I have to admit I didn't realize my work was cited this widely... I've never worked for a university and climate is not exactly a fashionable field within economics - so this is quite unexpected. landecon.cam.ac.uk/news/members-d…

I think this is important work. Many thanks to Migle Petrauskaite for leading and Xinru Lin for providing modelling support. Plus Jose Luis Diaz Sanchez and Andrew Blackman for providing comments on an earlier draft.

Coal dependence is a big risk on its own. But as disasters become more common the possibility of simultaneous events rises. From this we develop the plausible worst case scenario.

Passionate about building Msia’s climate resilience? But ever wonder what should 🇲🇾 prioritize? My colleagues crunched the numbers & found: 1. RoN95 reform & carbon pricing, by far, give the max benefit: 5 to 1 2. Mangroves & peatlands: 4 to 1 3. Ag & irrigation: 2.5 to 1

@yinshaoloong at a climate event in Putrajaya today made an important point that the “green jobs” narrative is oversold I (broadly) concur. Once a solar panel factory is set up, you need minimal labor to run it. And as noted by Shao Loong, even the construction phase is getting increasingly automated. This can lead green tech to be *less* labor intensive, (EVs assembly, for example) But looking at jobs in specific sectors can also be misleading. One has to look at *net* job creation & destruction in the economy In that context, primary focus of climate policy (imho) ought to be on: 1. D-ecarbonization 2. A-dapting to a changing climate 3. M-anaging the transition (Frankly my dear, I do give a dam..😅) If in meeting these objectives, there is an overall increase in productivity, then net job creation can be still +ive, even if “green jobs” are fleeting & transient And *this* is the correct metric to measure the impact of climate policy on jobs. Hope more politicians would see climate action & green jobs thru this more nuanced lens…

@heiwen @ApurvaSanghi @MuthukumaraMani Thanks! The irrigation point is separate, as an adaptation measure. On agri and trade the full description is "Introduce GHG standards in agricultural exports, support low-carbon certification and align subsidies with climate targets." Hope that clarifies!

@cacrisalves @IvanWerning @DianeCoyle1859 @dandolfa @darioperkins @R2Rsquared @ilzetzki @jbsteinberg @RelearningEcon @haugejostein @CriticalDev @rethinkecon @rethinkeconGRE @davidmcw @AlexSchwartsman @angusarmstrong8 @FranNunesEcon @coreeconteam Great! Nelson/Winter was clearly pivotal in bringing back evolutionary thinking to economics. And very well written too. I still wonder if we are gradually feeling our way back to the original institutional economics. Do you have any views?

Structural economic change as dynamic resource creation – in their OxREP paper, @DimitriZ, @HectorPollitt, Jean-François Mercure, and Frank W. Geels illustrate how innovation, networks and behaviour are adopted in the global economy. doi.org/10.1093/oxrep/…

New Year’s resolution for anyone wanting to understand real-world economics.
Prof. Steve Keen@ProfSteveKeen

Wrapping Up 2025, I wanted to let you know why I've Been Fighting This Battle for 50 Years. I was 20 years old when I realized I was being lied to. It was 1973. I was an undergraduate at the University of Sydney, and the real world was on fire. The oil crisis had hit. Inflation was skyrocketing, and unemployment was rising at the same time - a phenomenon called "stagflation." According to the textbooks I was forced to read, this was mathematically impossible. The economic models insisted you could have inflation or unemployment, but never both. I sat in lecture halls watching professors draw elegant curves on chalkboards that described a world of "equilibrium" and "perfect competition." A world where banks didn't exist, debt didn't matter, and crises were just accidental bumps in the road. I looked at the chalkboard. Then I looked at the newspaper headlines. The map didn't match the territory. Most students just memorized the lies to pass the exam. I couldn't do it. I led a student revolt that year. We demanded to be taught economics that actually engaged with reality - with the messy, chaotic, debt-fueled world we actually lived in. We won the battle, but we lost the war. The university establishment crushed us, and Neoclassical economics took over the world. Fast forward 50 years, and I am seeing the exact same look in your eyes that I had in mine. You look at the "official" inflation numbers, and then you look at your grocery bill, and you know something is wrong. You hear the Fed Chair talk about a "strong economy," but you see your friends getting laid off and your children giving up on ever owning a home. That feeling you have? That isn’t confusion. That’s your bullsh*t detector going off. And you’re right to feel that. Just like I have. I have spent my entire adult life fighting the "experts" because I know where their bad math leads. It leads to 2008. It leads to the housing crisis. It leads to a world where the rich get bailed out and the rest of us get the bill. I fought them in 1973 because I was an angry student. I fight them today because I refuse to let these delusions destroy what is left of our society. ...It cost the rest of the areas of my life to do so. But I know it’s worth it. For the greater good. I didn't build the Rebel Economist Challenge just for academics and government leaders. I built it for the people who are tired of being told to ignore their own eyes. It took me decades to build that map from scratch. You don't have to wait that long. I am challenging you: Can you learn 50+ years of real economics in the next 7 weeks? I have condensed half a century of fighting, predicting economic crises, and winning arguments into a 7-week roadmap. I am handing you the keys to the machine. Handle them with care. If you try to figure this out alone, you’ll get lost in the noise of 24-hour news cycles and contradictory theories. You will stay paralyzed while the window to prepare for the next crisis slams shut. Learning alone using YouTube, textbooks, and University courses will waste years of your life. How do I know? Because I did it the hard way. And unfortunately for me, I can’t get those years back. But I made this system so YOU CAN.

The return of industrial policy has shifted interest from resource allocation back to creation. The paper shows how economics can catch up, using examples from AI and energy transition.

The result was economics focused on allocation of existing resources, not the growth process. Models had little to say about technological change and how policies could influence it.

New paper in the Oxford Review of Economic Policy. Schumpeter once said "Once you think about economic growth, it becomes impossible to think about anything else”. But our current macro models don’t really do this. bit.ly/48YR3Rf

The idea is not new… Veblen was saying it in the 19th century and it formed the basis of the original institutional economics. But the evolutionary approach got lost and was only revived in the 1980s, remaining very much a heterodox approach.
