Article
Full-text available
This article reveals the extent of international inequalities in the immediate impact of the COVID-19 pandemic on participation in paid work. Drawing on World Systems Theory (WST) and a novel quasi-experimental analysis of nationally representative household panel surveys across 20 countries, the study finds a much sharper increase in the likelihoo...
Article
Full-text available
A small, but growing, body of empirical evidence shows that the material and persistent variation in many aspects of the performance of healthcare organisations can be related to variation in their management practices. This study uses public data on hospital patient mortality outcomes, the Summary Hospital-level Mortality Indicator (SHMI) to exten...
Conference Paper
Full-text available
A feature of public sector organisations is the presence of substantial variations in productivity. What drives organisational productivity and its persistence? Using a rich panel on NHS hospitals in England, we trace the variation in productivity back to differences in clusters of complementary management practices. We introduce the indeterminacy...
Preprint
Full-text available
Delayed discharges of patients from hospitals, also known as bed--blocking is a long standing policy concern. Such delays can increase hospital treatment costs and may also lead to poorer patient health and experience. Prior research indicates that external factors, such as, greater availability and better affordability of long term care associated...
Article
Full-text available
Variation in the performance of providers across healthcare systems is pervasive. It is recognised as both a major concern and an opportunity for learning and improvement. Variation between providers is broadly considered to be due to management practices and contextual factors such as catchment-area demographics. However, there is little understan...
Article
Full-text available
A major feature of health‐care systems is substantial variation in hospital productivity. Hospital productivity varies widely across countries. The presence of such variation suggests potential areas for improvement, which can substantially lower health‐care costs. This research aims to investigate factors that may explain variations in hospital pr...
Article
Full-text available
A major feature of health care systems is substantial variation in health care quality across hospitals. The quality of stroke care widely varies across NHS hospitals. We investigate factors that may explain variations in health care quality using measures of quality of stroke care. We combine NHS trust data from the National Sentinel Stroke Audit...
Conference Paper
Full-text available
Substantial research has been carried out to explain the effects of economic variables on obesity, typically considering only a few factors at a time, using parametric linear regression models. Recent studies have made a significant contribution by examining economic factors affecting body weight using the Behavioral Risk Factor Surveillance System...

Question
I have query regarding pharmaceutical data.
As part of my PhD in Health Economics I am interested in research questions such as impact of mergers, competition etc. on pharmaceutical industry or firm innovation lets say.
Could you please suggest me where I can access firm specific pharmaceutical data to address the above type of research questions? Thank you Manhal

Hi,
I was looking for some key articles for example well cited ones on the primary determinants of outside or ambient air pollution of cities worldwide. Are you aware of any such articles?
Any help will be much appreciated.
Thank you.
Question
I am new into Machine Learning so please excuse me if my question is naive.
My question is, is it possible to use trees for example rpart or ctree after variable selection procedures such as Lasso/Random Forest to study the interactions amongst the variables? Are there any published academic articles on this?
