Both stochastic dominance and Omegaratio can be used to examine whether the market is efficient, whether there is any arbitrage opportunity in the market and whether there is any anomaly in the market. In this paper, we first study the relationship between stochastic dominance and the Omega...

It is well-known that under some conditions, the mean-variance rule is equivalent to stochastic dominance rule. Some academics hypothesize that there could exist mean-Omega ratio rule that could be equivalent to stochastic dominance rule under certain conditions. To explore this possible, in...

This paper is on decision theoretical foundations for various types of VaR models, including VaR and conditional-VaR, as objective measures of downside risk for financial prospects. We establish the connections of the VaRs with the first- and the second-order stochastic dominance investment...

This article aims to build through the collection of inputs from prior research, regulatory input and practitioner's experience, a comprehensive definition of risk.Risk is not measurable uncertainty nor volatility. Risk is a three part concept: (1) risk is the potential that events may have an...

This paper considers the problem of measuring the exposure to dependence risk carried by a portfolio with an arbitrary number of two-asset derivative contracts. We develop a worst-case risk measure computed over a set of dependence scenarios within a divergence restricted region. The set of...

I develop a model of statistical arbitrage trading in an environment with "fat-tailed" information. If risk-neutral arbitrageurs are uncertain about the variance of fat-tail shocks and if they implement max-min robust optimization, they will choose to ignore a wide range of pricing errors....

We present three modules that can be used in finance and investment courses to introduce undergraduate students to cryptocurrency risks and returns. Detailed instructions include learning objectives, assignment instructions, and links to free online resources. In Module 1, students are provided...

The topic of risk incorporates a variety of definitions within different fields such as psychology, sociology, finance, and engineering. In academic finance, the analysis of risk has two major perspectives known as standard (traditional) finance and behavioral finance. The central focus of...

This paper refines the framework proposed by Beal et al (2005) and by applying Tobin's Liquidity Preference Theory (Tobin, 1958) to describe individual attitudes toward risk, and identifies a number of SRI investor profiles based on their attitude to risk

The present paper studies the influence of institutions upon the risk incurred in alternative capital markets, in the lines of the old institutional school of economics. A game-theoretic model is introduced, presenting the alternative capital markets as Harsanyi's games with imperfect...
