Education and Social Capital – Corrigendum

In the original publication of Apfeld et al (2021), a coding mistake caused the results plotted in Figure 4, which separately estimates the effect of university attendance on social capital by respondents’ year of high school graduation, to be incorrect. The corrected figure appears below. The corrected results, while somewhat different, do not change the overall inconclusive nature of these findings. As stated in the original article, it would appear that once the data are broken into subsamples there is inadequate power to estimate each subgroup effect precisely enough to learn which are larger and which are smaller. Note that the point estimates are not generally centered inside the confidence intervals because the confidence intervals use a robust bias correction while the point estimates do not, both following the standard options in the function used for these analyses (see original paper for further description).
