Abstract
The financing structure of the healthcare system and, particularly, the voluntary health insurance (VHI) constituent, has been a vital pillar in improving the overall quality of life. Consequently, this study aims to shed light on the effect of VHI on the population’s health and longevity in a sample of 26 European OECD countries. The methodology employed covers both hierarchical clustering and the novel dynamic panel threshold technique. First, the descriptive cluster analysis unveils a delimitation of the countries into four main groups with respect to a broad set of health status indicators. Second, the estimates show that VHI is a significant determinant of health and longevity. More specifically, we find that the relationship between variables is characterized by a threshold effect, whose estimated value is roughly 6.3% of the total healthcare financing. Also, the heterogeneity analysis unveils consistent differences regarding the impact of VHI on health and longevity for the supplementary and complementary types of VHI. Overall, results are strongly robust, the signs and the significance of the coefficients being preserved in the presence of several additional control factors. From a policy perspective, the study’s findings can be used nationwide to stimulate regulatory policies to encourage the achievement of a satisfactory level of private health insurance.

Notes
For example, on the one hand, in OECD countries one of the most well-known National Health Service (NHS) is found in the UK, where English residents receive free healthcare services. On the other hand, the first social health insurance system in the world emerged in Germany, being characterized by the solidarity principle. Also, social health insurance schemes do exist in OECD countries such as Austria, France, and the Slovak Republic, among others.
Due to the lack of sufficient available data, we are not able to control for smoking.
Highest mean Rand index, measure of similarity between two data clustering.
Average linkage, single linkage, or complete linkage.
Except when there are large differences among cluster size.
The analysis of variance (ANOVA).
Although the variable VEGETABLES would have been of real interest as a control factor, we preferred not to introduce it in the regressions due to data inconsistency. For some countries, there are very severe/sharp increases or decreases from one year to another. Indeed, these fluctuations are quite difficult to explain and are rather due to changes in the estimation methodology for the national supply. Thus, given that the dependent variable does not encounter such unexpected annual variations, their presence for the VEGETABLES variable could considerably skew the panel data estimates. However, in the cluster analysis this inconvenience is diminished, as we used the multiannual averages of the variables for the analyzed period.
