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.

Excited to see this paper published! @kimberlyoremus.bsky.social & I find that US plastic bag policies *limit* (but not eliminate) plastic bag litter in the environment, using cool citizen science data from @oceanconservancy.org.

The bad news: Mountains of plastic are piling up in oceans, choking marine life.

The good news: Plastic bag bans work, a new peer-reviewed study confirms.

Just published in Science: www.science.org/doi/10.1126/... by @annapappp.bsky.social & @kimberlyoremus.bsky.social

Excited that our new study was published today in Science.

We found that plastic bag bans and fees reduce plastic bag litter on shorelines by 25-47% compared to places without them: www.science.org/doi/10.1126/... w/ @annapappp.bsky.social

I'm so lucky to have been part of this incredible group and extremely thankful to have had @rmetcalfe.bsky.social's support and encouragement throughout the craziness that is the job market. Very excited for the next steps!

I can confirm this is an awesome gig during grad school - I loved being the AERE social media manager. It's a nice way to meet AERE leadership, read (abstracts) of JAERE papers, attend the annual conference, etc.

Current students - feel free to reach out w/ questions if interested!

For those considering #veganuary, a little plug for a piece I wrote about veganism, one of the best things in my life, last Earth Day. (It's a comic - goes down easy!)

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.)

I'm on the job market! My #EconJMP examines climate adaptation inequality in labor markets (see ⬇️).

This is part of my research on the effects of climate change/plastic pollution on workers & society - often with unique data & an interdisciplinary lens.

Thank you @jenniferdoleac.bsky.social for this amazing annual thread and @uaeeconomist.bsky.social for the repost!

I'm excited to be on the market with so many women working on so many cool things! 🙌

I'm excited to be on the job market along with such awesome researchers (and friends)!
