We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical separation can be both strategic complements and strategic substitutes. As a result, the equilibrium number of vertically integrated firms depends on the cost structure. When the local downstream monopolists merge, vertical separation tends to appear in equilibrium. When an upstream firm can price discriminate, the downstream firms vertically separate. When the downstream firms compete with each other, vertical integration tends to appear if the degree of product differentiation is lower. -- vertical integration ; vertical separation ; local monopolists ; inputs ; technology
This book investigates under which circumstances vertical unbundling can lead to a more efficient market result. The assessment is based on an interdisciplinary approach combining law and economics. Drawing on the assessment, circumstances are subsequently presented under which unbundling might become necessary. Additionally, less severe means of regulatory intervention are suggested in order to protect competition. Given its scope, the book is chiefly intended for scholars and practitioners in the field of economic policy and regulation law; in addition, it will give interested members of the public a unique opportunity to learn about the underlying rationales of regulation law and regulation economics.
The paper redefines different types of vertical market structure, such as double monopoly, bilateral monopoly, and two-sided monopoly. The core issue can be stated as follows: When there is bilateral monopoly, what are the differences between two-sided monopoly and one-sided monopoly as far as welfare consequences of retailers' rising buyer power are concerned. The results show that in tow-sided monopoly situation, from consumer welfare perspective, the results of vertical integration are better than the results of vertical separation, whereas in one-sided monopoly situation, the results of vertical separation are better than the results of vertical integration, so the vertical market structure of one-sided monopoly or one-sided competition effectively overcomes double marginalization problem, to counter the forces at this time the buyer countervailing power hypothesis is somewhat reasonable. Taking Inter-period factor into account, this conclusion is even more credible.
The most important book on antitrust ever written. It shows how antitrust suits adversely affect the consumer by encouraging a costly form of protection for inefficient and uncompetitive small businesses.
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.
We analyze the competitive effects of backward vertical integration when firms exert market power upstream and compete à la Cournot downstream. Contrasting with previous literature, a small degree of vertical integration is always procompetitive because efficiency gains dominate foreclosure effects, and vertical integration even to full foreclosure can be procompetitive. Surprisingly, vertical integration is more likely to be procompetitive if the industry is otherwise more concentrated. Extensions analyze incentives to integrate and differentiated Bertrand competition downstream. Our analysis suggests that antitrust authorities should be wary of vertical integration when the integrating firm faces many competitors and should be permissive otherwise.
This book analyses the vertical relationships of firms in an international context. These relationships, Khalid Sekkat argues, have gained further relevance due to the notable increase in vertical specialization of production across borders in the past few years.
The past two decades have seen a gradual but noticeable change in the economic organization of innovative activity. Most firms used to integrate research and development with activities such as production, marketing, and distribution. Today firms are forming joint ventures, research and development alliances, licensing deals, and a variety of other outsourcing arrangements with universities, technology-based start-ups, and other established firms. In many industries, a division of innovative labor is emerging, with a substantial increase in the licensing of existing and prospective technologies. In short, technology and knowledge are becoming definable and tradable commodities. Although researchers have made significant advances in understanding the determinants and consequences of innovation, until recently they have paid little attention to how innovation functions as an economic process. This book examines the nature and workings of markets for intermediate technological inputs. It looks first at how industry structure, the nature of knowledge, and intellectual property rights facilitate the development of technology markets. It then examines the impacts of these markets on firm boundaries, the division of labor within the economy, industry structure, and economic growth. Finally, it examines the implications of this framework for public policy and corporate strategy. Combining theoretical perspectives from economics and management with empirical analysis, the book also draws on historical evidence and case studies to flesh out its research results.
