Il y a un an, l’OCDE publiait une étude analysant 34 épisodes de réduction durable de la dette publique dans 25 pays de l’OCDE depuis la fin des années 1970. L’étude montre que les efforts discrétionnaires de consolidation budgétaire ont surtout porté sur les… dépenses publiques. Les pays qui se sont appuyés principalement sur les hausses d’impôts ont, à l’inverse, plus souvent échoué à réduire durablement leur ratio d’endettement : oecd.org/content/dam/oecd/en…

Show me economists who have the ability to "dictate", but if this is the call for ignoring expertise then it is a step toward Idiocracy
Economic populism also means dethroning economics. It’s not the job of economists to dictate how our economies should be run but to find solutions to implement democratically determined goals.

Als experts que diuen que hauríem de deixar d'utilitzar el PIB com a mesura del progrés perquè no té en compte la salut, la fam al món, l'esperança de vida, la mortalitat infantil, l'educació, l'accés a l'aigua potable, l'electricitat o mil altres factors, potser caldria recordar-los que, quan analitzem aquests indicadors, descobrim que estan fortament correlacionats amb el PIB per capita. Una imatge que tots els defensors del «decreixement» haurien de portar tatuada al front.

What is life like at different levels of GDP per capita? In this new chart I visualised it for 12 different dimensions.

Mögnuð þróun. AI er ekki síst leikbreytir fyrir fámenna deild eins og okkar í ÍSB :)
Jason Furman has launched Econvitals, a new macroeconomics system. It uses about 500,000 lines of code that he vibe coded using AI models to create a data layer that pulls about 110 sources, including a Fedspeak tracker and a fiscal simulator. (1/4)

Bugün sunum yaparken şu yorum geldi: “hocam faizleri indirsek enflasyon düşer”. Yanıtlarken karşılıklı etkileşimde fark ettim ki bütün yaşananlardan sonra hala bu soruyu sorabilen birini ikna etmeye çalışmak nafile. Bu tip durumlarda anlatmak için iyi bir fıkra bulmak lazım.

Gagnleg yfirferð yfir stöðu mála í opinbera búskapnum í Frans.
This DW clip is actually a pretty good summary of the french socioeconomic situation, i am impressed. Much better than some other content put out by german public broadcasting. If it always was like this we would have way less problems with slopulism.

True in Spain too. Every landlord in Madrid and Barcelona screens the renters now. This is an obvious consequence of rent control. The most vulnerable, ostensible protected by the legislation, are in fact excluded from the rental market: if you cannot be evicted for non payment, then you are too risky a renter.
A friend of mine had to do a 15 minute interview about his job, income, previous rental history, etc, in order to *view* a flat. Luckily for him, he has a well-paid job, has lived in England all his life, and an impeccable rental history. I feel bad for people who don't.

C’est en fait le paradoxe de Tocqueville qui nous éclate à la figure. Dans l’un des pays qui redistribue le plus au monde, le pays qui égalise le plus les conditions objectives d’existence, qui donnent le plus de chance à tous, qui donne culture, éducation et enseignement supérieur gratuitement à tous, qui respecte le plus les droits de l’homme, dans ce pays de cocagne donc, une part significative de la population est persuadée qu’elle vit dans un enfer d’injustices et de violences systémiques. Comme l’avait très bien montré Tocqueville, plus il y a d’égalité, plus les inégalités qui restent deviennent insupportables. Notamment parce que la société méritocratique, par rapport à l’ancien régime fondé sur la naissance, a cela de terrible qu’elle rend les gens responsables de leurs conditions.

Eins og það er lúðalegt almennt að gera sér rellu yfir titlatogi: Í n-ta skiptið, Stefán Ólafsson er ekki hagfræðingur heldur félagsfræðingur. Einhverra hluta vegna sér Stefán samt aldrei ástæðu til að leiðrétta þennan misskilning :) dv.is/frettir/2026/10/19/ste…

Ein þreyttasta klisja hörðustu gagnrýnenda Seðlabankans er að það séu engin orsakatengsl frá launaþróun yfir í verðbólgu. Það var því gagnlegt að fá á fundi SBÍ í morgun sýnishorn úr nýrri rannsókn á þessu sambandi sem vonandi hjálpar við að kveða þessa fullyrðingu í kútinn.

What’s the evidence on rent control? I charted the findings from 112 studies: Great for rent-controlled tenants ✅ But: Pushes up rents for other people ❌ Pushes down new housing construction ❌ Pushes down building quality ❌

Ein skýring á styrk krónunnar undanfarið: Landinn er farinn að minnka ferðagleðina á erlenda grundu á sama tíma og hver ferðamaður virðist hafa eytt nokkuð meiru hér í ágúst en í sama mánuði 2025: islandsbanki.is/is/frett/kor…

Mæli með þessari grein Noah Smith um AI og vinnumarkaðinn. Engin merki virðast enn um hreina fækkun starfa vegna tækninnar og ýmis gild rök eru fyrir því að það sé ekki endilega að fara að gerast á næstunni, eða jafnvel yfir höfuð. open.substack.com/pub/noahpi…

but they were, all of them, deceived, for another watch was made…
Sam Altman @sama just ordered 7 ultra-rare custom Swiss watches from Vanguart, fully branded with the OpenAI logo on the dial. One for him, six for his inner circle. Inscribed on the back of each watch is ‘if AGI.aligned: deploy()’ which was written in the programming language Python.VANGUART This is starting to be a trend in the tech world and I’m all for it — If your company wants customer branded Rolex or other watches shoot me a dm we specialize in bulk corporate orders with custom engraving and dial branding
