Missing Work Is a Pain

How does medical innovation affect labor supply? We analyze how the availability of Cox-2 inhibitors, \npharmaceuticals used for treating pain and inflammation, affected the sickness absence and disability \npension receipt of individuals with joint pain. We exploit the market entry of the Cox-2 inhibitor Vioxx \nand its sudden market withdrawal as exogenous sources of variation in drug use. Using Norwegian \nadministrative data, we find Vioxx’s entry decreased quarterly sickness absence days among individuals \nwith joint pain by 7-11 percent. The withdrawal increased sickness days by 12-21 percent and increased \nthe quarterly probability of receiving disability benefits by 0.4-0.6 percentage points.
