Adan, thanks for sharing your paper. I don't have an economics background, so apologies if this should be obvious from your paper. Your paper presents the implication that husbands and wives will not report asset data in the same way. Was any of your analysis able to suggest whether men or women presented a more accurate picture? I know one of the strong recommendations of the use of the PPI is that you conduct this interview at the household so that you can also verify at least the asset-ownership questions (so seems future research should also consider how to match up husband vs. wives reporting with who provided more truthful information--by validating actual ownership). Would love to hear more on this if any of your data can shed light on it?
