New book exposes Russia’s ecocide as a war against Ukraine’s land – and memory When Russia destroyed Ukraine’s Kakhovka Hydroelectric Dam in June 2023, unleashing catastrophic floods across the country’s south, it seemed like such a blatant act of environmental and humanitarian ...

In her monumental work, Darya Tsymbalyuk insists the world must reckon with the full cost of the destruction in Ukraine — not just in hectares lost or tons of grain burned, but in the severed roots that once tied generations to the land they called home.

This is exactly what I meant 🙂

True! Although, as much as there's lots of sharing, there's also lots of personal glory! Still, not too bad!

✅ we show that it's great for analysing fiscal policy effects on the economy
✅ it's the methodological paper for my bsvars package

YAY! 👍

Partial identification of structural vector autoregressions with non-centred stochastic volatility We consider structural vector autoregressions that are identified through stochastic volatility under Bayesian estimation. Three contributions emerge …

✅ we analyse the prior for conditional variances of the non-centred Stochastic Volatility
✅ we argue it's perfect for Structural VARs bc:
1️⃣ it normalises the system
2️⃣ allows reliable verification of partial identification
3️⃣ leads to more precise estimates

👽 There it is! 👾 Our new and shiny paper for the Journal of Econometrics! 🤖 doi.org/10.1016/j.je... 🚀

In this paper:
✅ we provide general conditions for partial identification of Structural VARs through heteroskedasticity

That’s it pretty much! It’s openMP in C++ finally working for me 🤩

🚀✨ The feeling when you have been coding your package in such a way that adding that one line of code speeds up the computations at least 5x!!!
#rstats #openmp #cpp

Ah fun! I’m using ‘beepr::beep(6)’ for the same purpose on a local machine👹🤩

Perfect! This is just what I was looking for! Thanks 💙💛

Also, in Melbourne in general, despite so many vegetarians and vegans out there, the vegetarian restaurant scene has not developed. There are just individual places here and there. Relatively speaking, Warsaw is a vegetarian Mecca! Back to the topic!

That’s a cool paper! I’ll distribute it here and there. Funny enough I have visited many times Berlin unis and Erasmus University in recent years. And indeed the difference is huge relative to Melbourne. There’s always a veg option but the menus are dominated by meat meal - crazy!

Btw it’s so much easier to convince academics to behavioural change. I hear (and practice) a lot statements like: I liked eating meat but stopped bc of what I read. Flying is a different thing bc these folks choose to fly less than they would otherwise but the contractual is not observed.

Similarly, the better equilibrium is where people are healthier, climate change milder, and biodiversity preserved. But we’re all stuck in a bad Nash equilibrium in a prisoners game bc both consumers and producers can’t find a pathway to a better solution at once. An intervention is required…

Good 🧵 I keep reappearing to my economic theory colleagues that getting to the new better equilibrium does not happen by itself. It happens through the groundwork, shifting norms and culture. But changing education system helps a lot here 🤩

Thanks!

Hey, that's my paper! 😍

BTW, I gave two lectures to this paper and the Bayesian treatment of unit-root non-stationarity in my Macroeconometrics subject! And my reproduction of their figures is featured in the subject hex sticker (bc my subjects have hex stickers! 😆) #rstats

Yeah, but in this paper it’s only about simulated data! There’s no real data in the Helicopter Tour paper! Btw it is a masterpiece imho 🤩

🥳 When did that happen! 🎉

Our package bsvarSIGNs has just reached 5K downloads! 🚀

Thank you and stay with us!

It’d be so funny if it wasn’t so serious and literally about human lives.

👾 Only a few hours left 🤖

Join me this afternoon for the online 💙 Workshop for Ukraine 💛 organised by the fantastic ‪@dariia.bsky.social!

Ofc, the several promised cuts will be spread over quite some time, and we should not expect a cut at every single meeting. I believe this was well understood since the beginning of this year. The more surprising was the media drama about the HOLD decision in July.

Not this time! No doubt the RBA is on a slide down with the cash rate. However, my forecasts are firmly centred around the HOLD decision this month. I interpret this as the markets accepting the RBA's pace of interest rate cuts. My forecasts are available at: forecasting-cash-rate.github.io

Nice! Thanks!
