Rechtfertigt Klimapolitik eine Erhöhung der Verschuldung? Plädoyer für eine grün-goldene Regel Zusammenfassung In diesem Beitrag präsentieren Ottmar Edenhofer, Ulrich Eydam, Maik Heinemann, Matthias Kalkuhl und Nikolaj Moretti eine Komponente einer modifizierten Investitionsregel für die Klimap...

der Politik. Die Mittel aus der Verschuldung können flexibel eingesetzt werden. Die grün-goldene Regel löst damit fundamentale Probleme früherer Investitionsregeln wie Anreize zu Fehlinvestitionen und strategische Manipulation des Investitionsumfangs.“ www.degruyterbrill.com/document/doi...

“Die grün-goldene Regel knüpft die erlaubte Verschuldung an nationale Emissionsminderungen oder an die Höhe des CO2-Preises. Dadurch wird die Höhe der Neuverschuldung von den vermiedenen Klimaschäden abhängig gemacht. Dies ermöglicht Wohlfahrtsverbesserungen trotz einer Kurzfristorientierung

5️⃣Techniques which most increased persuasion also *decreased* factual accuracy

→ Prompting model to flood conversation with information (⬇️accuracy)

→ Persuasion post-training that worked best (⬇️accuracy)

→ Newer version of GPT-4o which was most persuasive (⬇️accuracy)

4️⃣Information density drives persuasion gains

Models were most persuasive when flooding conversations with fact-checkable claims (+0.3pp per claim).

Strikingly, the persuasiveness of prompting/post-training techniques was strongly correlated with their impact on info density!

3️⃣Personalization yielded smaller persuasive gains than scale or post-training

Despite fears of AI "microtargeting," personalization effects were small (+0.4pp on avg.). 

Held for simple and sophisticated personalization; prompt-based, fine-tuning, and reward modeling (all <1pp).

VERY excited about this massive AI persuasion experiment - big effects on UK policy positions, driven mostly by post-training (rather than hyperpersonalization or model scale); and the more info the model provides, the more persuasive it is
