Increasingly EU law (in particular EU consumer law) is being driven by a school of thought known as 'behavioural economics', which takes into account the behaviours of individuals when they are exercising choice. Regulators recognise that behavioural economics could have a profound impact on many of the most serious challenges facing policy makers today and increasingly see an opportunity for behavioural economics to support more specific issues like complexity, consumer inertia, marketing and the impact of communications to consumers. This session provides an overview of how behavioural economics is quickly becoming a "game changer" for the shape of regulation for time to come.
