Le tournant expérimental en économie

Mohsen Javdani and Ha-Joon Changonline examine the effect of ideological bias among economists through a randomised controlled experiment involving 2,425 economists in 19 countries. The analysis provides clear evidence for the existence of ideological bias as well as of authority bias among economists.

Based on a critique on econometric and DSGE models (in particular in the context of the financial crisis), Doyne Farmer presents his current research programme that aims at building an agent-based model of the financial and economic crisis. It models heterogeneous agents and from there simulates the economy, firstly for the housing market. The interview gives a short insight in the research programme.

Pourquoi les économistes doivent abandonner le raisonnement en termes d'équilibre pour apporter des réponses à la crise sanitaire et à la stagnation ? Réponse dans ce décryptage d'Olivier Passet pour Xerfi Canal.

If there’s one method economists have neglected the most, it’s qualitative research. Whereas economists favour mathematical models and statistics, qualitative research seeks to understand the world through intensive investigation of particular circumstances, which usually entails interviewing people directly about their experiences. While this may sound simple to quantitative types the style, purpose, context, and interpretation of an interview can vary widely. Because of this variety, I have written a longer post than usual on this topic rather than doing it a disservice. Having said that, examples of qualitative research in economics are sadly scant enough that it doesn’t warrant multiple posts. In this post I will introduce qualitative research in general with nods to several applications including the study of firm behaviour, race, Austrian economics, and health economics. More than usual I will utilise block quotes, which I feel is in the spirit of the topic.
