Laudon and Traver (2017) describe online auctions as one of the formats that defined early e-commerce, with eBay turning millions of people into sellers. Yet today most online purchases, even on eBay, happen at fixed prices. Why did the auction fade? I want to argue that buyers came to value convenience more than the chance of a bargain, and that auctions survived only where uncertainty about value makes bidding useful.

Einav et al. (2018) studied this shift directly. Using eBay data, they compared items sold both by auction and at posted prices and examined why the share of auctions fell over the 2000s. They concluded that the main driver was a change in demand: buyers became less willing to wait for an auction to end and to risk losing, and more willing to pay a little more to buy immediately. At the same time, the price discount buyers could expect from auctions narrowed. An auction asks the buyer to spend time and accept uncertainty, and as online shopping became routine, fewer buyers wanted to pay that price for a bargain.

Auctions still make sense where the seller does not know what an item is worth: rare collectibles, vintage goods, unusual cars. Bidding reveals what buyers will pay. For ordinary goods with known prices, a posted price is faster for everyone.

What did not change is the need for trust. Whether a buyer bids or clicks "buy it now," the marketplace works only if strangers can trust each other. Resnick et al. (2006) found that buyers paid about 8 percent more to a seller with an established positive reputation than to a new seller offering matched items. That finding connects this chapter to the course's earlier discussions of trust and business models: a marketplace's real product is the confidence it creates between people who will never meet. The auction was one way to set prices; reputation is what made the marketplace possible, and it remains essential whatever pricing format wins.

For sellers, the lesson is practical. A seller with common items should use a fixed price and compete on reputation, photos and shipping speed, while a seller with a rare item may still do better letting buyers bid. Matching the format to the item, and building a record of good transactions in either case, is what the research recommends.

Natalie, your thread on social commerce, buying directly inside apps where people follow friends and creators, was a great choice for this chapter. I would extend it with the trust idea from my thread. Social commerce works partly because discovery comes from people the buyer already follows, which borrows trust from a relationship. That is powerful, but it also creates risks: a creator may promote products without disclosing payment, and counterfeit or low-quality sellers can reach buyers through ads that look like friends' posts. The marketplaces that lasted, like eBay, built reputation systems and payment protections so buyers did not have to rely on personal trust alone. I think social commerce will need the same tools, such as verified seller ratings and clear disclosure of sponsorships, to keep growing. Returns are another piece. Social platforms that make it easy to return an item bought from a creator's post will earn more repeat buyers than those that leave the buyer to deal with an unknown seller, because the risk of a bad purchase falls on the platform rather than the customer. Clear return rules also make customers more willing to try new sellers. Did the platform in your example offer buyers any protection if a product did not match its description?

Ryan, you argued that portals are dead because people now go straight to apps instead of starting at a home page, and for general portals I think you are right. I would qualify the claim, though. The textbook describes portals as gateways that aggregate content and services, and that function has not disappeared; it has moved. Search engines, app stores and the home screens of smart speakers now play the gateway role, deciding what people see first. Vertical portals, which focus on one industry or interest, also remain strong, such as sites that gather travel options or job listings in one place. So the portal as a home page faded, but the business model of controlling the first stop in a user's path online is alive and very profitable. Advertising is how the modern gateways earn money, just as the old portals did, so the textbook's description of portal revenue models still applies even though the home page has faded. That continuity suggests the concept is worth studying even if the term sounds dated. Studying the gateway role explains much of today's competition among large platforms. The gatekeeper role is, if anything, more valuable now. Would you count a search engine as a portal under the textbook's definition?

Kayla, your example of sneaker resale sites that still use bidding fits the research I cited very well. Einav et al. (2018) found that auctions remain useful where buyers and sellers are uncertain about value, and limited-edition sneakers are a perfect case: the price can change sharply with demand, and no one knows in advance what a rare pair will bring. A bidding system, or a market where buyers post bids and sellers post asking prices, lets the price be discovered instead of guessed. Sneaker platforms have also solved the trust problem in a different way from eBay, by inspecting shoes for authenticity before sending them to buyers, which takes the risk of counterfeits off both parties. That combination, price discovery plus verified quality, explains why resale has become a strong niche for auction-style selling. Fees are a third factor. Resale platforms charge sellers a commission plus processing and shipping costs, and sellers accept them because authenticated listings sell faster and at higher prices than unverified ones, much as the reputation research would predict. Trust, again, is what buyers are really paying for. Authentication turns uncertainty into confidence. Do you think the authentication service or the bidding format matters more to buyers?
