Efficiency of Family Bargaining Models with Renegotiation: The Role of Transferable Utility across Periods
Bibliographic record
Abstract
In dynamic family bargaining models, it is often assumed, for simplicity, that spouses have transferable utility as well as identical and constant marginal rates of intertemporal substitution. It has been argued that as long as spouses are at an interior solution, renegotiation does not hinder efficiency. We show that identical and constant marginal rates of intertemporal substitution (i.e., transferable utility across periods) are the source of this efficiency result. Even at an interior solution, renegotiation can cause inefficiency if marginal rates of intertemporal substitution are not constant. Our model is the first to both identify this source of inefficiency in a bargaining model in which the threatpoints of later periods are determined endogenously and demonstrate that there is no one-size-fits-all policy regulating divorce that can restore efficiency when couples are allowed to differ in their initial wage rates and/or preferences.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
