In this paper we present a dynamic discrete-time model that allows to investigate the impact of risk-aversion in an …-time limit of our model with no uncertainty and no risk-aversion. Focusing on the continuous-time limit of the infinite horizon … inversely related to the degrees of uncertainty and risk-aversion. However, the effect of uncertainty and risk …

The paper clarifies the link between changes in risk aversion and the effect on the consumption discount rate. In a … rate to a change in risk aversion depends on some fundamental properties of the considered uncertainties. The application … of this general result to specific forms of uncertainty extends existing results to more general forms of risk and yields …
