Abstract
ABSTRACT Conventional economics assumes workers provide the same effort under penalty contracts and economically equivalent bonus contracts. However, prior research finds that although workers prefer bonus contracts, they provide more effort under penalty contracts. Given these findings, the prevalence of bonus contracts in practice is puzzling. If penalty contracts yield more worker effort, why would employers not use them more often? We conduct experimental labor markets to test whether the prior finding of more effort under penalty contracts than bonus contracts (i.e., the contract frame effect) persists when workers can choose their contract and know that their employer intentionally offered the contract they choose. As predicted, these features of labor markets eliminate the difference in effort between penalty and bonus contracts reported in prior studies. This finding suggests employers may use bonus contracts more often than penalty contracts because they can offer the contract most workers prefer without sacrificing worker effort.

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
