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 …

Variations In Dropout Rates Across Virginia, Joshua K. Bowser

Undergraduate Theses and Capstone Projects

Using Ordinary Least Squares (OLS) regression analysis, this study attempts to capture variation in dropout rates across Virginia counties and cities. With the respective dropout rates as the dependent variable, seven independent variables are used accordingly in order to provide as much explanatory power as possible. At the 10 percent significance level, four of seven variables are statistically significant with an adjusted R2 of .374. Important policy implications can be derived from the model and its statistically significant variables. The model finds that the percentage of blacks in the population, university access, the unemployment rate and single female-headed households to …

Online Advertising By The Comparison Challenge Approach, Jae Wong Lee, Jae Kyu Lee

Research Collection School Of Computing and Information Systems

To enhance the effectiveness of online comparisons from a manufacturer's point of view, we develop a framework for the comparison challenge approach. To develop the comparison challenge framework, we analyze 12 factors that determine the characteristics of comparison and propose models of valuable comparison challenges using the CompareMe and CompareThem strategies. We demonstrate the approaches with the example of PC selection. To help plan the comparison challenges, we formulate a mathematical programming model that maximizes the total value of comparison under the constraints of comparison opportunity and budgetary limitation. The model is applied to eight comparison scenarios, and its performance …

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 …

Service Pattern Discovery Of Web Service Mining In Web Service Registry-Repository, Qianhui Althea Liang, Jen-Yao Chung, Steven M. Miller, Yang Ouyang

Research Collection School Of Computing and Information Systems

This paper presents and elaborates the concept of Web service usage patterns and pattern discovery through service mining. We define three different levels of service usage data: i) user request level, ii) template level and iii) instance level. At each level, we investigate patterns of service usage data and the discovery of these patterns. An algorithm for service pattern discovery at the template level is presented. We show the system architecture of a service-mining enabled service registry repository. Web service patterns, pattern discovery and pattern mining supports the discovery and composition of complex services, which in turn supports the application …

Serviceorientierte Architekturen (SOA) werden gegenwärtig als Ansatz für eine einfachere und flexiblere inner- und zwischenbetriebliche Integration heterogener Anwendungssysteme diskutiert. Dieser Beitrag entwickelt ein SOA-Architekturmodell und untersucht seine Ausprägung in vier Praxisbeispielen. Er identifiziert aus den Fallstudien ausserdem typische Architekturtreiber, Einsatzziele, Nutzenpotenziale und Architekturmassnahmen einer SOA-Umsetzung in der Praxis.

The Epistemic Consumption Object And Postsocial Consumption: Expanding Consumer‐Object Theory In Consumer Research, Detlev Zwick, Nikhilesh Dholakia

College of Business Faculty Publications

We introduce the concept of the epistemic consumption object. Such consumption objects are characterized by two interrelated features. First, epistemic consumption objects reveal themselves progressively through interaction, observation, use, examination, and evaluation. Such layered revelation is accompanied by an increasing rather than a decline of the object’s complexity. Second, such objects demonstrate a propensity to change their “face‐in‐action” vis‐à‐vis consumers through the continuous addition or subtraction of properties. The epistemic consumption object is materially elusive and this lack of ontological stability turns the object into a continuous knowledge project for consumers. Via this ongoing cycle of revelation and discovery, consumers …

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 …

Can Online Reviews Reveal A Product's True Quality? Empirical Findings Analytical Modeling Of Online Word-Of-Mouth Communication, Nan Hu, Paul Pavlou, Jennifer Zhang

Research Collection School Of Computing and Information Systems

As a digital version of word-of-mouth, online review has become a major information source for consumers and has very important implications for a wide range of management activities. While some researchers focus their studies on the impact of online product review on sales, an important assumption remains unexamined, that is, can online product review reveal the true quality of the product? To test the validity of this key assumption, this paper first empirically tests the underlying distribution of online reviews with data from Amazon. The results show that 53% of the products have a bimodal and non-normal distribution. For these …

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 …

Modeling Online Art Auction Dynamics Using Functional Data Analysis, Karempudi Srinivas Reddy, Mayukh Dass

Research Collection Lee Kong Chian School Of Business

In this paper, we examine the price dynamics of on-line art auctions of modern Indian art using functional data analysis. The purpose here is not just to understand what determines the final prices of art objects, but also the price movement during the entire auction. We identify several factors, such as artist characteristics (established or emerging artist; prior sales history), art characteristics (size; painting medium—canvas or paper), competition characteristics (current number of bidders; current number of bids) and auction design characteristics (opening bid; position of the lot in the auction), that explain the dynamics of price movement in an on-line …

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 …

Common Law Property Metaphors On The Internet: The Real Problem With The Doctrine Of Cybertrespass, Shyamkrishna Balganesh

All Faculty Scholarship

The doctrine of cybertrespass represents one of the most recent attempts by courts to apply concepts and principles from the real world to the virtual world of the Internet. A creation of state common law, the doctrine essentially involved extending the tort of trespass to chattels to the electronic world. Consequently, unauthorized electronic interferences are deemed trespassory intrusions and rendered actionable. The present paper aims to undertake a conceptual study of the evolution of the doctrine, examining the doctrinal modifications courts were required to make to mould the doctrine to meet the specificities of cyberspace. It then uses cybertrespass to …
