We measure risk preferences for decisions that involve more than a single monetary attribute. According to theory, the … multivariate risk preferences correlation aversion, cross-prudence (coskewness preference) and cross-temperance (cokurtosis … aversion) determine how univariate risk preferences over attributes co-vary and interact. We obtain model-free measurements of …

The concept of “overconfidence” is one of the great success stories of psychological research, influencing discourse in the popular press, business, and public policy. Relative to underconfidence, overconfidence at various tasks is purportedly associated with greater narcissism, lower...

We extend the definition of a convex risk measure to a conditional framework where additional information is available …. We characterize these risk measures through the associated acceptance sets and prove a representation result in terms of … conditional expectations. As an example we consider the class of conditional entropic risk measures. A new regularity property of …

This paper develops a new way to quantify the effect of uncertainty and other higher-order moments. First, we estimate a nonlinear model using Bayesian methods with data on uncertainty, in addition to common macro time series. This key step allows us to decompose the exogenous and endogenous...

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. We deal with the problem of portfolio optimization under risk constraints and lead a comparative analysis of …

In view of the recent financial crisis systemic risk has become a very important research object. It is of significant … crises. Systemic risk measures can provide more insight on this aspect. The study of systemic risk measures should support … central banks and financial regulators with information that allows for better decision making and better risk man- agement …

This paper investigates how welfare losses for facing risks change as the risk environment of the decision-maker is … altered. To that aim, we define the risk apportionment of order n (RA-n) utility premium as a measure of pain associated with … facing the passage from one risk to a riskier one. Changes in risks are expressed through the concept of stochastic dominance …
