Rural poverty rankings of Indian states in 1990 were very different fr
om those of 1960. This unevenness in progress allows us to study the c
auses of poverty in a developing rural economy. We model the evolution
of various poverty measures using pooled state-level data for the per
iod 1957-91. Differences in trend rates of poverty reduction are attri
buted to differing growth rates of farm yield per acre and differing i
nitial conditions; states starting with better infrastructure and huma
n resources saw significantly higher long-term rates of poverty reduct
ion. Deviations from trend are attributed to inflation (which hurt the
poor in the short term) and shocks to farm and non-farm output.
