Abstract
Using georeferenced data to map the dramatic flood that hit Bangladesh in August–September 2014, we evaluate how rural households coped with this natural shock. Employing survey data on panel households for the period before and after the shock, we estimate a difference-in-difference model with fixed effects of the impact of flooding on income, expenditure, nutrition, and migration outcomes along the wealth distribution. Our results show that the most affected households experienced significant drops in income and expenditure and an increase in the probability of migrating as a coping strategy to compensate for this loss. Internal migration increased by 7 percentage points for low-wealth households, while international migration increased by 3 percentage points for high-wealth households. Remittances received by poorer households from established international migrants represented significant monetary support after the shock, amounting to approximately 40% of the decline in income from self-employment in farm activities and half the decline in food expenditure.
