The theory of decision under uncertainty has been extensively developed last years and it is yielding interesting consequences within economic theory. Nevertheless, there are so much work to do involving such innovations and general equilibrium models, in particular the survival problem. In this paper is supposed that agents’ behaviors are determined by variational preferences (axiomatized by Macheroni et al. (2006a,b)). Those preferences are more general than expected utility (used by Sandroni (2000) and Blume and Easley (2006)) and maxmin utility (used by Condie (2008)). Condie (2008)’s main result, which indicates a difficulty in the survival of uncertainty averse agents, is gene- ralized for the variational case, but it is shown that an agent survives if his uncertainty aversion vanishes.
