This is a working paper.
During the COVID-19 pandemic, the Japanese government provided special cash payments (SCPs) multiple times. This study aims to estimate the marginal propensity to consume (MPC) to these income shocks using detailed bank transaction data. Our findings indicate that the MPC is stable at around 0.2 for both the first wave of SCPs launched in mid-2020 and the second wave of SCPs provided from the end of 2021 to the beginning of 2022. The MPC varies depending on an individual's wealth and liquidity constraints. Specifically, the MPC tends to increase as individuals become less wealthy and more liquidity constrained.
