This note reconsiders the unit root properties of health care expenditure (HCE) and gross domestic product (GDP) for OECD countries. The time-series properties of this data set has been much discussed in the literature with contrasting results from the application of a range of test procedures. We use a recently developed test to examine the relationship between the two variables. The results in this paper confirm earlier findings that when the data are considered as a panel, there is strong evidence of unit roots in both GDP and HCE data.
