Abstract: I use a new Call Reports data item to revisit the role of advertising in US commercial banking. I examine how banks' advertising varies with the deposit market structure and whether bank profitability is influenced by advertising. My analysis addresses the endogeneity of market structure and advertising variables using instrumental variables. I find that banks advertise more with increasing market concentration, whereas banks with larger market shares and size advertise less. I also find that advertising has a positive and economically significant impact on bank profitability. These results suggest that advertising is an important aspect of bank competition.
