Study links childhood Korean War exposure to larger job cuts by CEOs
A study linked childhood Korean War exposure to tougher staffing decisions by CEOs of South Korean companies.
Researchers examined 24,703 financial records from listed companies between 2002 and 2023.
CEOs who experienced the war as children tended to increase hiring less during periods of rising sales.
In downturns, their companies cut 106% more jobs than companies led by other CEOs.
The pattern was strongest among those who experienced the war between ages 4 and 15, and it was linked to civilian deaths in the areas where they grew up.
The findings suggest early hardship can shape risk decisions decades later, though they show a relationship rather than proving that war exposure caused the decisions.
The research does not describe any next steps.

What people are saying
Exposure to war in childhood can heighten sensitivity to negative risks.
War is an extreme environment characterized by uncertainty, loss and a lack of resources, and exposure to such instability during childhood can affect how people recognize threats and make decisions under pressure later in life.
Experiences during childhood can have a lasting influence on managerial decisions decades later.
Other serious experiences during childhood may also have lasting effects on how leaders perceive risk and make decisions later in life.
