SPPI are used as deflators in national accounts and economic comparisons, predictions and analysis.

Classification system

There are mainly the prices of services intended for use by business.

Accuracy and reliability
Overall accuracy

When calculating the SPPI is particularly important to monitor the prices of services with consistent quality. Otherwise, the indexes will be significantly diverted. To identify and eliminate disparities in prices associated with changes in the quality, type or quantity of the selected services are defined by qualitative and quantitative characteristics. When changes in the characteristics of a service or it is not available need to be replaced with a new product from the same group with approximately similar characteristics. The new service should also be representative of the enterprise. Apply various techniques for correction in case of change in quality, in which substitution of the specific service is performed by connecting a simple index of the old and the new service representative.

Sampling error

For SPPIs are not calculated sampling errors due to purposeful sampling technique used. The samples were prefabricated. Cover all businesses with annual turnover above a certain threshold (up 70%). If necessary, the samples are updated annually.

Non-sampling error

Quality control of information and validation of data takes place at the regional level - in territorial statistical offices and national level. Extreme values may be due to faulty data reported by enterprises or change in quality of service observed. These errors are usually tracked easily by comparison with data reported by the same companies from prior periods, adjusted after telephone contact.

Timeliness and punctuality
Timeliness

Services producer price indices are published 60 days after the reporting quarter.

Punctuality

All publications are made timely according publishes calendar data.

Coherence and comparability
Comparability - geographical

Compliance with EU regulations and methodologies for the compilation of SPPI ensure better comparability between the national index and is the basis for obtaining high quality aggregate European indices.

Comparability - over time

Time series published in base 2015 = 100.

Coherence - cross domain

SPPI is internally consistent. Indices of higher levels of aggregation were obtained by weighting the indices by lower levels of aggregation.

Coherence - internal

Comparisons are made with sub-indices of CPI when there is an analogue of the PPI in the services.

Cost and burden

Since the beginning of 2012 NSI started the developing the online information system for data collection, data editing and data processing of STS information. Information system "Short-term statistics" provides more efficient way of collecting data from enterprises. This new system save recourses, reduce the burden of the reporting units and the quality of short term indicators is improved.

Data compilation

Quarterly price indices are calculated by the Laspeyres formula with fixed base, which is changed every five years and is currently 2015. After receiving information from businesses about the prices of representative services are calculated single index for each of them (the price ratio of the price for the current quarter to the average price in the base year). Indices of prices of the different levels of aggregation are obtained as a weighted average by ascending weighting system defined by the structure of the CPA.BG-2008 and NACE.BG-2008. For the formation of weights using information on sales revenue of the observed features in the base year.
