About me

Sanchayan Banerjee is a doctoral candidate in behavioural and environmental economics at the London School of Economics and Political Science. He is an Associate Fellow of the Higher Education Academy (AFHEA) and teaches in the field of applied environmental and developmental economics and quantitative methods at undergraduate and postgraduate levels in the school.

Sanchayan has developed the economic and psychological theory of Nudge Plus in his doctoral research. He has evaluated this theory of nudge plus against nudges, boosts, and thinks in promoting pro-environmental behaviour, with increasing the uptake of low-carbon foods as a case in point. He has been awarded many prestigious scholarships and grants for his current research, namely the LSE Robert and Dilys Rawson doctoral scholarship, the Knowledge and Exchange Impacts award for outreach of Nudge Plus and the RGS-IBG Frederick Soddy postgraduate award.

His work has been published in leading peer-reviewed journals such as the journals of Behavioural Public Policy and Behavioural Public Administration. During his PhD, Sanchayan has reached out to over 450 policymakers globally to help them adapt in how to Nudge Plus. He has presented the framework of Nudge Plus to the steering group of the Mind, Behaviour and Development unit (eMBeD) at the World Bank and is currently developing a policy brief on how policymakers should decide between behavioural interventions with Peter John and Ralph Hertwig (in collaboration with the OECD).
