“…The use of modelling and mathematical optimization tools to support decision‐making in the social security field is not new. Several projects have attempted to design models to optimize the performance of specific pension systems, often with a greater emphasis on reducing the deficit (Vidal‐Meliá, Boado‐Penas and Settergren, 2009; El Goumi, El Khomssi and Fikri, 2016), either by manipulating minimum retirement ages (Sayan and Kiraci, 2001; Heeringa and Bovenberg, 2012), the annual inflow of immigrants (Angrisani et al, 2012; Pianese, Attias and Vargas, 2014), employee and employer contribution rates (Alonso, Hoyo and Tuesta, 2014; Peng, Hsiao and Yao, 2016; Godínez‐Olivares, Boado‐Penas and Pantelous, 2016) replacement rates (Attias et al, 2016; Nepp et al, 2018), or by advocating a combination of parametric reforms such as raising the minimum retirement age and contribution rates rather than making structural changes to financing schemes (Madeiros García and Graça Lopes, 2009). To date, there have been no such studies looking at Argentina’s pension system.…”
