Antitrust Enforcement and the Consumer
Many consumers have never heard of antitrust laws, but when these laws are effectively and responsibly enforced, they can save consumers millions and even billions of dollars a year in illegal overcharges. Most States have antitrust laws, and so does the Federal Government. Essentially, these laws prohibit business practices that unreasonably deprive consumers of the benefits of competition, U.S. Department of Justice resulting in higher prices for inferior Washington, DC 20530 products and services. This pamphlet was prepared to alert consumers to the existence and importance of antitrust laws and to explain what you can do for antitrust enforcement and for yourself. 1. What Do the Antitrust Laws Do for the Consumer? Antitrust Antitrust laws protect competition. Free and open competition benefits consumers Enforcement by ensuring lower prices and new and better products. In a freely competitive and the market, each competing business generally Consumer will try to attract consumers by cutting its prices and increasing the quality of its products or services. Competition and the profit opportunities it brings also stimulate businesses to find new, innovative, and more efficient methods of production. Consumers benefit from competition through lower prices and better products and services. Companies that fail to understand or react to consumer needs may soon find themselves losing out in the competitive battle. When competitors agree to fix prices, rig bids, or allocate (divide up) customers, consumers lose the benefits of competition. The prices that result when competitors agree in these ways are artificially high; such prices do not accurately reflect cost and therefore distort the allocation of society’s resources. -

While the size of this phenomenon is to a large extent unknown, there are a growing number of firms using computer algorithms to improve their pricing models, customise services and predict market trends. -

I Cartels maximize profit by restricting the output of member firms to a level that the marginal cost of production of every firm in the cartel is equal to the market's marginal revenue and then charging the market-clearing price. F Behave like a monopoly I The need to allocate output among member firms results in an incentive for the firms to cheat by overproducing and thereby increase profit. -
Amazon's Antitrust Paradox
LINA M. KHAN Amazon’s Antitrust Paradox abstract. Amazon is the titan of twenty-first century commerce. In addition to being a re- tailer, it is now a marketing platform, a delivery and logistics network, a payment service, a credit lender, an auction house, a major book publisher, a producer of television and films, a fashion designer, a hardware manufacturer, and a leading host of cloud server space. Although Amazon has clocked staggering growth, it generates meager profits, choosing to price below-cost and ex- pand widely instead. Through this strategy, the company has positioned itself at the center of e- commerce and now serves as essential infrastructure for a host of other businesses that depend upon it. Elements of the firm’s structure and conduct pose anticompetitive concerns—yet it has escaped antitrust scrutiny. This Note argues that the current framework in antitrust—specifically its pegging competi- tion to “consumer welfare,” defined as short-term price effects—is unequipped to capture the ar- chitecture of market power in the modern economy. We cannot cognize the potential harms to competition posed by Amazon’s dominance if we measure competition primarily through price and output. Specifically, current doctrine underappreciates the risk of predatory pricing and how integration across distinct business lines may prove anticompetitive. These concerns are height- ened in the context of online platforms for two reasons. First, the economics of platform markets create incentives for a company to pursue growth over profits, a strategy that investors have re- warded. Under these conditions, predatory pricing becomes highly rational—even as existing doctrine treats it as irrational and therefore implausible. -

The Devil is in the Details – Implications of Samuel Bowles’ The Moral Economy for economics and policy research October 13 2017 Rachel Kranton Duke University The Moral Economy by Samuel Bowles should be required reading by all graduate students in economics. Indeed, all economists should buy a copy and read it. The book is a stunning, critical discussion of the interplay between economic incentives and preferences. It challenges basic premises of economic theory and questions policy recommendations based on these theories. The book proposes the path forward: designing policy that combines incentives and moral appeals. And, therefore, like such as book should, The Moral Economy leaves us with much work to do. The Moral Economy concerns individual choices and economic policy, particularly microeconomic policies with goals to enhance the collective good. The book takes aim at laws, policies, and business practices that are based on the classic Homo economicus model of individual choice. The book first argues in great detail that policies that follow from the Homo economicus paradigm can backfire. While most economists would now recognize that people are not purely selfish and self-interested, The Moral Economy goes one step further. Incentives can amplify the selfishness of individuals. People might act in more self-interested ways in a system based on incentives and rewards than they would in the absence of such inducements. The Moral Economy warns economists to be especially wary of incentives because social norms, like norms of trust and honesty, are critical to economic activity. The danger is not only of incentives backfiring in a single instance; monetary incentives can generally erode ethical and moral codes and social motivations people can have towards each other. -

Monopoly Pricing in a Time of Shortage James L Serota* I. INTRODUCTION Traditionally, the electric power industry has been heavily regulated at both the federal and state levels. Recently, the industry has been evolving towards increasing emphasis on market competition and less pervasive regulation. Much of the initial impetus for change has occurred during periods of reduced demand and increased supply. More recently, increases in demand and supply shortages have led to brownouts, rolling blackouts, price spikes and accusations of "price gouging."' The purpose of this paper is to examine the underlying economic and legal bases for regulation and antitrust actions, and the antitrust ground rules for assessing liability for "monopoly pricing in times of shortage." In this author's view, price changes in response to demand are the normal reaction of a competitive market, and efforts to limit price changes in the name of "price gouging" represent an effort to return to pervasive regulation of electricity. -
Collusion Constrained Equilibrium
Theoretical Economics 13 (2018), 307–340 1555-7561/20180307 Collusion constrained equilibrium Rohan Dutta Department of Economics, McGill University David K. Levine Department of Economics, European University Institute and Department of Economics, Washington University in Saint Louis Salvatore Modica Department of Economics, Università di Palermo We study collusion within groups in noncooperative games. The primitives are the preferences of the players, their assignment to nonoverlapping groups, and the goals of the groups. Our notion of collusion is that a group coordinates the play of its members among different incentive compatible plans to best achieve its goals. Unfortunately, equilibria that meet this requirement need not exist. We instead introduce the weaker notion of collusion constrained equilibrium. This al- lows groups to put positive probability on alternatives that are suboptimal for the group in certain razor’s edge cases where the set of incentive compatible plans changes discontinuously. These collusion constrained equilibria exist and are a subset of the correlated equilibria of the underlying game. We examine four per- turbations of the underlying game. In each case,we show that equilibria in which groups choose the best alternative exist and that limits of these equilibria lead to collusion constrained equilibria. We also show that for a sufficiently broad class of perturbations, every collusion constrained equilibrium arises as such a limit. We give an application to a voter participation game that shows how collusion constraints may be socially costly. Keywords. Collusion, organization, group. JEL classification. C72, D70. 1.

Predatory Pricing, a Case Study: Matsushita Electric Industries Co. V. Zenith Radio Corporation
PREDATORY PRICING, A CASE STUDY: MATSUSHITA ELECTRIC INDUSTRIES CO. V. ZENITH RADIO CORPORATION M. STEVEN WAGLE INTRODUCTION There is an abundance of predatory pricing theories. Scholars have created a barrage of rules and thresholds designed to detect un- lawful predatory practices. The most influential work on predatory practice was written almost thirty years ago by John S. McGee.1 Mc- Gee showed that although it was widely believed that the Standard Oil Company used predatory pricing in its virtual monopolization of the oil refining market, there was no hard evidence to show that Standard Oil in fact employed such pricing. Since McGee, many scholars have reviewed the theories of pric- ing, and recent literature on the law and economics of antitrust has devoted increasing attention to this issue.2 There has also been an outpouring of cost-based rules appearing in court opinions dealing with predatory pricing.3 These rules can essentially be attributed to t J.D., Washburn University, 1986; M.A., Wichita State University, 1986; B.A., Unmversity of Kansas, 1980.
