Two stage evaluation of bank branch efficiency using data envelopment analysis
Bibliographic record
Abstract
This research presents a new two stage DEA model for evaluating the efficiency of a bank branch network in multiple dimensions. The first stage involves separate DEA analyses using three different branch performance models—productivity, profitability, and intermediation. Then, a new concept of using the results of these initial models in the second stage is done to provide a measure of overall efficiency and to allow the individual ranking of the branches. The top branches, identified by the second stage rankings, can then be used as benchmarks by management for the creation of “templates” for what new branches should be modeled after. This two stage model is then applied to a major Canadian bank's national retail branch network with the results presented to the bank's senior management. The economic effects of market size and geographical region and their effects on branch performance are also examined.

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.
