Here’s a concise overview of each concept, including their definitions and key characteristics:

1. Auctions

Definition: An auction is a competitive process in which goods or services are sold to the highest bidder. Auctions can be conducted in various formats, both online and in-person.

Key Characteristics:

• Bidding Process: Participants place bids on items, and the auction concludes when the time expires or no higher bids are placed.
• Types of Auctions:
  • English Auction: Bidders openly bid against one another, with each bid being higher than the previous one.
  • Dutch Auction: The auctioneer starts with a high price that is lowered until someone accepts the current price.
  • Sealed-Bid Auction: Bidders submit secret bids, and the highest bid wins.
• Buyers and Sellers: Auctions connect sellers looking to maximize the price of their items with buyers seeking specific goods.

Examples:

• eBay is a prominent online auction platform where users can bid on a variety of items.

2. Web Portals
