IPA 2009 Multi-beneficiary StatisticalCooperation Programmeexhaustively (6 128) enterprises or 11.6 percent of the sampling frame and theinformation is collected by face to face interviews. Survey non response rate is 10.1percent according to the number of units.All cases of non-contact; full refuse and partial refuse (for different tables andindicators) are considered as non- response or missing data.The treatment of partial non-response is done by using direct methods or theircombinations such as study of time series data of enterprise and branch; data frombalance-sheet file (profit and loss accounts); the information from other filesavailable in INSTAT such as business register, VAT file, file of production priceindex, average data of branch where the enterprise is included are analyzed and used,data from enterprises that have similar conditions are used and method of averagestructure, especially for expenditures, is usedImputation is done to cover the non-response of large enterprises. It is based on threemethods: historical trend imputation for units with data from previous year in profitand loss account or in business register or in other surveys conducted by INSTAT;cold deck with use of the previous year administrative data for units for which wehave data from administrative sources; mean value imputation for the rest of theresponsive large enterprises in the respective stratum. For the part left untreated reweightinessmethod is used.Variables used for grossing-up to the population are the weights for the turnoverindex, based on the turnover from the SBS statistics for the reference year 2006Initial weight of enterprise in the stratum is estimated P (i) initial = Ni / niWhere: Ni is the total number of enterprises in the stratum ini is the number of sample enterprises in stratum iNote: For the purpose of GDP estimations only individual data for each enterpriseare used.Other statistical surveys (retail trade, producer’s price indices, construction costindex, consumers’ price index and short term survey) carried out by INSTAT are notused in calculation of indicators at current prices by production approach. Thesesurveys are used for calculation of indicators at constant prices (producer’s priceindices, construction cost index and consumers’ price index), quarterly indicators(short term survey) and indicators by expenditure approach (retail trade). Thesesurveys are mentioned in more details in next Chapters.34/236
IPA 2009 Multi-beneficiary StatisticalCooperation Programme3.2 ValuationIn accordance with the basic accounting principle, data in annual accountingstatements which are used for the estimation of output and intermediate consumptioncomponents are on accrual basic and administrative sources which are on cash basicand therefore several adjustments are necessary in transfer from cash to accrual data.In principle output is valued at basic prices and this includes subsidies on products.Changes in inventories are not adjusted for any holding gains at industry level and bytype of inventory. All products included on intermediate consumption are valued atpurchasers’ prices.Output of market producer is measured as the sum of sales, changes in inventories offinished goods and work in progress, the value of products which are produced forown final use and with the value of subsidies on products. Changes in inventories offinished goods, goods for own final consumption and work in progress are measuredaccording to input costs. Goods for resale are valued at purchasers’ prices.Trade margin as trade output is estimated as the difference between total sales oftrade goods less the purchase value of sold goods for resaleIntermediate consumption products are at purchasers’ price. Uses of intermediategoods are usually estimated with purchases in the period plus withdrawals frominventories less increases of inventories.The main taxes on products are estimated with direct data sources on cash basis.VAT is estimated by monthly VAT reports submitted by the Tax Administration andannual data from Ministry of Finances. Import duties and taxes on import areestimated from customs statement. All excise duties due to payment by type ofexcise are shown in monthly reports by the Customs Administration as well as inannual data of budget statistics from Ministry of Finances. Subsidies on products areaccording to the budget statistics valued as accrual transactions in the period.3.3 Transition from private accounting and administrative concepts to ESA95national accounts conceptsTransition from private accounting and administrative concept to ESA95 nationalaccounts concepts is an important part of national accounts compilation andparticularly of GDP by the production approach. The estimation of GDP byproduction approach mostly depends on accounting statements’ data (profit and lossaccounts) as well as on annual structural survey, budget database from Ministry ofFinances and other data sources. It is important that questionnaires of annualaccounting statements are gradually improved following national accounts’35/236
