Abstract: We examine how the research departments of brokerage firms may issue biased recommendations in order to boost the revenue of the investment banking departments of the brokerage firms during 1993-2006. We find that during 1993-2006, sanctioned brokerage firms| upgrades not only underperformed the upgrades of non-sanctioned brokerage firms, but they also earned negative abnormal returns. The degree of underperformance for sanctioned brokerage firms| upgrades was at the highest during 1999-2002. More surprisingly, the underperformance of upgrades continues in 2003-2006. We also find weak evidence of underperformance of upgrades in the period of 1993-1998.
