The Burbea-Rao and Bhattacharyya centroids [PDF]

, 2011
We study the centroid with respect to the class of information-theoretic Burbea-Rao divergences that generalize the celebrated Jensen-Shannon divergence by measuring the non-negative Jensen difference induced by a strictly convex and differentiable ...

Mortality Forecasting Using Variational Inference

Journal of Forecasting, EarlyView.
ABSTRACT This paper considers the problem of forecasting mortality rates. A large number of models have already been proposed for this task, but they generally have the disadvantage of either estimating the model in a two‐step process, possibly losing efficiency, or relying on methods that are cumbersome for the practitioner to use.

How Important Is Pay and What Are the Effects (Positive and Negative) of Pay for Performance?: Evaluating Claims and Evidence

Human Resource Management, EarlyView.
ABSTRACT Compensation plays a pivotal role in shaping employee behavior, motivation, and well‐being. Although extant research has explored various dimensions of compensation, questions about how important pay is to employees and concerns (on the part of employers and/or employees) about the unintended negative (in addition to intended positive ...

Necessary and sufficient conditions for discrete inequalities of Jensen–Steffensen type with applications

Journal of Inequalities and Applications
In this paper we give a necessary and sufficient condition for the discrete Jensen inequality to be satisfied for real (not necessarily nonnegative) weights. The result generalizes and completes the classical Jensen–Steffensen inequality. The validity of

ESG Performance and Credit Risk: Evidence From Chinese Manufacturing Companies

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates the effect of corporate environmental, social, and governance (ESG) performance on credit risk using a sample of manufacturing firms listed on China's Shanghai and Shenzhen A‐share markets from 2009 to 2021. Employing fixed effects, the generalised method of moments, and instrumental variable models, we find that ...

Around Jensen's inequality

Demonstratio Mathematica, 1994
Let \(\tau\) be a normal semifinite trace on a von Neumann algebra \(A\), let \(\alpha: A\to A\) be a positive linear contraction and let \(a= a^*\in A\). If \(f\) is a continuous convex function defined on the spectrum of \(a\), then it is shown that if \(\tau(\alpha(f(a))_+)< \infty\) then either \(\tau((f(\alpha(a)))_+)< \infty\) or \(\tau((f(\alpha(

Inconsistency of the Capital Asset Pricing Model in a Multi‐Currency Environment

International Journal of Finance &Economics, EarlyView.
ABSTRACT The capital asset pricing model (CAPM) is a widely adopted model in asset pricing theory and portfolio construction because of its intuitive nature. One of its main conclusions is that there exists a global market portfolio that each rational investor should hold in proportion to the risk‐free asset. In this paper, we demonstrate theoretically

Generalized Niezgoda's Inequality with Refinements and Applications [PDF]

Sahand Communications in Mathematical Analysis
Motivated by the results of Niezgoda, corresponding to the generalization of Mercer's inequality for positive weights, in this paper, we consider real weights, for which we establish related results.

Socioeconomic impact on quality of care in pelvic gynecological cancers

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Introduction Several European studies have shown health‐related social inequalities in pelvic gynecological cancers, with a social gradient in incidence and mortality, partly explained by more advanced stages at diagnosis in low socioeconomic populations.

Generalized integral Jensen inequality

Journal of Inequalities and Applications
In this paper we introduce necessary and sufficient conditions for a real-valued function to be preinvex. Some properties of preinvex functions and new versions of Jensen’s integral type inequality in this setting are given.
