• ·  Technical Notes
• The National Statistics Office generates various price indices, one of this is the Producer Price Index. (PPI). The PPI is generated through the results of the Producers Price Survey (PPS) conducted nationwide. The survey gathers monthly actual producer prices of selected products included in the market basket.
• PPI utilizes the Paasche-type method of index computation with weights computed from the production concentration ratio of the Census of Philippine Business and Industry (CPBI)/ Annual Survey of Philippine Business and Industry (ASPBI). The weights are updated as soon as new results of the ASPBI/CPBI are available and applied at the beginning of each survey year.
• Hence, the weights of the major sectors and sub-sectors for the 2009 PPI were computed from the results of the 2006 CPBI for Manufacturing Establishments of total employment of 20 and over, which is the latest census results. The 2010 PPI still uses the same weights.
• Moreover, for industry classification, the 2010 PPI utilizes the amended 1994 Philippine Standard Industry Classification. Rubber and Plastic Products is a new major sector, beginning the 2008 PPI, consisting of two sub-sectors, namely: Rubber Products and Plastic Products. Rubber Products was previously a major sector while Plastic Products was one of the sub-sectors of Chemical Products.
• Previously, with seven sub-sectors, the major sector of Chemical Products now has six sub-sectors, namely: Basic Chemical and Industrial Gases, Fertilizers, Paints, Drugs and Medicines, Cosmetics and Toilet Preparations and Miscellaneous Chemicals.
• Non-responding sample establishments are estimated using cold-deck imputation method. Revisions to the preliminary estimates are done upon receipt of actual reports from late respondents.
