Abstract
This paper has two goals: (a) To model an inherent conflict of interest between a seller of a house and the real estate broker hired by the seller. In this environment, the pressure brokers exert on sellers to reduce prices generates faster sales and hence reduces sellers’ expected profit. (b) To calibrate the brokers’ commission rates that would maximize sellers’ expected gain. The calibration results may hint whether the ongoing uniform commission rate reflects collusion among real estate agencies, or should be viewed as competitive.

Notes
Clearly, the seller has the final say on the price. However, in many cases, real estate brokers have a great deal of influence on sellers’ pricing decisions, basically by providing certain information on the market thereby leading the seller to believe that the price must be lowered. In this case, the assumption that brokers set the price is not that far from reality. Brokers often exert pressure on buyers to lower their price by telling sellers that they will not be able find buyers at the price they want.
As mentioned in the introduction, sellers in the United States generally pay 6% commission and rarely bargain with their brokers on lower rates. Thus, it makes sense to assume that the commission rate is exogenously given.
I thank the referee for suggesting this extension.
