Transaction costs are thought to affect asset prices and market liquidity, but the direction and magnitude of these effects continue to be the subject of debate. In the single-family residential market, discount brokers offer to list a house for a lower price and thus reduce the transaction costs associated with obtaining a match. In this article we obtain empirical estimates of the price and liquidity impact of a seller selecting a discount broker to market a singlefamily residential property. The unique data set allows for the identification of residential properties that were listed by a discount brokerage firm. The empirical results confirm the predictions of our theoretical model. Using a sample of 318,221 listings and 243,625 sales, we find that houses listed by discount brokers sell at prices similar to non-discount brokerage listings, but are less likely to sell, and when they do sell, take approximately three days longer to sell. The results indicate that lower transaction costs do not impact housing prices in this market, but that they are related to asset liquidity.In this article, we examine discount real estate listing agreements and their impact on the welfare of sellers of residential property. Sellers in real estate markets face imperfect information about the market value of their assets and the location of potential buyers. This creates a role for real estate agents who can help sellers by employing their superior search technology to locate prospective buyers and by using their superior knowledge of the market to suggest an optimal asking price. In return for their services, agents typically receive a percentage (generally 5 to 7%) of the transaction price as commission. The significance of the role played by agents is evident: they accounted for the sale of approximately 84% of single-family dwellings in the housing market in 2008. 1 Based on the expected number of home sales of 5.8 million units, the average selling price of $214,500 and the typical commission rates of 5 to
