Brokers vs. Retail Investors: Conflicting Interests and Dominated Products

Format:Print

Abstract

I study how brokers distort household investment decisions. Using a novel convertible bond dataset, I find that consumers often purchase dominated bonds—cheap and expensive versions of otherwise identical bonds coexist in the market. The empirical evidence suggests that broker incentives are responsible for the inferior investments, as brokers earn a 1.12 percentage point higher fee relative to the notional invested for selling the dominated bond on average. I develop and estimate a broker intermediated search model that rationalizes this behavior and quantifies the distortions in these markets. In the model, consumer search is endogenously directed according to the incentives of brokers, and brokers price discriminate based on a consumer's level of sophistication. The model estimates indicate that costly search is a key friction in retail financial markets, but the effects of search costs are compounded when brokers are incentivized to direct the search of consumers towards high fee inferior products.
