Will the UK's sugar tax on soft drinks work?
A sugar tax on soft drinks has come into force in the UK. Manufacturers now have to pay a levy on the high-sugar drinks they sell. The tax is aimed at reducing the consumption of such drinks and levels of obesity, particularly among children. A few other countries, including Mexico, France and Norway, have similar levies. So do sugar taxes work? Professor Nava Ashraf, from the London School of Economics, is a leader in the field of behavioural economics.
