This study systematically analyzes the relationship between time preference and age in South Korea, offering policy implications. It reviews the theoretical foundations of age-specific characteristics of time preference and empirically examines time preferences using survey methodology. Findings reveal that time preferences follow a U-shaped pattern with age, reaching their lowest point in the 45-50 age range. Educational attainment significantly impacts time preferences, with college graduates linked to lower preferences and smoother age-related patterns compared to those with high school education or less. Additionally, life insurance policyholders and groups with high financial literacy demonstrate lower and more stable time preferences. These results suggest the need for targeted life-cycle policies. Contrary to traditional economic theory’s view of time preference as a fixed exogenous variable, this study suggests potential endogenous changes, advocating tailored policy approaches in savings, education, finance, and information provision.
