A General Class of Multivariate Skew-Elliptical Distributions
Journal of Multivariate Analysis, 2001 Let \({\mathbf X}= (X_1,\dots, X_k)^T\) be a random vector elliptically distributed with location vector \(\mu\in \mathbb{R}^k\) and \(k\times k\) (positive definite) dispersion matrix \(\Sigma\), and assume that the vector \((X_0, X_1,\dots, X_k)^T\) is also elliptically distributed with location vector \((0,\mu)\) and dispersion matrix \(\left ...

Takeover Vulnerability and the Discipline of ESG Overinvestment
Business Strategy and the Environment, EarlyView.ABSTRACT While takeovers serve a disciplinary role by replacing inefficient managers, the threat of takeovers may compel firms to divert attention from Environmental, Social and Governance (ESG) efforts as a strategic response to external pressure, especially when such firms are already overinvesting in ESG.

Skew-normal shocks in the linear state space form DSGE model [PDF]
Observed macroeconomic data – notably GDP growth rate, inflation and interest rates – can be, and usually are skewed. Economists attempt to fit models to data by matching first and second moments or co-moments, but skewness is usually neglected. It is so

Random orthogonal matrix simulation with exact means, covariances, and multivariate skewness
, 2017 © 2017 Elsevier B.V. We develop a simulation algorithm that generates multivariate samples with exact means, covariances, and multivariate skewness. If required for financial applications, absence of arbitrage can be ensured.
