Profit distribution and managers' behaviour in vertical integrated medical delivery systems - an experimental economics study

The vertical integration of medical delivery systems (VIMDSs) is a reform direction both in China and worldwide. We conducted a controlled economic experiment to explore decision-making by managers of medical institutions with respect to profits and what influences the distribution mechanism in VIMDSs.

There was a significant correlation between the improvement rate and the choice of effort level (P
