“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces. Part of the payoff has been invisible — in the air itself.” Leadership, strategy, real action, common sense. #Paris

Paris said au revoir to cars. Air pollution maps reveal a dramatic change.

Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.

Some professional news: I'll be starting as a co-editor at the Journal of Development Economics. I'll do my best to be constructive, fair, and fast. Looking forward to reading what you are all up to... as I hope you are looking forward to my future referee requests #EconSky

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Does anybody have a good visualization to explain how interactions can be confounded, and why interactions require interaction controls? @urisohn.bsky.social maybe? (Asking because I have an idea, but want to check out what exists already before investing the effort)

On the verge of declaring defeat with chatgpt in my asynchronous online dataviz class. Something changed this semester compared to past ones and SO MANY assignments are essentially 100% LLM output.
