Enhancement of the Commercial Register to Reduce Response Burden in Economic Structural Statistics Patxi Garrido, Haritz Olaeta, Marta Salvador Helsinki, 5th May 2010
Outline Motivation Data in Commercial Registers Shortcomings of the Data Set Enhancement of the Register Results Conclusions and Future Work
Motivation Increasing response burden. Effects on quality Redundant efforts: official statistics vs. Administrative data Commercial Registers: complete economic information Need to merge sources (partial/complete)
Data in Commercial Registers Only mercantile companies Fiscal site (province) Balance sheet and Profit&Loss account Cooperation Agreement for statistical use “Equity Accounts of Non-Financial Companies” Divisions not included: 12 (NACE)
Shortcomings of the data set Shortcoming 1: Population covered
Shortcomings of the data set Shortcoming 2: localisation of the activity Establishment versus Company Shortcoming 3: Errors Non response Inconsistencies
Enhancement of the register Enhancement 1: division and companies not included Extrapolate mercantil observed values Estimate by Industrial Statistics sub-samples Shortcoming 2: localisation Indirect Ratio Estimation Shortcoming 3: errors in data Validation rules Imputation techniques
Enhancement of the Register Composite Estimator
