Scenario 1 Length As Neededyou Are Considering Auctioning A Leonard

You are considering auctioning a Leonardo Da Vinci original sketch. There are four bidders with valuations of $3.0 million, $2.2 million, $2.0 million, and $1.5 million. The analysis considers two auction formats: second-price sealed bid auction and first-price sealed bid auction with strategic bid shading. Additionally, the scenario explores how changing valuations to $3.0 million, $2.7 million, $2.0 million, and $1.5 million affects the outcome.

In auction theory, understanding the strategies and outcomes of different auction formats is crucial for maximizing seller profit. This case examines the implications of second-price and first-price sealed bid auctions with particular attention to bidder behavior and valuation influences.

In a second-price sealed bid auction, bidders submit one bid without knowing others’ bids. The highest bidder wins but pays the second-highest bid. Since bidders aim to maximize their payoff, their dominant strategy is to bid their true valuation. Given the bidders’ valuations of $3.0 million, $2.2 million, $2.0 million, and $1.5 million, the highest valuation bidder—valuing at $3.0 million—would win. The price paid would be the second-highest valuation, which is $2.2 million. Hence, the winner is the bidder valuing the sketch at $3.0 million, paying $2.2 million.

In contrast, a first-price sealed bid auction requires bidders to submit bids without revealing their valuation, and the highest bid wins, with the winner paying their bid amount. Strategic bidding involves bid shading—bidders bid less than their true valuation to increase their surplus. If bidders deviate from truth-telling and shade their bid by 20%, each bidder lowers their bid by that percentage, thus bidding at 80% of their valuation.

Calculating the shaded bids:

  • Bidder 1 (valuation $3.0M): bid = 0.8 × 3.0 = $2.4M
  • Bidder 2 (valuation $2.2M): bid = 0.8 × 2.2 = $1.76M
  • Bidder 3 (valuation $2.0M): bid = 0.8 × 2.0 = $1.6M
  • Bidder 4 (valuation $1.5M): bid = 0.8 × 1.5 = $1.2M

Under these strategies, the highest shaded bid is from the bidder with a valuation of $3.0 million at $2.4 million, which exceeds the other bids. Therefore, this bidder wins the auction, paying their bid of $2.4 million. The actual valuation of the winner is $3.0 million, and the price paid is $2.4 million. The bid shading strategy increases the winner’s profit compared to truthful bidding, but it also affects the auction outcome and the seller’s profit.

When the valuations increase to $3.0 million, $2.7 million, $2.0 million, and $1.5 million, the analysis shifts slightly. The highest valuation bidder would bid approximately $2.4 million (80% of $3.0 million), and the second-highest valuation bidder with $2.7 million would bid approximately $2.16 million. The winner would be the bidder with the valuation of $3.0 million, paying $2.4 million. This results in a seller profit of $2.4 million. If the second-highest valuation were $2.7 million, the winner would pay $2.16 million, which is lower, increasing the seller’s profit.

Reviewing these scenarios, the optimal auction for maximizing profit depends on valuation distributions and strategic bid shading. Typically, second-price auctions tend to yield higher expected revenues when bidders bid truthfully. However, in strategic settings, first-price auctions may generate higher revenue because bidders shade their bids intentionally, leading to higher bids than would truthful bidding in equilibrium. Therefore, if the goal is to maximize expected revenue, the second-price auction would be preferable if bidders bid truthfully, but strategic behavior can alter this outcome. In the case of the valuation increase to $3.0 million, $2.7 million, $2.0 million, and $1.5 million, the second-price auction still tends to be more advantageous from a revenue perspective, assuming bidders bid truthfully.
