Consistent with tacit knowledge accruing only with experience, and empirically exploiting a discontinuity in the formation of teams, experience relative to a peer substantially increases the size of variation attributable to the physician trainees. Among the same physician trainees, convergence occurs for patients on services driven by specialists, where there is arguably more explicit knowledge, but not on the general medicine service. This difference is unexplained by formally coded patient information. In contrast, rich physician characteristics correlated with preferences and ability, and quasi-random assignments to high- or low-spending supervising physicians explain little if any variation. http://www.nber.org/papers/w21855 Full text for the University of St. Gallen Metadata Rights Reserved ids I noalma ids I IDSSG 100 1- Jr David C.
