Abstract
We examine the extent to which performance effects of firms' network positions vary with the ages of the ties comprising those positions. Our analysis of Canadian investment banks' underwriting syndicate ties indicates that the performance benefits of closure ties increase with age, whereas benefits of bridging ties decrease with age. We also find that benefits yielded by hybrid network positions, combining elements of both closure and bridging, are greatest when old closure ties are combined with either very young or very old bridging ties. Our findings support the idea that the advantages firms gain (or do not) from their network positions depend on the relational character of the ties comprising them, highlighting the risk of theorizing structural network effects without also considering the relational and temporal dynamics associated with network positions.

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
