Fig. 2: Dynamic effects of coal mine closure on terrestrial water storage.
From: Coal mine closure substantially increases terrestrial water storage in China
Coefficients on the lags and leads in Eq. (2) are estimated by Ordinary Least Squares (blue circles), Sun and Abraham approach (orange triangles), Borusyak et al. approach (red squares). Their 95% confidence intervals are constructed with mine-level clustered standard errors.
