Berücksichtigt ihr bei der Analyse auch, dass Leute, die TikTok nutzen, sich grundsätzlich in ihren Parteipräferenzen von denen, die kein TikTok nutzen, unterscheiden könnten?

This is really cool (the analysis, not the state of the market). Would it be easy to split these by US / non-US or US / Europe?

This is not surprising. We already know direct carbon compensation doesn't work. And carbon credit trading schemes are just a more elaborate version of the same thing.

Don't make me tap the sign: carbon compensation is a scam.

Are M&As spurring or stifling innovation? Evidence from antidiabetic drug development

Jan Malek, Jo Seldeslachts, Reinhilde Veugelers

July 11, 2025

Abstract
This paper provides empirical evidence on which M&A deals spur innovation, and which stifle it. To do so, we consider not only the product market position of the acquiring firm, but also the position of both target and acquirer in the technology space. Focusing on the antidiabetic drugs market, our dataset tracks the lifecycle and patenting of all individual antidiabetic projects in development between 1997 and 2017. We show that most terminations of acquired projects occur while the projects are still far from product market entry. Nevertheless, a number of these early-stage acquisitions have a positive impact on innovation. These cases arise when incumbents acquire projects close to their own projects in product markets, but only if these projects are also close in technology markets. Those deals are associated with increased subsequent patenting, which is consistent with the exploitation of technological synergies. Our results point to the crucial role of combining both product market and technology market positions in assessing the innovation effects of pharmaceutical M&As.

Very nice cross-country-industry data collection! There can be more nuanced results regarding effects on innovation when carefully combining actual product market and technology data: www.diw.de/documents/pu...

Imo, wäre es besser, wenn Klimaaktivisten und Parteien für das Handelssystem und seine Ausweitung kämpfen würden, statt für Einzelaktionen wie in HH.

What I heard a few days ago: a US faculty member said they would not quote Hannah Arendt in class any more, as a precaution.

Don’t be judgmental about him/her - but it‘s just so terrible.

Pope Leo quotes Hannah Arendt:

“The ideal subject of totalitarian rule is not the convinced Nazi or the convinced Communist, but people for whom the distinction between fact and fiction and the distinction between true and false no longer exist."

Pope Leo calls for news agencies to stand as bulwark against "post-truths," lies and manipulation
Pope Leo XIV has encouraged international news agencies to stand firm as a bulwark against the "ancient art of lying" and manipulation.

This is an exact encapsulation of why I moved to Bluesky.

No amount of handwringing in the Atlantic about how I owe some eternal Promethean suffering to the discourse is going to make me stay on a site I hate, that stopped doing anything for me professionally years ago.
Well – no. Bluesky may or may not be, as one centre-right friend who felt unwelcome put it, “self-righteous island”. But the idea that’s why we went is nonsense. That I’ve largely stopped posting on a site that’s done more to shape my career and social circle than the rest of the internet combined is less about avoiding rival opinions (I love arguing with people who are wrong!) than with the fact the site simply became unusable. It stopped generating the things (good jokes, interesting debate, clicks) I wanted; it became extremely good at generating the things (racists, pornbots, racist pornbots) I did not.
