Abstract
Tiebout's classic 1956 paper has strong implications regarding stratification across and within jurisdictions, predicting in the simplest instance a hierarchy of internally homogeneous communities ordered by income.Typically, urban areas are less than fully stratified, and the question arises how much departures from standard Tiebout assumptions contribute to observed within-neighborhood mixing.This paper quantifies the separate effects on neighborhood stratification of employment geography (via costly commuting) and preferences for housing attributes.It does so using an equilibrium sorting model, estimated with rich Census micro-data.Simulations based on the model using credible preference estimates show that counterfactual reductions in commuting costs lead to marked increases in racial and education segregation and, to a lesser degree, increases in income segregation, given that households now find it easier to locate in neighborhoods with like households.While turning off preferences for housing characteristics increases racial segregation, especially for blacks, doing so reduces income segregation, indicating that heterogeneity in the housing stock serves to stratify households based on ability-to-pay.Further, we show that differences in housing also help accentuate differences in the consumption of local amenities.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
