Title

ceqppp -- Extracts numbers needed for purchasing power parity (PPP) conversion.

Syntax

ceqppp , country(string) baseyear(real) surveyyear(real) [locals]

country(string) Three letter country code (see help wbopendata)

baseyear(real) Base year for PPP conversion (either 2005 or 2011)

surveyyear(real) Year of household survey

locals Store these numbers as locals

Required commands

ceqppp requires installation of wbopendata (Azevedo, 2014). To install, ssc install wbopendata. If not installed, ceqppp automatically installs wbopendata,
assuming there is an internet connection.

Description

ceqppp uses wbopendata (Azevedo, 2014) to extract the three numbers needed to perform
purchasing power parity (PPP) conversions from local currency reported in household surveys to
PPP dollars. It serves two purposes. First, if locals is specified, the needed numbers
are saved in the locals `ppp', `cpibase', and `cpisurvey', which can then be used directly in
other commands from the ceq package that have PPP Conversion options, such as
ceqlorenz, ceqfi, and others. Second, it can be used to quickly confirm that the
numbers used by a country team for the PPP conversion (printed in row 3 of the sheets in the
Master Workbook Part II Output Tables that include a PPP conversion, such as sheets E2, E3,
etc.) match those from World Development Indicators, which ceqppp draws from.

Examples

Brazil with 2009 survey, using 2005 as base year

. ceqppp , country("bra") baseyear(2005) surveyyear(2009) locals

Then the results can be fed directly into another ceq command:

. ceqfi [pw=w] using C:/Output_Tables.xlsx,

hhid(hh_code) psu(psu_var) strata(stra_var)

m(ym) mplusp(ymplusp) n(yn) g(yg) d(yd) c(yc) f(yf)

ppp(`ppp') cpibase(`cpibase') cpisurvey(`cpisurvey')

country("Brazil") surveyyear("2008-2009")

authors("Higgins, Pereira") baseyear(2005)
