auction models

Auction models are systems used to determine the price of goods or services through competitive bidding. In these models, buyers submit bids indicating how much they're willing to pay. The auction mechanism then decides the final price and winner based on those bids. Different types include English auctions (ascending bids), Dutch auctions (descending bids), and sealed-bid auctions (bids kept confidential). Auction models help allocate resources efficiently, reflect market demand, and can be used in various contexts like art sales, spectrum licenses, and online advertising. They provide a formal framework to facilitate fair and transparent transactions.
