Abstract
With this study we are the first to systematically compare today’s two major counterpartsas a source of accounting and financial data for researchers: CompustatNorth America by Standard and Poor’s and Worldscope by Thomson Financial. Thisinvestigation is conducted for U.S. and partly Canadian data over an extensive periodfrom 1985 to 2003. We examine more than 650 data items available in bothdatabases and address the question of whether or not the decision for one or theother source may have an impact on the outcome of research projects. It is probablycommonly assumed that this impact is minor, but it also leaves room to questioncertain results. We show that the use of both databases should lead to comparableresults, but also find that if, e.g. a size bias, is not treated with care the quality ofresults may differ considerable. Furthermore after 1998 the number of firms coveredby Worldscope exceeds the one covered by Compustat by about one fourth.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
