A behavioral model of simultaneous borrowing and saving

  • Basu, Karna

Why do individuals borrow and save money at the same time? I present a model in which sophisticated time-inconsistent agents, when faced with a future investment opportunity, rationally choose to save their wealth and then borrow to fund the investment. The combination of savings and a loan generates incentives for future selves to invest optimally by punishing over-consumption. This paper contains two main results. First, I show that agents who simultaneously save and borrow can have higher lifetime welfare than those who don’t. Second, I show that agents who have access to a non-secure savings technology can be better off than those who only have access to secure savings.
