This work analyses the mortality differential between the total and the employed population for the Italian region of Liguria in 2015–2019. Values for life expectancy at ages [65, 74) are used to quantify the transfer mechanism implicitly triggered when, in the case of persistent longevity heterogeneity, a country-wide longevity factor is adopted in calculating pension annuities. Results confirm that a lower mortality force characterises the employed population of Liguria compared to the total population. In terms of implicit tax/subsidy rates, Liguria total population is almost unaffected, being taxed by an average of 0.05% of the fair value for pension. Instead, Liguria employed population is subsidised by 6.24%. Longevity heterogen...
