This paper studies the consumption-investment problem of a consumer with a multi-period planning horizon under uncertainty. Such a setting occurs naturally in stochastic OLG models with multi-period-lived consumers. We provide a rigorous characterization of consumption-investment strategies...

This note studies a general nonstationary infinite-horizon optimization problem in discrete time. We allow the state space in each period to be an arbitrary set, and the return function in each period to be unbounded. We do not require discounting, and do not require the constraint...

We investigate the key determinants of the optimal direct mail policy in a dynamic environment where customers maximize utility and the direct mailer maximizes profits. We measure the sensitivity of the customers to receiving a catalog in the mail, while controlling for customer characteristics...
