The Revenue Equivalence theorem states that under the benchmark model, all the four basic auction for- mats yield the same average revenue to the seller.
What are the revenue equivalence theorems in bidding theory?
Revenue equivalence theorems in bidding theory establish conditions under which the expected revenue from various auction types (e.g., standard sealed bidding sales and progressive oral auctions) is the same. (2013) Revenue Equivalence Theorem. In: Gass S.I., Fu M.C. (eds) Encyclopedia of Operations Research and Management Science.
What is an example of revenue equivalence?
In fact, we can use revenue equivalence to prove that many types of auctions are revenue equivalent. For example, the first price auction, second price auction, and the all pay auction are all revenue equivalent when the bidders are symmetric (that is, their valuations are independent and identically distributed).
When does the revenue equivalence theorem break?
The revenue-equivalence theorem breaks in some important cases: : 238–239 When the players are risk-averse rather than risk-neutral as assumed above. In this case, it is known that first-price auctions generate more revenue than second-price auctions.
Is revenue equivalence true for sealed-bid auctions?
Indeed, the expected payment for each player is the same in both auctions, and the auctioneer’s revenue is the same; see the page on first-price sealed-bid auction for details. In fact, we can use revenue equivalence to prove that many types of auctions are revenue equivalent.
Do all auctions have the same expected revenue?
We have shown intuitively that in a first-price auction, essentially, the buyer with the highest valuation will optimally bid his estimate of the 2nd-highest valuation. Therefore, all four standard auc- tion formats raise the same expected revenue.
How do you find the expected revenue for a second-price auction?

Is third price auction truthful?
Third price auction: in third price auction, the item is allocated to the highest bidder who is then charged third highest bid (it is left to the reader as an exercise to prove that such auction is not truthful). Although this auction is not used in practice, it is an interesting exercise to study it.
What is truthful bidding?
By utilizing the second-price mechanism in a Vickrey auction, individuals bid truthfully – individuals are motivated to bid their maximum value because the individual understands that if their bid wins, they will only need to pay the second-highest bid value.
How do you calculate expected revenue?
A simple way to solve for revenue is by multiplying the number of sales and the sales price or average service price (Revenue = Sales x Average Price of Service or Sales Price). With that being said, not all revenues are equal.
What is revenue auction?
Revenue equivalence is a concept in auction theory that states that given certain conditions, any mechanism that results in the same outcomes (i.e. allocates items to the same bidders) also has the same expected revenue.
Is bidding truthfully a Nash equilibrium?
Recall that in the case of the first-price auction truthful bidding is a Nash equilibrium iff for the considered sequence of valuations the auction coincides with the second-price auction. Now truthful bidding, so v, is always a Nash equilibrium.
How do you bid at a second price at an auction?
Bidding your true value is the dominant strategy in second price auctions. Any deviation from the true value would not increase the bidder’s payoff. In the case that the second highest bidder has the choice of increasing their bid and they decide to do so, their new bid would surpass their initial bid.
Is auction theory a game theory?
A game-theoretic auction model is a mathematical game represented by a set of players, a set of actions (strategies) available to each player, and a payoff vector corresponding to each combination of strategies. Generally, the players are the buyer(s) and the seller(s).
What is the best auction type?
Absolute Auction means highest bid wins, regardless of price. The typical result? More money for the seller because of the competitive nature of bidding. Competition typically heats up most intensely at Absolute Auctions because bidders know that by besting a rival across the room or online, the property can be theirs.
What is a reverse tender?
Under a tender or reverse auction program, a government or utility designs a process to select bids and procure electricity to meet specified capacity goals.
Why are second price auctions better?
Not only do second price auctions prevent advertisers from overpaying for ad inventory, but it also allows them to analyze the competition to optimize any future bids for the same publisher’s ad inventory.
What is the third price?
Third-degree price discrimination occurs when a company charges a different price to different consumer groups. For example, a theater may divide moviegoers into seniors, adults, and children, each paying a different price when seeing the same movie. This discrimination is the most common.
What is second price sealed bid auction?
Abstract. A second-price sealed-bid auction is that a bidder who offers the highest price gets a good in the second highest price. This style of auction solves the problems of both an English auction and a first-price sealed-bid auction.
