What is the Nash equilibrium in a first-price auction?
First-Price Auction Suppose all bidders follow a strategy s(vi), with s monotonically increasing in vi. Then, s : vi → Bi. It can be shown that a Nash equilibrium in this case is s(vi) = M(vi) < vi. Thus, in a first-price auction, all bidders bid less than their true value.

FPSBA are thought to lead to low procurement costs through competition and low corruption through increased transparency, even though they may entail a higher ex-post extra cost of the completed project and extra time to complete it.
