Milgrom and Weber  have shown that the English auction dominates all other auction formats in terms of seller 's expected profit, when the comparison is restricted to symmetric equilibria. Myerson  and Riley and Samuelson  explain that if the buyers are risk neutral and have independently and identically distributed private values, then, for the majority of probability distributions, the seller 's expected profit is maximized making it the optimal bidding strategy. The item is awarded to the buyers with the highest value, and any buyer whose value is lower than an optimally set threshold receives zero expected surplus. These two conditions, however, are satisfied by a large array of trading mechanisms, including each of the standard auctions all with the same seller 's reserve price.
The electronic auction websites have a role of providing the mean to the people who want to sell their electronic devices on the websites in order to get the maximum sale price of the product. The role of these auction sites is to reduce the risk of sellers, protect intellectual property rights, support laws and regulations, provide equal opportunity to the sellers and provide the more enjoyable buying and selling experience to the visitors. There should be proper policies for buying and selling electronic items on the auctions websites (Jacobson, 2003- 2015).

The most important factor for ebay is the speed at which data can be analyzed and recommendations can be made signal a trend before it is over. Ebay estimates that 1,000 new bidders access the online auction site every day, which means 1,000 new opportunities for sellers to market their products.

Ebay, as a company itself, fits more in the category of an oligopoly, which is actually pretty common in any market. Other alternative websites include Yahoo!, Amazon, and Quibids, but there are only a small number of them, certainly not hundreds as in monopolistic competition. Also, eBay is interdependent on the few other auction website companies, competing with the fees they charge, as well as quality of customer support, and buyer/seller reliability. Another characteristic of eBay that coincides with it being considered an oligopoly is the fact that it has numerous entry barriers. It’s such a large company with many restrictions, and it would be hard for an up and coming substitute auction website to break into the market and compete with eBay or the other top companies in the industry.

The company eBay Inc. is an American multinational Internet consumer-to-consumer corporation. Founded in 1995 by Pierre Omidyar in San Jose, California, it is now a multi-billion dollar business with operations localized in over thirty countries including China and India. It’s main enterprise is eBay.com, an online auction and shopping website that allows people and businesses to buy and sell a broad variety of goods and services internationally. Millions of collectibles, décor, appliances, computers, furnishings, equipment, domain names, vehicles, services, intangibles and other miscellaneous items are listed, bought, or sold daily on eBay. Anything can be auctioned on the site as long as it is not illegal and does not violate the eBay’s Prohibited and Restricted Items policy.
The fact that eBay does have some successful competition means that its strategic capability has become less unique. There is a hint in their competitor profile that innovation and perhaps adaptability to different cultures as they innovate is not core to eBay and something which has been developed more successfully by others working within their own national culture. Indeed, eBay rules in its own territory of North America and in Europe. The search capability of eBay also means that niche players do not really make sense, whereas the consumer trust that comes from being a big player is worth everything when trading on-line, as is the notion that whatever you want it will be on eBay because of its size. Thus, the so-called network effects of eBay (the bigger the company, the more successful it will be) and its first mover advantage that has led to this level are key to its success.
