Simulation Of The Colombian Firm Energy Market, Peter Cramton, Steven Stoft

Peter Cramton

We present a simulation analysis of the proposed Colombian firm energy market. The main purpose of the simulation is to assess the risk to suppliers of participation in the market. We also are able to consider variations in the market design, and assess the impact of alternative auction parameters. Three simulation models are developed and analyzed. The first model (Model 1) uses historical price data from October 1995 through May 2006 to assess the performance risk of hypothetical thermal and hydro generating units. The second model (Model 2) uses historical price and operating data to assess performance risk of the …

Public Healthcare: Changes Introduced When Implementing E-Procurement, Tommaso Federici

Federici Tommaso

The large and growing size of the healthcare public spending for goods and services worries the institutions of many European countries, including Italy, and asks for rationalization initiatives. In parallel, e-procurement solutions spread into Public Administrations (PA's) and introduce innovative processes, primarily in the purchasing phase.

In this scenario, e-procurement has the potential to enable significant efficiency improvements in the public healthcare sector, with the reduction of purchasing and administrative costs. However, most e-procurement initiatives met difficulties and did not fully delivered the expected benefits so far. This is mainly due to the healthcare procurement complexity, specific characteristics and peculiar …

Case Study Röhm Gmbh & Co. Kg - Consignment Depot Between Degussa Business Unit “Röhm“ And Basf Coatings Ag, Enrico Senger, Hubert Oesterle

Hubert Oesterle

Röhm produces special plastics, for, among others, the paint industry. In collaboration with BSAF Coatings, Röhm developed an extended Vendor Managed Inventory system that operates a consignment depot, takes on the actual and exact filling of tanks at the customer locations via telemetrics as well as advance forecasts, and passes on quality-related information to designated recipients, and includes the electronic billing of deliveries. The early access to data relevant to the planning process and process simplifications compensated for the additional operating costs. The closer relationship with the customer and their processes, as in the case of L’Oréal, is considered to …

New England’S Forward Capacity Auction, Peter Cramton

Peter Cramton

This note provides a brief description of New England’s Forward Capacity Auction (FCA) for the procurement of electricity capacity. The description is based on the 6 March 2006 Settlement Agreement. The description here presents a simpler description of the auction mechanics, and limits the presentation to the key elements relevant to someone providing software and other support to implement the primary auction. In addition, some motivation for the approach is given. The description here is not a software specification, but rather a high-level description of the auction. Many implementation details are yet to be resolved. These details will be resolved …

Global Data Synchronization – Hype Oder Lösung Für Das Überbetriebliche Produktstammdatenmanagement Zwischen Konsumgüterindustrie Und Handel?, Jan Schemm, Christine Legner, Hubert Oesterle

Hubert Oesterle

Abgestimmte Produktstammdaten bilden die Grundlage elektronischer Geschäftsbeziehungen zwischen Handels- und Industrieunternehmen. Sie sind damit ein Erfolgsfaktor für die Realisierung innovativer Geschäftsmodelle, die zu Umsatzsteigerungen und Kostenreduzierung entlang der Wertschöpfungskette führen. Obwohl Handel und Industrie sich schon vergleichsweise lange mit dem elektronischen Austausch von Produktdaten beschäftigen, konnten sich weder der EDI-basierte, bilaterale Stammdatenaustausch noch der multilaterale Ansatz über Datenpools durchsetzen. Seit Mitte 2004 verfolgt das Global Data Synchronization Network (GDSN) einen neuen Lösungsansatz, mit dem Ziel, einen m:n-fähigen elektronischen Produktstammdatenaustausch zu etablieren. Die Ankündigungen von führenden Handelsunternehmen wie Wal-Mart, Ahold oder Tesco sowie Konsumgüterherstellern wie Nestlé, Procter Gamble oder Kraft Foods …

The Convergence Of Market Designs For Adequate Generating Capacity, Peter Cramton, Steven Stoft

Peter Cramton

This paper compares market designs intended to solve the resource adequacy (RA) problem, and finds that, in spite of rivalrous claims, the most advanced designs have nearly converged. The original dichotomy between approaches based on long-term energy contracts and those based on short-term capacity markets spawned two design tracks. Long-term contracts led to call-option obligations which provide market-power control and the ability to strengthen performance incentives, but this approach fails to replace the missing money at the root of the adequacy problem. Hogan’s energy-only market fills this gap. On the other track, the short-term capacity markets (ICAP) spawned long-term capacity …

E-Contracting: Towards It-Enabled Collaboration Processes In Contract Management, Jan Schemm, Christine Legner, Hubert Oesterle

Hubert Oesterle

E-contracting implies pre-order electronic interaction between customers and suppliers engaging in business transactions. This paper examines electronic contracting from an interorganizational perspective. It derives a collaboration process architecture for contracting in retail and industrial companies and outlines key design decisions concerning a process-supporting system architecture. A case from the retail industry illustrates major problems with paper-based contracting processes currently practiced by most companies and emphasizes the usefulness and applicability of the developed framework in industrial practice. Finally, we present a research agenda towards a holistic framework providing support for retail and industry companies in deploying e-contracting solutions.

Introduction To Combinatorial Auctions, Peter Cramton, Yoav Shoham, Richard Steinberg

Peter Cramton

Combinatorial auctions are those auctions in which bidders can place bids on combinations of items, called “packages,” rather than just individual items. The study of combinatorial auctions is inherently interdisciplinary. Combinatorial auctions are in the first place auctions, a topic extensively studied by economists. Package bidding brings in operations research, especially techniques from combinatorial optimization and mathematical programming. Similarly, computer science is concerned with expressiveness of various bidding languages, and algorithmic aspects of the combinatorial problem. The study of combinatorial auctions thus lies at the intersection of economics, operations research, and computer science. In this book, we look at combinatorial …

The Clock-Proxy Auction: A Practical Combinatorial Auction Design, Lawrence M. Ausubel, Peter Cramton, Paul Milgrom

Peter Cramton

We propose the clock-proxy auction as a practical means for auctioning many related items. A clock auction phase is followed by a last-and-final proxy round. The approach combines the simple and transparent price discovery of the clock auction with the efficiency of the proxy auction. Linear pricing is maintained as long as possible, but then is abandoned in the proxy round to improve efficiency and enhance seller revenues. The approach has many advantages over the simultaneous ascending auction. In particular, the clock-proxy auction has no exposure problem, eliminates incentives for demand reduction, and prevents most collusive bidding strategies.

Combinatorial Auctions, Peter Cramton, Yoav Shoham, Richard Steinberg

Peter Cramton

A comprehensive book on combinatorial auctions―auctions in which bidders can bid on packages of items. The book consists of original material intended for researchers, students, and practitioners of auction design. It includes a foreword by Vernon Smith, an introduction to combinatorial auctions, and twenty-three cross-referenced chapters in five parts. Part I covers mechanisms, such as the Vickrey auction and the ascending proxy auction. Part II is on bidding and efficiency issues. Part III examines computational issues and algorithmic considerations, especially the winner determination problem―how to identify the (tentative) winning set of bids that maximizes revenue. Part IV discusses implementation and …

Dynamic Auctions In Procurement, Peter Cramton, Lawrence M. Ausubel

Peter Cramton

We study the theory and practical implementation of dynamic procurement auctions. We consider the procurement of many related items. With many related items, price discovery is important not only to reduce the winner’s curse, but more importantly, to simplify the bidder’s decision problem and to facilitate the revelation of preferences in the bids. Three auction formats are considered: simultaneous descending auctions are preferred if the items are not divisible, simultaneous clock auctions are desirable for procuring many divisible goods, and the clock-proxy auction is best if complementarities among items are strong and varied across the suppliers. We examine the properties …

Simultaneous Ascending Auctions, Peter Cramton, Yoav Shoham, Richard Steinberg

Peter Cramton

The simultaneous ascending auction has proved to be a successful method of auctioning many related items. Simultaneous sale and ascending bids enable price discovery, which helps bidders build desirable packages of items. Although package bids are not allowed, the auction format does handle mild complementarities well. I examine the auction design and its performance in practice.
