RETHINKING SUSTAINABILITY IN AGEING SOCIETIES: THE ROLE OF LONG-TERM CARE EXPENDITURE IN OECD COUNTRIES

Abstract

Population ageing has become an important policy concern for the sustainability of healthcare systems, particularly in OECD countries. Although the relationship between ageing and healthcare expenditure has been widely examined in the literature, the association between long-term care expenditure and healthcare expenditure has received relatively limited attention. This study aims to examine the relationship between population ageing, long-term care expenditure, and healthcare expenditure using panel data from 33 OECD countries covering the period 2000–2023. The analysis employs panel data techniques, including pooled Ordinary Least Squares (OLS), Fixed Effects, and Random Effects models, together with several diagnostic tests. The empirical findings indicate that both population ageing and long-term care expenditure are positively and statistically significantly associated with healthcare expenditure. According to the final model, a 1% increase in the proportion of the population aged 65 and above is associated with an approximately 0.32% increase in healthcare expenditure. Similarly, a 1% increase in long-term care expenditure is associated with an approximately 0.08% increase in healthcare expenditure. In contrast, GDP per capita was not found to be statistically significant. The results also reveal significant cross-sectional dependence among countries. Overall, the study suggests that healthcare expenditure in ageing societies may be associated with both demographic and institutional factors and highlights the importance of considering long-term care systems when evaluating healthcare system sustainability.
