We develop the case of two-stage least squares estimation (2SLS) in the general framework of Athey et al. (Generalized Random Forests, Annals of Statistics, Vol. 47, 2019) and provide a software implementation for R and C++. We use the method to revisit the classic application of instrumental...

We show that the OLS and fixed‐effects (FE) estimators of the popular difference-in-differences model may deviate when there is time varying panel non-response. If such non-response does not affect the common-trend assumption, then OLS and FE are consistent, but OLS is more precise. However,...

Famines are extreme cases of environmental stress, and have been used by a series of studies to explore the long-term consequences of the fetal or childhood environment. Results are inconsistent and do not support negative long-term effects on mortality. The authors test the hypothesis that...

We find that second-generation effects of in utero and early childhood malnutrition on the school participation of the offspring of mothers who experienced the China Great Leap Forward Famine. The direct impact on entrance to senior high school is also negative, but smaller in magnitude than...

This paper uses the Bangladesh famine of 1974 as a natural experiment to estimate the impact of intrauterine malnutrition on sex of the child and infant mortality. In addition, we estimate the impact of malnutrition on post-famine pregnancy outcomes. Using the 1996 Matlab Health and...

This paper provides non-parametric estimates of the total effects of famine in China on marital behavior of famine affected cohorts in rural areas of Sichuan and Anhui. The reduced form estimates incorporate general equilibrium and heterogeneous treatment effects, two important components of...
