This study analyses price effects of six mergers in the Dutch healthcare industry. We investigate whether the merging hospitals raised their prices for hip surgery after the merger and, if so, how patients react to this higher price. For seven of the twelve hospitals involved, we found a statistically significant price increase for hip surgery, for three hospitals we found a significant price decrease. There is no clear relationship between price changes of hip surgery and changes in travelling behaviour of patients post merger.
