Abstract

fetched live from OpenAlex

We examine the correlation between green bond markets of the UK, US, Japan, Canada, Australia, and Europe from 28th November 2008 to 21st May 2021. To measure time-varying correlation, we use extensions of conventional wavelets as wavelet multiple correlation and cross-correlation. Our results suggest sufficient diversification opportunities in the green bonds market because of their recent introduction into the existing asset classes. More specifically, low correlation is reported for UK GBs with Australian Canadian GBs, US GBs with Australian GBs, Japan and Canada, and European GBs with Canadian GBs across all investment periods. We also report non-linear bi-directional causality across the majority of the green bonds market. Our work suggests diversification opportunities by investing in green bonds based on their low time-varying correlation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
