This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores frequency and pricing decisions in a horizontally and vertically differentiated duopoly when there is competition between means of transport and where one of the firms need not necessarily maximize profits. The private and the mixed duopoly are compared and distortions from the social optimum are identified, both analytically and numerically. A mixed duopoly does not recover the socially optimal solution. However, the presence of a (public) non-profit maximizing operator is a useful measure to get closer to the social optimum. When both operators are (private) profit maximizers, some control measures such as price caps and minimum service availability would reduce the distortions from the social optimum.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a new dynamic model of Cournot-Nash oligopolistic competition that includes production and transportation costs, product differentiation, and quality levels in a network framework. The production costs capture the total quality cost, which, in turn, can also represent the R&D cost. We first present the equilibrium version and derive alternative variational inequality formulations. We then construct the projected dynamical systems model, which provides a continuous-time evolution of the firms' product shipments and product quality levels, and whose set of stationary points coincides with the set of solutions to the variational inequality problem. We establish stability analysis results using a monotonicity approach and construct a discrete-time version of the continuous-time adjustment process, which yields an algorithm, with closed form expressions at each iteration. The algorithm is then utilized to compute solutions to several numerical examples. The framework can serve as the foundation for the modeling and analysis of competition among firms in industries ranging from food to pharmaceuticals to durable goods and high tech products, as well as Internet services, where quality and product differentiation are seminal.

Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the core concept of the theory of mixed oligopoly and presents recent results that have arisen in a mixed oligopolistic market. The wave of privatization since the 1980s has taken the development of the theory of mixed oligopoly in several directions. Although the main concern of the theory of mixed oligopoly focuses on the effect of regime change—especially privatization of a public firm—on social welfare, existing studies have not considered the difference in economic environments. With drastic changes in economic environments along with economic development in recent years, the domestic and foreign markets have become more and more integrated, firms have become concerned about corporate social responsibility, and governments or politicians have had various interests and preferences. Against that background, this book revisits the question of how privatization affects social welfare by incorporating regional and international interdependency and investigates how firms’ activities for corporate social responsibility, governments’ preferences, and political economic situations affect the market circumstance in a mixed oligopoly. The dynamic aspect of privatization is also investigated.

Book excerpt: This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system (GHL) that can be estimated for the universe of public corporations in the USA, using publicly-available data. Using the model, I compute firm-level markups and decompose them into: 1) a new measure of firm productivity that accounts for product quality; 2) a metric of network centrality, which captures the extent of competition from substitute products. I estimate that, in 2019, public corporations produced consumer surplus in excess of 10 US$ trillions (against $3 trillions of profits). Oligopoly lowers total surplus by 11.5% and depresses consumer surplus by 31%. My analysis also suggests that both numbers were significantly lower in the mid-90s (7.9% and 21.5%, respectively). These results should be interpreted with care due to data limitations.

Download or read book Strategic Aspects of Oligopolistic Vertical Integration written by C. Wu and published by Elsevier. This book was released on 2017-12-28 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this text some fundamental issues concerning the strategic impact of vertical structures of firms are discussed in a successive oligopoly model. Vertical integration strategy has been identified as one of the key strategies which determine the success or failure of enterprises. Many studies on vertical integration are based on business experiences and interviews with managers. However, the extensive application of game theory in business economics allows this study on vertical integration to be based on sound theoretic ground. Moreover, the significance of public enterprises in some Western European economies and the trends of economic transition in Eastern Europe justify the efforts to analyse vertical integration issues in the mixed market, which is created by the participation of a public firm into an industry otherwise characterised as a successive oligopoly.

Available in PDF, EPUB and Kindle. Book excerpt: The theory of price and quality decision-making in industries with a few firms which recognize their mutual interdependence is of increasing interest to economists and policy makers. This book introduces a novel theory of that decision-making, based upon the notion of the industry as a community of agents who are involved in both competitive and cooperative relationships. It develops theories and illustrates methodological approaches to the analysis of price and quality decision-making in such instances of a 'rivalrous consonance of interests' among firms.

Download or read book Mixed Duopoly Product Differentiation and Competition written by Minoru Kitahara and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine the relationship between the equilibrium price and the degree of product differentiation in a mixed duopoly in which a welfare-maximizing public enterprise competes against a profit-maximizing private firm. Existing works on private economy show that increased product differentiation mitigates price competition. We find that, in a mixed economy, increased product differentiation can accelerate competition when the demand is elastic. The private firm chooses to locate itself too close to the public firm (and thus makes the resulting degree of product differentiation too low) for social welfare, which never appears in the private economy.

Available in PDF, EPUB and Kindle. Book excerpt: This research investigates three issues related to the economic performance of oligopolistic markets where firms produce differentiated products and compete in prices. First of all, this dissertation uses a Markov Perfect Equilibrium approach with fixed periods of commitment of actions to answer the question of what prices a duopolists will charge in equilibrium if they produce horizontally differentiated products, move alternatingly, and compete in prices forever. It is found that firms charge prices which are higher than Nash equilibrium prices but lower than the fully collusive equilibrium prices. Also, contrasted with the Nash equilibrium of the one-shot constituent game, the firm having the significantly higher demand responsiveness to its own price always charges a lower price than the other firm does although it has higher marginal cost. The dissertation then proceeds to study whether a firm can overcome its cost disadvantage by upgrading its product over the rival's, and if so, whether there exists a profit-division which will induce the low cost firm and the high cost firm to collude and no one has an incentive to cheat. The results show that (1) the ability of upgrading the product over the rival's can allow a high cost firm to earn higher profit than a cost advantaged low cost firm; (2) there exists at least one profit-division which can sustain full collusion; and (3) in the collusive equilibrium firms enlarge their quality differences to alleviate the price tension between their products. Finally, this work investigates the welfare effect of mergers which occur in an oligopolistic industry where firms produce differentiated products. It is shown that for the merger to be socially beneficial, the number of the merging firms must be less than the total number of firms in the industry minus the ratio of the products' own elasticity to cross elasticity. The analysis indicates that the welfare effect of a merger of a specific size depends on the substitutability among products of the industry.

Download or read book Strategic Complementarities and Endogenous Heterogeneity in Oligopolistic Markets written by Malgorzata Knauff and published by Presses univ. de Louvain. This book was released on 2006 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis consists of five chapters. The first of them contains introduction. Chapter 2 considers a broad class of two player symmetric games, which display a fundamental non-concavity when actions of both players are about to be the same. This implies that no symmetric equilibrium is possible. We distinguish different properties of the payoff functions, like strategic substitutes, complements and quasi-concavity, which are not necessarily imposed globally on the joint action space. A number of applications from industrial organization and applied microeconomics literature are provided. In Chapter 3 we generalize to the extent possible the known results for the case of games with one-dimensional action sets to the general case of games with action spaces that are complete lattices. We find that in the general case the scope for asymmetric equilibrium behavior is definitely broader than in the one-dimensional case, though still quite limited. Moreover, we investigate under which sufficient conditions asymmetric pure strategy Nash equilibria are always Pareto dominated by symmetric pure strategy Nash equilibria. In Chapter 4 we deal with the effects of market transparency on prices in the Bertrand duopoly model. We consider two types of strategic interaction between firms in an industry - strategic complementarities and substitutabilities. In the first case, the results are close to conventional wisdom, especially, when in the same time products are substitutes. Namely, equilibrium prices and profits are always decreasing in transparency level, while the consumer’s surplus is increasing. Considering price competition with strategic substitutes, an ambiguity in the direction of change of prices appears. This leads to ambiguity concerning equilibrium profits and surplus changes caused by increasing transparency. In Chapter 5 we provide general conditions for Cournot oligopoly with product differentiation to have monotonic reaction correspondences. We give a proof for the conditions stated by Vives (1999). Moreover we elaborate more general requirements. They allow for identifying increasing best responses even in case inverse demand is submodular, and similarly, decreasing best responses in case of supermodular inverse demand. Examples illustrating the scope of applicability of these results are provided.

Download or read book Price Competition in a Mixed Oligopoly Market written by Amarjyoti Mahanta and published by . This book was released on 2016 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several studies on mixed oligopoly indicate that the ownership pattern of firms does not affect the equilibrium price. This idea often suggests that ownership is irrelevant. In a mixed duopoly under price competition, firm ownership is irrelevant. This study reveals that ownership is irrelevant in a single publicly owned firm and in any positive number of privately owned firms. However, if two or more publicly owned firms exist, then ownership becomes relevant in a homogeneous good market with a strictly increasing convex cost schedule and a downward sloping demand curve. If firms set the price sequentially and if the lone public firm is a price leader, then social welfare is constantly greater than when the latter is a price follower. The unique price is the competitive price when the public firm moves first in the sequential game.

This book was released on 2013-03-14 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book a rigorous, systematic, mathematical analysis is presented for oligopoly with multi-product firms in static as well as dynamic frameworks in the light of recent developments in theories of games, oligopoly and industrial organization. The general results derived in this book on oligopoly with multi-product firms contain, as special cases, all previous results on oligopoly with single product as well as oligopoly with product differentiation and single product firms. A constructive nu- merical method is given for finding the Cournot-Nash equilibrium, which may be extremely valuable to those who are interested in numerical analysis of the effects of various industrial policies. A sequential adjustment process is also formulated for finding the equilibrium. Dynamic adjustment processes have two versions, one with a discrete time scale and the other with a continuous time scale. The stability of the equilibrium is thoroughly investigated utilizing powerful mathematical results from the stability and linear algebra literature. The methodology developed for analyzing stability proves to be useful for dynamic analysis of economic models.

Book excerpt: Advanced Textbooks in Economics, Volume 23: Public Enterprise Economics: Theory and Application focuses on economics, mathematical economics, and econometrics, including microeconomics, marginal-cost pricing, taxes, and income effects. The manuscript takes a look at the essential parts of public sector pricing models, normative optimum theory, and normative piecemeal theory. Discussions focus on welfare improvements with non-tight constraints, welfare -improving increases of public inefficiency, conditions for optimal prices and quantities, compensating for income effects, and conditions for optimal quality. The book then ponders on marginal-cost pricing, Ramsey pricing, rate of return regulation, and pricing with distributional aims. Topics include comparing distributional and allocative pricing, prices versus taxes, optimum Ramsey policy, influence of Ramsey prices on allocation, distribution, and stabilization, and consequences for allocation, distribution, and stabilization. The publication examines bus and underground services in London, economic theory and empirical analysis, and different approaches towards optimal quality, including empirical studies on bus and underground demand, organizational and political history, and microeconomics of the representative consumer. The book is a valuable source of data for researchers interested in public enterprise economics.

Download or read book Public Monopoly Mixed Oligopoly and Productive Efficiency written by Akira Nishimura and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, the introduction of competition into the public sector seems to lead to higher cost-efficiency in service production. However, there are examples of substantial cost increases in some areas. In this paper, using a mixed oligopoly model, we investigate the effects of deregulation on the cost-reducing incentives of a public firm. Our results show that a firm that is a public monopoly has greater incentive to conduct cost-reducing investment than a public firm within mixed oligopoly market.
