Abstract

fetched live from OpenAlex

How is merger-generating efficiency dealt with in antitrust regulation? The Japan Fair Trade Commission (JFTC) presents a consumer welfare standard, which focuses on the change of consumer welfare in evaluating efficiency. Guidelines of U.S. antitrust law and those of EU competition law support this standard as well, and the experience in Canadian competition law reveals the difficulty of applying a total welfare standard. In this paper, we examine the possibility of convergence between market power analysis and efficiency consideration under the consumer welfare standard. Based upon that, we propose a modified consumer welfare standard, under which welfare can be traded off among consumers.

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.
