It is a clear policy priority to understand the clinical and economic trade-offs associated with high patient cost sharing for essential medications. This is especially true as the level of cost sharing faced by commercially insured patients continues to increase,20 and the economy stagnates. While Philipson et al’s results are consistent with a large literature on this topic, their analysis highlights the challenges in quantifying a relationship that seems to be a truism.
