The UK recently introduced a 'soda tax' - a tax on the consumption of drinks with added sugar. Rachel Griffith discusses the effectiveness of such measures in reducing the consumption of sugar among children. This video was recorded at the 2018 RES Conference.

A growing number of jurisdictions have adopted taxes on sugary drinks to help combat excessive sugar consumption. This column simulates the introduction of a volumetric tax on sugary soda in Britain to examine how well targeted such taxes are. The simulated tax leads young people to reduce the amount of sugar they purchase via soda by around 80% more than the average consumer, but is less effective at targeting people with a high-sugar diet.

Although not a nudge, the ‘soda tax’ in the UK can nonetheless be justified in part on behavioural grounds. This column analyses the potential effectiveness of the soda tax in reducing consumption. As a behavioural instrument, the tax does not go far enough, and is in fact regressive.  A comprehensive junk food tax should be introduced instead, accompanied by nudges, ‘healthy’ subsidies, and regulation of ‘super-sizing’ practices.
