The objective of this paper is to re-evaluate the attitude to effort of a risk-averse decision- maker in an evolving environment. In the classical analysis, the space of efforts is generally discretized. More realistic, this new approach employes a continuum of effort levels. The pres- ence of...

The objective of this paper is to correct and improve the results obtained by Van der Ploeg (1984a, 1984b) and utilized in the literature related to feedback stochastic optimal control sensitive to constant exogenous risk-aversion (Karp 1987; Whittle 1989, 1990; Chow 1993, amongst others). More...

The objective of this paper is to analyze fundamental theoretical tools employed in modelling decision making problems which involve multivariate risks. By exploiting the richness of the literature, we highlight the qualities as well as the “weaknesses” specific to a wide class of decision...
