Value-at-risk under ambiguity aversion

open access: yesFinancial Innovation, 2018
This study explored the effects of ambiguity on the calculation of Value-at-Risk (VaR) using a mathematical model based on the theory of Choquet-Brownian processes. It was found that while a moderate degree of ambiguity aversion yields a higher value for

Ambiguity Aversion and Variance Premium [PDF]

open access: yesSSRN Electronic Journal, 2012
This paper oers an ambiguity-based interpretation of variance premium— the dier- ence between risk-neutral and objective expectations of market return variance— as a com- pounding eect of both belief distortion and variance dierential regarding the uncertain economic regimes.

Updating Ambiguity Averse Preferences [PDF]

open access: yesThe B.E. Journal of Theoretical Economics, 2009
Dynamic consistency leads to Bayesian updating under expected utility. We ask what it implies for the updating of more general preferences. In this paper, we characterize dynamically consistent update rules for preference models satisfying ambiguity aversion. This characterization extends to regret-based models as well.

Ambiguity Aversion and Incompleteness of Financial Markets [PDF]

open access: yesThe Review of Economic Studies, 2001
It is widely thought that incomes risks can be shared by trading infinancial assets. But financial assets typically carry some riskidiosyncratic to them, hence, disposing incomes risk using financial assetswill involve buying into the inherent idiosyncratic risk.
