You are what your parents expect: Height and local reference points
Fan Wang, Esteban Puentes, Jere R. Behrman, Fl\'avio Cunha

TL;DR
This paper models how parental reference points influence child height and uses experimental data to quantify the impact of nutritional interventions on growth, highlighting the importance of reference-dependent preferences in health outcomes.
Contribution
It introduces a model of nutritional choices with reference-dependent preferences and empirically estimates the influence of reference points on child height using experimental data.
Findings
Reference points explain 65% of height differences in the study.
The model decomposes intervention effects into price and reference effects.
Experimental variation in reference height significantly impacts child growth.
Abstract
Recent estimates are that about 150 million children under five years of age are stunted, with substantial negative consequences for their schooling, cognitive skills, health, and economic productivity. Therefore, understanding what determines such growth retardation is significant for designing public policies that aim to address this issue. We build a model for nutritional choices and health with reference-dependent preferences. Parents care about the health of their children relative to some reference population. In our empirical model, we use height as the health outcome that parents target. Reference height is an equilibrium object determined by earlier cohorts' parents' nutritional choices in the same village. We explore the exogenous variation in reference height produced by a protein-supplementation experiment in Guatemala to estimate our model's parameters. We use our model to…
