Modeling Electricity Auctions

The recent debates over discriminatory versus uniform-price auctions in the UK and elsewhere have revealed an incomplete understanding of the limitations of some popular auction models when applied to real-world electricity markets. This has led certain regulatory authorities to prefer discriminatory auctions on the basis of reasoning from models which are not directly applicable to any existing electricity market. Vickrey auctions, although often recommended by economists, have also been ignored in these debates. This article describes the approach which we believe should be taken to analyzing these issues

Game Study on Collusion in the First-price Sealed-bid Reverse Auction

Collusion between suppliers in reverse auctions may damage buyers’ benifits and then lower efficiency of resource allocation. Under first-price sealed-bid reverse auction mechanism, suppliers\u27 equilibrium bidding strategy and buyers\u27 revenue loss was analyzed considering collusion. Then some general conclusions were given: suppliers\u27 bidding strategy is relevant to some factors such as valuation costs, the number of suppliers and Cartel; the number of suppliers and Carter can lead to buyers revenue loss. Finally, considering two different kinds of distribution function, the strategies of improving buyer’s revenue were discussed

The Market for Preclusion in Merger Litigation

The recent finding that corporate litigation involving Delaware companies very often takes place outside of Delaware has disturbed the long-settled understanding of how merger litigation works. With many, even most, cases being filed and ultimately resolved outside of Delaware, commentators warn that the trend is a threat to shareholders, to Delaware, and to the integrity of corporate law generally. Although the out-of-Delaware trend suggests that litigants are seeking to use the procedural rules of other jurisdictions to their advantage, we argue that the result need not threaten the interests of any of the stakeholders in deal litigation. We reframe the process of resolving merger litigation as a market for preclusion, in which plaintiffs seek to sell and defendants seek to buy an important element of transactional certainty. Moreover, this market has the potential to efficiently process and price shareholder complaints while also providing benefits to Delaware and to corporate law more generally. We are not blind to reality, however, and also address how a well-functioning market for preclusion can be distorted by the opportunistic conduct of plaintiffs’ and defense attorneys alike. Greater judicial oversight is necessary to preserve the benefits of this market while preventing the distortions brought on through opportunistic conduct. In order to make this a reality, however, judges in different courts must have a means of communicating and coordinating across state lines. We therefore offer a theory of horizontal comity in which judges build trust and cooperation through communication across jurisdictional boundaries. We use this theory to suggest a set of concrete policy proposals designed to provide for a more efficient market for preclusion

Universal mobile telephone standard (UMTS) licensing : recent European experience and the South African case by Nicolas Theopold.

Bibliography: leaves 62-64.The telecommunications industry was long regarded to be one of "natural monopoly". Technological development has, however, changed the situation in the industry fundamentally: with the introduction of digital wireless telephony (also called "GSM " or "second generation (2G)), competition could effectively be introduced into the industry, as the new networks rely on antennas instead of fixed cable networks. This made it possible, and in the presence of large numbers of subscribers necessary, to build multiple mobile telephone networks in one country

Natural Monopoly and the Contestable Markets Hypothesis: Some Preliminary Results from Laboratory Experiments

The concept of natural monopoly is one of the most familiar in economics. Many supposed natural monopolies are the object of widespread state, local, and federal regulation. It was in addressing issues of public utility regulation that Demsetz laid the foundation for an alternative scenario for decreasing cost markets. Demsetz\u27s article promoted a debate over whether a formal auction system might provide a practical approach to monopoly control. This literature is rich in examining the practical difficulties of implementing such an institution. The important characteristic of the contestable markets hypothesis, as we interpret it, is that at least two firms bid, in the sense of Demsetz, directly for buyer purchases

A Welfare Analysis of Spectrum Allocation Policies

Analysis of spectrum allocation policies in the economics literature focuses on competitive bidding for wireless licenses. Auctions generating high bids, as in Germany and the UK, are identified as "successful," while those producing lower receipts, as in Switzerland and the Netherlands, are deemed "fiascoes." Yet, even full and costless extraction of license rents does not map directly to social welfare, because spectrum policies creating rents impose social costs. For example, rules favoring monopoly market structure predictably increase license values, but reduce welfare. This paper attempts to shift analytical focus to the relationship between spectrum policy (including license auctions) and efficiency in output markets. In cross-country comparisons of performance metrics in mobile telephone service markets, empirical estimates suggest that countries that auction licenses do not achieve lower prices or higher levels of output than other nations. Rather, countries allocating greater bandwidth to licensed operators and achieving more competitive market structures realize demonstrable social welfare benefits. These gains generally dominate efficiencies associated with license sales. Policies to increase auction revenues, such as reservation prices and subsidies for weak bidders, should be evaluated in this light.

A Comparison of Auctions and Multilateral Negotiations

We compare first-price auctions to an exchange process that we term \u27multilateral negotiations.\u27 In multilateral negotiations, a buyer solicits price offers for a homogeneous product from sellers with privately known costs, and then plays the sellers off one another to obtain additional price concessions. Using the experimental method, we find that with four sellers, transaction prices are statistically indistinguishable in the two institutions, but with two sellers, prices are higher in multilateral negotiations than in first-price auctions. The institutions are equally efficient with two sellers, but multilateral negotiations are slightly more efficient with four sellers

The Fishery as a Watery Commons: Lessons from the Experiences of Other Public Policy Areas for U.S. Fisheries Policy

Open access, combined with modern technologies of fishing, has created serious problems of overfishing and threatens the sustainability of many U.S. fisheries. The common pool problem -- the ocean version of "the tragedy of the commons" -- is the root cause of the overfishing. The major regulatory policies of the past few decades that have tried to address overfishing -- restrictions on fishing methods and inputs (in essence, "command and control" regulation) -- have largely been failures. Indeed, they have often perversely exacerbated fisheries' overfishing problems by encouraging "fishing derbies" or "races for the fish." Fisheries are not alone in facing a common pool problem. Other areas of the U.S. economy have confronted similar problems, and public policies have developed to deal with them. This paper discusses seven of these other areas: the use of the electromagnetic spectrum, the control of sulfur dioxide emissions by electric utilities, grazing on public lands, forest logging on public lands, oil-gas-coal extraction from public lands and offshore waters, hard rock mineral (metal) mining, and surface water usage.Important lessons can be gleaned from the policies that have been developed in these other areas, and this paper applies those lessons to the design of U.S. fisheries policy.

Auctioning of CO2 Emission Allowances in Phase 3 of the EU Emissions Trading Scheme

The Climate action and renewable energy package proposed by the European Commission in the beginning of 2008 suggests auctioning as basic principle for allocation for the upcoming third trading phase of the EU Emissions Trading Scheme that runs from 2013 to 2020. Overall, it is estimated that at least two third of the total quantity of allowances will be auctioned in 2013, to be increased to 100 % by 2020. In this paper, we emphasize the importance of a properly chosen auction design as the significantly higher auction share, compared to the past and current trading phase, is expected to yield a thin secondary market for CO2 allowances. We elaborate main criteria that a viable auction design is supposed to fulfil and propose a specific auction design for the third trading phase. The auction we recommend is a simultaneous dynamic uniform double auction. -- Die Europäische Kommission hat in ihrem Klima- und Energiepaket vom Januar 2008 eine Weichenstellung für den europäischen Emissionshandel vorgeschlagen. Bislang wurden die Zertifikate an die betroffenen Unternehmen aus den energieintensiven Sektoren kostenfrei vergeben. Nach den Plänen der Kommission sollen Stromproduzenten ab 2013 alle benötigten Zertifikate ersteigern müssen. Unternehmen aus anderen energieintensiven Branchen sollen zunächst nur 20 % ersteigern, in 2020 dann 100 %. Da insgesamt mindestens zwei Drittel aller Zertifikate versteigert werden, ist zu erwarten, dass der freie Markt für Zertifikate ab 2013 deutlich dünner sein wird als dies bisher der Fall ist. Aus diesem Grund gewinnt das Design der Auktion an Bedeutung, denn vom Auktionspreis, der die Knappheit an Zertifikaten signalisieren soll, werden wichtige Investitionsentscheidungen in CO2-arme Technologien abhängen. Eventuelle Fehler im Auktionsdesign können, wenn die Zertifikate überwiegend versteigert werden, nicht mehr durch einen liquiden freien Markt geheilt werden.climate policy,emissions trading,auction design
