The Social Cost of Carbon by @paulkelleher.net. Beach reading this Easter. I thoroughly recommend. Crystallises some thoughts I’ve been having recently on the social discount rate, but helpful in so many other ways on the social cost of carbon. Congrats @paulkelleher.net

This is great news. Finland to restore marshlands, which will (1) act as an natural barrier to deter a Russian invasion, (2) be a carbon sink to slow down climate change, (3) protect biodiversity. Superb!

Some light Sunday reading to fill that post-Olympic void: "Beliefs, evidence, and action towards the green energy transition" with Mark Freeman, @bengroom.bsky.social & @frikknesje.bsky.social Updated working paper: gwagner.com/beliefs TL;DR: both evidence & prior beliefs matter, a lot.

RIP Sly Dunbar. Loved this collaboration: open.spotify.com/track/4QHfFz...

Hooray!

🧰 Resources for PhD students and young researchers The past few days, I have been collecting useful resources that might help younger researchers: - academic writing advice - data-management warnings - econometric tools and methods - and a few other things sites.google.com/view/philipp...

Yes, EU CBAM pushing Indian steel producers toward greener production processes. I only wish people would stop referring to #CBAM as a tariff. Tariffs treat foreign and domestic producers differently, while a CBAM levels the playing field. More like a VAT. www.canarymedia.com/articles/gre...

UK HM Treasury discount rate review. See link below. We’d like responses before 27th Feb. See below. @rff.org @granthamlse.bsky.social @leepinstitute.bsky.social @cep-lse.bsky.social

Lionesses. Utterly brilliant. Spain were Amazing. Great final. Rather emotional in this European household.

One last view over Bergen following a nice #EAERE2025 conference. Always happy to meet friends and colleagues I seldom have the occasion to cross paths with. Including @profejzrobinson.bsky.social @bengroom.bsky.social @elchinosauro.bsky.social And many others @eaere.bsky.social

I was recently asked “What is the most important piece of advice you would give to a new assistant professor?” My new blog post covers the answer. #EconSky

Our latest working paper provides new insights into the economic value of the Congo Basin forests and how the supply of this value is distributed across categories of rightsholders, thereby linking values to the different groups who make management decisions about the forest. www.lse.ac.uk/granth...

I ll present on Tuesday at 2 pm in the session “Forests, land use, and economic development”

Listening to PM on BBC R4 today you would think that the Treasury Green Book is the source of all problems concerning levelling up, regional disparities of government investment and inequality writ large. The Green Book handles value for money. Not the lack of strategy by successive governments.

@moritzdrupp.bsky.social, my supervisor Martin Hänsel and co-authors incl. @bengroom.bsky.social @climatefran.bsky.social @frikknesje.bsky.social @ctraeger.bsky.social were recognized with the Frontiers Planet Prize for planetary health with a paper on the increasing value of nature

There are ways the grid operator can kind of manage this today, but it would happen much more directly if the prices in different parts of the country better reflected the supply/demand balance from hour-to-hour in each region. That’s the idea anyway.

Thank you EDF for requesting this FOIA together the latest EPA GHG Inventory out. We may need to do the same for facility-level GHG emissions from EPA's GHG Reporting Program.

What self-respecting tree surgeon goes ahead with this unquestioningly? Perhaps linking ati.woodlandtrust.org.uk (ancient tree inventory) with upcoming jobs via the @arbassociation.bsky.social would be a good way of quickly raising red flags? Is this a new idea? www.bbc.co.uk/news/article...

This editorial is worth a close read, and a course of action. Fight like our democracy depends on it, because it does. www.nytimes.com/2025/05/01/o... [gift link]

"It is to build a coalition of Americans who disagree about many other subjects...yet who believe that these subjects must be decided through democratic debate and constitutional processes rather than the dictates of a single man." Read, discuss, share. Don't ignore.

On climate policy, all eyes are on California's reauthorization of its world-leading cap-and-trade program. Today, I had the privilege of testifying about the program and its revenue spending priorities before the CA assembly climate budget subcommittee. Start at 1:01:30. #climatesky #energysky

Amazing work @bengroom.bsky.social. Did we mention Ben works on the RENEW project? Just saying.

Funny not funny.

This happened. More to follow on the journey that culminated in the paper and how @moritzdrupp.bsky.social and Martin Hansel guided it through. @leepinstitute.bsky.social @universityofexeter.bsky.social www.lse.ac.uk/granthaminst...

This looks like a great opportunity : www.bangor.ac.uk/sns/commonwe...

A classic paper by Ben Bernanke (from 1980!) seem especially salient today. Perhaps more than ever before. It was eventually published in QJE in 1983. www.nber.org/papers/w0502

Articles like these are total BS. Russia has been declaring "ceasefires" like these for years (including pre-full invasion), then not respecting them itself. These "ceasefires" are not a sign of anything. www.bbc.com/news/article...

Just under two weeks left for applications to this postdoc position. Come join us at LSE! #econsky

Note that this is decidedly different from saying Trump can halt the low-carbon transition. He can't: gwagner.com/policy-pendulum But he can surely delay things, and hurt US competitiveness in the process. And the erratic nature of it all, of course, only hurts.

"Many of the world’s largest shipping nations decided on Friday to impose a minimum tax of $100 for every ton of carbon dioxide emitted by ships...effectively the first global tax on greenhouse gas emissions." apnews.com/article/ship...

Really good analysis. The basics are important.

Aggregate US prices rise by 5%. Sectors with >8% US price increase are metals, clothing, electronics, food, chemicals, and other industrial products. /n

Just a reminder that there is no existing substitute for NIH in terms of biomedical research funding--anywhere in the world. These losses will be felt worldwide. And given spending as of the end of March, we're looking at an effective 60% cut to NIH funding.

Madness. These exports help fund our own students and funnel £ into the university towns and cities outside London. We should be looking to expand capacity to take in foreign students who would previously have chosen the US.

One challenge for trade policy, is that the benefits to consumers (like lower prices) feel vague & abstract—it's hard to see what we'd lose without free trade. Job threats feel immediate, driving support for protectionism. More recent on views on trade👇

(1) Rapid GE trade modeling returns for April 2nd tariffs. We model: April 2nd tariffs + 25% on CAN/MEX imports + 20% on PRC imports + 25% on iron/steel/alum/cars. Fig. shows total tariff by country. Avg. is 20.4%, about 10X pre-Trump rates. What are US and foreign country impacts?
