Do carbon offsets work? Evidence from the world’s largest offset programme
Carbon offset programmes allow polluters to pay others to reduce emissions on their behalf. In theory, this can achieve the same emissions reductions at a lower cost, but only if the payment actually ...

Thanks to @nberpubs.bsky.social for summarizing our study on payments for ecosystem services (PES). With a simple contract tweak, the cost to conserve additional forest thru PES plummeted. The cost per hectare shown here maps to permanently averting a ton of CO2 for <$5. www.nber.org/digest/20241...

The Environmental Inequality Lab team have been working to build frameworks for real-time analysis of natural disasters and extreme weather events. The goal is to forecast vulnerability, identifying who, rather than just where, will be exposed.

#EconSky #ETP-Tour I will be in San Antonio for the AEAs. @paulgp.com and I are playing tennis at some point on the Friday. If anyone else is looking to play tennis let me know as I'd be keen to play Saturday as well.

If you're a senior male economist and would be interested in discussing the drafting of an open letter re the newly announced IZA leadership change, e-mail me.

Female econs are rightly tired of the burden of such efforts falling on them.

#EconSky On January 1st 2024, I will be ending my association with IZA. My previous association will not be invisible, instead it will appear as strikethrough text on public materials.

#EconSky Two thumbs up from the Department! Thank you to everyone that wrote my letters, I greatly appreciate the support! Let's go!

#Econsky Who is doing modern IO in the Ag Space. Paul Scott and Will Rafey come to mind but I'm not thinking very deeply. Help me broaden my horizons, @marcfbellemare.bsky.social @jeffbloem.bsky.social :)

Getting this started early #econsky, but who wants to play tennis at the AEAs in January?

@jmcolmer.bsky.social and I are in. @florianederer.bsky.social might be in. Anyone else?

#Econsky We're looking to hire someone to help us level up our graphics/figures/presentation of results? Has anyone done this before. We have in mind someone who can work on a project-by-project basis, rather than hiring someone in-house.

Alright, let's try out the new hive mind. I'm at Yale for the next couple of days. Where/What should I eat/drink/see? #Econsky 📉📈
