Productivity Growth in Services Industries: Is There a Role for Measurement?
Bibliographic record
Abstract
Productivity growth has tended to be slower in service industries than in goods industries. Anita Wölfl of the OECD finds that measurement error may be responsible for slower productivity growth in the service sector. She notes that some service industries in certain OECD countries have experienced negative productivity growth over long periods, despite intensive use of Information and COmmunication Technologies (ICTs), exposure to international competition, and the existence of economies of scale. Wölfl discusses the several possible sources of measurement error that may lead to this unexpected result and quantifies the impact of correcting for measurement errors on aggregate productivity growth.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
