If you prefer a more abbreviated way to get the gist of the study, here's a short interview on CBS I got to do: www.cbsnews.com/video/plasti...

Despite the good news, it's important to note the decrease in plastic bag litter is relative (compared to places w/o policies). And only for plastic bags (e.g., we don't find ⬇️ for other plastic items). Which means more comprehensive policies are needed to address the entire lifecycle of plastics.

Thanks Florian, that means a lot coming from you!! 😊

Thanks for the comment. I do use weather variation, which ofc has limitations. But responses are consistent in diff. baseline climates (UK/Mexico) suggesting they'll persist as hot days become more common under CC. Importantly adaptation constraints (for LI consumers/platform workers) may intensify.

thanks for reposting, Jesse!!

There's a lot more in the paper (https://pappanna.github.io/jmp/apapp_jmp.pdf), but I'll stop here because no one likes a super long thread (and by that I actually mean: I have many more job applications to finish 🙃).

I then run a survey to explore the mechanisms. Platform workers believe that declining tasks/working ⬇️ hours, especially during peak demand like hot days, deprioritizes them for future work. This constrains the often lauded flexibility of gig work, particularly when environmental risk are high.

On these hot days, food delivery gig workers work up to 2 hours more! This is in contrast to existing literature showing ⬇️ in labor supply in response to extreme heat for other climate-exposed workers in traditional industries (e.g., ag/construction). However, workers' hourly wages do NOT go up.

My JMP shows that gig economy platforms help consumers adapt to climate change, but shift climate-related burdens onto workers. First, I show using millions of transactions in four countries that food delivery demand ⬆️ on hot days relative to moderate days. (Order size, tips, & times don't change.)
