| Summary: | This paper builds on the existing
literature assessing retrospectively the quantitative
effects of natural disasters on different dimensions of
household welfare, to make progress toward the ex ante
identification of households that are vulnerable to poverty
due to natural disasters, especially typhoons. A wind field
model for the Philippines is employed to estimate local wind
speeds at any locality where a tropical typhoon directly
passes over or nearby. The estimated wind speeds are merged
with the household Family Income and Expenditure Surveys at
the barangay level, and consumption expenditures are then
regressed against wind speed (or a related damage index) and
household socioeconomic characteristics. The estimated
coefficients from the regression model are then used to
estimate ex ante household vulnerability to poverty (the
likelihood that household consumption falls below the
poverty line) in the event of future natural disasters of
different intensities. |
