Not available. |
|||
10.5. Dissemination format - other | |||
Current data are sent monthly to Eurostat |
|||
10.6. Documentation on methodology | |||
A methodological manual (Producer and import price index, December 2020 = 100, Fundamental principles, Neuchâtel 2021) is available on the FSO Website (https://www.bfs.admin.ch/bfs/en/home/statistics/prices/producer-prices-import-prices.html). |
|||
10.7. Quality management - documentation | |||
Not available. |
|
|||
11.1. Quality assurance | |||
The FSO follows the Code of Practice. |
|||
11.2. Quality management - assessment | |||
Relevance, timeliness and punctuality, comparability and coherence keep largely to the international guidelines. For accuracy and reliability see point 13. |
|
|||
12.1. Relevance - User Needs | |||
The needs of the main users (Swiss National Bank, public administration, research institutes, trade associations and enterprises, Eurostat and OECD) are mostly fullfilled. |
|||
12.2. Relevance - User Satisfaction | |||
Not available. |
|||
12.3. Completeness | |||
See point 3.3 |
|
|||
13.1. Accuracy - overall | |||
As the Producer Price Index is based on target sampling and not random sampling this question cannot be answered. |
|||
13.2. Sampling error | |||
See point 13.1 |
|||
13.3. Non-sampling error | |||
Response rate: The response rate at the time when the survey is closed is usually arout 95%. Actions to speed up or increase the rate of response: Missing responses are followed up by postal and e-mail reminders and telephone contacts. |
|
|||
14.1. Timeliness | |||
Publication date is usually not later than 16 days after the end of the reference month (M+1). The publication schedule is fixed for a calendar year and the data are final when first released and are not subject to revision. Questionnaires are sent out around the 25th of the previous month (M-1). The delay for replies after reception represents about 15 days and data collection closes towards the end of the reference month (M). |
|||
14.2. Punctuality | |||
Almost always delivered in time. |
|
|||
15.1. Comparability - geographical | |||
The same statistical concepts are applied in the entire national territory and no regional breakdown is done. |
|||
15.2. Comparability - over time | |||
The only major break happened in 1993 (completely new methodology, nomenclature and extent). Minor breaks occur at every revision of the index (1939, 1963, 1993, 2003, 2010, 2015, 2020). |
|||
15.3. Coherence - cross domain | |||
Comparisons with industrial output price indices of other countries for a given branch of industry. Price statistics are integrated in the system of National Accounts. Furthermore price indices are used to deflate values of production and turnover. |
|||
15.4. Coherence - internal | |||
All statistical outputs within the data set in question are consistent. There is no annual price update, no chain-linking and no seasonal adjustment. |
|
|||
The data collection and publication of the Producer and Import Price Index occupies six persons to fulfill all requirements (national and international). The burden on respondents is hardly to estimate. |
|
|||
17.1. Data revision - policy | |||
Data are final when first released and are not subject to revision. The same revision policy is applied to STS data released nationally and transmitted to Eurostat. Major methodological changes and revisions are announced in advance through a press release. |
|||
17.2. Data revision - practice | |||
Data are final when first released and are not subject to revision. |
|
|||
18.1. Source data | |||
Type of source: Apart from a statistical survey, a small amount of data is gathered from other sources. Frame on which the source is based: Register of Enterprises and Establishments (REE) Sample or census: Collection of data is carried out through a sample. Criteria for stratification: The stratification is mainly based on relative significance (turnover) and representativeness of the enterprises. But also medium-sized and smaller enterprises should be included in the survey each time. In this case, it is assumed that their prices represent the trend among other medium-sized and small enterprises. Threshold values and percentages: Approximately 10,700 price quotations of producer prices from 2,100 reporting units are collected. Frequency of updating the sample: The sample is updated regularly. |
|||
18.2. Frequency of data collection | |||
Data are collected monthly, bimonthly, quarterly or half-yearly depending on the short-time pattern of price fluctuations of the different product groups. The indices are compiled monthly. |
|||
18.3. Data collection | |||
Questionnaires used in the survey: On the one hand a standard postal questionnaire (containing previous month's data) is used pre-printed with a list of products for which prices are to be given, on the other hand respondents have the opportunity to answer online by means of an eSurvey. Planned changes in national questionnaires: None. Data collection media: Postal or online survey, rarely email. Planned changes in data collection methodology: None. |
|||
18.4. Data validation | |||
Checking of responses and a first set of plausibility tests (where reporting units are asked to provide reasons for large variations [usually more than 15%]) are followed by a second set of plausibility tests (incl. analyzing item indices to ensure that changes are consistent with information about market conditions). |
|||
18.5. Data compilation | |||
Estimates for non-response: Non-response is negligible. If no price can be obtained in most cases the last known price is carried forward. For significant products an estimation is made by using the price development of similar products or of the aggregate of the commodity group. Estimates for grossing-up to population levels: There is no grossing-up. Type of index: Direct Young price index. Small quality changes are not taken into account, while prices are adjusted for substantial quality change, wherever quality difference can be quantified; otherwise products are considered as totally new and linked into the index. When a product becomes unavailable it is replaced by another with similar quality characteristics and sale conditions if possible. New products are regularly selected by the reporting units and linked into the index. Method of weighting and chaining: For the Producer Price Index the sources of weights are the gross production value or, if not available, the turnover as well as the foreign trade statistics. The reference period for the current index weights is 2017/18. Planned changes in production methods: None. |
|||
18.6. Adjustment | |||
No working day or seasonal adjustment is made. Prices quoted in currencies other than the national one are converted into the national currency using the exchange rate at the first working day of the reference month. There are no differences in the practices used for compiling national indices and those used for compiling the indices transmitted to Eurostat. |
