When firms are better informed than their consumers---for example, in many service industries firms know more than their customers about the benefits of different alternatives---competitive pressure may inhibit efficiency because it forces firms to cater excessively to consumers' opinions. We develop this idea in a simple model of investment management in which agency problems are absent. We show that competitive pressure may prevent firms from using information that contradicts consumers' prior beliefs. In particular, the inefficiency occurs when the firms' informational advantage is small, and may, in fact, be exacerbated by making the consumer better informed. By contrast, the inefficiency shrinks with the number of firms. Ordering information: This article can be ordered from https://pubs3.rand.org/cgi-bin/rje/pdf.cgi.
