Abstract
Demographic ageing that is already evident
in many OECD countries will become more acute in the coming decades. The costs
associated with this phenomenon are most apparent in spending on pensions,
healthcare and long-term care. Among the solutions put forward to deal with
this, the productivity of human capital is the one we propose and analyze.
According to Mincer's theory, the salary, which represents the reward for
production, is the variable that we propose to use in the analysis of human
capital productivity. Salary is the materialization of work done, so the higher
it is, the more productive it is. Salary variation is therefore our dependent
variable and spending on pensions and healthcare are our key independent
variables. Our analysis covers 33 of the 37 countries that make up the OECD
system. We use the ordinary least squares method on panel data covering the
period 2000-2020. Our key independent variables show a negative correlation
with salary variation. This would mean that an increase in spending on pensions
and healthcare would lead to a reduction in salaries to cover these costs.
However, as our education variables (average years of study, employment rate of
secondary and tertiary graduates...) show a positive correlation with salary
variation, we can undoubtedly state that improving human capital through
education and training is the solution to be encouraged by the public
authorities in a context of ageing.
