Taxing meat optimally is a first-best policy outcome to internalize environmental harms. However, meat taxes often lack public and governmental support. Recent research indicates that support for meat taxes can be improved by combining behavioral nudges with fiscal measures. In this study, we...

A shift to more sustainable diets is needed to ensure food security and to reduce the pressure on the environment. Yet, many consumers have misconceptions about the environmental impacts of their diets and lack knowledge on how to prepare sustainable meals. This study uses a mixed-methods...

Researchers across academic disciplines have applied Instructional Manipulation Checks (IMCs) to detect inattentive survey participants (Anduiza & Galais, 2017; Motta, Callaghan, & Smith, 2016; Oppenheimer, Meyvis, & Davidenko, 2009; Paas & Morren, 2018; Peer, Brandimarte, Samat, & Acquisti, 2017; Persson &...

This paper makes a novel attempt at understanding the effect of a classic information nudge combined with a reflective commitment device in influencing the dietary choices of individuals. In doing so, it undertakes a field experiment with an unchanged subject pool at LSE Bankside Residential...

Nudges have been increasingly deployed to deliver climate policies in the last decade. Recent evidence shows nudges are hard to scale–up. So can we use nudges more effectively, or should we rely on other tools of behaviour change? We argue that reflective strategies can enhance nudges by...

We outline a modified version of behaviour change called nudge plus, which incorporates an element of reflection as part of the delivery of a nudge. Nudge plus builds on recent work advocating educative nudges and boosts. Its argument turns on seminal work on dual systems that presents a more...

Adopting low-carbon diets is important to meet our climate goals. Prior experimental evidence suggests green nudges help people adopt such diets, more so when they are encouraged to think through them. In this paper, we re-evaluate this role of reflection in a “social norm" nudge to promote...

Short Abstract: We can scale up behaviour change by accounting for nuanced social complexities in which human responses to behavioural public policies are situated. We introduce the “social brain”, encompassing complex human relationships interacted with elements of choice architecture. It...

Previous studies have shown that our past pro-social actions influence our future ones. So, which pro-social deeds inspire us to do more? Can nudges promoting these deeds crowd out this behavioural spillover? We study a social norm nudge promoting vegetarianism in an online experiment (n=2775)....
