摘要:We propose a new methodology for comparing poverty over multiple periods across
time and space that does not arbitrarily aggregate income over various years or
rely on arbitrarily specified poverty lines or poverty indices. Following Duclos
et al. (2006a), we use the multivariate stochastic dominance methodology to
create dominance surfaces for different time spans. We elaborate the method
first for the bidimensional case, using as dimensions income observed over two
periods: one at the beginning and one at the end of a time span. Subsequently,
we extend it to the case where incomes are observed over n-periods. We
illustrate our approach by performing poverty comparisons using data for
Indonesia and Peru.
