RT Journal Article SR Electronic T1 Missing Work Is a Pain JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 71 OP 122 DO 10.3368/jhr.53.1.0215-6958R1 VO 53 IS 1 A1 Aline Bütikofer A1 Meghan M. Skira YR 2018 UL http://jhr.uwpress.org/content/53/1/71.abstract AB How does medical innovation affect labor supply? We analyze how the availability of Cox-2 inhibitors, pharmaceuticals used for treating pain and inflammation, affected the sickness absence and disability pension receipt of individuals with joint pain. We exploit the market entry of the Cox-2 inhibitor Vioxx and its sudden market withdrawal as exogenous sources of variation in drug use. Using Norwegian administrative data, we find Vioxx’s entry decreased quarterly sickness absence days among individuals with joint pain by 7–12 percent. The withdrawal increased sickness days by 12–16 percent and increased the quarterly probability of receiving disability benefits by 6–15 percent.
