The objective of this paper is to capture the association between nutritional status at young ages and subsequent health. To do this, we estimate a dynamic linear panel data model using data from the three waves of the Young Lives Study. We find that the catch-up coefficient in the linear dynamic panel data model varies between 0 to 0.32, where, Ethiopia and India exhibit perfect catch-up and Peru and Vietnam exhibit partial catch-up in height-for-age z scores. To allow for the catch-up coefficient to vary along the entire distribution of child anthropometric outcomes, we also estimate a dynamic quantile regression instrument variable estimator. We find that the null of homogenous catch-up effects along the entire distribution of anthropometrics can be easily rejected.
