We investigate whether the media plays a role in corporate governance by disseminating news. Using a comprehensive data set of corporate and insider news coverage for the 2001–2012 period, we show that the media reduces insiders’ future trading profits by disseminating news on prior insiders’ trades available from regulatory filings. We find support for three economic mechanisms underlying the disciplining effect of news dissemination: the reduction of information asymmetry, concerns regarding litigation risk, and the impact on insiders’ personal wealth and reputation. Our findings provide new insights into the real effect of news dissemination.

Theory predicts that capping brokers’ compensation exacerbates the exploitation of retail investors. We show that regulated caps on mutual fund 12b-1 fees, effectively sales commissions, are associated with negative equity fund performance, but only after a structural shift toward maximum permitted levels of the fees around 2000. Past this break point, flow–performance sensitivity shifts from the middle- to the highest-performing funds, suggesting that the fee cap increases performance-chasing behavior by constraining brokers’ incentives to learn about lower-ranked funds. The policy implication is that regulators must reevaluate the efficacy of caps on brokerage fees.
