Producer Price Index slightly declines in September 2018

The Producer Price Index (PPI, 2000=100) for manufacturing dropped at a slower rate of 0.2 percent in September 2018 compared with the 0.5 percent decline in the previous year. This was due to the decreases in the indices of nine major sectors with non-metallic mineral products posting the highest decrease of 11.6 percent followed by furniture and fixtures with a decrease of 7.1 percent. On the other hand, tobacco products (51.8%) led the 11 major sectors that posted increases. Refer to Tables 1 and A-1.

By month, PPI went up by 0.4 percent from the previous month’s rate of 0.1 percent with petroleum products (3.0%) dominating the increase along with other 11 major sectors. Meanwhile, five sectors posted decreases while three sectors reflected flat growth rate. Refer to Tables 1 and A-2.

Sectors are ranked according to their contribution to the overall 2000-based growth rate

Year-on-year growth rates are computed by dividing the current month index by the same month index of the previous year less 1.

Month-on-month growth rates are computed by dividing the current month index by the previous month index less 1.

Introduction

The Philippine Statistics Authority generates various price indices, one of which is the Producer Price Index (PPI). The PPI 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 2018 PPI, the weights of the major sectors and sub-sectors were computed based from the results of the 2014 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:

Note:

Starting with January 2017 PPI, a link factor has been used to adjust weight effects and measure the correct price change.

Industry Coverage

Starting with January 2013 reference month, the PPI utilizes the 2009 Philippine Standard Industrial Classification (PSIC) to classify sectors and industries. Selected industry classes of the 2009 PSIC were grouped to form the 20 industry groupings of the 2018 PPS. These are presented in the table below.
