to the average cost. The condition of normal profit can be given in the following formula.

Profit (P) = Average Cost (AC)

In the long period, economic profit can't be managed. The landing of new firms or development of existing firms (if comes back to scale are steady) in the business sector causes the (flat) demand curve of every individual firm to movement descending, cutting down in the meantime the price, the normal revenue and marginal revenue curve. The last result is that, over the long haul, the firm will make just ordinary profit (zero economic profit).

Here P0 is the market setting price. At OP0 price total output OY0. So total revenue = OP0 *OY0= OP0C0 OY0

Average cost of producing per unit output is OP0. So total cost = OP0 * OY0 = OP0C0 OY0

Profit (R) = Total revenue – Total Cost

= OP0C0 OY0 - OP0C0 OY0

This is the normal profit under the profit maximization in the context of perfectly competitive market situation.

Economic Profit:The Economic profit under the profit maximization in the context of perfectly completive market occurs when the profit of an organization greater than the average cost. The condition of normal profit can be given in the following formula.

Profit (P)>Average Cost (AC)

Super normal profit is characterized as additional profit over that level of normal profit. Super normal profit happens where AR>ATC. Super normal profit is otherwise called abnormal profit. Abnormal profit implies there is an impetus for different firms to enter the business (in the event that they can)

Here OP0 is the market setting price and OP’ is the average cost of producing per unit output.

Total profit= Total revenue – Total cost

In this figure P0> AC so firm or industry make economic profit.

Economic loss:The Economic loss under the profit maximization in the context of perfectly completive market occurs when the profit of an organization less than the average cost. The condition of normal profit can be given in the following formula.

Profit (P) <Average Cost (AC)

On the off chance that organizations in an industry are encountering economic losses, some will clear out. The supply curve moves to the left, expanding price and decreasing losses. Firms keep on leaing until the remaining firms are no longer enduring losses—until economic profits are zero.

Before inspecting the instrument through which entrance and passageway take out economic profits and losses, we should inspect a vital key to comprehension it: the contrast between the bookkeeping and economic ideas of profit and misfortune.

Here market price is OP0 less than average cost OP0’ of produced output. Total revenue OP0C0Y0

and total cost is OP0’C0

’Y0. So the economy loss is P0P0’C0

’C0.

When the market structure is monopoly then shut down may occurred in the time of economic loss but in the perfect competitive shutdown create loss in short run but no loss in long run.

Conclusion:The market structure of a country of any industry changes over time. In the initial level of an industry, there are only few firms to dominate the firm and get more advantage and set price in their own way. Because they know that there is no possible alternative of them. In the south African telecom sectors the MTN or Vodacom initially set their price in their own way to make more profit from the competitors. But when some others firms like Virgin enter into the market become the market more competitive than before to set competitive prices.
