英国和德国可再生能源产业激励政策和实施效果的比较

英国和德国都是国际上控制气候变化和开发可替代能源的积极倡导者,但目前,两国在可再生能源的开发和利用方面存在较大的差距:截至2012年,英国和德国可再生能源在最终能源消费中的占比分别为4.1%和12.6%;可再生能源的总装机容量分别为15538和76017MW。究其原因,主要是由两国不同的能源政策造成的,英国采取的是类似配额制的可再生能源义务令制度,而德国采用的是固定上网电价机制。事实证明,德国的入网电价体系优于英国的可再生能源义务令,因为它在一定时期内能为可再生能源发电商提供稳定的回报。英国尽管在可再生能源的开发和利用方面落后于德国,但英国自然条件优越,开发利用可再生能源的潜力巨大,加上政府的积极努力,英国可再生能源产业的发展有望得到较大改观。     

Creating competition out of thin air: An experimental study of right-to-choose auctions

This paper presents an experimental study of a mechanism that is commonly used to sell multiple heterogeneous goods. The novel feature of this procedure is that instead of selling each good in a separate auction, the seller executes a single auction in which buyers, who may be interested in completely different goods, compete for the right to choose a good. We provide experimental evidence that a Right-to-Choose (RTC) auction can generate more revenue than the theoretically optimal auction. Moreover, in contrast to the “optimal” auction, the RTC auction is approximately efficient in the sense that the surplus it generates is close to the maximal one. Furthermore, a seller who would like to retain some of his goods can generate more revenue with a restricted RTC auction in which not all rights-to-choose are sold, than with the theoretically optimal auction.     

Multiple-unit English auctions

This paper examines the outcome of an ascending-price multiple-unit auction. Two bidders, facing continuous, downward-sloping demand functions, participate in the auction of some divisible objects. The auctioneer starts the process by announcing an initial price and asking both bidders to submit sealed-bids of desired quantities. The auctioneer increases the price until the total amount bid for is less than the total supply. We compute the outcome of this auction game under full information and suggest that this mechanism may not maximize expected revenue.     

The share of the global energy mix: Signs of convergence?

This paper investigates the convergence behaviour regarding the share of global energy mix, as measured by primary energy consumption. Recent studies that employ stationary tests of panel data suggest that such data support the convergence hypothesis; however, some drawbacks exist, as these studies rely on methods that do not necessarily imply a sufficient condition for convergence. This paper adopts the concept of relative convergence as proposed by Phillips and Sul (2007), which employs a time‐varying, idiosyncratic component. We choose to focus on various sources’ global primary energy consumption and investigate the long‐ run dynamic behaviour by source. The key finding of this paper is that two distinct clubs of convergence of energy can be determined: renewable and non‐renewable energy clubs of convergence.     

意大利能源概况及可再生能源的开发和利用

意大利能源非常短缺,石油和天然气储量严重不足,煤矿已经关闭,核能禁止使用,电力仍需依靠进口。据意大利新技术能源与环境委员会（ENEA）最新统计,2007年意能源对外依存度为85．6％,远远超出欧盟的平均水平。本文详细介绍了意大利传统能源的生产、进口及消费情况,同时对意大利可再生能源的开发利用也做了详尽的分析。     

美国可再生能源政策研究

美国政府从20世纪70年代开始重视可再生能源,但是,由于可再生能源初期运营成本高,风险大,其低排放与可循环等优势不能体现在价格上,因此,与传统能源相比没有竞争优势.为此,美国联邦政府相继出台了一系列的法律、法规,地方政府也制定了配套的经济激励政策,从而促进可再生能源在美国的推广应用和产业发展.本文介绍了美国联邦政府及地方政府在可再生能源方面的有关政策,希望对我国有所启示.

Ascending auctions for multiple objects: the case for the Japanese design

Summary. We consider two ascending auctions for multiple objects, namely, an English and a Japanese auction, and derive a perfect Bayesian equilibrium of the Japanese auction by exploiting its strategic equivalence with the survival auction, which consists of a finite sequence of sealed-bid auctions. Thus an equilibrium of a continuous time game is derived by means of backward induction in finitely many steps. We then show that all equilibria of the Japanese auction induce equilibria of the English auction, but that many collusive or signaling equilibria of the English auction do not have a counterpart in the Japanese auction.Received: 2 September 2004, Revised: 20 April 2005, JEL Classification Numbers: C72, D44.Fabrizio Germano: Correspondence toWe are indebted to Philippe Jehiel for useful discussions and to Nicolas Vieille for suggestions in the proof of Proposition 2; we also thank seminar audiences in Athens, Basel, Beer-Sheva, Berlin, Brussels, Cambridge, Edinburgh, Exeter, Lausanne, Lisbon, London, Louvain-la-Neuve, Namur and Tel Aviv.

韩国新能源和可再生能源的发展

韩国是世界第10大能源消费国和世界第5大石油进口国.韩国国内能源资源贫乏,能源严重依赖进口,2007年能源进口依存度达96.7%.为了应对近些年石油价格飙升和全球气候变化的挑战,韩国政府调整了能源发展战略,强调能源供应多样化,将新能源和可再生能源作为国家能源战略的重要组成部分;目标是在2011年前使新能源和可再生能源占全国能源供应的5%,2020年扩大到10%.为了促进新能源和可再生能源的快速发展,韩国政府制定了相关的法律、计划和经济激励政策等.     

Truthful approximation mechanisms for restricted combinatorial auctions

When attempting to design a truthful mechanism for a computationally hard problem such as combinatorial auctions, one is faced with the problem that most efficiently computable heuristics can not be embedded in any truthful mechanism (e.g. VCG-like payment rules will not ensure truthfulness).We develop a set of techniques that allow constructing efficiently computable truthful mechanisms for combinatorial auctions in the special case where each bidder desires a specific known subset of items and only the valuation is unknown by the mechanism (the single parameter case). For this case we extend the work of Lehmann, O'Callaghan, and Shoham, who presented greedy heuristics. We show how to use If-Then-Else constructs, perform a partial search, and use the LP relaxation. We apply these techniques for several canonical types of combinatorial auctions, obtaining truthful mechanisms with provable approximation ratios.
