    An Investigation Report on Auction Mechanism Design

    Full text link
    Auctions are markets with strict regulations governing the information available to traders in the market and the possible actions they can take. Since well designed auctions achieve desirable economic outcomes, they have been widely used in solving real-world optimization problems, and in structuring stock or futures exchanges. Auctions also provide a very valuable testing-ground for economic theory, and they play an important role in computer-based control systems. Auction mechanism design aims to manipulate the rules of an auction in order to achieve specific goals. Economists traditionally use mathematical methods, mainly game theory, to analyze auctions and design new auction forms. However, due to the high complexity of auctions, the mathematical models are typically simplified to obtain results, and this makes it difficult to apply results derived from such models to market environments in the real world. As a result, researchers are turning to empirical approaches. This report aims to survey the theoretical and empirical approaches to designing auction mechanisms and trading strategies with more weights on empirical ones, and build the foundation for further research in the field

    This exposition summarises research published in several academic articles, in order to meet the requirements of PhD by publication. The focus of the work is on the role of electronic procurement in management of the purchasing function. From the late 1990s a number of independent e-procurement mechanisms were launched which offered potential benefits such as increased order accuracy, transaction efficiency and greater integration between trading partners. At the outset of this programme of research, e-procurement was therefore an emerging phenomenon with little academic research and presented an opportunity to investigate a largely unexplored area. Edmondson and McManus (2007) suggest that for nascent, as opposed to mature areas of research, where few formal constructs or measures exist, an exploratory, qualitative approach is required. This research followed such an approach through the use of case studies, involving observation, participation and interviews with key organisational actors. Each paper makes use of several cases in order to compare and contrast results from different organisations and to draw conclusions from multi-case analysis. The published articles focus on the impact of core applications within e-procurement, including online reverse auctions, electronic marketplaces, online catalogue sites, and buying systems covering the ‘requisition to pay’ cycle. The findings from the papers address a number of core themes in purchasing management. In considering buyer-supplier relationships, it was observed that such dyads are driven by traditional buyer negotiation factors such as segmentation, power and price and that use of eprocurement applications tended to enforce such traditional behaviours. In relation to the potential for integration, the study found that integration between firms was barely affected, as the concept of integration was neither an objective nor a business case driver for e-procurement adoption. This situation reflects the finding that procurement managers pursue functional targets rather than supply chain-level objectives. However, other significant effects from e-procurement adoption were noted such as the tendency by buyers to reduce supplier numbers and a move to re-engineer the procurement function in buying firms, through automating transactional processes. The research finds that e-procurement does not have a deterministic impact on purchasing management, and that it acts as an enabler to more effective management of the function though the way its different mechanisms are deployed. The exposition establishes that e-procurement is used in relation to supply conditions which are characterised by both ‘markets’ and ‘hierarchies’, but that it is the predefined purchasing strategy of the firm, rather than available technology solutions, which determines when markets and hierarchies are used. Additionally, an original model is introduced, focusing on developing an e-procurement policy which can support strategic purchasing goals. This model extrapolates findings from stages in the research, and marries together elements from various papers and frameworks therein, to produce some guidelines for adoption of this technology

    Creating business value through e-marketplace trading

    Electronic marketplaces (e-marketplaces) have been researched over many years from the study of electronic data interchange (EDI) systems to the current internet based trading platforms. Early e-marketplaces connected a buyer and supplier using proprietary systems that established a market hierarchy. The buyer was responsible for the system, established the terms of trade and the electronically enabled supplier could connect to the system. These systems were costly to build, which limited their use, and only organisations with an integrated system could use them. The web based e-marketplaces opened up the possibility of connecting many buyers and suppliers and enabling electronic transactions. The e-marketplace offers opportunities for establishing trade relationships with many organisations across the world. Business to business (B2B) e-commerce is a significant part of the Australian economy and there are opportunities to take advantage of e-marketplace trading. One of the advantages of electronic trading is the ability of the technology to deliver transaction benefits; these can have a significant impact on organisations regardless of organisational size. However, despite the potential of the e-marketplace to deliver organisational benefits there have been limited studies which consider the strategic implementation of e-marketplace trading. Organisational strategy and the implementation of strategic initiatives involve interactions between organisational structures and agents. The analytical dualism this represents complicates uncovering the fundamental causes of e-marketplace participation. Not only does the adoption of e-marketplace trading impact on the buyer and supplier organisations, it introduces the e-marketplace vendor organisation and the e-marketplace technology into the participation decision. The complexity of the interactions across organisational structures and between organisational agents and technology adoption can produce a diversity of outcomes. The philosophical underpinning of critical realism for the study is supported by the lack of understanding as to why, and in what circumstances, organisations successfully participate in e-marketplace trading. The critical realist philosophy provides the opportunity to understand the interrelationships between context, organisational structures and agents and identify the causal mechanisms involved in producing various outcomes. It allows for the development of middle level theory as existing theories are examined to explain the perceived phenomena. Large organisations operating in Western Australia are used as case studies to uncover the causal relationships between context, structures and agents that can produce successful, strategic implementation of e-marketplace participation. Existing literature in relation to e-marketplaces and IT adoption is used to develop the research questions and formulate the interview questions. The structured case methodology is used to analyse each case and relate the findings to possible explanatory theories. Context, mechanism and outcome patterns, identified in each case, are presented. Building on economic market, institutional and network theories the research identifies organising vision theory and community discourse as explanations for organisational legitimation that can circumscribe the use of e-marketplace trading. Six types of community group that influence organisational adoption of e-marketplace technology are identified. The research suggests that the influence of these groups within the organisation, the fit with organisational culture and strategic objectives can prevent or instigate change. Further, the decision making process supported by the group (or group member) is more influential in the strategic adoption of the e-marketplace than the ability of the technology to deliver efficiency or transaction processing gains. This implies that technology adoption studies should include contextual and environmental issues and practitioners should examine how much their decision making is influenced by organisational and environmental features. The thesis contributes to the discussion on organising vision theory, e-marketplace trading and business value creation. It demonstrates the application of the structured case study methodology to research that is underpinned by critical realism

    Revisiting the IT Productivity Paradox: A Technology Life Cycle Perspective

    In this paper, we revisit the “IT Productivity Paradox,” which refers to the inconclusive relationship between IT investment and performance improvement found in empirical studies. We argue that the cause of the “IT Productivity Paradox” is more than empirical measurement difficulties. Based on a rather comprehensive review of the literature, we identified and contrasted three underlying theoretical perspectives of the empirical studies. We then propose a new theoretical framework toward an in-depth theoretical understanding of the paradox. Developed upon the contingency approach, the proposed framework considers the stages of technology life cycle. The framework not only can provide useful guidance for practicing managers but also potentially can resolve the “IT Productivity Paradox,” hence making a significant contribution to the literature

    A simulation based supply partner selection decision support tool for service provision in Dell.

    Partner selection is an important aspect of all outsourcing processes. Traditional partner selection, typically involves steps to determine the criteria for outsourcing, followed by a qualification of potential suppliers and concluding with a final selection of partner(s). Reverse auctions (RAs) have widely been used for partner selection in recent times. However, RAs, although proven successful in initial price reduction strategies for product and service provision, can suffer from reduced effectiveness as the number of executions increases. This paper illustrates Dell’s experience of such diminishing returns for its outsourced after sales product repair service and presents the development, of a new partner selection methodology which incorporates a new process improvement stage to be executed in combination with the final selection phase. This new methodology is underpinned by the development of a computer based simulation supply partner selection decision support tool for service provision. The paper highlights the significant additional cost saving benefits achievable and improvement in service through the use of advanced simulation based decision supports

    Pricing the Cloud: An Auction Approach

    Get PDF
    Cloud computing has changed the processing and service modes of information communication technology and has affected the transformation, upgrading and innovation of the IT-related industry systems. The rapid development of cloud computing in business practice has spawned a whole new field of interdisciplinary, providing opportunities and challenges for business management research. One of the critical factors impacting cloud computing is how to price cloud services. An appropriate pricing strategy has important practical means to stakeholders, especially to providers and customers. This study addressed and discussed research findings on cloud computing pricing strategies, such as fixed pricing, bidding pricing, and dynamic pricing. Another key factor for cloud computing is Quality of Service (QoS), such as availability, reliability, latency, security, throughput, capacity, scalability, elasticity, etc. Cloud providers seek to improve QoS to attract more potential customers; while, customers intend to find QoS matching services that do not exceed their budget constraints. Based on the existing study, a hybrid QoS-based pricing mechanism, which consists of subscription and dynamic auction design, is proposed and illustrated to cloud services. The results indicate that our hybrid pricing mechanism has potential to better allocate available cloud resources, aiming at increasing revenues for providers and reducing expenses for customers in practice
