Analysing data from one of the most intensive regional bombing campaigns in history during the Vietnam War and six national census waves, I identify a U-shaped pattern in the causal relationships using an instrumental variable. These findings indicate that individuals with wartime exposure initially contribute less to public labour obligations. Their contributions increase when they endure high-intensity regional bombings. This pattern is particularly evident in Northern Vietnam, rural regions, and among people born before 1975. The findings make a novel contribution to our understanding of the long-term effects of early-life adversities on public service activities.
