Pollution is an Attack on Human Capital
Here’s the latest video from MRU where I cover some interesting papers on the effect of pollution on health, cognition and productivity. The video is pre-Covid but one could also note that pollution makes Covid more dangerous. For principles of economics classes the video is a good introduction to externalities and also to causal inference, most notably the difference in difference method.
Might I also remind any instructor that Modern Principles of Economics has more high-quality resources to teach online than any other textbook.
