Calculating persistent poverty

Dear Team,
I need to estimate persistent poverty rates following the standard definition that someone is persistently poor if she/he has been poor in the current year and in two of the last three years. The first question I have is regarding attrition: if the poor were more prone to attrition, are the longitudinal weights able to account for that? And my second question is about balanced panels: if I keep only those with income data in the last 4 waves, would I be affecting the representativeness of the sample?
Thanks a lot for your support,

Dear Facundo,

Thank you for your question.
Yes, the weights account for attrition, including that related to income.
If you use imputed income you don't need additional correction. If you use reported income (excluding imputation) you may want to consider correcting for missingness in income through either imputation or additional weighting (imputation may be preferable here as you know many other attributes of those people with missing income).

Hope this helps,
