Excited to be in DC to chat Climate-Macro-Modelling for Finance Ministries organised by the Treasury. Lots of potential tools to be developed so that MoFs can fully integrate climate into their decision making processes.

Osziliere seit ein paar Wochen zwischen verschiedenen Ärzt:innen hin und her. Zahlreiche Befunde, Bilder, Laborergebnisse, etc.
Hab mich gewundert, was davon in meiner #ELGA landet. Ergebnis: ein einziger Befund aus den Jahr 2019.
Digitalisierung können wir.

Happy to share my JEEM-publication on "large-N" AND "large-T" panel data in environmental economics studies! 🙂 This structure introduces econometric complexities that can cause erroneous policy conclusions if not accounted for adequately. Check out the paper at: doi.org/10.1016/j.jeem.2024.102941

Ways that researchers can improve the likelihood their outputs will have policy impact include but are not limited to: • Don’t publish in a predatory/low-quality journal • Make work open access or otherwise available • Summarize findings in the title and abstract (please!) • Talk about the work

If emissions have already peaked, or they peak now or in the next few years, it'll be because we fought hard to make it happen!
And guess what we need to do, to make the decline steeper!
Fight hard to make it happen!

This test has already been implemented in the `gets` R-package. Just e.g. run: data(Nile) isat(Nile, sis=FALSE, iis=TRUE, t.pval=0.01) and the Outlier Distortion test is displayed automatically - alongside the Jiao-Pretis Outlier Proportion Test.

We show how this affects commonly used estimates of climate impacts - and also introduce a first estimate for climate adaptation based on income.
These results are similar to our Working Paper here: t.co/79mKII7lkz and show that income will play a huge role in damages.

So in this paper, we introduce the Jiao-Pretis-Schwarz Outlier Distortion Test. This test is is based on the difference between OLS and robust estimates obtained using a class of Huber-skip M-type estimators (such as Impulse Indicator Saturation or Robustified Least Squares).

Most research has been comparing robust and non-robust outliers qualitatively to decide with which method to proceed. This was necessary as so far, there has not been a statistical test to check whether outliers significantly distort coefficient estimates - until now :)

While outlier-robust methods are less efficient (they produce wider SE than non-robust methods), non-robust methods (like OLS) are inconsistent, if the outliers actually distort the coefficient estimates. So how can we approach this trade-off?

Essentially, we try to test whether outliers significantly distort regression estimates.
That outliers can matter a lot when running regressions is really nothing new. Lots of colleagues have been using outlier-robust estimators to alleviate outliers overly influencing results.

Xmas coming early: Really excited to publish a paper in the Journal of Econometrics w Felix Pretis & Xiyu Jiao! Here's a short thread about what we do - and how we show the effects of outliers when estimating damages from climate change.

I mean in a globalised world won't this increasingly be the case? But nonetheless, I think the peaks of these curves were too divergent to ignore, don't you think?

This survey from 2009 is really a wild read. Most climate scientists surveyed thought 4-5C by end of century was the most likely, and that 2C was close to impossible to achieve.
Imagine the results if you took this exact survey again today....

The Remaining Carbon Budget for 1.5°C is now smaller because:
1) We have not reduced emissions in three years
2) Updated simple climate models because of updated historical aerosol emissions
3) Some new method choices

Where does the EU stand with its climate policy? The Climate Action Progress Report 2023 and the EEA’s Trends and Projections report are clear: Current policies are insufficient. The implementation of Fit-for-55 is crucial. However, even with these efforts, more is still required. Here are the facts

Charts that give me hope: IEA projections of wind and solar deployment in the Stated Policies Scenario (STEPS) are becoming more like their projection of what’s needed for the Net Zero scenario with every year.

"As clean energy expands & fossil fuel demand declines in the NZE Scenario, there is no need for investment in new coal, oil, & natural gas" says @IEA
Clean energy is growing👇, but that does not mean the coal, oil, & gas decline without strong policy.
