Marknadsstyrd skola? Nej tack! Det är allvarligt att likvärdigheten brister i dag, men tyvärr blir det inte bättre utan skevheterna ökar med tiden när vi har ett fritt skolval och en rörlig skolpeng. Den dystra slutsatsen är att Sverige allt mer blir ett samhälle där du måste vara född i rätt familj och med ett starkt socialt kapital i bagaget för att kunna lyckas i livet. Det är en tankemodell som tyvärr kommer att vinna mark. Att inte se problemen med...

Die Pandemie prägt derzeit auf beispiellose Weise die Wirtschaft weltweit. Doch nicht überall ist die Reaktion der Unternehmen dieselbe. In der Krise strukturieren deutsche Konzerne ihre Führungsetagen um, allerdings ganz anders als ihre Wettbewerber in anderen westlichen Industrieländern. Während dort die Vorstände deutlich weiblicher werden, sind in deutschen Börsenunternehmen im Krisenjahr zwei Mechanismen zu beobachten: eine Verkleinerung der Vorstände und der Rückgriff...

As always, for you, Jeanette. Though I speak with the tongues of angels, If I have not love… My words would resound with but a tinkling cymbal. And though I have the gift of prophecy​… And understand all mysteries… and all knowledge… And though I have all faith...

[embedded content] From a theoretical perspective, Simpson’s paradox importantly shows that causality can never be reduced to a question of statistics or probabilities. To understand causality we always have to relate it to a specific causal structure. Statistical correlations are never enough. No structure, no causality. Simpson’s paradox is an interesting paradox in itself, but it can also highlight a deficiency in the traditional econometric approach towards...

Conditional exchangeability and causal inference In observational data, it is unrealistic to assume that the treatment groups are exchangeable. In other words, there is no reason to expect that the groups are the same in all relevant variables other than the treatment. However, if we control for relevant variables by conditioning, then maybe the subgroups will be exchangeable. We will clarify what the “relevant variables” are, but for now, let’s just say...

Le plan de relance français est-il déjà obsolète avant d’avoir servi ? En tout cas, sa forme et son application sont sérieusement remises en cause par le deuxième confinement qui est en train de replonger dans le rouge tous les indicateurs économiques, ragaillardis à la faveur de l’été. Il voyait pourtant loin cet ambitieux dispositif, baptisé « France Relance », le regard volontairement tourné vers 2030. C’est bien justement ce qu’on lui reproche aujourd’hui : avoir la tête...

The atoms are dancing.Thanks to Him the universe is dancing.The souls are dancing, overcome with ecstasy.I’ll whisper in your ear where their dance is taking them.All the atoms in the air and in the desert know well, they seem insane.Every single atom, happy or miserable,Becomes enamoured of the sun, of which nothing can be said.Jalāl ad-Dīn Muhammad Rūmī (1207-1273)
