The aim of this paper is to fill the gap between intertemporal growth models when the discount factor beta is close to one and when it equals one.We show that the value function and the policy function are continuous with respect both to the discount factor and the initial stock of capitalx0. We...

In this paper we propose a unifying approach to study optimal growth models with bounded or unbounded returns (above/below). We prove existence of optimal solutions. We prove also, without using contraction method, that the Value function is the unique solution to the Bellman equation in some...

We propose a new approach to the issue of existence and uniqueness of solutions to the Bellman equation, exploiting an emerging class of methods, called monotone map methods, pioneered in the work of Krasnosel'skii-Zabreiko (1984). The approach is technically simple and intuitive. It is derived...

In this paper, we first provide a framework for history-dependent utility models. We further consider discrete infinite horizon dynamic optimization programs in which the instantaneous payoff presents such historydependence. Habits are a particular case of history-dependence. An issue about...

In this paper, we provide a framework for history-dependent utility models. Habit formation is a particular case of history-dependence and there is not yet any consensus on the way to formalize habits. Our framework allows to study not only habit models that are either additive or multiplicative...
