Richard Thaler et les fausses mouches imprimées Richard Thaler … part de l’idée que si les individus sont incapables pour tout un tas de «biais cognitifs» et culturels de prendre les meilleures décisions, il faut les y aider en les accompagnant dans leurs choix de «tous les jours». D’où son idée d’imposer aux individus des décisions tout en leur faisant croire qu’ils conservent leur pleine liberté de choix. Son application la plus connue citée dans...

Swedish housing bubble soon to burst High and rising household indebtedness poses the greatest risk to the Swedish economy. Household indebtedness has been increasing in Sweden since the mid- 1990s. Home ownership financed by high levels of mortgage debt with variable interest rates makes households vulnerable to falling house prices and increasing interest rates … In the present Economic Commentary, we extend the earlier analysis by using updated data...

Emma Frans och konsten att skilja vetenskap från trams Emma Frans’ med rätta prisbelönta bok Larmrapporten är en rolig, kunnig och ack så nödvändig uppgörelse med allehanda pseudo-vetenskapligt trams som sköljer över oss i media nuförtiden. Inte minst i sociala media sprids en massa ‘alternativa fakta’ och nonsens. Även om jag varmt rekommederat studenter, vänner och bekanta att läsa boken, kan jag dock inte låta bli att här — bland mestadels akademiskt...

Randomization — a philosophical device gone astray When giving courses in the philosophy of science yours truly has often had David Papineau’s book Philosophical Devices (OUP 2012) on the reading list. Overall it is a good introduction to many of the instruments used when performing methodological and science theoretical analyses of economic and other social sciences issues. Unfortunately, the book has also fallen prey to the randomization hype that...

Fammi abbracciare una donna (personal) [embedded content]As always, for you, Jeanette Meyer. 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 So that I could remove mountains, If I have not love … I am nothing.

Randomized experiments — a dangerous idolatry Nowadays many mainstream economists maintain that ‘imaginative empirical methods’ — especially randomized experiments (RCTs) — can help us to answer questions concerning the external validity of economic models. In their view, they are, more or less, tests of ‘an underlying economic model’ and enable economists to make the right selection from the ever-expanding ‘collection of potentially applicable models.’...

DSGE models are missing the point In a recent attempt to defend DSGE modelling, Lawrence Christiano, Martin Eichenbaum and Mathias Trabandt have to admit that DSGE models have failed to predict financial crises. The reason they put forward for this is that the models did not “integrate the shadow banking system into their analysis.” That certainly is true — but the DSGE problems go much deeper than that: A typical modern approach to writing a paper in DSGE...
