Objectives: This study investigates the possibility of multiple healthcare bubbles in the US healthcare market.

Methods: We first applied the newly developed Generalized Sup ADF test to locate multiple healthcare bubble episodes and then estimated the switching regression model specifying multiple healthcare bubble periods to evaluate to what extent macroeconomic variables (such as the interest rate, public debt, and fiscal deficit) and public financing healthcare programs influence the magnitude of healthcare bubbles in terms of the deviation of the medical care price inflation from either the overall price inflation or the money wage growth.

Results: Our results show that expansionary monetary and fiscal policies play important roles in determining the deviation of the medical care price inflation from the overall price inflation and that the net government debt has a positive impact on the deviation of the medical care price inflation from the money wage growth.
