3.1. Data description | |||
Producer Price Index (PPI) is one of the main short-term business indicators; it is regarded as one of the important measures of the economic situation in the Country. Indices for particular economic activity measure the average change in the prices of industrial products, which are produced and sold by Albanian enterprises. Three Producer Price Indices are calculated:
|
|||

The classification used for these statistics is the Statistical Classification of Economic Activities (NACE). The data are produced in national level, breakdown by activity grouped in two digits level of this nomenclature. Till second quarter 2014, the data are produced using NACE Rev.1.1. Starting from second quarter 2014, the data are published in NACE Rev.2. |
|||
3.3. Coverage - sector | |||
Data collection results from the Regulation 1165/98 which was adopted in 1998 and amended in 2005 by Regulation 1185/2005. 1999 – 2014, The data are published at 2-digit level of the NACE Rev.1.1 for: · Mining and quarrying – C: 10 – 14 · Manufacturing – D: 15 – 36 · Electricity, gas, Water supply - E: 40 – 41 2015 till now NACE rev.2 for: · Section B: 05-09 Mining and quarrying · Section C: 10-34 Manufacturing · Section D: 35 Electricity, gas and steam supply · Section E: 36-38 Water supply, sewerage and waste. |
|||
3.4. Statistical concepts and definitions | |||
Producer Price Index measures changes in the level of producer prices of manufactured goods that are produced in Albania and sold by producers on the domestic (Albanian) and/or non-domestic market. The price is the net income earned by the buyer of a product delivered under the terms of the sale. The relative price is the simplest index of the price change in percentage of a product in two given time periods, one of which constitutes the base period. Arithmetically weighted averages of individual observations will form the index numbers. The index (short term- link) for a 6-digit NACE is calculated by multiplying all weights by their corresponding index numbers (price ratio) then divide by the sum of the weights. The annual rate measures the price change between the current quarter and the same quarter of previous year. This measures is responsive to recent changes in price levels but can be influenced by one - off effects in either quarter. Quarterly change measures the price changes between current quarter and previous quarter. Although current, it can be affected by seasonal effects and other effects. |

Data collection is carried out through the Survey on producer prices. From a sample of statistical units are collected the price. Completion of the information is relayed by direct interview by the interviewer with the contact person of the enterprise who is charged to declare the data. |
|||
18.4. Data validation | |||
Verification of prices: Collected prices are compared to their historical trend, price changes for similar products and other knowledge gained by analysts; implausible price changes are verified with the reporting unit. Reporting units verify prices of the products by reporting prices for both the current and the previous month and, if any changes occurred, those changes have to be explained in the questionnaire. In INSTAT, prices have been checked by checking prices on questionnaires, by data entry and by telephone in cases when the questionnaire is not properly completed. |
|||

First step is collecting information from administrative data and telephone interviews. The purpose is to bring this information to the statistic level. This process follows:
|
|||
18.6. Adjustment | |||
Missing prices: In case of a missing price, the price of the previous month is carried forward. Treatment of products out of production: If a product becomes unavailable, an appropriate replacement item is selected with similar specifications. Selection of replacement items: A new item within the product group (CPA 6- digit) is suggested by the respondent and selected. Adjustments for quality differences: Overlap pricing - collection of previous period price of the new item – or judgmental explicit valuation of the specification difference. If none of the two are possible “no price change” is assumed. New Products: New products are included at the end of the year and are part of the sample for the following period. Introducing new products: New products are included as from each new annual link. Seasonal items: The latest observed price is carried forward until the item reappears on the market. Seasonally-adjusted indices: Not compiled. |
