Childhood exposure to the Second World War and financial risk taking in adult life

Abstract

Adverse childhood experiences might have long-lasting effects on decisions under uncertainty in adult life. Merging the European Survey on Health, Ageing and Retirement with data on conflict events during the Second World War, and relying on region-by-cohort variation in war exposure, we show that warfare exposure during childhood is associated with lower financial risk taking in later life. Individuals who experienced war episodes as children hold lessand are less likely to holdstocks, but are more likely to hold life insurance, compared to non-exposed individuals. Effects are robust to the inclusion of potential mediating factors, and are tested for nonlinearity and heterogeneity. Moreover, we provide evidence of hedonic adaptation to war, as high and low intensity of war exposure have comparable long-term effects. We also document that war exposure in childhood increases sensitivity to financial uncertainty since exposed-to-war individuals are less likely to hold stocks after periods of high volatility. Finally, we shed light on the most likely mechanism in the relationship between war exposure and financial risk takingi.e., enhanced sensitivity to uncertaintyand we show that preferences, and not beliefs, channel this relationship. ☆ We thank Compagnia di San Paolo (Turin) for the financial support to the project 'InsideTrust' (PI: P.

Growing up in the Iran–Iraq war and preferences for strong defense

“…Can we also see a similar relationship with support of strong defense as in the case of the impressionable years for other age cohorts? This analysis is motivated by findings of Bellucci et al (2019) who argue that exposure to warfare in early life shapes human capital outcomes in later life and has a long-term impact on social preferences.…”

Factors Influencing Financial Risk Tolerance: A Review

“…The investigation indicated significant positive impacts of investment behaviours, for instance, years of investment experience as well as the type of investors to trading frequency during the pandemic. In addition, a study by Bellucci et. al (2020) also examined the social crisis impact on FRT.…”

Scarred but Wiser: World War 2'S COVID Legacy

“…A study based on a representative sample of adults from 14 European countries demonstrates that early-life exposure to WW2 increases individual resilience and optimism about life, leading to a higher probability of survival (Arpino et al 2019). Bellucci et al (2020) use the European Survey on Health, Ageing, and Retirement to show that war-exposed individuals have higher resilience to shocks and increased perception of uncertainty and uncontrollability of the environment. Cassar et al (2013) explore the effects of war-related violence on trust and cooperation in Tajikistan and found that exposure to war enhanced prosocial behavior.…”
