As plataformas de e-marketplace (EM) atuam como um ponto de encontro virtual, onde vendedores e compradores encontram-se e eventualmente fecham negócios. Em um EM, diversos vendedores competem entre si anunciando ao mesmo tempo produtos exatamente iguais por preços possivelmente diferentes. No entanto, não necessariamente o anúncio mais barato é o que realiza a venda. Dado que nos anúncios publicados nestas plataformas há um grande conjunto de elementos sob responsabilidade do operador do EM, iguais entre todos os anúncios, este trabalho busca colaborar com a compreensão dos fatores controláveis pelo vendedor que influenciam na geração de preço-prêmio em e-marketplaces. A partir da revisão de pesquisas anteriores sobre o tema, foi elaborado um modelo que considera que a geração do preço-prêmio é influenciada pelas características do vendedor (reputação, porte e localização), do anúncio (utilização de recursos multimídia, divulgação, opções de pagamento e entrega, serviço e histórico do anúncio) e do produto (condição e tipo). Para validar este modelo, foi desenvolvido um programa que ao longo de 56 dias coletou dados reais de vendas de três produtos diferentes (celulares iPhone, videogames Playstation 4 e tênis femininos da marca Osklen) no maior e-marketplace deste tipo no Brasil. Estes dados analisados e utilizados para a verificação de nove hipóteses. A reputação que o vendedor construiu ao longo das vendas anteriores mostrou-se como um importante fator de influencia. Vendedores com boa reputação conseguem vender com preços maiores, assim como vendedores com pior reputação são penalizados nos valores de suas vendas. O porte dos vendedores influencia positivamente até certo ponto. Existem vendedores de grande porte que, possivelmente se beneficiando dos ganhos de escala, praticam preços menores. A localização do vendedor é relevante no preço da venda e esta relevância varia de acordo com o produto. Também há diferença na influência de acordo com o produto para a utilização de recursos multimídia e para o envio da nota fiscal junto ao produto. Pagar por um pouco mais de exposição que os padrão oferecido pela plataforma gratuitamente permitiu a realização de vendas com preços maiores, mas o efeito oposto foi observado quando pagou-se pela máxima exposição possível. Também venderam por valores mais altos os anúncios mais antigos e os que ofereceram frete gratuito. / E-Marketplace (EM) platforms are virtual meeting points where sellers and buyers can meet and eventually close a deal. In an EM, various sellers compete against each other offering similar products with different prices. The cheapest offer is not necessarily the one that make the sale. As listings published in an EM have a great number of elements controlled by the platform operator, hence equal to all listings. This work aims to understand the factors controllable by the seller that can influence premium price generation in EMs. Based on the existing literature a model is proposed, in which premium price is influenced by seller characteristics (reputation, size and location), listing characteristics (multimedia resources, exposure, payment and shipping methods, service and ad history) and product (item condition and type). To validate this model a software was developed to collect real data from the largest retail EM in Brazil. During 56 days sales of three products (iPhone smartphones, Playstation 4 videogame consoles and Osklen female tennis shoes) were watched and stored in a database. This data was analyzed and used for verification of nine hypotheses. Reputation acquired by a seller with his previous sales was found as an important element influencing the sale price. Sellers with good reputation were able to sell its items by a higher price and sellers with bad reputation had to sell it cheaper. Seller size exerted positive influence to some extent. Big retailers selling in the EM may be able to sell for a smaller price and make profit thanks to the economies of scale. Seller localization is also relevant. The intensity of this relevance varies by product. It was also noticed difference according to the product for the use of multimedia resources and to if the seller says it will provide a tax invoice attached for the sale. Paying to the EM operator for some additional exposure also made it possible for the seller to achieve prices, but the effect was the opposite when the seller paid for the maximum exposure possible. Old listings and listings that offered free shipping also reached higher prices.

The World Health Organization (WHO) has been implementing the Healthy Marketplace initiative in the market setting of developing countries since 1997. This initiative forms part of the Healthy Cities strategy and is reinforced through the Ottawa Charter for Health Promotion. The WHO Food Safety Division has indicated that every city in the WHO Healthy City program will eventually also have a Healthy Marketplace program. This is despite the absence of any published guidelines for facilitating program implementation, a clearly articulated Healthy Marketplace concept, and a dearth of meaningful program evaluations. This thesis set out to explore the views and experiences of in-country stakeholders involved in a Vietnamese Healthy Marketplace program. It also set out to examine the roles and perceptions of experts engaged in the design and delivery of programs across the developing world. Through an iterative and post-positivist research methodology, this inquiry collected and analysed data from five key sources: documents, detailed questionnaires, semi-structured interviews, and observations and reflections. The findings revealed that various and even conflicting program concepts and aims existed across and within groups, having significant implications for practice. The settings approach was not the dominant approach to health promotion in the Vietnamese market, but rather a 'top-down' topic-based approach dominated as the mechanism for program delivery. Consequently, numerous challenges have been identified for Healthy Marketplace policy and practice. The challenges are prefaced on the adoption of a settings approach, and include the need for : market communities to set their own agendas; the program target audience to be redefined; increased power sharing across stakeholders; the re-education of professionals; the sharing of knowledge; and the adequate resourcing of Healthy Marketplace programs / Master of Science (Hons)

Para a realização deste trabalho foram realizadas pesquisa exploratória e pesquisa aplicada a partir do ambiente do Elo7, maior marketplace brasileiro de produtos artesanais e autorais. Vinte empreendedores que comercializam seus produtos na plataforma responderam questionário com dez perguntas sobre o tema. Foi constatado que eles aumentaram suas vendas ao aderirem à  plataforma e os benefícios não são advindos pelo tráfego de clientes, mas também pelos custos mais baixos dos serviços oferecidos e pela credibilidade do site.

The beauty of group-buying is that the price will go down as the value of accumulated orders is increasing. However, the beauty cannot be realized if many customers are waiting have a lower price. Therefore, it may affect the performance of the group-buying. How to design different incentives to induce customers to join the group-buying as early as possible is the purpose of this study. In the light of inducing buyers to join the group-buying as early as possible, three incentive mechanisms, time-based, quantity-based, and sequence-based, are proposed. In order to verify the performance of the three proposed new group-buying models compared with that of the traditional group-buying model, an experiment was implemented. According to the results of the experiment, we found that the time-based model can reduce customers¡¦ decision time before joining the group-buying. While the sequence-based model also can push customers to join the group-buying in the very beginning. As for the quantity-based model, it is in our expectation that the customers buy more than their original plan in order to get more discounts. We also observe that buyers' satisfaction is higher if the group-buying model can effectively reduce the price. Furthermore, the earlier customers join the group-buying, more satisfactions they will get. Besides, the buyers also agree with that the group-buying model can effectively reduce the price. Furthermore, we discover that the perceived value, perceived usefulness, and perceived easy of use can positively affect the buyers' attitude, and consequently, buyers are willing to join the group-buying in the future.

Abstract E-Marketplace is a major model for B2B commerce. The thesis uses the transaction cost theory to investigate factors affecting the intention of adopting e-marketplace for Taiwanese petrochemical companies, Factors under study include characteristics of petrochemical products, the readiness of computerization in business, and attitude toward adopting e-marketplace. The results indicate that larger companies have stronger intentions than smaller ones to adopt an e-marketplace. Companies having a great demand on digitizing their procurement procedures are more willing to reduce their transaction costs through e-marketplaces. Businesses with higher degree of computerized operations require more functions in the e-marketplace. In addition, security over the Internet and the degree of collaboration among partners are also key factors. With regard to choosing a marketplace, most local petrochemical companies prefer joining the e-Marketplace, managed by large suppliers of raw materials. Based on the above observations, Chinese Petroleum Corporation, may be the largest upstream company producing petrochemical raw materials in Taiwan, may be the most suitable for offering such an e-marketplace to facilitate collaboration and alliance among companies. This also provides a means for globalization in the future.

The dissertation focuses on the shaping of merchants’ subjectivity in Karachi’s contemporary marketplace. It does this by placing human experience within the matrix of the cosmological value system, driven to a large extent by Islamic moral and ethical principles, as well as everyday material conditions, determined by economic activity. In doing so, it brings together the material and spiritual in conversation with each other. This dissertation particularly focuses on the convergence of Sufi moral discourse and meditative practices of zikr/dhikr with globalized technologies of finance capitalism. It seeks to answer: How do the two seemingly different practices converge? Modern financial practices aim to discipline merchants into becoming economic subjects accumulating capital. In contrast, the spiritual tradition of Sufi techniques shapes this excessive desire for accumulating, through the meditation (zikr/dhikr), molding the merchants into charitable subjects. Being a self-maximizing as well as a self-annihilating individual in the market, the merchant is able to contain the larger structuring of money and moral universes in everyday life. The experience generated at the threshold of accumulation and charity, I argue, gives rise to an affirmative subjectivity, which perceives the unity of existence the way it is. / text

The Internet has successfully served the world for more than three decades, while limitations and drawbacks still exist. A lot of researches have been done on innovation of Internet to address those inadequacies. One approach to improve Internet performance is to make choice as a principle in network architecture. We believe that a service-based network architecture with choice, or we call it ChoiceNet, is the most suitable option for future Internet. In this thesis, we design and implement a network service marketplace. Due to the flexibility and functionality of web application, the marketplace is implemented by a web application to fulfill functions such as storing and searching network services, handling actual financial transaction and interacting with client and service planner.

Data ownership is of fundamental importance in the digital economy of today. Commercializing academic research, whilst maintaining ownership of it, is a task that can now be accomplished due to the strengths of blockchain technology, which allows data to be registered, made unique, and traced to its origins. We propose a blockchain use-case for licencing academic research, based off an academic project named UniCoin. In this thesis, we discuss how to fairly attribute credit between all sources of knowledge that contribute to new pieces of academic research, using citation network analysis and centrality measures. Katz centrality, in-degree centrality, and PageRank are three potentially useful centrality measures, with varying results: these are compared using case studies based on three papers co-authored by Andrei Shleifer. We use these centrality measures to guide how to fairly attribute credit, and thus how to distribute licencing revenues generated through UniCoin.
