Internet auctions have become an increasingly common method for exchanging goods and services across the world both among consumers themselves, as well as between businesses and consumers. These Internet auction mechanisms have the scope of incorporating procedures of much greater complexity and variety, and they exhibit characteristics and properties that are quite distinct from conventional auctions. In this paper, the authors provide an experimental study of the performance characteristics and operational behaviour of a number of online auction models, including the fixed time forward auctions, the Vickrey auctions, and models with soft close variable auction times. These online auction models are studied through systematic simulation experiments, based on a series of operational assumptions, which characterize the arrival rate of bids, as well as the distribution from which the private values of buyers are sampled. Suggestions for efficient online auction design and procedures for improving auction performance are given, and the behaviour of the average auction income and average auction duration are quantified and compared.

Genetic Network Programming

Nowadays, Dutch auction is used widely at online auction sites. To make online Dutch auction more efficient and more intelligent, it is useful to develop an agent using evolutionary computation which will be adaptive to different auction environments. In this paper, a Genetic Network Programming (GNP) based strategy for auction agents has been proposed to do auctions in multiple round Dutch Auction environments under two types of auction models, no time limit model and time limit model. GNP is a graph-based evolutionary method extended from Genetic Algorithms (GA) and Genetic Programming (GP), which can create optimal solutions by evolution. Although the application of GNP to English auction has been done already, here, a new GNP structure is used for Dutch auction. The simulation results show that the GNP based strategy can also make the agents work well in Dutch auction and the advanced GNP structure makes the agents perform better than that in English auction.

Theoretical Approaches

Purpose This study aims to explore how a microlending digital platform connects social investors in developed countries and micro-entrepreneurs in Africa. However, additional research is necessary to discuss how online auction models are designed and implemented and how existing theories can explain their use in the so-called developing countries. Design/methodology/approach The research is based on a single case study: an online auction model for microlending named AfricaMC. Two main methods collected empirical data, namely, online participant observation, i.e. real-time participation in the online auction market and in the forum of discussions, where the authors observed the processes of microlending transactions as registered members; analysis of online documents, by reviewing forum discussions, analyzing reports, blogs, chats and other materials. Findings The results suggest that using sociological and information systems theoretical lenses in a complementary manner could provide greater value than using economics. Originality/value The study makes two main contributions. First, it mobilizes a pluralist theoretical approach based on economic, sociological and information systems perspectives to improve the understanding of microlending digital platforms using online auction models. Second, it uses the understanding produced from data analysis of one particular African case to validate propositions derived from these three theoretical approaches that might be applied to other cases.

Definition Of

The Internet is a new medium of communication connecting potential partners in trade worldwide. The initial frenzy over its promises led to grossly exaggerated valuations of business models that were mere transplantations of existing processes to the alternative channel. Now that the bubble has burst, more sensible and critical thoughts can be turned to true transformations that are creating and nurturing markets of the future. Online auction is one of the very few cases that has held a steady course, as evidenced in the success to date of eBay.com. Founded in September 1995, eBay has become a global trading platform with presence in 39 markets where on any given day, there are more than 113 million listings across 50,000 plus categories. In 2009, at least 86 million people will buy and sell well over $2000 worth of goods every second (www. ebay.com). To survey the state of development of online auctions apart from eBay, on a pragmatic rather than theoretical basis, we examine variations in auction mechanisms, and give examples of implementation online at this writing. The commonly used terminology and definition of auction models can be found in e.g. McAfee and McMillan (1987). For conciseness and consistency, the www prefix and .com suffix are omitted from the URL of corresponding companies, and all lowercase is used throughout.

Use Of The Internet

Businesses today must be fast and flexible, responsive to customers, and cost effective in their operations. They must collaborate more frequently with partners to build virtual organizations and supply-chains that reduce times-to-market and costs. E-business is the use of the Internet along with other electronic means and technologies to conduct within-business, business-to-consumer, business-to-business, and business-to-government interactions. A basic model of an e-business is the e-shop model, which is based on providing a self-service storefront to a customer by displaying the company catalogs and product offers on a Web site. An e-procurement model focuses on the buying aspect of the business. A typical architecture for e-procurement consists of a browser-based self-service front-end to the corporate purchasing system or its ERP. The supplier catalogs are presented to end-users through a single unified catalog, thereby facilitating a corporate-wide standard procurement process. Online auction models have also received much attention for automating dynamic trading. Other models are based on creating value-chain businesses, such as service provisioning of specific functions for the value-chain, and electronic payments or logistics.
