Many Internet companies, such as eBay and Yahoo!, have launched online auction systems. Many researchers have studied the security problems of electronic auction systems, but few of them are multi-attribute-based. In 2014, Shi proposed a provable secure, sealed-bid, and multi-attribute auction protocol based on the semi-honest model. We evaluated this protocol and found that it has some design weaknesses and is vulnerable to the illegal operations of buyers, which results in unfairness. In this paper, we improved this protocol by replacing the Paillier’s cryptosystem with the elliptic curve discrete (ECC), and we designed a novel, online, and multi-attribute reverse-auction system using the semi-honest model. In our system, sellers’ identities are not revealed to the buyers, and the buyers cannot conduct illegal operations that may compromise the fairness of the auction. -

Common-Value Auctions with Liquidity Needs: an Experimental
CommonValue Auctions with Liquidity Needs: An Experimental Test of a Troubled Assets Reverse Auction Lawrence M. Ausubel, Peter Cramton, Emel Filiz‐Ozbay, Nathaniel Higgins, Erkut Ozbay, and Andrew Stocking* 21 May 2009 Abstract We experimentally test alternative auction designs suitable for pricing and removing troubled assets from banks’ balance sheets as part of the financial rescue. Many individual securities or pools of securities are auctioned simultaneously. Securities that are widely held are purchased in auctions for individual securities. Securities with concentrated ownership are purchased as pools of related securities. Each bank has private information about its liquidity need and the true common value of each security. We study bidding behavior and performance of sealed‐ bid uniform‐price auctions and dynamic clock auctions. The clock and sealed‐bid auctions resulted in similar prices. However, the clock auctions resulted in substantially higher bank payoffs, since the dynamic auction enabled the banks to better manage their liquidity needs. The clock auctions also reduced bidder error. The experiments demonstrated the feasibility of quickly implementing simple and effective auction designs to help resolve the crisis. (JEL D44, C92, G01, G21. Keywords: financial crisis, uniform‐price auction, clock auction, market design, experiments, troubled assets, TARP.) 1 Introduction On 3 October 2008, the US Congress passed and the President signed the Emergency Economic Stabilization Act of 2008 (Public Law 110‐343). The Act established the $700 billion Troubled Asset Relief Program (TARP). It authorized the US Treasury to purchase troubled assets in order to restore liquidity to financial markets, favoring. the use of market mechanisms such as reverse auctions for asset purchases. -

Using Request for Proposal in Sourcing Practices
USING REQUEST FOR PROPOSAL IN SOURCING PRACTICES Case study: CPS Color Group Oy LAHTI UNIVERSITY OF APPLIED SCIENCES Degree programme in International Business Bachelor’s Thesis 28 October 2013 Kim Ngan Hoang Pham-Keskinen Lahti University of Applied Sciences Degree Programme in International Business PHAM-KESKINEN, KIM NGAN Using Request for Proposal in Sourcing HOANG Practices Case study: CPS Color Group Oy Bachelor’s Thesis in International Business, 49 pages, 1 page of appendices Autumn 2013 ABSTRACT Under the pressure of increasing costs efficiencies in a volatile economic environment, procurement managers are forced to make the most sensible supplier selection decision. Strategic sourcing is an optimum approach that aligns procurement projects with the best suppliers. Such approach ensures all project needs are satisfied while releases the highest savings opportunities. Request for proposal (RFP) is a strategic sourcing tool. It is a means of communication to inform prospective suppliers about the needs and requirements of a procurement project and encourage them to submit proposals that best satisfy these needs and requirements. The proposals will be evaluated and rated using an objective and structured scoring system to select the best supplier for the project being procured. This thesis is conducted to assist the case company – CPS Color Group Oy in using RFP in their sourcing practices. The theoretical part of the study introduces steps in a strategic sourcing process and describes how an RFP can be employed in the process. Following are theories concerning different aspects of an RFP including its usage, advantages, content and proposal evaluation method. In the empirical part, the sourcing practices of the case company in both direct spend and indirect spend categories are explored. -

Spectrum Auctions from the Perspective of Matching
Spectrum Auctions from the Perspective of Matching Paul Milgrom and Andrew Vogt May 5, 2021 1 Introduction In July 1994, the United States Federal Communications Commission (FCC) conducted the first economist-designed auction for radio spectrum licenses. In the years since, governments worldwide have come to rely on auction mecha- nisms to allocate { and reallocate { rights to use electromagnetic frequencies. Over the same period, novel uses for spectrum have dramatically increased both the demand for licenses and auction prices, drawing continued attention to the nuances of spectrum markets and driving the development of spectrum auction design. In August 2017, the FCC completed the Broadcast Incentive Auction, a two-sided repurposing of an endogenously-determined quantity of spectrum that ranks among the most complex feats of economic engineering ever under- taken. The next generations of mobile telecommunications are poised to extend this growth, and to demand further innovation in the markets and algorithms that are used to assign spectrum licenses. What does all of this have to do with matching theory? Spectrum auctions differ from canonical matching problems in meaningful ways. Market designers often emphasize that a key element of matching markets is the presence of preferences on both sides of the market. In a marriage, for example, it is not enough that you choose your spouse; your spouse must also choose you. This two-sided choice structure applies also to matches between students and schools and between firms and workers, but not to matches between telecommunications companies and radio spectrum licenses. It is a different matching element that is often critically important in ra- dio spectrum auctions. -

Auctioning One Item
Auctioning one item Tuomas Sandholm Computer Science Department Carnegie Mellon University Auctions • Methods for allocating goods, tasks, resources... • Participants: auctioneer, bidders • Enforced agreement between auctioneer & winning bidder(s) • Easily implementable e.g. over the Internet – Many existing Internet auction sites • Auction (selling item(s)): One seller, multiple buyers – E.g. selling a bull on eBay • Reverse auction (buying item(s)): One buyer, multiple sellers – E.g. procurement • We will discuss the theory in the context of auctions, but same theory applies to reverse auctions – at least in 1-item settings Auction settings • Private value : value of the good depends only on the agent’s own preferences – E.g. cake which is not resold or showed off • Common value : agent’s value of an item determined entirely by others’ values – E.g. treasury bills • Correlated value : agent’s value of an item depends partly on its own preferences & partly on others’ values for it – E.g. auctioning a transportation task when bidders can handle it or reauction it to others Auction protocols: All-pay • Protocol: Each bidder is free to raise his bid. When no bidder is willing to raise, the auction ends, and the highest bidder wins the item. All bidders have to pay their last bid • Strategy: Series of bids as a function of agent’s private value, his prior estimates of others’ valuations, and past bids • Best strategy: ? • In private value settings it can be computed (low bids) • Potentially long bidding process • Variations – Each agent pays only part of his highest bid – Each agent’s payment is a function of the highest bid of all agents • E.g.
