Happy to share that the recently accepted paper in Journal of Business Ethics with Mariëtte Kuiper and Henri Dekker is now available online: rdcu.be/eD1AL
Conflict of interest disclosures may reduce misselling but also shift advisors' attention to products without disclosure requirements.

Effects of distrust on compliance are more nuanced and careful communication can enhance compliance. For this, it seems important that people can prove the one who distrusts wrong, but more research is needed.

As promised, let's start exploring the latest JPART issue.

Do people follow rules less when they feel distrusted? 🤔 Not always. 🧵

Great to see the paper (with my fantastic colleague Juan Mendoza) in the latest issue of @jpart1991.bsky.social

Takeaway: Distrust doesn’t always lead to backlash; when communicated carefully, it can sometimes enhance compliance.

And a very nice illustration of failing to sustain a cooperative equilibrium. Indeed, cooperation can be realized in an indefinitely repeated game, but if you don't care about the future....

@kclausing.bsky.social My colleague (Kees Camfferman) did a quick check; the numbers seem to be for each country the trade deficits divided by US import. Indeed not tariffs at all ...
jaccowielhouwer.bsky.social
Aren't the figures in the left column that should be 'reciprocated' trade deficits/import? It has nothing do do with tariffs levied by these countries
jaccowielhouwer.bsky.social
Look at the left column: that is not the tariff charged (but trade deficit/import). Apparently it is fine to lie. Following this logic, Australia should get a negative tariff...

Nu in de Eerste Kamer een uitzonderlijke derde termijn met centraal de vraag of het rechtmatig is dat het kabinet het bestuursakkoord van 2022 wil openbreken voor de desastreuze bezuinigingen op universiteiten en wetenschap. Doe.het.niet!

De Eerste Kamer debatteert over de begroting van OCW en dat gaat vooral over de enorme bezuinigingen die de universiteiten en wetenschap treffen. Leden van de Tweede Kamer die tegen deze begroting stemden steunden de actie. 🟥
jaccowielhouwer.bsky.social
Stap 1: stop (grote delen van) deze bezuinigingen. Stap 2: Kijk dan voor een evt fonds om buitenlandse wetenschappers hierheen te halen.
Laten we niet de mensen hier ontslaan om vervolgens mensen die in de VS hetzelfde overkomen hier aan te stellen.

🚨Senatoren, doe het niet! Vandaag debatteert de Eerste Kamer over de desastreuze bezuinigingen op onderwijs en wetenschap. Bezuinigingen die iedereen zullen raken: van studenten tot onderzoekers, medewerkers, het bedrijfsleven en de samenleving als geheel.
Doe het niet! 🟥

If anything, SHORT term orientation is more likely an explanation to deviate from the cooperative equilibrium in which countries lowered / abandoned their tariffs. But in this case even in the short term there seems to be no gain.

Trump Says a Recession Would Be Worth It, but Economists Are Skeptical
President Trump and his advisers say his policies may cause short-term pain but will produce big gains over time. Many economists are skeptical of those arguments.

Proudly I share the first publication of my son Lars Wielhouwer in the Journal of the American Chemical Society. pubs.acs.org/doi/10.1021/...
Electrochemical N-Formylation of Amines: Mechanistic Insights and Sustainable Synthesis of Formamides via a Methylisocyanide Intermediate
Electrochemical methodologies offer a transformative approach to sustainable chemical synthesis by enabling precise, energy-efficient transformations. Here, we report the selective electrochemical N-formylation of methylamine using methanol as both reagent and solvent, facilitated by a simple glassy carbon electrode. Under optimized conditions, we achieve a faradaic efficiency (FE) of 34% for methylformamide synthesis in a neutral NaClO4 electrolyte. Mechanistic insights from in situ Fourier-transform infrared spectroscopy (FTIR) and complementary synthetic experiments reveal two distinct reaction pathways: the direct oxidation of a hemiaminal intermediate and a novel route involving the formation of methylisocyanide, which subsequently hydrates to yield methylformamide. The presence of methylisocyanide was confirmed through mass spectrometry analysis following a successful Ugi multicomponent reaction, demonstrating the ability to safely utilize reactive intermediates within an electrochemical framework. This work underscores the potential of electrosynthesis to unlock metal-free, sustainable pathways to produce value-added nitrogen-containing compounds, paving the way for greener approaches in chemical manufacturing and catalysis.

Dit heeft enorme gevolgen voor studenten, docenten en onderzoekers aan universiteiten, maar betekent op termijn ook enorme schadelijke effecten voor de hele samenleving.

Stop de bezuinigingen op universiteiten en wetenschap! Beste senatoren, Doe het niet!

(3/3) If a candidate announced a tax increase on the poor and middle class to fund a tax cut for the rich, voters would soundly reject that proposal. But tariffs wrap this fiscal switch in a veneer of nationalism.

The state is no longer the managing committee for the bourgeoisie, it’s the managing committee for obscenely wealthy oligarchs who want to avoid taxes & preserve their (short term) wealth above all else. Why capital is supporting the destruction of the US economy from @adambonica.bsky.social

We will see if Tuesday is yet another "boy who cried tariff" moment.

But, still, a good time to re-up this. (Full details in the linked reports within.)
