Quality Description of Producer Price Index for Services

1. Relevance of statistical information

1.1 A summary of the information content and purpose of use of the statistics

Producer Price Index for Services describes the price development in business services provided by enterprises to other enterprises and the public sector. The index describes the relative change in prices compared to a certain base period.

The Producer Price Index for Services is compiled on product basis. The index describes development in the prices of certain types of services irrespective of the main industry of the producing enterprise. If a service enterprise also produces goods, its goods production is excluded from the scope of the Producer Price Index for Services. On the other hand, an enterprise that mainly produces industrial goods may also produce services in which case its services production is included in scope of the description of the Producer Price Index for Services.

One of the key purposes of the Producer Price Index for Services is to function as a deflator in national accounts calculations. With it the value of production or sales is converted to volume of production. Enterprises can use the data of the Producer Price Index for Services when comparing the price development of their purchases or sales with the average development of the industry.

1.2 Information source and classifications used

1.2.1 Information source

As a rule, price data for the Producer Price Indices for Services are collected from enterprises quarterly. Besides the data collected from enterprises, price data or point figures from Statistics Finland’s other statistics are also exploited in the compilation of the Producer Price Indices for Services.

1.2.2 Classifications

The industrial classification used in the compilation is the Finnish Standard Industrial Classification TOL 2008, which has been confirmed by Statistics Finland and is based on NACE Rev. 2., the industrial classification of the European Union. As far as appropriate, the services of specific industries are classified into main groups according to the CPA product classification, which is the European Union’s classification of goods and services by activity. Where necessary, detailed product classifications are used within the individual service product categories of the CPA.

1.3 Laws and regulations

The production of the statistics is based on the Statistics Act (280/2004) and on a Council Regulation (EC) concerning short-term statistics (No 1165/1998 and No 1158/2005). Only the data necessary for the calculation of the index but not available from another source are collected from data suppliers. Confidentiality is taken into account when releasing the data; it is not possible to identify from the results information or development concerning an individual enterprise.

2. Methodological description of survey

2.1. Compilation of the index

Statistics Finland’s Business Register is used as the sampling frame for the Producer Price Indices for Services. In addition, Business Services Statistics is used in some cases. The Business Register contains data on the industry and turnover of enterprises. The Business Services Statistics describe the structure of turnover and services produced in certain branches of industry providing business services. The indices have been developed independently for individual service industries, which is why the used sampling method varies by industry. Depending on the industry, the data suppliers have been selected either by PPS (Probability Proportional to Size) sampling, judicious sampling or by combining judicious sampling and probability-based sampling. The services for the price monitoring have been selected in co-operation with service enterprises.

The Laspeyres price index formula is used in calculating the index. Geometric averages of price ratios calculated from the prices of individual service products are combined into indices for the main product groups of an enterprise, and then weighted into its overall index using a specific coefficient for each main group. The weighting coefficients are based on enterprises’ turnover and its distribution between the main groups of the enterprise. The turnover figures used in the weighting are either obtained from the data reported by the enterprises themselves or from Statistics Finland’s Business Register, and figures should represent only the turnover that stems from a certain industry.

The overall index is calculated by means of industry indices. The weights between different industries are based on national accounts data on the use of enterprises’ and the public sector’s services. The weight structure corresponds to the values of 2010.

Further information about compiling the Producer Price Indices for Services is available in the Methodological descriptions of the statistic.

2.2. Development and publication of new indices

Statistics Finland will enlarge the coverage of total index by developing indices for new services industries. Publication of new indices can commence once data concerning an industry have been collected from an adequately large number of enterprises for at least twelve months and once it has been verified that index figures depicting average price development in the industry can be sufficiently reliably calculated from the prices provided by the data suppliers.

The development of Producer Price Index for Services was started in 2000, and indices for new service industries are being devised continuously. In connection with the 2010=100 renewal, industries Passenger rail transport, interur-ban (TOL 2008: 491), Food and beverage service activities (TOL 2008: 56), Real estate agencies (TOL 2008: 6831), Education (TOL 2008: 85), Human health activities (TOL 2008: 86), Creative, arts and entertainment activities (TOL 2008: 90), Sports activities and amusement and recreation activities (TOL 2008: 93) and Repair of computers and personal and household goods (TOL 2008: 95) were included to the index.

The total index currently covers about 60 per cent of the market services. The service industries excluded from the overall index are wholesale and retail trade activities and financial and insurance activities.

3. Correctness and accuracy of data

The Producer Price Index for Services is calculated on the basis of over 17,500 prices collected from approximately 360 data suppliers. The number of prices and data suppliers varies by industry. Roughly 15,000 of price data concern the rents of office and business premises. The Producer Price Index for Services describes the relative change in prices compared to a certain base period.

4. Timeliness and promptness of published data

Indices are published on the 24th day or the weekday following it of the month following the end of the statistical reference quarter.

Depending on the industry, the time of collecting price data from enterprises may be the first, second or third month of the quarter under review. In some cases real charged unit prices are collected for the whole quarter under review.

5. Accessibility and transparency/clarity of data

Producer Price Indices for Services is a quarterly statistics. Indices are published on the 24th day or the weekday following it of the month following the end of the statistical reference quarter at 9 a.m.

6. Comparability of statistics

7. Coherence and consistency/uniformity
