Potential factors influencing such effects include a physician\u2019s ability and the design of the ranking system itself; however, there is limited understanding of these factors. Using a controlled lab-in-the-field experiment with practicing and future physicians as subjects ([Formula: see text]), we systematically analyze effort within small teams under different ranking systems. Exogenously varying the number and position of the thresholds defining the ranking system, we observe that the addition of a threshold to create a new rank is motivating\u2014that is, increases effort\u2014only among individuals capable of exceeding that threshold; the effort of other individuals may remain unchanged or even decrease. In particular, a highly granular ranking system with ranks spanning the entire range of possible outcomes maximizes overall physician effort; high thresholds serve to motivate high-ability individuals, whereas moderate and low thresholds provide opportunities for improvement to lower-ability individuals who cannot reach the high thresholds. Our results suggest that, to motivate their teams effectively, clinical leaders should provide rank feedback using a system under which physicians of all ability types can improve their rank through increased effort.<\/jats:p>\n                  <jats:p>This paper was accepted by Stefan Scholtes, healthcare management.<\/jats:p>\n                  <jats:p>Funding: This work was supported by C-SEB Center for Social and Economic Behavior at the University of Cologne (Junior Startup Grant No: Rd04-2016-JSUG-Huesmann) and the School of Business and Economics at the University of M\u00fcnster (Junior Researcher Promotion Fund).
