Measuring chronic poverty without a panel

A new method of decomposing cross-sectional poverty estimates into chronic and transient components is demonstrated using data from a recent household survey in Papua New Guinea. This method is simpler than previously used pa nel methods because it does not require data on every household in every pe riod. The only requirement is that a subset of the surveyed households have a repeat observation made on their welfare indicator some time after the i nitial observation. In the setting considered, the chronic and transient co mponents of headcount poverty are roughly equal, while three-quarters of th e mean poverty gap is transient-in the sense of being due to within-year fl uctuations in expenditures.
