Which of the following are Forward Auction types?

In the context of auction types, a Forward Auction is characterized by the seller listing an item and potential buyers placing bids in order to compete for that item. The Dutch Forward Auction is an example of this type, where the auctioneer starts with a high price that is gradually lowered until a buyer accepts the current price.

In a Dutch auction, the dynamic is such that all bidders are aware of the starting bid, and they have to act quickly as the price decreases. This encourages competitive bidding, allowing buyers to potentially secure items at a lower price if they act before others.

The other terms listed do not fit within the definition of a Forward Auction. Sealed Bid Auctions and Blind Auctions typically involve bidders submitting bids without knowing others' offers, leading to a different bidding strategy than in a Forward Auction. Conversely, a Reverse Auction is used when buyers want to procure a service or item and invite sellers to bid their lowest prices, which directly contrasts with the Forward Auction’s purpose where sellers are seeking to maximize their sale price. Hence, the Dutch Forward Auction firmly represents the Forward Auction types.
