Proper quantity indexes for coherent productivity comparisons

Christopher J. O’Donnell

Abstract This paper defines productivity as the ratio of an output quantity to an input quantity. Under this definition, a productivity index is the ratio of an output quantity index to an input quantity index. Coherent productivity comparisons across both time and …

How to Build a Sustainable Productivity Index

Christopher J. O’Donnell

Sustainable production requires that firms produce good outputs in ways that minimise the use of natural capital (e.g. soil and water resources) and the production of bad outputs (e.g. heavy metals, non-biodegradable plastics, greenhouse gases). Statisticians are increasingly being asked to measure …

Agricultural Productivity in Asia

Christopher J. O’Donnell, Antonio Peyrache

Agriculture is a critical part of many Asian economies. This report provides a timely, updated overview of how agricultural productivity has changed over time, via a comprehensive broad-scope analysis across 143 countries, including 18 APO members, using 61 years (1961– 2021) of …

Genome-wide association study and multi-ancestry meta-analysis identify common variants associated with carotid artery intima-media thickness

Devendra Meena, Jian Huang, Marjan Zare, Natalie R. Hasbani et autres

Abstract Carotid artery intima-media thickness (cIMT) is a measurement of subclinical atherosclerosis that predicts future cardiovascular events, including stroke and myocardial infarction. Genome-wide association studies (GWAS) have identified only a fraction of the genetic variants associated with cIMT. We performed the largest …

Using stochastic frontier analysis to assess the performance of public service providers in the presence of demand uncertainty

Hồng Ngọc Nguyễn, Christopher J. O’Donnell

Abstract Public service providers generally make input decisions before the demand for their services is known. To account for demand uncertainty, we divide the decision-making process into two distinct stages: a resource planning stage in which managers choose inputs to meet future …

Determinants of Technical Efficiency of Harumanis Mango Production in Perlis, Malaysia

Khairun Nisaa’ Mohd Nor, Fazleen Abdul Fatah, Christopher J. O’Donnell

The Harumanis mango (Mangifera indica L.) is renowned in Malaysia for its distinctive taste and strong market appeal. Despite the potential for exporting Harumanis mangoes to Japan, productivity in Perlis remains low. This study aims to analyse the determinants of technical efficiency …

Transcriptome-wide association study and Mendelian randomization in pancreatic cancer identifies susceptibility genes and causal relationships with type 2 diabetes and venous thromboembolism

Marcus Tan, Chelsea A. Isom, Yangzi Liu, David‐Alexandre Trégouët et autres

Background Two important questions regarding the genetics of pancreatic adenocarcinoma (PDAC) are 1. Which germline genetic variants influence the incidence of this cancer; and 2. Whether PDAC causally predisposes to associated non-malignant phenotypes, such as type 2 diabetes (T2D) and venous thromboembolism …

Incorporating demand constraints into piecewise frontier models of public service provision

Hồng Ngọc Nguyễn, Christopher J. O’Donnell

Evaluating the performance of public service providers is often complicated by the fact that they must choose input levels before demands for their services are known. We consider an even more complicated situation in which service providers have no opportunity to directly …

Genomics and phenomics of body mass index reveals a complex disease network

D. Saleheen, X. Mai Nguyen, Yan V. Sun, Ítalo Faria do Valle et autres

Elevated body mass index (BMI) is heritable and associated with many health conditions that impact morbidity and mortality. The study of the genetic association of BMI across a broad range of common disease conditions offers the opportunity to extend current knowledge regarding …
