Geometric discounting

Webally consider geometric discounting based on a constant dis-count factor. While this standard modeling approach has led to many elegant results, some recent studies indicate the ne-cessity of modeling time-varying discounting in certain appli-cations. This paper studies a model of infinite-horizon MDPs with time-varying discount factors. WebJul 1, 2002 · Abstract. We consider a representative–agent equilibrium model where the consumer has quasi-geometric discounting and cannot commit to future actions. We restrict attention to a parametric class for preferences and technology and solve for time-consistent competitive equilibria globally and explicitly.
