Nature, 2006 We analyze a simple overlapping‐generations model with two capital goods. The dynamical system is defined by savings behavior and short‐run perfect‐foresight asset‐market clearing. Because lifetimes are finite, there is no transversality condition. If there is a bubble in asset pricing, it will burst in finite time: expectations will eventually be ...
