Longer life expectancy and insufficient savings expose individuals to financial vulnerability in older ages and prompt government support measures. We study a government subsidy program for the low-income elderly population in Singapore. Using comprehensive, high-frequency transaction data, we estimate a marginal propensity to consume (MPC) out of the permanent income increases of 0.7, driven by precautionary savings and bequest motives. More liquidity-constrained recipients exhibit an MPC of 1. We find no evidence of labor supply reduction or other strategic behaviors. We discuss implications for eligibility criteria, payment frequency, and distribution form in policy design.
