“Need and Intertemporal Choice: A Dual Goal Hypothesis”

How does a need state (e.g., hunger, sexual arousal) influence intertemporal choice? Five studies show it activates two goals: 1. Immediacy goal (“get it sooner”), which decreases patience in intertemporal choice. 2. Quantity goal (“get more”), which increases patience in intertemporal choice. In near intertemporal choices, the immediacy goal prevails and those high (vs. low) in need choose immediate gratification. In contrast, in distant intertemporal choices, the quantity goal prevails and those high (vs. low) in need opt for delayed rewards and better self-control. These findings have theoretical implications for understanding the influence of need on patience and practical implications

“Self-Assertive Interdependence: A Cultural Psychological Analysis of Arab Culture”  (Project in collaboration with Alvaro San Martin, William W. Maddux, and Shinobu Kitayama) 

Arabs represent a major cultural group and, yet, Arab culture is almost completely neglected in the current social and cultural psychological literature. Here, we addressed this gap by hypothesizing that Arab culture is characterized by a unique form of interdependence that is self-assertive. Study 1 compared Arabs, East Asians, and Westerners using implicit measures of interdependence, holistic cognition, and self-assertion. As predicted, Arabs were highly interdependent and holistic, similar to East Asians. However, Arabs also exhibited a strong tendency toward self-assertion, similar to Westerners. Studies 2 and 3 used priming procedures to show that the self-assertive tendency of Arabs is in service of interdependence, whereas the seemingly identical tendency of Westerners is in service of independence. This unique psychological profile of Arab people, demonstrated here for the first time, helps the social and behavioral science research on culture to go beyond the prevailing East-West paradigm.

"Learning From Near-Miss Events to Avoid Supply Chain Disruption."  (Project in collaboration with Ayse Onculer and Felix Papier) 

We study how operations managers learn from supply chain disruption in situations wherein disruptions are costly. We hypothesize that managers miss the opportunity to learn from near-miss events – situations where the available inventory exactly equals the demand, thus closely avoiding failure (in our case a stockout). In a controlled laboratory experiment, we observe that individuals evaluate their inventory decisions too positively after near-miss events, which leads to overly risky decisions in the subsequent periods. Also, we find that individuals who experienced near-miss events in the past have average inventory quantities that are farther away from the optimal decision, and are more likely to experience a stockout than those who haven't experienced them. Finally, our results suggest that organizational corrective measures such as the increased salience of failure and installation of a safety environment mitigate the events’ immediate, short-run effects but not their cumulative, long-run effects on inventory decisions. The salience of failure and safety environment, therefore, appear as useful de-biasing tools in the short-run, even though failure to learn from near-miss events requires additional efforts in the long-run.

"Organization Style, Leadership Strategy and Free-Riding" (Project in collaboration with Charles A. Holt and Melissa Thomas-Hunt)

Abstract : 
Organizations often match leaders with followers in order to foster cooperation, mitigate free riding, and thereby accomplish tasks effectively. This paper studies the effect of organization styles on leaders’ choices of leadership strategy, and the effect of this choice on free-riding behavior. In controlled experiments, leaders are asked to choose messages from a message set that induces a leadership style and to send it to followers in a repeated and finite horizon public goods game. When provided with collegial leadership style messages, leaders perform better than their top down counterparts, but only when targeted private communication is not allowed. When it is allowed, leaders who are instructed to be top down perform better by focusing on individuals, not the group, and by leading while accounting for contributor types. The paper uncovers core and understudied mechanisms of top down leadership, and challenges the consensus that collegiality is best for leading groups.

"Group Identity to Manipulate Social Preferences in Supply Chains with Costly Effort"  (Project in collaboration with Ulrich Thonemann and Torsten Gully)

We analyze a supply chain in which a demand planner provides demand forecasts to a production planner. The production planner uses the forecasts to decide on the production quantities and needs information about the accuracy of the forecasts to determine the appropriate safety stock levels. The accuracy of the forecast depends on the effort that the demand planner invests in forecasting. The production planner cannot observe the effort and has to form a belief about the demand planner’s effort level. If the actual effort of the demand planner and the belief of the production planner are not aligned, the overall performance of the supply chain suffers. We develop a game theoretic model to show how social preferences affect the alignment between the demand planner and the production planner. Using laboratory experiments we find support for the theoretical predictions: Some demand planners invest effort, and production planners anticipate this effort. We further show that group identity can be used to increase social preferences, thereby increasing the incentives for the demand planners to invest effort, which is anticipated by the production planners and leads to increased supply chain profitability.

"Gender Interactions in Team Production: Performance and Punishment" (Project in collaboration with Seeun Jung)

This paper analyzes the consequences of allowing for punishment in a real-effort pair production experiment. The behavior of the best performer in the team differs on whether he or she can impose a sanction on the less performing partner. When sanctions are not allowed, good performers reduce their effort in response to the advantageous difference in scores; when they can impose sanctions, their change in effort is no longer related to the difference in scores. To some extent, a sanction mechanism allows good performers to focus on their own performance. In the case of costless sanctions, not sanctioning a partner who under-performs, what we refer to as forgiveness, prompts the latter to improve his or her performance, but applying the sanction has a stronger push effect.
