Challenges in the implementation of SIMSTAT Introduction Nordic meeting 16 September 2014 Jennie Bergman

Introduction Sweden is not part of ESSnet and the pilot study Presenting SIMSTAT to the Advisory Scientific Board of Statistics Sweden in October 2014 Professors from universities and representatives from other statistical institutes Discussion and recommendations on future work Main focus on methodological questions

What will happen if SIMSTAT is implemented? Mandatory exchange of micro-data for dispatches One/two new variables for dispatch partner id and/or country of origin Optional collection of arrivals (coverage rate not regulated in EU legislation) Member states decide themselves how to use the exchanged micro-data Not at all Only for quality checks and asymmetry studies Mixed mode: use the exchanged data to some extent and still collect some arrival data Use the exchanged data and no collection of arrivals

What will happen in Sweden? The burden for the Swedish dispatch PSIs will increase Only collects mandatory variables today Short term: Will not be able to use the exchanged micro-data due to resource constraints Medium term: Use the exchanged data for asymmetry studies and quality checks Long term: Have to reduce the burden -> lower the coverage rate for arrivals so less enterprises have to report and use the exchanged data

Opportunities and challenges Response burden Data quality Time-series Asymmetries Confidentiality and trust of PSIs Changes in publishing Work process Publishing date Data handling and administrative problems Collaboration and interdependence between NSIs Control over the data

Questions for discussion Which are the main challenges and how should we deal with them? Which are the most important questions to discuss with Eurostat? Do you see any problems with adding ‘country of origin’ on dispatch? If using a mixed-mode approach, how will you handle it? Results of the quality evaluation (DK)?
