.: Hierarchical Bayes Multivariate Estimation of Poverty Rates based  
on Increasing Thresholds for Small Domains :.

Abstract.
The aim of this work is to propose a  model-based small area method  
for calculating estimates of poverty rates based on different  
thresholds for subsets of the Italian population (domains) obtained by  
cross-classifying by household type and administrative region. The  
suggested estimators satisfy the following coherence properties: i)  
within a given area, rates associated with increasing thresholds  
should also be monotonically increasing; ii) interval estimators  
should have lower and upper bounds within the interval (0,1); iii)  
when a large domain-specific sample is available the small area  
estimate should be reasonably close to the one obtained using standard  
design-based methods; iv) estimates of poverty rates should also be  
produced for domains for which we have no sample or when no poor  
households are included into the sample.  We adopt a Hierarchical  
Bayesian approach to estimation where posterior distributions are  
approximated by means of MCMC computation methods. Empirical analyses  
are based on data from the 2005 wave of the EU-SILC survey.
