Many risk, inequality, poverty and concentration measures are extremely sensitive to outliers, dependence, heterogeneity and heavy tails. In this paper we focus on robust measurement of risk, inequality, poverty and concentration under heterogeneity, dependence and heavy-tailedness of largely unknown form using the recent results on t−statistic based heterogeneity and correlation robust inferen...

We solve a liquidation problem for an agent with preferences consistent with the prospect theory of Kahneman and Tversky (1979). We find that the agent is willing to hold a risky project with a relatively inferior Sharpe ratio if the project is currently making losses, and intends to liquidate it when it breaks even. On the other hand, the agent may liquidate a project with a relatively superio...

For the past two decades, derivatives provided the core financial innovation for riskmanagement and risk-sharing activities. However, in the aftermath of the 2007-2008 crisis, derivatives have started received, partly for good reason, an increasingly bad press. The main purpose of this paper is to lay the foundations for a theoretical framework in which systemic risk is centrally involved in th...

We propose a new luminosity function, V ð1Þ, that improves upon the original CIE 1924 Vð1Þ function and its modification by D. B. Judd (1951) and J. J. Vos (1978), while being consistent with a linear combination of the A. Stockman & L. T. Sharpe (2000) long-wavelength-sensitive (L) and middle-wavelength-sensitive (M) cone fundamentals. It is based on experimentally determined 25 Hz, 2diameter,...

Portfolio asset management must minimize risk exposure for the investor. Measuring performance of any instrument can be done by looking at risk-reward. Observe stock listed in BUMN 20 Index with measurement analytical tools like Sharpe ratio, Treynor Ratio, and Sortino ratio. This study is descriptive quantitative research as this aims to explain how ratio between 2018 2021. All population focu...
