We consider the bilateral trade problem, in which two agents trade a single indivisible item. It is known that the only dominant-strategy truthful mechanism is the fixed-price mechanism: given commonly known distributions of the buyer's valueBand the seller's valueS, a pricepis offered to both agents and trade occurs ifS≤p≤B. The objective is to maximize either expected welfare or expected gains from trade .We improve the approximation ratios for several welfare maximization variants of this problem. When the agents' distributions are identical, we show that the optimal approximation ratio for welfare is . With just one prior sample from the common distribution, we show that a 3/4-approximation to welfare is achievable. When agents' distributions are not required to be identical, we show that a previously best-known (1–1/e)-approximation can be strictly improved, but 1–1/eis optimal if only the seller's distribution is known.
