Abstract
Abstract We examine benefits of international diversification for the period 1 January 1988 to 30 June 2000. We introduce a new variable (lambda) that measures these benefits more directly than do the pairwise correlations among equity markets, which are used in most other studies. Our study shows that despite international integrations, the benefits of international diversification measured in USD persist. Using lambda, we provide evidence that the increase in co‐movements between equity market returns (measured in local currencies) has been counterbalanced by movements in exchange rates. We confirm our results by subjecting the trend in lambda to several tests.

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 it
