In-flight cardiac arrest is extremely rare, yet catastrophic, and responsible for up to 86% of all deaths in the air. A new comprehensive literature review highlights systemic and policy shortcomings of current aviation safety standards, calling for global alignment. Recommendations include regulated and mandated automated external defibrillators (AEDs) on board, standardized cardiopulmonary resuscitation (CPR) protocols training, and integration of telemedicine. The article in the Canadian Journal of Cardiology, published by Elsevier, aims to inform policy regulators, airlines, and international aviation bodies to improve in-flight medical emergency preparedness and response protocols.

This study explores the profound implications of ambiguity aversion for asset price dynamics and wealth distribution. In a continuous-time macroeconomic model with heterogeneous agents and financial frictions, we demonstrate analytically and numerically that ambiguity aversion leads to a lower risk-free rate, reduced consumption, higher precautionary savings, and wealth redistribution, resulting in significant asset price misalignment. These distortions cause universal welfare loss, making a case for policy intervention. We find that while distortionary capital taxes can mitigate price misalignment, conventional monetary policy, if well-calibrated, can reduce distortions and improve welfare without such trade-offs.

A new large-scale study reveals that uncertainty in climate policy (CPU) is a significant driver for improving corporate Environmental, Social, and Governance (ESG) performance. Analysing data from 4,490 Chinese listed companies (2011-2022), researchers found a strong positive correlation between CPU and ESG scores. The primary motivation is risk mitigation: companies facing higher systemic risk use enhanced ESG performance as a strategic shield. The effect is most pronounced in non-state-owned enterprises, heavy-polluting industries, and highly competitive markets. The findings provide crucial insights for businesses strengthening sustainability strategies and for policymakers aiming to foster resilient, low-carbon economic growth.
