So: Here's how severely-polluting industrial clusters affect predicted crop yields. Downstream = positive distance = right side

You can see the damage, but it’s small (3%) and the conf. interval includes 0

Plus these are local effects that will decay further downstream

To solve problem 3 (what areas are exposed) we develop new methods to carefully define and map upstream/downstream hydrological relationships

Defining these relationships is trickier than you might think. We discuss 4 ways prior methods can go very wrong

Industrial clusters coincide with a huge jump in river pollution of 300-600%. India’s government names and rates these clusters but doesn’t release public estimates of how polluting they are. We do

To solve problem 1 (bad pollution data) we look at India’s giant industrial clusters and just estimate the effect of being downstream of a cluster. The spatial RD is obvious in Delhi here

Out today in JAERE! We measure water pollution released at India's industrial clusters. Does it hurt agriculture? Surprisingly: Not by much

Come for how we published a paper of null results & with no regression tables

Stay for new ways to proxy for crop yields & map hydrological relationships

Mentoring and networking is about more than brief access to top journal editors and other famous economists, sorry to say @aeainformation.bsky.social

(I appreciate all the individual participants! The issue is the overall approach)
