Goals
The industrial producer price indices on the non-domestic measure the changes of the industrial producer price levels of the industrial products/services produced in country and sold on the non-domestic market.
Classifications and data publishing
The industrial producer prices on the non-domestic market are collected and processed according to the Classification of Products by Activities (KPD/2015) and the Customs Nomenclature, and the indices are calculated at the level of groups, divisions and sections of the National Classification of Activities (NKD Rev.2).
The industrial producer price indices on the non-domestic market are published by sections and divisions.
The indices cover the sections:
- B (Mining and quarrying),
- C (Manufacturing).
The indices cover the following divisions:
- from section B, divisions 07 (Mining of metal ores) and 08 (Other mining and quarrying),
- from section C, all divisions except division:
18 (Printing and reproduction of recorded media)
19 (Manufacture of coke and refined petroleum products),
33 (Repair and installation of machinery and equipment).
Also published are indices which show the price dynamics according to the final use of the products/services, classified into 3 groups and 2 subgroups:
- intermediate goods except energy,
- capital goods,
- consumer goods:
-- durable goods,
-- non-durable goods.
Data collection
The prices, which are a basis for calculation of the industrial producer price indices on the non-domestic market, are collected with the statistical questionnaire “Monthly report on export prices (Industrial producer prices on the non-domestic market”, (C.izvoz).
The questionnaire C.izvoz is mailed to the enterprises selected in the sample at the beginning of the year.
For each enterprise an individual statistical questionnaire (form) is prepared. The questionnaires include only the representative products/services of selected enterprises. Each selected product/service has a code with 10 digits from the Customs Nomenclature and 2 digits for specification of the product/service, description of the product/service, unit of measurement, and explanation and detailed specification of the price changes.
The enterprises fill in data on monthly average prices of the current month and send the completed forms to the SSO, not later than the 15th of the month, for the previous month.
Prices
The Industrial Producer Price on the non-domestic market is the price at which the producer sells the products/services in the largest quantities, on the non-domestic market, with FOB (free on board) clause, which means that the cost of transport and insurance to the Macedonian border are included in the price. Commercial rebates by the seller are deducted from this price. VAT is also deducted from the price.
The prices in the base period are the basis for comparison of the prices in the current period.
Weighting
For weighting, the turnover on the non-domestic market from the “Annual report on industry” (IND.21), and the value of exports from the “Commodity international exchange”, are used.
The weights are changed every 5 years.
Calculations
-
The monthly industrial producer price indices on the non-domestic market are calculated with the Laspeyres formula.
I/(t/o) - index at the level of group, division, section, main industrial group and total index
P(ti) - price of the product/services "i" in the current month
P (oi) - price of the product /services "i" in the base period
W(oi) - weight of the product/ services "i" in the base period
n - number of products/services
The industrial producer price index on the non-domestic market, at different levels of the National Classification of Activities (total, by main industrial groups, sections, divisions, groups), is calculated in two steps:
- in the first step, the individual indices of each product/service are calculated (at the lowest 10-digit level of the Customs Nomenclature, plus 2 digits of specification), for each individual price, as a ratio between the price of the current month and the base period price; - in the second step, the individual indices of each product/service are compiled by weighting at a higher level (total, by main industrial groups, sections, divisions, groups), while for the calculation of the weights, the turnover on the non-domestic market is used.
(2) Besides the monthly index as a basic one, the following indices are also calculated and published:
- current month index compared to the previous month index,
- current month index compared to the index for December of the previous year,
- current month index compared to the same month index of the previous year,
- average monthly index including current month compared to the same average index of the previous year.
-
Aggregated industrial producer price indices on the non-domestic market according to NKD Rev.2 are also calculated:
- total index,
- indices for 3 main industrial groups and 2 subgroups,
- indices for 2 sections,
- indices for 23 divisions.
