"Conflict of Interest? - The Impact of Real Estate Dual Agency on the Price and Speed of Residential Real Estate Transactions"
Vrinda Kadiyali, Jeffrey Prince, and Daniel H. Simon (October 2007) examined the effects of dual agency in real estate transactions because of conflict of interest concerns. They found that dual agency benefits buyers and sellers by "offering transaction efficiencies and expanding the pools of houses and buyers that an agency can try to match with each other."
They assessed dual agency's impact on the prices and speed of transaction, discovering that dual agency has no effect on average sale price, but does tend to reduce by about 7% the time to sale, which is roughly six days; usually a benefit to both sides of the transaction.
