CHANGES
and improvements in the country’s Monthly Integrated
Survey of Selected Industries (MISSI) will be
implemented by 2008, the National Statistics Office (NSO)
said.
The NSO
is currently conducting consultations with the National
Statistical Coordination Board (NSCB) to improve the
data collection and qualifications for survey
participants as well as survey questions.
NSO
Industry and Trade Statistics Department director Estela
de Guzman said NSO will be adding more sample
establishments and questions to the survey to increase
its reliability and make the survey in tune with the
National Income Accounts.
De
Guzman added that along with these changes, the NSO will
be rebasing the MISSI to the 2000 basket. The current
MISSI is based on the 1994 basket.
“We are
already in the process of improving the MISSI. The
weights that we will be using will also be based on year
2000,” she said.
The
changes in the MISSI will also include the new small
industry players in 2007 as well as the big
manufacturing firms.
Last
October, the NSCB and the NSO submitted proposals to the
Bangko Sentral ng Pilipinas to further improve the MISSI
as an indicator of the performance of the manufacturing
sector and as a data source for the national accounts.
The NSCB
Technical Notes on the PSNA Series 2002 second quarter
and third quarter have also provided some explanatory
notes on how the MISSI data are used in the National
Accounts estimation.
Earlier,
users of the MISSI have complained of the survey’s
inconsistencies compared with other government data
sets, saying such effectively confuse rather than give a
clearer picture of plant-level activity.
NSO,
together with the National Statistical Coordination
Board which generates the national income accounts, has
been working with monetary authorities to improve the
reliability of the MISSI data set, which are: the Value
of Production Index (VaPI), the Volume of Production
Index (VoPI), the Producer’s Price Index (PPI) as well
as Capacity Utilization. |
