The agency role of the physician in Ireland, Britain, and the USA

The USA and Britain have medical care delivery and financing systems which are polar opposites. The Irish system incorporates important features of both. Using original household survey data of medical care utilization in Ireland, and published data and studies of the USA and Britain, the effect of the incentive structures in the three systems on physician behavior, especially on the so-called agency role, is examined. We conclude that the incentive structure is of the utmost importance to policy makers concerned with health costs and economic rationality of medical care systems.
