  •    Producer Price Index decrease slowly in September 2014

Producer Price Index (PPI, 2000=100) for manufacturing slowly moved down by 1.2 percent in September 2014 compared with negative 6.8 percent in September 2013. The downtick can be traced to the negative growth of seven sectors led by chemical products (-22.0%). On the other hand, the increases registered by thirteen major sectors led by tobacco products (11.4%) were not able to improve the overall year-on-year performance of the September 2014 PPI. Refer to Tables 1 and A-1.

On a monthly basis, PPI decelerated to -1.2 percent in September 2014. The downtrend can be attributed to the decrements of four major sectors led by chemical products (-25.3%). In addition, the decreases posted by the two heavily weighted sectors: petroleum products (-1.2%) and food manufacturing (-0.8%) contributed to the negative performance of the monthly PPI. Meanwhile, 13 sectors reflected increases while three posted flat growths. Refer to Tables 1 and A-2

Technical Notes
  • Introduction
The National Statistics Office generates various price indices, one of these is the Producer Price Index (PPI). The PPI, a designated statistics, is generated through the results of the Producer Price Survey (PPS) conducted nationwide. The survey gathers monthly producer prices of selected products of establishments included in the market basket.
 
The PPI is used as a deflator of the Monthly Integrated Survey of Selected Industries (MISSI) to derive indicators for the Volume of Production Index (VoPI) and Volume of Net Sales (VoNSI).
 
  • Method of Index Computation
PPI utilizes the Paasche-type method of index computation. The weights are computed from the value of production to derive concentration ratios from the Census of Philippine Business and Industry (CPBI) or Annual Survey of Philippine Business and Industry (ASPBI). The weights are updated as soon as new results of the ASPBI or CPBI are available and applied at the beginning of each survey year.
 
For the 2014 PPI, the weights of the major sectors and sub-sectors were computed from the results of the 2010 ASPBI for Manufacturing Establishments with total employment of 20 and over, which is the latest survey results.
 
The formulas in the computation of the PPI are as follows:
 
 

 

  • Industry Coverage

Starting with January 2013 reference month, the PPI utilizes the 2009 Philippine Standard Industry Classification (PSIC) to classify sectors and industries. Selected industry classes of the 2009 PSIC were grouped to form the 20 industry groupings of the 2014 PPS. These are presented in the table below.

  • Response Rate

The response rate for September 2014 is 91.3 percent, which corresponds to the retrieval of 326 establishments’ reports out of the 358 samples for the survey.  Refer to Table B.
