fin.auctions-winner-curse Calculator
Calculates the winner's curse adjusted bid for a common-value auction, applying a discount below the naive expected value. In common-value auctions (oil leases, M&A), the winner systematically overpays because the highest bidder has the most optimistic estimate — the adjustment corrects this bias.
