In order to encompass the possible effect of several generally
uncountable factors, three stylised scenarios have been proposed. Two of them use
similar methodological tool, whereby the unit cost of health care spending is assumed to
follow over time a development path varying from the basic GDP per capita growth rate.
The third one uses a more sophisticated methodology, whereby an econometric analysis
of past trends in health care expenditure drivers enables the estimation of the coefficients
of correlation used later in projecting future evolution of costs.
