“…Over the last few decades, different authors have sought to incorporate into general equilibrium models elements such as uncertainty (Ermolieva, 2004;Auerbach and Lee, 2009), imperfect labour markets (Krueger, 2006;De la Croix, Pierrard and Sneessens, 2010), imperfect capital markets (Fehr and Habermann, 2005;Verbic, 2008;Hosseini, 2015), preferences for bequests (Kotlikoff, Smetters and Walliser, 2007) and family welfare (Fuster, Imrohoroglu ˘ and Imrohoroglu ˘, 2007;Fehr, Kallweit and Kindermann, 2015), the heterogeneity of individuals' productivity (Wang and others, 2004;Nishiyama and Smetters, 2005;Buyse, Heylen and Van De Kerckhove, 2012), risk aversion (Binswanger, 2007) and the likelihood of survival (Chauveau and Loufir, 1997), rationality-limiting elements such as myopia (Docquier, 2002;Kiraly and Simonovits, 2016;Börsch-Supan, Hartl and Leite, 2017) and inconsistent preferences (Imrohoroglu ˘, Imrohoroglu ˘ and Joines, 2003;Fehr, Habermann and Kindermann, 2006;Kumru and Thanopoulos, 2010), while also carrying out demographic projections for specific countries (Meijdam and Verbon, 1997;De Nardi, Imrohoroglu ˘ and Sargent, 1999;Börsch-Supan, Ludwig and Winter, 2006;Krueger and Ludwig, 2006). These efforts always yield quantitative results that depend on the value of the parameters assumed in the specific model.…”
