We analyze a continuous-time stochastic control problem that arises in the study of several important issues in financial economics. An agent controls the drift and volatility of a diffusion output process by dynamically selecting one of an arbitrary (but finite) number of projects and the...

We consider long-run behavior of agents assessing risk in terms of dynamic convex risk measures or, equivalently, utility in terms of dynamic variational preferences in an uncertain setting. By virtue of a robust representation, we show that all uncertainty is revealed in the limit and agents...

Principal component analysis (PCA) is a widely used dimension reduction tool in the analysis of high-dimensional data. However, in many applications such as risk quantification in finance or climatology, one is interested in capturing the tail variations rather than variation around the mean. In...

A micro decision-making utility model under uncertainty is presented as a complementary foundation for macro coronavirus models. The micro model consists of two functions, a risk averse utility function depending on wellness and a wellness random output which is a function of the input variable...

We explore the attitude towards risky career choices of young people in highly competitive environments. We empirically test which factors influence young elite athletes' tendency towards choosing a high-risk career option over a lower risk one; looking at the attitudes, of close to 1000 soccer...

Current decision-making models assume that an individual's attitude towards risk does not vary across different sources. A decision maker's processing of known probabilities and the resulting degree of probability weighting should therefore be unique. This paper provides evidence that challenges...

The ability to uncover preferences from choices is fundamental for both positive economics and welfare analysis. Overwhelming evidence shows that choice is stochastic, which has given rise to random utility models as the dominant paradigm in applied microeconomics. However, as is well known, it...

Combining brokerage records and matching monthly survey measurements of a sample of individual investors from the Netherlands for the period April 2008 through March 2009, we examine how individual investors update their beliefs (return expectations and risk perceptions) and preferences (risk...
