2025 Gains-from-Trade in Bilateral Trade with a Broker
abstract
We study bilateral trade with a broker, where a buyer and seller interact exclusively through the broker. The broker strategically maximizes her payoff through arbitrage by trading with the buyer and seller at different prices. We study whether the presence of the broker interferes with the mechanism’s gains-from-trade (GFT) achieving a constant-factor approximation to the first-best gains-from-trade (FB), in a similar vein to the constant-factor approximability without a broker by Deng, Mao, Sivan and Wang (STOC’21).
