You describe your data clearly, but inevitably I
don't have a clear idea of your research questions
or your research style. I would do lots of graphs
and if I were doing any classical tests I would
want to cross-check with some non-parametric tests
and/or analyses using logarithmic scales for highly
skewed variables. On the latter, you would need
to watch out for zeros.

Thank you for your observation. I have just started
working on summary statistics of the data. I am
working with a merged dataset of household data from
Tanzania (1990-1991 and 1991-92), Vietnam (1991-92,
1997-98) and Guatemala (2000). The dataset includes
variables measuring household characteristics, farm
characteristics, detailed consumption and expenditure
data and community characteristics. These variables
are comparable and consistent across countries and
years.
Given your observation of highly skewed distributions,
I was wondering what kind of summary statistics and
transformed scales would be appropriate?
I would really appreciate any comment or suggestion.
