Book Description
'This is a high-quality book on an important and central topic in the theory of industrial organisation. It is a cohesive and extremely well written volume which is destined to become a standard work on the subject.' - Mark Casson, University of Reading, UK This original new book offers a comprehensive and engaging perspective on the theory of vertical differentiation. It enables the reader to grasp the key concepts and effects that product quality has both on firms' behaviour and market structure, and the ways in which this relationship has evolved. With contributions from prominent figures in the field, the book investigates a number of important topics, such as the choice of the optimal product range, profit sharing, the existence of equilibrium in duopoly games, positional effects attached to status goods, international trade, collusion, advertising and the dynamics of capital accumulation for quality improvement and product innovation. Using both static and dynamic approaches, these aspects are assessed in relation to the manifold issues of regulation, competition policy and trade policy. Product differentiation and its influence on consumer behaviour and the performance of firms is a core topic in the existing literature in the fields of industrial organization, international trade and economic growth. This book will be an essential read for researchers, students and professional scholars working in these areas, especially those with an interest in antitrust regulation.
The Economic Theory of Product Differentiation

Category : Business & Economics
Languages : en
Pages : 220
Book Description
There are few industries in modern market economies that do not manufacture differentiated products. This book provides a systematic explanation and analysis of the widespread prevalence of this important category of products. The authors concentrate on models in which product selection is endogenous. In the first four chapters they consider models that try to predict the level of product differentiation that would emerge in situations of market equilibrium. These market equilibria with differentiated products are characterised and then compared with social welfare optima. Particular attention is paid to the distinction between horizontal and vertical differentiation as well as to the related issues of product quality and durability. This book brings together the most important theoretical contributions to these topics in a succinct and coherent manner. One of its major strengths is the way in which it carefully sets out the basic intuition behind the formal results. It will be useful to advanced undergraduate and graduate students taking courses in industrial economics and microeconomic theory.
Issues in Operations Management and Marketing Interface Research

Book Description
This dissertation studies important issues in supply chain management and marketing interface research: competition, product line design, and channel efficiency, at the presence of vertically differentiated products. Vertical differentiation as a means of price discrimination has been well-studied in both economics and marketing literature. However, less attention has been paid on how vertical differentiation has been operationalized. In this dissertation, we focus our study on two types of vertical differentiation: the one created by a product line which is produced by the same firm, and the one created by products from different firms. We especially are interested in the so-called private label products vs. the national brand products. Specifically, this dissertation explores how vertical differentiation can affect the interactions among the members of a supply chain in several different contexts. In the first piece of work, we use a game theoretic model to explore how the ability of a retailer to introduce a private label product affects its interaction with a manufacturer of a national brand. In the second essay, we are investigating how an original equipment manufacturer (OEM) will be affected by the entry of a competitor when there are strategic suppliers of a critical component. If these suppliers behave strategically, it is not clear that the entry of other players will necessarily be harmful to the incumbent. In the last work, we pay our attention to an emerging change happening in the industry: some retailers begin to sell their private labels through their competitors. We investigate the strategic role of a retailer selling her own private label products through another retailer. In summary, this dissertation illustrates how vertical differentiation play a crucial role in firms' supply chain as well as marketing strategies. Therefore, it is important for firms to recognize these strategic issues related to vertically differentiated products while making operations/marketing decisions.
The Introduction of New Product Qualities by Incumbent Firms

Book Description
This study analyzes the optimal provision of goods in a market characterized by vertical product differentiation. We consider a duopoly model in which incumbents may introduce a new product with certain quality, and decide whether to keep or to withdraw the existing product from the market. We find that the strategic and cannibalization effects dominate, such that no room is left for discrimination among consumers. The innovator always withdraws the existing product from the market, in order to reduce price competition and to avoid cannibalizing its new product demand. In contrast to horizontally differentiated markets, firms are better off not to offer a range or interval of product qualities in vertically differentiated markets. Hence, firms fare better, despite offering a smaller variety of goods.
Modeling Vertical Markets of Differentiated Goods

Book Description
This is a collection of essays on the topic of vertical markets and resellers. The first two chapters look at the effects of mandatory dealer laws on prices and profits in vertical markets with differentiated goods. The third chapter looks at the quality of products chosen when manufacturers use resellers compared to when they do not. All three chapters show that competition is lessened when mandatory dealer laws exist. Chapter 1 addresses the US automobile market which has laws in almost every state that require sales of new vehicles go through franchised dealers, and manufacturers are not allowed to sell directly to consumers. While vertical markets can provide many benefits to both producer and consumer alike, double-marginalization is often seen as a problem for producers and consumers with vertical markets; whereby firms on different levels both have market power and thus are both able to charge a markup over cost. Contracts and implicit agreements can mitigate or lessen the negative externality associated with double-marginalization, but I develop a model to show that double-marginalization can be a good thing for producers, while simultaneously being bad for consumers. The model has a single dimension on product differentiation and different levels of vertical markets. In this model, firms either sell to consumers or other firms. How far removed the manufacturer of the good is from the final consumer determines the number of vertical markets. A market with one level consists of a manufacturer who sells directly to consumers, while a market with two levels consists of a manufacturer who sells to a reseller who in turn sells to consumers. I find that the profits of the manufacturer of the good can be up to three times as high when there are two levels instead of one and that they will always be at least twice as high. This model also shows that manufacturers can benefit from the existence of a law that requires they use dealers, even though any one single manufacturer has an incentive to not use a dealer. Chapter 2 addresses mandatory dealer laws in a setting without perfectly inelastic demand. Under a certain set of circumstances, manufacturers can earn higher profits after the introduction of these mandatory dealer laws than they would be without them. In this chapter, I remove the perfectly inelastic total demand restriction, and instead show how the elasticity of total demand plays a role in a manufacturer's preference for a mandatory dealer law. For the model used in this paper, I find that total demand does not need to be very inelastic at all, and in fact, can be elastic at the equilibrium prices and quantities. The findings in this paper run contrary to expectation, where double-marginalization is something that hurts manufacture's profits. In chapter 3, I analyze the benefit of moving first in a vertically differentiated market with manufacturers and retailers. Both retailers and manufactures are assumed to be profit-maximizing entities. Here the choice of the incumbent manufacturer creates an indifference between entering with a higher quality or entering with a lower quality for the entering manufacturer. Entry-quality decisions and wholesale pricing are related to the competition of retailers selling the manufacturers product and the degree of consumers' taste for quality. I examine the indifference of the entering manufacturer and highlight the benefits of being able to set quality first as an incumbent manufacturer when pricing stages are simultaneous. Stackelberg competition in the quality stage allows for the possibility for inferior-quality entry as well as superior-quality entry. The first-mover advantage dominates the high-quality advantage in this setting which is consistent with my findings in the dock and boat-lift markets.
Spatial Competition in a Differentiated Market with Asymmetric Costs

Book Description
Spatial quality choice is introduced, where consumers are horizontally differentiated by taste and firms vertically differentiated by quality location, within an equilibrium model of duopoly competition characterized by asymmetric fixed and variable costs. Firms choose quality location followed by prices but then may vertically re-locate their quality offerings based on changing horizontal consumer taste. A monopolistic equilibrium solution arises with firms achieving positive economic profits through price-quality markups exceeding marginal costs. Under strict inequality conditions, each firm acts as a monopolistic competitor within a range of quality choices governed by multiple relative differentiation outcomes. On the other hand, vertical re-location exhibits a resistance to change on the part of vertically located firms such that firms dislike quality re-location and prefer stable preferences in quality. Such resistance to change is overcome by firms re-locating their quality offerings to maximize monopolistic brand-space gains. It is argued that more horizontal differentiation may force more product differentiation by vertical quality relocation. A relative change in quality preferences may result in wider quality spreads in the market through vertical quality re-locations, even though the resistance to change arguments may still hold good.
Vertical Differentiation in Frictional Product Markets

Book Description
We consider a version of the imperfect competition model of Butters (1977), Varian (1980) and Burdett and Judd (1983) in which sellers make an ex-ante investment in the quality of their variety of the product. Equilibrium exists, is unique and is efficient. In equilibrium, search frictions not only cause sellers to offer different surpluses to buyers but also cause sellers to choose different qualities for their varieties. That is, equilibrium involves endogenous vertical differentiation. As search frictions decline, the market becomes more and more unequal as a smaller and smaller fraction of sellers produces varieties of increasing quality, offers increasing surplus to their customers, and captures an increasing share of the market, while a growing fraction of sellers produces varieties of decreasing quality. Gains from trade and welfare grow. Under some conditions, the growth rate of gains from trade and welfare is constant.
Branding Vertically Differentiated Product Lines

Book Description
The decision whether a multi-product firm offers its goods under a joint or separate brands is essential for its success. When selling vertically differentiated products, it needs to consider the interplay of branding spillovers, pricing and cannibalization. We study the problem of a firm selling vertically differentiated products deciding whether to sell its products under a joint or separate brands. The analysis accounts for the positive and negative spillover effects between jointly branded products previously established in the literature. Our findings suggest that joint branding is optimal when spillover effects are either high or low but not when they are intermediate. When spillover effects are low, firms jointly brand to save the cost of building a second brand. In contrast, when spillover effects are high, the firm chooses joints branding because it is inherently more profitable even if building additional brands is free. When spillover effects are intermediate, however, firms opt for separate branding despite the additional cost of building more brands. We also extend the analysis to investigate the effect of low-end strategic competition and find that this kind of competition pushes the multi-product line firm towards joint branding. Finally, our modeling approach explains why some firm use hybrid (endorsed) branding to dampen the spillover effects compared to pure joint branding.

Book Description
We analyze markets with both horizontally and vertically differentiated products under both monopoly and duopoly. In the base model with two consumer types, we identify conditions under which entry prompts an incumbent to expand or contract its low end of the product line. Our analysis offers a novel explanation for the widespread use of 'fighting brands' and 'product line pruning.' We also extend our analysis to asymmetric firms and three types of consumers and show that depending on the specific environment, entry may lead the incumbent to expand or contract the middle range of its product line (middle contracts). Our results are mainly driven by interactions between horizontal differentiation (competition) and vertical screening of consumers.
