Geradin","doi":"10.1093/JECLAP/LPP016","DOIUrl":"https://doi.org/10.1093/JECLAP/LPP016","url":null,"abstract":"On 21 September 2009, the European Commission published a provisional non-confidential version of its 13 May 2009 Decision in which it condemned Intel to a record fine of € 1.06 billion on the ground that it had granted conditional rebates and payments to a number of OEMs and a large retailer of consumer electronics purchasing its x86 CPUs, and that it had paid OEMs to delay, cancel or in some other way restrict the commercialization of specific AMD-based products. This paper shows that the Commission Decision contains a number of flaws. They include the facts that the Decision: (i) relies in substance on a per se prohibition of conditional rebates recognized by the formalistic case-law of the Community courts, notwithstanding that the Commission had clearly indicated in various important policy documents, including its Guidance Paper on Article 82 EC, its intention to move away from this approach for an effects-based analysis; (ii) states, contrary to sound policy, that it need not conduct an “as efficient competitor” test, but conducts a misguided one anyway; (iii) insufficiently supports its speculative theory that the OEMs’ purchasing policy was influenced by their understanding of Intel’s alleged intention to reduce or eliminate their rebates should they buy x86 CPUs from AMD; (iv) fails to demonstrate its contention that Intel’s rebates harm competition and consumers; and (v) conducts an excessively restrictive analysis of the efficiencies created by Intel’s rebates. The Intel decision thus stands for the dangerous proposition that any dominant firm is at risk under Article 82 EC if there exists evidence that employees of a customer believe that reducing present purchases from it could have repercussions with regard to the availability and terms of future purchases, even if the belief is ambiguous, equivocal or contrary to written assurances of the firm or its executives, and without any showing of foreclosure. While the foregoing may be considered as an overstatement and that an “agreement” on conditions (not a mere unilateral belief on the part of the customer) is necessary to find a violation, the Commission accords itself so much latitude on how it collects, interprets and weighs evidence that the distinction is illusory. The compatibility of the Commission Decision with EC competition law will now be examined by the Court of First Instance of the European Communities to which Intel lodged an appeal. Because of the wide-ranging implications of this Decision, not only for Intel but for all large corporations having to negotiate price incentives with their customers, it is to be hoped that the Court of First Instance of the EC will review this decision carefully and hold the Commission to the same rigorous standards it has applied in the merger control area. An important question (that will not be addressed by the Court of First Instance, but which is nevertheless relevant from a policy standpoint) is whether antitrust intervention was at","PeriodicalId":105752,"journal":{"name":"IRPN: Innovation & Regulatory Law & Policy (Topic)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122034071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While we may disagree about the stimulus package, we believe that it is important to implement mechanisms that make stimulus spending as efficient as possible. To that end, we have come together to encourage the National Telecommunications Information Agency (NTIA) and Rural Utilities Service (RUS) to adopt auction mechanisms to allocate broadband stimulus grants. The broadband stimulus NOI asks which mechanisms NTIA and RUS should use to distribute grants and how those mechanisms address shortcomings in traditional grant and loan programs. In this note we explain why procurement auctions are more efficient and more consistent with the stimulus goals of allocating funds quickly than a traditional grant review process. We recommend that NTIA/RUS use procurement auctions to distribute at least part of the stimulus funds. The American Recovery and Reinvestment Act (ARRA) requires NTIA/RUS to distribute $7.2 billion in broadband subsidies. The broadband component of the Act has dual, and not entirely consistent, objectives of providing immediate economic stimulus and improving broadband service. NTIA/RUS faces a formidable challenge in determining how to spend the money quickly and efficiently in ways that meet these goals. The traditional grant application process is long, complicated, and involves subjective and arbitrary decisions regarding which projects to fund. In other words, requesting and reviewing grant applications is not an effective way to implement the plan. Procurement auctions, in contrast, provide a mechanism that can allocate grant money quickly, efficiently, and according to well-defined rules. As a result, procurement auctions offer NTIA/RUS the most promising method of maximizing broadband improvement while also creating some level of “temporary, timely, and targeted” stimulus. We therefore strongly recommend that NTIA/RUS adopt procurement auctions as its preferred method of distributing grants. This memo has three parts. First, it explains why the traditional grant application process is unsuitable for this task and why procurement auctions are better suited. Second, it sketches out a procurement auction plan. This plan is intended to be a starting point from which auction design experts would proceed to build and implement a fully functional auction. Finally, we explain that even if policymakers are skeptical of procurement auctions, one could be implemented quickly as part of an initial tranche of stimulus funding in order to test its efficacy relative to traditional approaches. This approach would allow NTIA/RUS to quickly expand upon or modify the procurement auction program in subsequent funding rounds.","PeriodicalId":105752,"journal":{"name":"IRPN: Innovation & Regulatory Law & Policy (Topic)","volume":"37 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126959601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supported by caller identification facilities and built-in address books that most mobile phones come equipped with, the practice allows mobile users to pass on the cost of communication to others,. This has allowed many at the bottom of the economic pyramid (or BOP) to fulfill a variety of communication needs at virtually no cost. This paper explores the use of missed calling as a means of cost-minimization at the BOP in five emerging Asian countries. The paper draws on findings from a five-country, 8600 sample study conducted in 2006. Contradictory to much of the existing literature, this article finds that the practice is as popular among non-BOP mobile owners as with BOP mobile owners. What may have originated as a cost-minimizing strategy may in fact now have become a ‘strategy of convenience’ used at all levels of the economic pyramid.","PeriodicalId":105752,"journal":{"name":"IRPN: Innovation & Regulatory Law & Policy (Topic)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128397085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a Network Neutrality proposal to be justified, the purported benefits of that proposal must exceed the costs, including the inefficiency in network design as well as the risk of increased industry concentration and market power. Publicly available cost studies show that if IP video services increase in popularity, the cost of providing a residential subscriber a \"stupid\" network that is video-capable could reach $300 to $400 per month more than an \"intelligent\" network, which would certainly put broadband out of the reach of many Americans. We also present a simple model which shows that voluntary investments in network efficiency always improve consumer and social welfare - even if, as some Network Neutrality proponents contend, stupid networks are otherwise preferred by consumers.","PeriodicalId":105752,"journal":{"name":"IRPN: Innovation & Regulatory Law & Policy (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131133834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I show that industry patents are associated with more firm-level equity issues and reduced leverage. Firms in industries with more patents issue more equity at a given point in time. Within industries, however, equity issuers are not patent recipients themselves. Remarkably, such equity issuers do not increase investments, dividends, or acquisitions. Rather, they hold the proceeds of equity issues in cash reserves. Finally, patent recipients earn high positive abnormal returns. These findings cast doubt on traditional views of patents as signals of investment opportunities or reductions of information asymmetry. The evidence is instead consistent with the view that patents are a catalyst for investor sentiment.","PeriodicalId":105752,"journal":{"name":"IRPN: Innovation & Regulatory Law & Policy (Topic)","volume":"21-22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131788890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
