  • 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.

  • Websphere Application Server V6: Web Container Problem Determination
    Redbooks Paper Javier Voos WebSphere Application Server V6: Web Container Problem Determination If users receive unexpected results in a Web browser (such as errors or incorrect information), you might have a problem with the Web components in the application. The runtime environment for Web components is called the Web container. This paper discusses techniques for diagnosing problems that can occur in the Web container. Potential symptoms of a Web container problem can include: Users are not able to access a Web component Unexpected behavior when running a Web component Errors when starting a Web component Problems with JSP™ compilation Errors or exceptions thrown when running a Web component Messages starting with SRVE (Web container), JSPG (JSPs), or JSFG (JSF) Problems areas that are related to the Web container also include session management problems and character encoding problems. Important: We recommend that you start your problem determination process by reading Approach to Problem Determination in WebSphere Application Server V6 at http://www.redbooks.ibm.com/redpapers/pdfs/redp4073.pdf. © Copyright IBM Corp. 2005. All rights reserved. ibm.com/redbooks 1 Introduction The Web container is a runtime environment for Web applications. It processes servlets, JSP files, and other types of server-side includes. The Web container also provides session management, static content processing and an inbound transport chain for HTTP requests. Each application server runtime has one logical Web container, which can be modified but not created or removed. Figure 1 illustrates the Web container and its place within the application server.
