The more the better? Synergies of prosocial interventions and effects on behavioural spillovers.

Incentivising prosocial and pro-environmental behaviours is a sensitive endeavour. While behavioural change is urgently needed to mitigate the consequences of climate change, monetary interventions often have negative side effects. Such interventions are prone to motivation crowding, which can impede lasting positive behavioural change and stimulate negative temporal spillovers to other prosocial behaviours.

EU climate action through an energy poverty lens.

Carbon pricing can steer energy choices towards low-carbon fuels and foster energy conservation efforts. Simultaneously, higher fossil fuel prices may exacerbate energy poverty. A just portfolio of climate policies therefore requires a balanced instrument mix to jointly combat climate change and energy poverty.

Feedback and efficient behavior.

Feedback is an effective tool for promoting efficient behavior: it enhances individuals' awareness of choice consequences in complex settings. Our study aims to isolate the mechanisms underlying the effects of feedback on achieving efficient behavior in a controlled environment. We design a laboratory experiment in which individuals are not aware of the consequences of different alternatives and, thus, cannot easily identify the efficient ones.
