I'm doing some bibliographic research on mathematical models for personal finance decisions. I should like to ask whether you know any of them, because the research that I did on Google Scholar haven't produced anything. To be precise, I looked up the words combinations "personal finance decision" "mathematical model", "personal finance decision" game, "personal finance" "nash equilibria", "personal finance" "nash equilibrium" and "personal finance" "mathematical model".
Thank you in advance.
