| Subjective Discount Factors |
| Session: C-1-24 Friday 11 August 2000 by Luttmer, Erzo G. J. |
| This paper describes the equilibrium of an endowment economy in which consumers with arbitrary subjective discount factors and quasi-homothetic period utility functions follow Markov strategies. Explicit expressions are given for state prices and consumption-wealth ratios. If utility is logarithmic or endowment growth is \emph{i.i.d.}, then this economy is observationally equivalent to one in which consumers discount geometrically. We examine the effects of non-geometric subjective discount factors in an economy in which habits induce serial dependence in net-of-habit endowment growth rates. |
