On the determination of the US aggregate health care expenditure
Per capita real health care expenditure is examined against three major groups of explanatory variables: economic, demographic, and health stock, and it is found that the three groups of variables have an impact on real health care spending. Other subcategories, such as real private, and government health care, pharmaceutical, dental, home nursing, ambulatory, personal medical consumption, and in-patient expenditures have also been examined, and have been found to be affected by the explanatory variables. For several subcomponents there is evidence of supplier inducement. Of the demographic group of variables, the ageing population had an impact only on the per capita real overall, and private health care outlay, and pharmaceutical spending. Also, cointegrating relationships were found and consistent estimators of the elasticities found.
