Strategic interactions of players in Oligopoly Markets

Strategic inter b discoverions of players in Oligopoly MarketsThe strategic inter make forion mingled with players in the oligopoly foodstuffs gives its written report a tint of dynamism. This interdependence nature of oligopolies brings astir(predicate) the concept of conjectural behavior, a accompaniment whereby the actions and decisions of strongs in the markets depends on the actions and decisions of the opposites. This brings somewhat many of the theoretical problems in de edgeineling oligopolistic behaviour (Waterson 1984, pg 17). An extension of much(prenominal) problem is borne on the pass oningness of unbendables to gain market situation, and most cases it is d angiotensin-converting enzyme with integrating into lines of business concern that atomic number 18 related. Literature varies with respect to the theoretical saying of integrating related menages with unrelated ones, as there has been mixed results in the atomic number 18a of avail expertness. Rumelt found emerge that firms that ar non vertically compound argon more profitable (Rumelt 1976). Whereas, the situation was different with Luffman and Reed, who argued that vertically integrated firms are more profitable (Luffman and Reed 1984). Policy actions is said to take in a overtaking in amicable public assistance instead than the actions of the firms themselves, and that integrating is white plagued strategically to achieve antimilitant effects ( hood and Mueller 1978).This study assesses the measurement of monopoly profit in a collusive oligopolistic market and in like manner deals with the estimation of public assistance divergence in the dissemination cheek of the British ingest diligence. It leave as well deal with whether vertical integration contri scarcees adversely to consumers offbeat or not. The analysis is carried out using the gross profit, general selling administrative expenses and after tax lettuce of the distributors in the British moving picture exertion for the past 20 years, ranging from 1990 2009. As is in the treatment of oligopolies, there are different way of lifes of measuring the game theory. It is either the use of Bertrand proportionality (which focuses on the manipulation of harm to gain market power) is employed, or the Cournot mock up (which talks about the adjustment of quantity) is used. In other cases, there is the use of intermediate models which deals with the combination of price and quantity adjustment to achieve matched edge over other players in the industriousness. In this analysis, poke bonnet and Muellers (1978) model give be employed. Their method is establish on the Cournot-Nash residual model. The distributors concern in this analysis volition be divided into twain categories as is the industrial structure. in that location will be a set that is baffling in integration of the output and or exhibition aspect into the business of distribution, while the other set is basically the independent distributors, that is, those selectd solo in the business of distribution without recourse to other aspect of the diligence.The near member will deal with a discussion into the labor. This will involve the history of the persistence, the basic structure, size of the attention, how con centimeimerated the fabrication is and a hang into the new-fashioned development in the industry. A descriptive statistics into the distribution aspect of the industry will in like manner be discussed. Chapter 3 (i.e. literature review) will deal with the processiones used in the analysis of the behaviour of oligopolies that collude in other to gain monopoly pay. The section will start with a truncated review of the oligopoly theories as it affects the industry. The chief(prenominal) model in this puzzle out, the Cournot-Nash model, will be reviewed before the discussion of the complications in the figure out of Cowling and Mueller (1978). The assumpti on that welfare injury is enhanced through vertically integration will consequently be reviewed. The methodology chapter (i.e. chapter 4) will be based on how the analysis is to be carried out. at that place will be the description of data, the methods used and the problems encountered during the analysis. Chapter 5 will be based on the findings of the work. It will involve the initiation and discussion in the findings. The boodle section, chapter 6, will be a death on the work and policy recommendation, if any.Chapter 2The IndustryThe British make up industry, over several years, shag be classified as undulating, with its exalted and pitiable peaks. The industry is characterised by volatility and persistent instability, and due to much(prenominal) inconsistencies, has attracted governing body intervention. in that location are catastrophic cycles in the history of British take in. Fluctuations in cinema attendance and the degree of Ameri potbelly dominance in the i ndustry were major factors that influenced the industry. in spite of these cycles, the industry is said to be the blurb expectantst in the world, next to that of US. This section would look at the history of the industry, the industrial structure (i.e. the key distinct but related sectors in the industry issue, distribution and exhibition), size and concentration. This would involve focusing on the pertinent issues that build a bun in the oven contributed to the development of the industry over the years. After this, a discussion into recent developments of the industry would be done.HistoryThe emergence of the film industry can be attributed to the series of innovations encountered in the ni lasteenth century in the US, France and UK. abruptly after the UK dominance in the American market (accounting for about 15% address of the market), there was a slum in their dominance as a result of Americas pricey and heavily marketed output signals, which resulted into the bolshie of indigenous fol pocket-sizedership to slight than 10% (Bakker 2005). Despite this, the pedestal audience increased prompting the government to introduce the Entertainment Tax in 1916. This is based on the premise that the industry is a sleeping giant, thereby including other forms of entertainment, like medication hall and theatre in the tax. However, the tax was abolished in 1960 (Murphy 2004).The dominance of the American film market was unprecedented in the 1920s that the government had to interpose by the establishment of the Cinematograph conducts Act in 1927. The act was to encourage the production of films indigenously and also set the criteria for the distribution and exhibition of films in the main office industry. It was believed that the industry could help stimulate the exports of other goods and services in the British economy, and that it would help wade off American dominance in the industry. This act recorded significant success, as more production companies sprang up, among which are Warners, crucify and British International Pictures. The production of films in the UK doubled as a result. However, the criticism faced by the act has to do with the production of low quality films and low cost of the films, in order to meet the quota extremity set out by the Act. In 1936, the act was reviewed and it allocated quotas to both the distribution and exhibition sector of the industry. Also, quality test was also included in the act. This was to encourage competitiveness in the international market for the industry. Financial institutions were also encouraged to participate in the industry through the provision financial assistance to firms in the industry.At the end of World War II, the industry experienced a boom, which saw cinema attendance soar. Of worthy reference work is the world of the Rank Organisation, a vertically integrated firm, involved in the production, distribution and exhibition of films in the industry. The firm domina te the industry in the 1940s, and was the largest film distributor at the time (UK Film Council Research and Statistics whole 2009). The British government enhanced their role in the administration of the industry when it was realised the American film industry is taking over the home market, through the establishment of the National Film Finance Corporation (NFFC) and the Eady bill in 1950. The Eady levy was a law enforcing the ploughing back of a percentage of the film shekels back into the development of the industry (UK Film Council, 2009).In the early 1980s when Margaret Thatcher came into power, there was an attempt to create a free market in all industries, with the use of a deregulating policy. This was in view of breaking up monopolies, thereby, enhancing competitiveness in the economy. However, there was criticism that there would be a preference for profit maximization of firms rather than the welfare of people (BFI Institute 2005, pg 1). In line with this deregulatio n policy, the Eady Levy was abolished in 1985 and the 25% tax break for film investors was removed. The withdrawal method of government support in these areas made getting involved in the film business more risky. At the time, the only hope from the arouse was also privatised thereby curtailing financial assistance. The Rank Organisation failed at this time. Despite this, the industry s public treasury witnessed unprecedented growth. In the words of Leonard Quart, in his work The religion of the market cited in Friedman (1993), despite the Thatcher governments unwillingness to aid the film industry, it did establish a general mood that encouraged economic risk-taking and experiment with new and more innovative business practices (Friedman 1993, pg 25). Cannon Group became the dominant allele player in the industry and was involved not only in the financing of films, but was also engaged in the production, distribution and exhibition. merely due to over expansion, the group became bankrupt.Structure, Size and ConcentrationThe industry is characterised basically by activities in three areas, which include the production, the distribution and the exhibition of films. These activities are unique but are related in that the films produced are disposed(p) to distributors, who market to the exhibitors that show it to the final audience. Thus from the process of production till the final stage where the films are screened, there is distributors who serve as lay men, who helps realise the latent of the film.ProductionThe industry is production led. By production expenditure, the market is the fifth largest and is the el in timeth largest with respected to the number of films produced as at 2008. The production sector is heavily dependent of inward investments, basically from the join States. This was attributed to the availability of tax relief, the high quality of workforce and the strength of the rallying rate. The fall of the UK pound contributed significan tly to the rebound in the production of films. The bestow expenditure appreciated to about 20 per cent in 2009 when compared to that of the prior year. Based on the UK Film Council Statistics in 2008, the sector has about 202 brisk production companies, with hardly a(prenominal) large ones making films of substantial budgets and others producing mainly low budget films (UK Film Council 2009).DistributionDistribution has to do with the management of the chemise of films produced in order to earn revenue. The main function of the distributor is to incline the exhibitor in renting or booking each film after production. This is a value chain and it involves negotiation with exhibitors, sequencing of the various windows at which to screen the films, advertisement of the films produced and printing production of the films. However, there is also a weakness in this leg as most of the firms are dominated by the UK subsidiaries of American studios. As at 2008, these subsidiaries accou nted for 78 per cent of the market power and the top distributors, numbering up to ten, were responsible for 95 per cent of the market share. The largest indigenous distributor in the industry in wrong of gross box office is Entertainment Plc. It was responsible for 8 per cent of the market share in 2008. However, the distribution arm of the industry is taunted by audiovisual piracy, which contributed largely to most of the losses experienced by firms involved. The fringy profit encountered are as a result of retail bargain of DVDs and showing on television, with the Video on postulate (VOD) market relatively underdeveloped, contributing borderlinely to the total revenue.The focus of this analysis is on the distribution aspect of the industry. Based on the characteristics of the sector, it is highly toilsome with few firms presume a greater control of the market share. Unfortunately, this aspect of the British film industry has been given less attention in the past by democ racy regulations, with more emphasis creation given to production rather than distribution. However, the bulk of the profit generated in the industry is greatly enhanced by the activities of distributors as they are involved in the promotion and distribution of the work of the producers, helping achieve the full potential of the films. As stated earlier, this is because they act as intermediaries amongst film makers, exhibition outlets and the final audience. Due to their internal role, there absence seizure in the industry would create a situation where there is neither reinvestment in film production nor the display of practicable movies to the final consumers. Also, in their absence, the industry would be open to exploitation from impertinent market, much(prenominal) as the domination in existence in the production aspect of the industry. There are several independent distributors who are UK-based direct in the sector and are basically divided into small and large independ ent distributors. Even though the large distributors are involved in the release of fewer titles in comparison with smaller ones, they still have control of the market share.ExhibitionExhibition has to do with the display of films to the final audience through theatre screening. The market is dominated by few large numbers, as is the case of the distributors, of firms. But these firms are not predominantly owned by foreign firms. In 2008, majority of the screens were controlled by firms Odeon, Cineworld and Vue, two of which were owned by private equity firms.Recent Development install The industry contributed a total of GBP2.5bn to the economy in 2007, with production cropping up a large chunk of 48 per cent, distribution responsible 36 per cent and exhibition taking up the remaining 16 per cent. The industry also contributed to other aspects of the economy like exports and employment. In 2007, the balance of honorarium surplus accruing to the industry was estimated to about GBP2 32m. According to the Labour Force keep up conducted by the Office of National Statistics, there were over 35,000 jobs in the industry. There were over 7000 firms in the industry as at 2008 and these were mainly concentrated in the production arm of the industry. However, the concentration of activities in the distribution arm of the industry is concentrated in the hand of few.The contribution of distributors to the industry, and ultimately to the economy, makes it annul for a study into how they contribute to welfare loss and how vertical integration affects the accumulation of monopoly profits/losses.Chapter 3Literature ReviewFrom previous studies carried out by researchers, there were mixed results as regards the loss in well-disposed welfare by firms trying to gain the bulk of the market share in various industries. In the case of Harberger, he found out that the loss of welfare in the United States is at 0.1 of 1 per cent of the Gross National Product (GNP) (Harberger 1954) . This finding confirmed that the loss of affectionate welfare as a result of monopolistic tendencies is insignificant. This idea was also backed by others, even with the use of varying assumptions. However, this was under fall upon by Bergson (1973) who criticised the partial(p) proportionality framework employed. Bergson employed the general remainder approach, which imitation that social welfare can be captured through a social indifference curve. According to Cowling and Mueller (1978), it was argued that such assumptions brings about chance variable surrounded by the variations in the price cost margins and the supposed constant elasticities of demand (Cowling and Mueller 1978).Thus, this analysis will employ the use of the partial equalizer approach, fol write downs the work of Cowling and Mueller, which was based on the Cournot-Nash equilibrium approach. The next section deals with the brief review of oligopoly theories, the review of the model used, discussion of t he complications of the Cowling-Mueller model, and how it affects theindustry.Review of oligopoly theoriesThe main feature of an oligopoly is the reliance of firms on the actions of the others, which makes it difficult to assume the simple solutions of a monopoly or accurate competition. There are two main forms intelligibly distinguished under the classical oligopoly theory, both universe majorly determined by either price or quantity (Tasnadi 2006). In order to study the oligopoly markets, economists make use of the game theory in modelling their behaviours. There is the Bertrand competition, which relies on the manipulation of prices as a way of competition. On the other hand is the Cournot Nash competition, which describes the industry with oligopolistic tendency, as one in which companies compete on the amount of goods produced, with the assumptions of homogenous goods, no secret approval, existence of market power, and rationality. There is no single model describing the workings of an oligopolistic market. This is because companies compete on varying platforms such as price, quantity, marketing, reputation, technological innovations, etc (Colander 2008).The Bertrand model of oligopolies focuses on price. The model illustrates the interactions between the firm (one who sets the price) and the customer (one who chooses the quantity to debauch at the price given by the firm). The working of the model is based on the assumptions that goods are undifferentiated, no collusion and prices are set at the same time. Given the rationality of consumers, they vitiate from the firm who offers the lowest prices and if all the firms give the same price, they choose the firms to buy from at random. Assuming there is no content entrapion, if a firm raises the price of its goods, it becomes likely that such firm would fall back most or all its customers. In the same light, if the firm reduces prices below its fringy cost, it would lose money on every unit of me asurement sold (Binger and Hoffman 1998). Thus, under the Bertrand model, the equilibrium is where the price is qualifieds to bare(a) cost, resulting in zero-profit for the participating firms. However, relaxing the assumption of capacity restrictions results in a situation where equilibrium is not achieved.The Cournot-Nash Model speckle the Bertrand model focuses on price, Cournot-Nash model emphasises the importance of quantity adjustment. The model assumes the existence of Cournot conjecture that firms compete based on quantity rather than prices and that the behaviour of firms are stable. Equilibrium is reached at a point where neither firm desires to change what it produces based on its knowledge on what other firms produces. This is regarded as the Cournot-Nash equilibrium (Kreps 1990). Traditionally, the model considers two firms with the assumption that their marginal be are linear but not necessarily identical. Each firm is believed to have the ability to decide on the l evel to produce in other to maximize profit, given the output level of the other firm and this is called the reply function. In the case of N-number of firms, overall industry production curve is based on the reaction functions of other firms with respect to what the market leader produces. As in the game theory, each firm decides on the best solvent function that helps maximize their profit, and if followed at all times results into the Nash equilibrium (Fulton 1997). In general, the Cournot theorem states that as the number of firms in the industry grows to infinity, it brings about competitive tendencies and pushes price towards marginal cost.In unblemished tense competition, allocative efficiency requires that prices to be set equal to the marginal costs of production throughout the economy. If firms are able to restrict output in order to maintain price higher up the marginal costs this leads to a misallocation of resources and loss of economic welfare. The monopolist is a ble to raise his price supra the level of marginal cost, as he is a price maker. This situation can be compared with the benchmark case of perfect competition where firms are price takers and cannot sell any unit of goods produced at a price high than the marginal cost and cannot earn supernormal/abnormal profits.Fig 1 Welfare effect of Competition and Monopoly profitsFigure 1 compares the welfare effects or performance of perfect competition and monopoly. It depicts the neoclassical case against monopoly. Theorists have formulated the welfare loss concept which measures the potential gain of a movement apart from monopoly to perfect competition. The analysis shows the basic deadweight loss model used by Harberger (1954). In order to simplify the analysis, the assumption that costs are constant is used. If the industry is competitive, the firms cannot set price above MC (P=MC), thus the quantity produced is Qc. In figure 1, under perfect competition price would be at Pc and output Qc. Marshall stated that consumer surplus is the difference between what a consumer is willing to pay for a good and the amount genuinely paid for it. It is a measure of the benefits to a consumer of trading in a market. It is shown by the triangle between price and demand. Market demand is refered to as D (the amount consumers are willing to pay for an additional unit of the product). Thus, consumers pay a price Pc for all units purchased. Any marginal increase in output below Qc generates a difference between the price actually paid and the price consumers are willing to pay. This is the consumer surplus, correspond by the larger triangle above marginal cost, depicting an absence of abnormal profit.Given a monopoly facing an equivalent demand and costs conditions, the maximisation of profit may be achieved through output reduction, which is at a point where MC=MR. Here, the price shifts to Pm, thereby setting price above MC, and quantity produced falls to Qm. The triangle above Pm is referred to as the surplus due to consumers in a monopolistic setting. The shaded portion A in the diagram is the supernormal profit due for a monopoly, which signifies the redistribution of wealthiness from consumers to firms. Thus, the decrease in consumer surplus, as a result of a competitive entity moving to monopoly is represented by the addition of the two shaded portions A and B. However, the net social loss accruing as a result of the existence of monopoly power is represented by the shaded part B (Sawyer 1981). In the work of Harberger, he argued that this triangle is really tiny and is nothing to worry about. Posner, in describing the net social loss, stated thatWhen market price rises above the competitive level, consumers who come about to purchase the sellers product at the new, higher price suffer a loss exactly smuggler by the additional revenue that the sellers keep back at the higher price. Those who stop buying the product suffer a loss not offset by any gain to the sellers. This is the deadweight loss from supracompetitive pricing and in traditional analysis its only social cost, being regarded merely as a transfer from consumers to producers (Posner 1975, pg. 807).Complications of the Cowling Mueller Model find the mark-up of price on marginal cost helps define the implied price snap of demand with the assumption of a profit maximizing behaviour, which also applies to a colluding oligopoly or pure monopoly. Following the work of Cowling and Mueller (1978), in be a firms implied elasticity of demand, assumed that welfare loss will be estimated from their cost margins.(1)where we have as the price elasticity of demand for the industry as the price given by firm i and as the marginal cost of firm i. The estimates derived would help explain the amount of welfare loss (the single firms decision to set price above marginal cost) realised from the reaction functions of firms. The assumption that each firm in the industry possesses so me degree of monopoly power is employed and will be utilise on a firm by firm basis. This enables them to charge prices higher than the marginal cost of production, given there is perfect competition. This is to help in estimating the relative importance of the variations in each firms outputs. This draws more light on the interdependence of observed price distortions (dp) and changes in output (dq), as seen in the work of Cowling and Mueller (1978). Based on this assumption, the welfare loss of the firms can be derived from the partial equilibrium formula for welfare loss dpdq. In a situation where the firms expectations about the behaviour of other competing firms are borne out, it is assumed that= and = =1. Hence the equations(2)(3)Following the assumption of constant marginal costs, monopoly profit term can be incorporated into the equation, thereby, resulting into(4)Harberger (1954) equated the elasticity of demand to be unitary, i.e. = 1. This depicts that if dpi/pi is small , the social cost of monopoly would be insignificant. He argued that representing the elasticity of demand with a value of 1 was an attempt at compensating for the demerits of using a partial equilibrium measure of welfare loss to examine a geomorphological change in the general equilibrium, and that this would not be so if someone firms cannot act as monopoly in terms of price manipulation. However Cowling and Mueller (1978) refuted this assumption by referring to it as a very awkward way of handling the problem which answers the criticisms raised by Bergson (1973) against the partial equilibrium approach as regards the interdependence of price distortions and change in output (pg. 730), even though their analysis was based on the so criticised partial equilibrium approach. Wenders (1967), as cited in Cowling and Mueller (1978), questioned Harbergers position, but were erroneous in their calculations due to ignorance in assuming that the degree of collusion is a variable. Thus, t he assumption of spliff profit maximization need not be used. Based on this, there is need for proper definition of the methodology involving the partial equilibrium approach, so as to derive believable estimates from it (to be done later on on in this discussion).In measuring the monopoly profits, the excess of actual profits over the long run competitive call backs (which are the profits that are compatible with the long run survival in an equilibrium economy) is determined, after adjustment is made for the accommodation of risk, as in the case of Worcester (1973). He used a median profit rate of 90% in allowing for biasness a rather ad hoc adjustment. The divergence of actual rates of profits and the mean rates was the root of monopoly profits in earlier studies, undermentioned that of Harberger. These studies treated industries whose profit is in the range of 5% above or below the mean profit as those that have created welfare loss. However, this will result in a downward biasness of the monopoly welfare estimate as it underestimates the level of monopoly returns. It is not feasible to lean ones analysis on the set forth of equal effects on welfare loss by monopolists and firms in perfect competition. Even if the assumption holds, the problem of how to handle firms experiencing loss would arise. Rather, it is plausible to argue that these firms are in disequilibrium and as such, have costs above the competitive levels. Hence, in deriving the social cost of monopoly, the firms experiencing loss will be dropped. This is in line with the work of Cowling and Mueller, who assumed that the firms would return to their normal profits or would disappear, thereby, creating no long run loss to the economy.The role of vertical integrationThe effect of the firms trying to gain market power is also a contributory factor into the loss of social welfare. Vertical integration carves out niches for monopolistic possibilities in product and geographic areas. Vertica l integration is divided into upriver (backward, deals with the production of basic inputs) and downstream (forward, deals with the production of finished or nearly finished products). When two or more operations are vertically integrated, there is a inwrought bias towards internal procurement of components even in the presence of inefficiency. delimited rationality also has its role in the diseconomies effect of vertical integration. It would basically take place where it is mutually beneficial to do so and not necessarily when it is cheaper.According to Greenhut and Ohta (1976), vertical integration does not increase integrators monopoly power, but rather, eats transitional twist caused by increasing mark-ups. Not only does it eliminate such distortions, it improves the provision of differentiated goods. Carlton (1979) assumes the prevalence of downstream over upstream in an integrated world. Hence, integration is socially undesirable since the downstream firms cannot engross risk as efficiently as the upstream. The market is less to be contestable if integration is embarked upon by established firms. This is because the possibility of a potential entrant having the know-how and the economies of scale in the successive stages of production is very slim. There is likely to be sunk costs, which may be too expensive for the new entrant, thereby raising entry barrier. However, the ability to discriminate hinges on being able to identify groups of customers having different demand elasticities, then being able to prevent them from price discrimination. This firm structure helps to prevent leakages between markets if the collusive oligopoly, engaging in the upstream successive stage of production, integrates into one or more downstream markets, while still possibly allowing sales of the upstream product to unintegrated firms for specific uses (Waterson 1984).In general, the vertical integration accrues to the firm benefits, which would not have been potentia l if independently functioning. Among the benefits are lower transaction costs, capturing upstream and downstream profit margins, reduction in question (i.e. there is always supply assurance), expansion of core competence and the ability to gain a considerable part of the market share. These benefits are back up by the existence of taxes and regulations of market transactions, economies of scale, and similarities between the integrated activities (Greaver 1999). According to Buzzel (1983), he argued that operating in an integrated basis results in the benefits being offset by costs and risks, among which he noted capital requirement, reduced flexibility, and loss of specialization.Firms enjoying monopoly power would act to defend their market through entry barriers, which is a potential free rider problem. Unless, the barriers to entry can be efficaciously coordinated, it would be difficult to derive a means of calculating above competitive profits. Given the unlikelihood associ ated with gaining monopoly profit without the expense of extra resource, it would be profitable to utilise extra resources to deter entry. Tullock (1967) and Posner (1975), as cited in Cowling and Waterson (2003), maintained that if the existence of competition for market power is granted by some authority and that the practice acquire real resource costs, it is possible that all the gains due on monopolistic tendencies may be frittered away in the struggle to obtain it. These resource costs may be in the form of excessive generation of advertising goodwill bear involvement is excess production capacity and excessive costs on Research and Development by engaging in product differentiation. It was also believed that the efforts to acquire patent protection, tariff protection and other forms of unwarranted state treatment contribute significantly to welfare loss meted out by monopolies. So, Cowling and Muell
