Three-generation Mobility in the United States, 1850-1940: The Role of Maternal and Paternal Grandparents
Bibliographic record
Abstract
This paper estimates intergenerational elasticities across three generations in the United States in the late 19th and early 20th centuries. We extend the methodology in Olivetti and Paserman (2015) to explore the role of maternal and paternal grandfathers for the transmission of economic status to grandsons and granddaughters. We document three main findings. First, grandfathers matter for income transmission, above and beyond their effect on fathers' income. Second, the socio-economic status of grandsons is influenced more strongly by paternal grandfathers than by maternal grandfathers. Third, maternal grandfathers are more important for granddaughters than for grandsons, while the opposite is true for paternal grandfathers. We present a model of multitrait matching and inheritance that can rationalize these findings.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
