in this article the researcher, comparing semivariance and calculated beta on basis of it to the variance and common beta, has tried to see whether downside beta criteria (semivariance and calculated beta on basis of it) have any preference over the common risk criteria (variance and common bata) or not. in order to achieve this, weekly data of 55 sample companies were gathered in a 6-year peri...

The problem of portfolio risk estimation in volatile markets requires employing fat-tailed models for financial instrument returns combined with copula functions to capture asymmetries in dependence and a true downside risk measure for risk estimation. In this survey, we discuss how these three essential components can be combined together in a Monte Carlo based framework for risk estimation an...

We study the coordination of supply chains with a risk-neutral supplier and a risk-averse retailer. Different from the downside risk setting, in a conditional value-at-risk (CVaR) framework, we show that the supply chain can be coordinated with the revenue-sharing, buy-back, two-part tariff and quantity flexibility contracts. Furthermore the revenuesharing contracts are still equivalent to the ...

Recent experience in capital markets has highlighted the need for risk-sensitive portfolio strategies in both domestic investment grade as well as opportunistic high-yield and emerging market portfolios. We have previously developed a fixed-income sector optimization methodology to facilitate tradeoffs between various sectors based on their contribution to the total portfolio return and risk. W...

This paper examines the intertemporal relation between downside risk and expected stock returns. Value at risk (VaR), expected shortfall, and tail risk are used as measures of downside risk to determine the existence and significance of a risk-return tradeoff for several stock market indices. We find a positive and significant relation between downside risk and the portfolio returns on the NYSE...

Coordinating supply chains has been a major issue in supply chain management research. This paper focuses on the coordination of supply chains with downside-risk-averse agents. Motivating by the revenue sharing contract, we developed the sufficient conditions for the coordination of the supply chain with one downside-risk-averse agent. Following the sufficient conditions, the downside protectio...

We document a substantial increase in downside risk to US economic growth over the last 30 years. By modelling secular trends and cyclical changes of predictive density GDP growth, we find an accelerating decline skewness conditional distributions, with significant, procyclical variations. Decreasing trend-skewness, which turned negative aftermath Great Recession, is associated long-run slowdow...
