TL;DR: In this paper, the authors used data collected in April 1999 on the prices of 107 books in thirteen online and two physical bookstores and found similar average prices online and in physical stores and substantial price dispersion online.
Abstract: Two conflicting predictions have emerged regarding the effect of low–cost information on price. The first states that all Internet retailers will charge the same low price for mass produced goods. The second states that Internet retailers will differentiate to avoid intense price competition. Using data collected in April 1999 on the prices of 107 books in thirteen online and two physical bookstores, we find similar average prices online and in physical stores and substantial price dispersion online. Analysis of product differentiation yields no clear results. The substantial premium charged by Amazon provides indirect evidence of product differentiation.
TL;DR: The authors developed a dynamic model of nonprice competition in an oligopolistic industry and used it to analyze advertising competition in the U.S. cigarette industry, showing that firm advertising primarily affects the level of market demand, with a firm's effect on rival firms' market shares arising through variations in the number of brands sold.
Abstract: This article develops a dynamic model of nonprice competition in an oligopolistic industry and uses it to analyze advertising competition in the U.S. cigarette industry. The model generalizes existing studies by allowing advertising to affect both firm market shares and the total size of the market. The model also allows dynamic conjectural variations to arise from the intertemporal links created by the durability of advertising. We use these dynamic conjectural variations to distinguish alternative models of competitive interaction. We estimate the complete model of firm production, demand, and advertising choice by using data for U.S. cigarette producers. The results indicate that firm advertising primarily affects the level of market demand, with a firm's effect on rival firms' market shares arising through variations in the number of brands sold. Empirical results on firm behavior suggest that firms act as if their advertising choices will alter the future advertising choices of rival firms in both the high-tar and low-tar cigarette markets.(This abstract was borrowed from another version of this item.)
TL;DR: In the absence of free entry, and both the medallions required of taxis and the seats of New York Stock Exchange members are fixed in number, the question arises: will any monopoly profit achieved by suppressing price competition be eliminated by non-price competition?.
Abstract: When a uniform price is imposed upon, or agreed to by, an industry, some or all of the other terms of sale are left unregulated. The setting of taximeter rates still allows competition in the quality of the automobile. The fixing of commission rates by the New York Stock Exchange still allows brokerage houses to compete in services such as providing investment information. If additional firms may enter such a price-regulated field at no cost disadvantage, profits resulting from the price regulation will be eliminated in long-run equilibrium. But in the absence of free entry-and both the medallions required of taxis and the seats of New York Stock Exchange members are fixed in number-the question arises: Will any monopoly profit achieved by suppressing price competition be eliminated by nonprice competition? We may emphasize that a symmetrical question arises if the firms are required to sell the same product (that is, have the same non-price variable) but are allowed to compete freely in prices. For example, let every seller of gasoline provide the identical product. Will free price competition eliminate any monopoly profits arising from agreement not to compete in the quality of gasoline? Economists generally attribute much more efficacy to price than to non-price competition without giving any clear explanation of the asymmetry of the two kinds of competition. Let us take advertising as the prototype of non-price variables. A previously competitive industry may form a cartel and (1) fix advertising jointly and allow competition in price or (2) fix price jointly and allow competition in advertising. We examine the two cases in turn. Let each firm be operating, under competition, at output Q0 and price P0 (Fig. 1). Upon colluding on advertising, marginal costs-which include the costs of advertising-are reduced at every output for each firm.1 The 1 Economists who find it uncomfortable to discuss advertising in a competitive industry can substitute another non-price variable (such as durability of product, investment advice, or warranties of free repairs) with only terminological effects.
TL;DR: In this paper, Ireland examines the three stages of the supply side of a market: the decision of firms to participate in the market; the selection of specific product characteristics in design, function and quality; and the formulation and execution of pricing and advertising strategies.
Abstract: This volume examines the three stages of the supply side of a market: the decision of firms to participate in the market; the selection of specific product characteristics in design, function and quality; and the formulation and execution of pricing and advertising strategies. Focusing on the influence of the product selection stage, Ireland looks at the ways in which consumers' demands for variety affect the oligopoly marketing games. He examines the various strategies adopted by firms to deter potential competitors: advertising, quality competition, or "creaming" the market of those customers willing to pay top dollar. This is an up-to-date treatment of key topics in the new industrial economics.
TL;DR: In this article, the authors argue that a paradigmatic change in competition policy is needed and empirically under way to cope with the challenges posed by economically strong online platforms and their big-data-based business models.
