Rankings are omnipresent in the finance industry, yet the literature is silent on how they impact financial professionals' behavior. Using lab-in-the-field experiments with 657 professionals and lab experiments with 432 students, we investigate how rank incentives affect investment decisions. We find that both rank and tournament incentives increase risk-taking among underperforming professionals, while only tournament incentives affect students. This rank effect is robust to the experimental frame (investment frame vs. abstract frame), to payoff consequences (own return vs. family return), to social identity priming (private identity vs. professional identity), and to professionals' gender (no gender differences among professionals).IN RECENT YEARS, EXCESSIVE RISK-TAKING in the finance industry has been depicted as one of the main factors contributing to the global financial crisis * All authors contributed equally. Michael Kirchler is in the (Financial Crisis Inquiry Commission (2011), Dewatripont and Freixas (2012)). In particular, bonus schemes and tournament incentives have been identified as among the main drivers of excessive risk-taking in developed financial markets (Rajan (2006), Diamond and Rajan (2009), Bebchuk and Spamann (2010)). Tournament incentives are characterized by two major components. The first and more obvious component comprises salary and other material rewards that depend on performance, which create rank-dependent "monetary incentives" to outperform others. The second and less obvious component comprises "nonmonetary incentives" to outperform peers. This second component-called "rank incentives"-provides utility to those at the top of the ranking and disutility to those at the bottom (Barankay (2015)) and thus captures relative performance preferences. 1 These nonmonetary, relative performance preferences can be driven by the desire for a positive self-image (Bénabou and Tirole (2006), Köszegi (2006)), or by concerns about public status (Frank (1985), Moldovanu, Sela, and Shi (2007)). Hence, rank incentives play a prominent, explicit role in tournaments. In the finance industry, rankings, ratings, and awards are the visible hallmarks of a strong culture of relative performance measurement and social competition. Funds are ranked or rated annually as are their managers. 2 Awards to the "Fund Manager of the Year," "Banker of the Year," or "Analyst of the Year" are sought-after distinctions in many areas of finance. 3 More informally, financial professionals (henceforth, professionals) often compare themselves with others in discussions about their investments and successes ("cheap talk"; see Crawford (1998)), effectively ranking each other on an ongoing basis. Recent evidence from laboratory and field experiments shows that, on average, rank incentives increase individuals' effort and performance (Azmat and Iriberri (2010), Blanes-i-Vidal and Nossol (2011), Tran and Zeckhauser (2012), Bandiera, Barankay, and Rasul (2013), Delfgaauw et al. (2013)), but they also promote unethical behavior...
