What is an auction called that is conducted with no reserve?

An auction conducted with no reserve is referred to as an absolute auction. In this type of auction, the item being sold will go to the highest bidder regardless of the final bid amount. This encourages competitive bidding, as bidders know that the item will be sold without a minimum price requirement, which can create excitement and urgency during the auction process.

Absolute auctions are often used for quick sales, allowing sellers to attract a larger audience and generate higher bids due to the lack of a reserve price. This can lead to favorable outcomes for sellers who wish to liquidate assets quickly. The transparency of the auction's rules can also enhance bidder confidence, as they know the auction will not end without the item being sold.

In contrast, other auction types may involve minimum bids or conditions that must be met before the sale is finalized, which can deter some bidders and may not create the same level of competitive bidding environment as an absolute auction does.
