Je soupçonne que ce que tu veux mettre en avant, c'est un effet Kuznet, c'est à dire le fait que par euro dépensé, les riches émettent moins que les pauvres. Il y a des arguments en ce sens, cf. par exemple ce graphe :

Hum... Je crois que je passe trop de temps sur our world in data...

D'où l'importance de mécanismes incitatifs / de régulation (quota, interdiction, taxe carbone).

A final methodological point: Roeland spent a lot of time developing an adaptive algorithm for online choice trial generation. The idea is that you always draw choice features from the momentary indifference curve, while updating your estimate of that curve…

The main model-based result is that this spillover can be modeled as an additive bias in the choice function, modulated by mood. So, mood can be interpreted as influencing the *predisposition* to choose the costly-but-rewarding option.

The main model-free result is a spillover from mood to choice so that *highly-rewarding but costly* options are chosen more when moods are positive, while *uncostly but less rewarding* options are preferred when moods are negative.

The purpose here was to study the effect of mood on unrelated choices. We chose economic discounting as a decision-making paradigm, where 102 participants traded off costs (a risk, a delay, or a physical or mental effort) against monetary gains. Note the novel visualization!

By manipulating the difficulty and positive-feedback rate in the quiz, we created episodes of high mood (yellow) and low mood (blue). You can clearly see the divergence of self-rated mood over the course of an episode.

This paper is the latest installment in a series where slow mood fluctuations were induced in a quiz task:
