Okay, okay, that’s not quite the message of a new working paper by Panle Jia Barwick and Parag A. Pathak called “The Costs of Free Entry: An Empirical Study of Real Estate Agents in Greater Boston.” But for those of us who have thought about the Realtor’s role in the housing market, it’s tempting to jump to that conclusion. Here’s the full version of the study, and here’s the abstract:
This paper studies the real estate brokerage industry in Greater Boston, an industry with low entry barriers and substantial turnover. Using a comprehensive dataset of agents and transactions from 1998-2007, we find that entry does not increase sales probabilities or reduce the time it takes for properties to sell, decreases the market share of experienced agents, and leads to a reduction in average service quality. These empirical patterns motivate an econometric model of the dynamic optimizing behavior of agents that serves as the foundation for simulating counterfactual market structures. A one-half reduction in the commission rate leads to a 73% increase in the number of houses each agent sells and benefits consumers by about $2 billion. House price appreciation in the first half of the 2000s accounts for 24% of overall entry and a 31% decline in the number of houses sold by each agent. Low cost programs that provide information about past agent performance have the potential to increase overall productivity and generate significant social savings.
And where is all that money going that’s not being spent on home sales? Maybe … the Zillow IPO.
And just for kicks, here’s a clip from the Freakonomics movie in which Levitt and I ask the question: Does your real estate agent really have your best interest in mind?
