The Welfare Effects of Non-Price Competition Among Real Estate Brokers

This paper examines the role of brokers in economizing on transaction costs in the housing market. By lowering the cost of transactions, brokers create welfare gains compared to a market in which buyers and sellers transact on their own. However, if brokers engage in unproductive, non-price competition to acquire a larger share of available listings, then some of the welfare gains are dissipated. Using a partial equilibrium model, this paper shows how an excessive commission rate can lead to this result.
