Objective
The harmonisation of European surveys run by national institutes is a task of growing importance for the European statistical system. The European Community Household Panel (ECHP) switched in three countries from input harmonisation with strict comparability of questionnaires and statistical routines to ex-post harmonisation with reduced comparability of questionnaires and statistical routines. This switch of method was caused by the stop of three national sub-samples and their replacement by ongoing household panels run by other institutes.
It is the overall objective of Chintex by means of this unique data situation to clarify if it is necessary to have centralised, standardised survey instruments to achieve harmonisation and comparability or if this objective can also be achieved by ex-post harmonisation, by which independent national sources are satisfactorily converted to common concepts, definitions, survey questions.
Furthermore, the project investigates important hypotheses about the data quality of panel surveys (non-response, reporting errors and panel effects) which are of general interest for survey statisticians.
Work description:
The project starts with an assessment of the attained level of harmonisation in the three national conversion projects with respect to variable conversion and application of unique imputation rules and weighting schemes.
In a second step taxonomy of conversion problems for non-trivial cases shall be established to produce results of general interest. The project will demonstrate exemplarily how statistical tools may be used.
Another branch of harmionisation is the use of common rules for imputation and for the construction of weights. The variability of population estimates according to these two sources is investigated.
Furthermore we will look upon the impact of field related factors that cannot be harmonised ex-post. Their potential impact on non-response, quality of income data and estimation of statistical models will be examined to check weather long running panels have lower non-response and a better quality of income data.
On the other hand panel attrition is regarded to introduce a bias for the estimation of statistical models. CHINTEX will investigate this hypothesis by comparing estimates from the old panels with those from new ones and by using register information in the case of the Finnish ECHP sample. This register information will also be used for a quality assessment of the ECHP imputation rules with respect to income.
In addition, a cross-validation approach is used to exploit the information of the parallel panels. If the evaluation indicates a poor performance of the ECHP imputation rules, alternative suggestions shall be made.
In this respect CHINTEX will concentrate on the longitudinal aspects of imputation. The project will organise three workshops open to academic and official statistics to disseminate and discuss its results.
Milestones:
The project establishes new methodological framework for the conversion of data that can be used for the ECHP but can be generalised for other surveys. It presents empirical evidence on the effect of switching from input to ex-post harmonisation and analyses the effect of the ex-post approach in producing comparable information. Insight on the impact of panel duration on the quality of the data is given and important hypothesis about possible panel effects are tested.
The project presents an evaluation of the ECHP imputation rules on income and suggests alternatives whenever necessary.
