+            <p><i>May 2024</i></p>
+            <p>This notebook looks at nighttime brightness values for 700+ mini-grid locations across 20 countries in Africa and compares them with control locations using a modern Difference-in-Differences (DinD) method from Callaway & Sant'Anna (2021). The analysis finds that mini-grids do not have a statistically significant increase in nighttime brightness after their installation, indicating that they may not be detectable from space.</p>
