The study employs a controlled lab experiment with 166 subjects to test the persistence of the RENOVE rebate programme's effect on fridge purchases. Findings indicate that while rebate programmes significantly increase the adoption of energy-efficient (EE) appliances, the 'memory effect' (continued EE preference after the rebate expires) is more likely among individuals with higher education levels and high environmental concern. Conversely, older participants and those in higher social classes are more likely to buy EE appliances regardless of the rebate, suggesting they are less sensitive to such financial incentives. The research also highlights that decision criteria, such as focusing on energy consumption or lifetime energy costs, significantly influence purchasing behavior.

The study finds that visual appeals (photos) significantly lower the acceptable level of risk by triggering emotional and moral reasoning, though this effect is diminished when numeric data is presented as a range rather than a single value. Additionally, participants who experienced simulated damages increased their investment in protection in subsequent rounds, suggesting a reactive 'gut' response to experience that differs from the reflective reasoning triggered by visual cues.

The research paper employs a lab experiment with 195 subjects to compare public support for taxes and subsidies designed to correct a negative externality. The study finds that subsidies consistently receive higher support than taxes, a gap that is widened when participants have only partial information about how tax revenues are spent or subsidies are funded. While full budgetary information increases support for both instruments, it disproportionately benefits taxes. Interestingly, participants expected taxes to be more effective at reducing the externality than subsidies, despite preferring the latter. The authors conclude that the lack of trust or clarity regarding the use of tax revenues is a primary driver of tax aversion.
