This Thesis will begin by highlighting the significance of social media networks and e-Commerce in today’s business environment. The purpose of this paper is to develop an external marketing strategy that can be employed by start-up firms operating in the e-Commerce of reverse auction sites.   The paper will particularly focus on the company EarnBidWin.com and the marketing strategy will be based on the Service Perspective. EarnBidWin.com is an online reverse auction site that is new and unique compared to other existing models of reverse auction. EarnBidWin.com is a web-based advertising and networking platform that features e-Campaigns (performance-based advertising) and reverse auctions. EarnBidWin.com’s unique business model within a social-business network offers a win-win situation for all parties concerned.   A qualitative research method is conducted by using a case study. The data is gathered through the primary source of interviews with the CEO of the company, along with the secondary source of extensive academic literature. Finally, the results are presented in a discussion of a proposed marketing strategy based on the combination of the Service Perspective and the Critical Success Factors of high growth start-up firms in the e-Commerce arena.

By exploring a multitude of auction types and designs that have been or are currently being used in the private sector, these practices set a basis for researching the auction types being used in the public sector. This paper further explores the regulations guiding the use of e-RAs and investigates the federal government's application of reverse auctions through studies, reports, and interviews with users of e-RAs. Details as to what attributes are prevalent in these e-RAs, what features are best suited for e-RAs, and what benefits have been derived from the use of e-RAs in the federal government are also included. Finally, the researchers found that e-RAs have increased transparency, cost savings, and efficiencies in the acquisition process. Although reverse auctions are being used effectively, the researchers found that there are still opportunities for improvement including incorporating a fully functional best-value tool into e-RA technology and developing more thorough federal guidance on e-RAs as an alternative pricing method.

Industrial online-reverse-auctions have become a common procurement strategy used by many firms to reduce the cost of purchased goods and services. The advantages of online-reverse-auctions include significant price reductions, increased purchasing and selling efficiencies, and access to new supply and purchasing markets. Despite these benefits, practitioners and academics alike have raised concerns with respect to the impact of online-reverse-auctions on the buyer-supplier relationship. Previous research suggests that the parameters and characteristics of an online-reverse-auction can influence the perceptions of online-reverse-auction participants. This dissertation investigates this phenomenon by examining how the design of an online-reverse-auction influences the supplier's perception of the buyer-supplier relationship. Specifically, this research considers the effects of online-reverse-auction design in terms of the independent variables of auction control, auction bid visibility, and auction award rules and the dependent variables of supplier commitment to the buyer and supplier trust in the buyer. Using a 2 x 2 x 2 quasi-experimental design and the statistical technique of MANCOVA, this study tests hypotheses related to how different online-reverse-auction design characteristics influence supplier commitment to the buyer and supplier trust in the buyer. The results of the study suggest that the type of online-reverse-auctions buyers utilize can have an impact on supplier perceptions of the buyer supplier relationship. Overall, the result suggest that supplier trust is influenced by the type of auction design buyers utilize, however, supplier commitment is not. Auctions utilizing third party auction providers, partial bid visibility, and post auction negotiations tended to result in higher levels of trust on the part of suppliers. This study makes a contribution to the literature in the following areas. First, this study is one of only a handful of empirical studies examining the effects of online-reverse-auction designs on the buyer-supplier relationship. While a considerable debate exists within the literature concerning the pros and cons of online-reverse-auctions, little empirical work exists. This study makes a contribution by providing insight with respect to how online-reverse-auction designs influence supplier perceptions of the buyer-supplier relationships. Secondly, this analysis considers the buyer-supplier relationship in terms of commitment and trust. Previous studies have largely neglected these constructs despite their prominence in the buyer-supplier relationship literature. Finally, given that the use of online-reverse-auctions seems well entrenched in the purchasing strategies of many buying organizations; this study provides guidance for the design of online-reverse-auctions such that buyers can potentially reduce the negative aspects of the process.

No / This chapter examines the role of business-to-business electronic reverse auctions (eRAs), one tool in the armoury of e-purchasing used by businesses including retailers. It tracks the development of this particular technology through the hype cycle and presents some propositions to maximise the use of eRAs as an effective e-purchasing tool. It also explains the damaging effect of the early negative perceptions and underlines the difficulty in overcoming them.

While there is an ever increasing adoption of e-sourcing, where a buyer auctions off procurement contracts to a small group of pre-qualified suppliers, there is a lack of understanding of the impact of dynamic bidding process on procurement outcomes and bidding behavior. To extend the knowledge of this important issue, in this thesis, we explore empirically the value of online procurement auction on cost reduction, quality management, and winner selection from the buyer's perspective. We also explore how incumbent status affects the procurement outcomes. From suppliers' perspective, we characterize their bidding behavior and examine the effect of incumbent status on bidding. First, we collect detailed auction and contract awarding data for manufacturing goods during 2002-2004 from a large buyer in the high-tech industry. The rich data set enables us to apply statistical model based cluster technique to uncover heterogeneous bidding behavior of industry participants. The distribution of the bidding patterns varies between incumbent and non-incumbent suppliers. We also find that the buyer bias towards the incumbent suppliers by awarding them procurement contracts more often and with a price premium. Next, focusing on recurring auctions, we find that suppliers bid adaptively. The adaptive bidding is affected by the rank of suppliers' final bids. Finally, with field data of procurement auction for legal services, we demonstrate that service prices are on average reduced after dynamic bidding events. Most interestingly, the cost savings are achieved without the sacrifice of quality. Incumbent winners' quality is higher, on average, than the quality of buyer's supplier base before the auctions, while non-incumbent winner's quality is lower. These findings imply that the main value of online procurement auctions for business services comes from incumbents in the form of reduced price and enhanced quality. We find that after adjusting for incumbents' higher quality, incumbent bias disappears. Our results also imply that the buyer might possess important information about the incumbents, through past experiences, that cannot be easily included in the buyer's scoring function due to uncodifiability.

There have been significant advances in the information systems (IS) literature about the business value that can be realized through information technology (IT) investments and the mechanisms through which IT creates different facets of business value. We identify three important gaps in understanding the literature on IT business value. First, it is unclear how risk arising from deficiencies in a firm’s information environment, along with internal and external contextual factors, affects a firm’s IT implementation choices. Second, it is unclear how IT resources in a focal domain need to be combined with knowledge resources in the same domain and IT resources in other domains to develop process capabilities and create process-level benefits. Third, it is unclear what risks IT-enabled process innovations create for different process stakeholders and what controls can be applied to mitigate these risks. My dissertation addresses the above three gaps in three essays. The first essay examines the influence of a firm’s information risk on its prioritization of accounting enterprise systems (AES) relative to complementary enterprise systems and the moderation of this relationship by the weaknesses of internal controls and environmental uncertainty characteristics. The second essay focuses on the impact of AES implementation on a firm’s internal controls process, and the complementary roles of managerial competence and enterprise systems implemented in other domains related to the internal controls process of the firm. The final essay explores the risk factors that can arise for buyers and suppliers due to the use of reverse auctions, and the controls that can be applied to mitigate the key risk factors. In terms of research methods, the first two essays apply econometric analysis to panel datasets constructed from multiple sources and the third essay uses a combination of Delphi studies and semi-structured interviews. Collectively, the essays advance our understanding of (1) the factors underlying a firm’s prioritization of IT investment choices; (2) the mechanisms through which IT resources, in combination with human expertise, create business value; and (3) the risks introduced for different stakeholders by the adoption of IT-enabled process innovations and the controls that can be used to effectively mitigate them.

Approved for public release, distribution is unlimited / This thesis investigates the effect that acquisition reform has had on small business participation in the Federal contracting arena. As a result of the transformation of the Federal acquisition process through acquisition reform legislation and the reduction in the acquisition workforce, small business contractors are faced with new challenges to compete for and win Federal contracts. This paper concentrates on examining contract bundling, reverse auctions, electronic commerce and multiple award schedules. It concludes that contract bundling has had a negative effect on small businesses by excluding them from many competitions. It also finds that electronic commerce has had a positive effect on small businesses by giving them greater access to Federal contract opportunities and by speeding up the acquisition process. Regarding multiple award schedules, the research supports benefits for small businesses when they are given the chance to compete through multiple award schedules. It also finds negative implications for small businesses in that multiple award schedules often favor large established businesses at the expense of small businesses. The paper finds a lack of awareness on the part of small business concerning reverse auctions and finds no major impact on small businesses resulting from reverse auctions. / Civilian, Department of the Army PEO-EIS

Participatory Sensing (PS) systems rely on the willingness of mobile users to participate in the collection and reporting of data using a variety of sensors either embedded or integrated in their cellular phones. Users agree to use their cellular phone resources to sense and transmit the data of interest because these data will be used to address a collective problem that otherwise would be very difficult to assess and solve. However, this new data collection paradigm has not been very successful yet mainly because of the lack of incentives for participation and privacy concerns. Without adequate incentive and privacy guaranteeing mechanisms most users will not be willing to participate. This thesis concentrates on incentive mechanisms for user participation in PS system. Although several schemes have been proposed thus far, none has used location information and imposed budget and coverage constraints, which will make the scheme more realistic and efficient. A recurrent reverse auction incentive mechanism with a greedy algorithm that selects a representative subset of the users according to their location given a fixed budget is proposed. Compared to existing mechanisms, GIA (i.e., Greedy Incentive Algorithm) improves the area covered by more than 60 percent acquiring a more representative set of samples after every round, i.e., reduces the collection of unnecessary (redundant) data, while maintaining the same number of active users in the system and spending the same budget.

The research was based on the premise that contracting lowest price bidders can stimulate a dip in prices offered by other bidders, leading to contracts with extremely low values that negatively affect the performance of services. Such contracts may be rife with problems and reduce the overall life span of continuous contracts. These apparent savings, a result of intense competition characteristic to the bidding manner of reverse auctions, should be questioned. The results of this study confirm this premise, showing that 55% of contracts generated through the electronic bidding system have serious issues, and 31% of these contracts resulted in a unilateral termination for breach of contractual terms. An inverse relationship between the initial savings generated in the bidding and contract expiration time was identified - the greater the difference between the estimated value and that which was negotiated during the bidding process, the shorter the duration of the contract. Therefore, hiring well below the market price generates contracts with short lifespans and many problems. Data analyses indicate a need to relativize the adoption of the reverse auction bidding system and reconsider its implications for continuous, effective services. / O presente trabalho investiga os impactos das licitações do tipo menor preço, realizadas por meio de Pregão eletrônico, no desempenho das execuções dos contratos contínuos, efetivados pela Superintendência de Administração da AGU em Pernambuco - SAD/PE -, no período de 2006 a 2010. Teve como proposição a premissa de que a contratação do tipo menor preço pode, em função de suas próprias características, estimular uma redução excessiva nos preços ofertados pelos licitantes e originar contratações com valores muito baixos que interferem de forma negativa no desempenho da prestação dos serviços, gerando infrações contratuais e diminuindo a vida útil dos contratos contínuos. A aparente economia, consequência da acirrada competição nos leilões invertidos, que caracterizam a modalidade licitatória Pregão, em médio e longo prazo, pode ser questionada. Os resultados confirmaram a proposição, evidenciando um percentual de 55% dos contratos, oriundos de Pregão eletrônico, com infrações e 31%, rescindidos unilateralmente por descumprimento de cláusulas contratuais. Foi identificada uma relação, de força moderada, inversamente proporcional entre a economia inicial gerada na licitação e o tempo de execução dos contratos, sugerindo uma tendência no sentido de que - quanto maior a diferença entre o valor referencia e o contratado na licitação, menor o tempo de execução do contrato, pois, parte das contratações muito abaixo do preço de mercado, geraram contratos com pequena vida útil e com muitas infrações. As análises dos dados apontam para a necessidade de se relativizar a adoção da modalidade licitatória Pregão, repensando-se a sua indicação para serviços continuados
