Resumen
Descripción
Measuring poverty requires adjusting
nominal consumption (or income) into a real value of
consumption, across geographic areas and over time. To this
end, data on consumer prices are used to construct a price
index. There are a range of approaches to do this, from
using the consumer price index, to survey-based unit values,
which differ in the underlying sources of price data and
methodologies for indexing. These different approaches can
have large impacts on poverty measures and trends.
Surprisingly little attention has been focused on this
topic. This study reviews a range of issues and the evidence
on how prices matter for measuring poverty, particularly in
Africa. It draws on a wide literature, much from developed
countries, and offers suggestions for future work in this area.
