Is Subjective Well‐Being Insured Against Income Shocks? Evidence From 20‐Year Panel Data in South Korea
利用韩国20年面板数据，研究发现永久性收入冲击显著影响生活满意度，而暂时性冲击影响很小；外部因素（如家庭收入、休闲）相关的满意度对收入冲击更敏感。
ABSTRACT Using 20 years of nationally representative panel data in South Korea, we estimate how life satisfaction responds to income shocks. We document that unexpected income changes significantly impact an individual's life satisfaction, and the magnitudes depend on the persistence of income shocks. We find that permanent income shocks substantially penetrate life satisfaction, while transitory income shocks have minimal impact. We also find that life satisfaction regarding external factors such as family income and leisure activities is more sensitive to income shocks than life satisfaction related to social relationships. Our findings imply that it is critical for the government to address persistent income losses in the economy (e.g., long‐term unemployment driven by skill‐biased technological changes or work‐limiting disability) as a means to improving social welfare.
