A first look at this paper suggests to me that the author
mixes up so called "causal indicators" and "effect indicators"
(see: Bollen 1984, and Bollen and Lennox 1991). If I 
remember correctly multiple correspondence analysis is all 
about association between the observed indicators, which 
means that it is a model for effect indicators. However, 
some of the indicators used in the analysis are clear
examples of causal indicators, e.g. the variable
"Does a road pass by the community?" seems to me indicating
a cause of the latent poverty variable rather than being
caused by the latent poverty variable. The problem is that
using the information contained in a causal indicator 
requires a completely different strategy than using the 
information contained in a effect indicator. 

Hope this helps,
Maarten
