DASP: New Modules and Options in version 2.0

Inequality

IATKINSON 
Estimates the Atkinson indices and their
standard errors taking full account of survey design. 


DIATKINSON 
Estimates the difference between Atkinson
indices and its standard error taking full account of survey design. 
Polarisation

IPOLFW 
Estimates the Foster and Wolfson  FW
(1992) index and its
standard errors taking full account of survey
design. 


DIPOLFW 
Estimates the difference between FW indices and its
standard error taking full account of survey design. 


IPOEGR 
Estimates the Esteban, Gardin and Ray  EGR
(1999) index and its
standard errors taking full account of survey
design. 
Poverty elasticities

EFGTGR

FGTElasticity with respect to growth
in average income (Kakwani (1993)). 


EFGTINEQ

FGTElasticity with respect to Gini
inequality (Kakwani (1993)).

Poverty targeting

ITARGETG

The module itargetg produces
the following estimates and curves for a given list of population groups:

Impact of targeting population
groups on FGT indice

Impact of targeting population
groups on FGT curves (along an axis of poverty lines)

The confridence interval of the
impact of targeting population groups on FGT curves (along an axis of
poverty lines).



ITARGETC

The module itargetc produces
the following estimates and curves for a given list of population groups:

Impact of targeting welfare
components on FGT indice;

Impact of targeting welfare
components on on FGT curves (along an axis of poverty lines);

The confidence interval of
targeting welfare components on FGT curves (along an axis of poverty lines).

Decomposition

DFGTS

The command dfgts decomposes the allevation of FGT
poverty by income components and provides standard errors on elements of the
decompositions. Without any source, the FGT index equals 1. The decomposition is
performed using the Shapley value.

DSGINIS 
Decomposes the Gini index by income sources
with the Shapley approach. 
DPOLAG 
Decomposes the Duclos, Esteban amd Ray
polarization index by population subgroups (Araar (2008) aproach). 


DPOLAS 
Decomposes the Duclos, Esteban amd Ray
polarization index by income components (Araar (2008) aproach).

Curves

CLORENZSM

Produces the following curves with
confidence interval

CFGTSM

Produces the following curves with
confidence interval

Normalised FGT curves;

FGT curves.

CDOMC

Produces the following curve with
confidence interval

CDOMC2D

Produces the difference between the following curve
with confidence interval

Distributive tools

QUINSH

Estimate the income shares and
cumulative income shares by group quantiles (quartiles/quintiles/deciles/etc.).
Graph bar of income shares can be plotted.

Disaggregated data

UNGROUP 
The command ungroup generates
disaggregated data using information on the aggregated data and on the form of
the distribution to be assumed.

Options 

The user can
perform the statistical tests for the
difference between indices, and this, by
adding the option: test(value). For instance,
the user may be interested to test whether the
variation in Gini between two periods is higher,
equals or lower than 0.01;

For the plotted curves by groups, the
correspondent curve at population level is
added.
