“…One of the main challenges in the actuarial sector of such entities is to determine the actuarial rate, which is levied on the participants' income, necessary to honor social security commitments for the payment of normal retirement (Afonso & Lima, 2011;Heiland & Yin, 2014;Souza, 2018), disability retirement and dependents' pensions (Belloni & Maccheroni, 2013;Corrêa, 2018;Gouveia, Souza, & Rêgo, 2018). The concept of actuarial justice (Queisser & Whitehouse, 2006) supports investigating how such rates are affected by changes in the plan's modality (Alonso-García, Boado-Penas, & Devolder, 2018;Rodrigues & Afonso, 2015), alteration of retirement rules (Martins & Campani, 2019), and increased longevity (Gouveia et al, 2018) applied to general social security (Freire & Afonso, 2015), private pension of public workers (Rangel & Saboia, 2013;Rodrigues & Afonso, 2015), and the RPPS (Corrêa, 2018).…”
