The recent period has highlighted a well-known phenomenon, namely the existence of a positive bias in experts … contributions are twofold: we provide explanatory bias prediction models which will subsequently allow the calculation of earnings … adjusted forecasts, for horizons from 1 to 24 months. We explain the bias using macroeconomic as well as sector and firm …

This paper deals with risk measurement and portfolio optimization under risk constraints. Firstly we give an overview … of risk assessment from the viewpoint of risk theory, focusing on moment-based, distortion and spectral risk measures. We …- Gaussian features.

This chapter of a collective book aims at presenting the basics of decision making under risk. We first define notions … of risk and increasing risk and recall definitions and classifications (that are valid independently of any … representation) of behavior under risk. We then review the classical model of expected utility due to von Neumann and Morgenstern …
