PHL-PSA-PPS-2013-v2.1
The Philippine Statistics Authority generates various establishment based price indices and one of these is the Producers Price Index.
The 2013 PPI (2000 base year) is generated from the results of the Producer Price Survey conducted monthly by the PSA. This is done through the collection of actual producer prices from sample establishments nationwide. The PPS uses a shuttle type questionnaire which provides the respondent establishments with a running account of all monthly responses for the year. For 2013, the survey covered 595 sample products produced by 309 manufacturing establishments.
The Producer Price Index (PPI) for Manufacturing is a composite figure of producers prices of representative commodities included in the market basket. The PPI serves various purposes, the most important of which are the following:
a. measures monthly or yearly changes in the producers prices of key commodities in the manufacturing sector
b. serves as deflator to Value of Production Index (VAPI) in the estimation of Volume of Production Index (VOPI)
c. serves as deflator in the estimation of manufacturing production in real terms (at constant prices) in the system of national accounts.
The PPI is computed using the Paasche-type method of index computation . As such, the weights are continously revised upon availability of the latest data from the annual survey or census. In the case of 2013 PPI, the weights are taken from the 2010 Annual Survey of Philippine Business and Industry (ASPBI). The revision of weights , are however instituted at the beginning of each year and are used for the entire year.

Sampling
The 2013 PPS is a non-probability sampling survey of the manufacturing sector. Sample establishments and commodities were selected using the following criteria:
a. the commodity has a relatively high market share
b. the commodity was available in the market in 2000, this being the base year
c. the commodity is being produced currently, and
d. the market share of the commodity has been stable for the last 3 years
In the same manner, criteria were also set for the selection of establishments, as follows:
a. establishment has an average total employemeny of 50 and over
b. establishment has relatively high concentration ratio
c. establishment is good respondent in past and current surveys of PSA; that is, it submits prompt reports and provides quality data
d. preferably, the establishment is a sample of the MISSI.
The 2013 PPS utilizes the 3-digit and selected 4-digit ammended PSIC as its industry domain which is patterned after ISIC version 3.

Face-to-face [f2f]
The distribution and collection of questionnaires is under the supervision of the Provincial and Regional Offices.
The PPS went through the clearance process of the National Statistical Coordination Board (NSCB). It utilizes a shuttle type questionnaire with NSCB approval number and expiration date. For the 2013 PPS, the NSCB approval number is NSO-0714-01 with expiration date of March 2014.
The field offices distribute the questionnaires at the beginning of the year and collects the data on a monthly basis.

Data Processing
It is important to verify the reasonableness and reliability of the prices of products included in the market basket for a given month. Data editing consisted of three stages: field editing, office verification and machine validation.
Field editing of data was done by the provincial staff upon collection of the accomplished questionnaires from the establishments. The objective is to check for completeness and consistency of entries in the questionnaires. Any inconsistent or missing data was corrected at this stage as this can be immediately verified from the respondents.
Office verification was done by provincial office staff upon receipt of the accomplished questionnaires from the field men. In some instances, callback to the establishments in the form of phone call or email to verify some inconsistent or missing data is done.
Desk verification was done by the ISD staff to check the consistency and reasonableness of entries in the accomplished questionnaires. This process also validates the status of establishments such as non-responding and reported closed, cannot be located, transferred, and out of scope. The telephone was extensively utilized to verify information from the establishment's contact person. The Internet was also used to obtain information on the contact address and to research for information on the status of the establishment.
For unit or item non-response, the following are undertaken:
1. Establishments that stopped operation, temporary out of business (TOB), strike, etc., during the year, historical imputation without trend adjustment or the use of the latest available data of the establishment. This method is appropriate for the reason that the prices of a number of products/commodities do not change very much over a short period of time.
2. Imputed values are revised upon receipt of actual data for inclusion in the revised indices.

Data Appraisal
The quality of the PPI indicators are measured in terms of the following:
> Representativeness of the samples as measured in the CONCENTRATION RATIO- the combined production value of the samples as a percentage to the total industry production value
> Response rate of the survey
> Imputation method used for non-responses
> Representativeness of the samples as measured in the CONCENTRATION RATIO- the combined production value of the samples as a percentage to the total industry production value
