| Abstract: | Understanding when and why nudges work is crucial for designing interventions that consistently and reliably change behaviour. This paper explores the relationship between decision-making speed and the effectiveness of two nudges – carbon footprint labelling and menu repositioning – aimed at encouraging climate-friendly food choices. Using an incentivized online randomized controlled trial with a quasi-representative sample of British consumers (N = 3, 052) ordering meals through an experimental food-delivery platform, we introduced a time-pressure mechanism to capture both fast and slow decision-making processes. Our findings suggest that menu repositioning is an effective tool for promoting climate-friendly choices when decisions are made quickly, though the effect fades when subjects have time to revise their choices. Carbon labels, in contrast, showed minimal impact overall but reduced emissions among highly educated and climate-conscious individuals when they made fast decisions. The results imply that choice architects should apply both interventions in contexts where consumers make fast decisions, such as digital platforms, canteens, or fast-food restaurants to help mitigate climate externalities. More broadly, our findings suggest that the available decision time in different contexts might at least partly explain differences in effect sizes found in previous studies of these nudges. |

| Abstract: | We partner with a Public Employment Service to examine whether jobseekers can be encouraged to reskill for shortage occupations. In a large-scale field experiment involving 100, 000 recently unemployed individuals, we provide information on shortage occupations and related training opportunities. The intervention increased participation in transversal training courses by 6%, but did not boost enrolment in occupational training for shortage jobs. Jobseekers also shifted their search towards high-demand occupations, yet employment remained unchanged. These findings suggest that while low-cost informational interventions can influence job search and training behaviour, different approaches are likely needed to drive substantial reskilling among jobseekers. |

| Abstract: | The effectiveness of social and economic public policy interventions largely depends on how the agents who will be exposed to them respond to their implementation. Driven by interdisciplinary research that draws heavily on behavioural science, economics research has undergone a behavioural revolution which has considerably deepened the traditional representation of the determinants of behaviour on which its public policy recommendations are based. This article provides an overview of the implications of these extensive changes in economic thought on public policy-making, applied specifically to the case of tax evasion. Beyond "nudges", the most well-known manifestation of behavioural economics, this behavioural approach enables both a better understanding of the anticipated impact of traditional public intervention tools and the emergence of new levers for intervention. |

| Abstract: | Promoting recycling behavior among consumers represents a major challenge in the context of the transition to a circular economy. This study examines the impact of three levers: digital marketing, behavioral triggers and real-time feedback systems, on citizens' commitment to recycling. A quantitative approach was adopted through a structured questionnaire administered online to a sample of 320 adult participants. Data were analyzed using descriptive, correlational and regression statistics. The results show that digital marketing, in particular content disseminated via social networks, exerts a significant influence on recycling behavior. Behavioral triggers such as gamification or reminders have a moderate effect, while real-time feedback systems appear to be the least effective. The study highlights the value of combining different levers to reinforce consumers' lasting involvement in recycling practices. |
