Purpose – The study aims to analyze the role of coronavirus testing capacity to possibly reduce the case
fatality ratio (CFR) in a large cross-section of countries. The study controlled health-care expenditures,
logistics performance index (LPI), carbon damages, and corporate social responsibility (CSR) to
understand the nature of causation between the CFR and stated factors.
Design/methodology/approach – The study used a cross-sectional regression apparatus for coefficient
estimates and variance decomposition analysis (VDA) for forecasting relationships between the variables
over time.
Findings – The results confirmed the W-shaped relationship between CFR and case-to-test ratio (CTR) in
the presence of a LPI that exacerbates the CFR cases across countries. The VDA estimates suggest that
carbon damages, logistics activities, and CSR are likely to influence CFR over time.
Originality/value – To the best of the authors’ knowledge, the study is believed to be the first study that
assesses the W-shaped relationship between the CFR and CTR in the presence of dynamic variables,
which helps to formulate long-term sustainable health-care policies worldwide
