Trust in others' honesty is a key component of the long-term performance of firms, industries, and even whole countries. However, in recent years, numerous scandals involving fraud have undermined confidence in the financial industry. Contemporary commentators have attributed these scandals to the financial sector's business culture, but no scientific evidence supports this claim. Here we show that employees of a large, international bank behave, on average, honestly in a control condition. However, when their professional identity as bank employees is rendered salient, a significant proportion of them become dishonest. This effect is specific to bank employees because control experiments with employees from other industries and with students show that they do not become more dishonest when their professional identity or bank-related items are rendered salient. Our results thus suggest that the prevailing business culture in the banking industry weakens and undermines the honesty norm, implying that measures to re-establish an honest culture are very important.
Countercyclical risk aversion can explain major puzzles such as the high volatility of asset prices. Evidence for its existence is, however, scarce because of the host of factors that simultaneously change during financial cycles. We circumvent these problems by priming financial professionals with either a boom or a bust scenario. Subjects primed with a financial bust were substantially more fearful and risk averse than those primed with a boom, suggesting that fear may play an important role in countercyclical risk aversion. The mechanism described here is relevant for theory and may explain self-reinforcing processes that amplify market dynamics. (JEL E32, E44, G01, G11, G12)
Social comparison processes have potentially far reaching consequences for many economic domains. We conducted a randomized field experiment to examine how social comparison affects workers' effort provision if their own wage or the wage of a co-worker is cut. Workers were assigned to groups of two, performed identical individual tasks, and received the same performanceindependent hourly wage. Cutting both group members' wages caused a decrease in performance. But when only one group member's wage was cut, the affected workers decreased their performance more than twice as much as when both workers' wages were cut. This finding indicates that social comparison processes among workers affect effort provision because the only difference between the two wage-cut treatments is the other group member's wage level. In contrast, workers whose wage was not cut but who witnessed their group member's pay being cut displayed no change in performance relative to the baseline treatment in which both workers' wages remained unchanged. This indicates that social comparison exerts asymmetric effects on effort. Abstract: Social comparison processes have potentially far reaching consequences for many economic domains.

We analyze the bidding behavior of expectations-based loss-averse bidders in auctions with interdependent values. We emphasize the difference between the risk bidders face over whether they win the auction (extensive risk) and the risk they face over the value of the prize conditional on winning (intensive risk). The extensive risk creates an "attachment" effect, whereas the intensive risk operates via a "comparison" effect. How loss-averse bidders react to these different risks depends on whether they incorporate their bid into their reference point. Under "unacclimating personal equilibrium" (UPE), where bidders keep their expectations fixed when choosing their bids, both the extensive and intensive risks induce them to bid more aggressively. Moreover, bidders are exposed to the "winner's curse" and a seller can attain higher revenue by hiding information in order to leverage the intensive risk. By contrast, under "choice-acclimating personal equilibrium" (CPE), where a bid determines both the reference lottery and the outcome lottery, the intensive risk creates a "precautionary bidding" effect that pushes bidders to behave less aggressively; whether this effect is reinforced or undermined by the extensive risk depends on a bidder's likelihood of winning the auction. Furthermore, bidders are less aggressive than under UPE and can be subject to a "loser's curse." Yet, by committing to bidding less aggressively, such as by engaging in proxy bidding, loss-averse bidders are better off under CPE than UPE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
