Evaluating the Performance of Variants of the Lee-Carter Method for Mortality Forecasting in the Population Projection of the Czech Republic from the Czech Statistical Office 2023–2100

Demografie
This article discusses the use of the Lee-Carter model, one of the most widely used methods for mortality forecasting. It also discusses its modified versions, namely the cohort and coherent variants, which were developed to improve the forecast accuracy

Application of Machine Learning to Mortality Modeling and Forecasting

Risks, 2019
Estimation of future mortality rates still plays a central role among life insurers in pricing their products and managing longevity risk. In the literature on mortality modeling, a wide number of stochastic models have been proposed, most of them ...

Association and heterogeneity of insured lifetimes in the Lee–Carter framework

Scandinavian Actuarial Journal, 2007
This paper is devoted to the study of some unexpected consequences of the Lee-Carter model for mortality projection. The fact that survival probabilities are governed by a stochastic process induces some positive dependence between insured lifetimes (namely, association).

Drivers of Scope 3 Emissions Disclosure Quality—CDP Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT Scope 3 emissions account for a significant portion of a supply chain's carbon footprint, yet very little research explores the key drivers of high‐quality Scope 3 disclosures. Additionally, while climate governance is a vital part of both improving carbon performance and ensuring corporate accountability, its broader impact on disclosure ...

Riding on a Pegasus: Is ‘Sustainability’ Still a Myth in Bangladesh's RMG Sector?

Business Strategy and the Environment, EarlyView.
ABSTRACT Although a growing number of studies explore sustainability, the role of stakeholders and institutions in shaping environmental sustainability initiatives remains overlooked particularly from the upstream fashion supply chain contexts. Drawing upon the framework proposed by Lee, our study aims to fill this gap by examining the interplay ...

Physics-Informed Neural Mortality: Embedding Biological Mortality Laws in Neural Differential Equations for Life-Table Closure and Longevity Uncertainty Quantification

Mathematics
Deep learning has become the default toolkit for mortality forecasting, yet essentially all existing models are purely data-driven: they fit well in-sample but can produce biologically implausible surfaces and extrapolate poorly to the oldest ages, and ...

Water‐Conscious Governance: The Role of Co‐Opted Members in Water Withdrawal

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the impact of co‐opted board directors on water withdrawal. Based on a U.S. sample of 4194 firm‐year observations between 2008 and 2022, we find that the presence, independence and tenure of co‐opted directors reduce firm water withdrawals.

Transformation Teams Leading the Hispanic‐Serving Institutions Movement at HSI Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT The Department of Education defunded discretionary grant programs for enrollment‐based minority‐serving institutions (MSIs) on September 10, 2025, yet Hispanic‐serving institutions (HSIs) still exist and must continue to adapt to their growing population of Latine/x students.

Examining structural shifts in mortality using the Lee-Carter method [PDF]

We present an extension of the Lee-Carter method of modeling mortality to examine structural shifts in trajectories of mortality. Austrian data consisting of 53 years of single-age mortality rates are subdivided into 30 24-year submatrices.

A Multilevel Framework of Employee Environmental Initiatives: The Role of Departmental Climate, Departmental Management's Green Leadership, and Corporate Environmental Responsibility

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study develops a multilevel framework to examine how employees' discretionary environmental initiatives are shaped by organizational and departmental contexts. Using survey data from 150 employees across 25 organizations, we integrate organizational climate and leadership theories to investigate the effects of Corporate Environmental ...
