The title of the talk is:
Framing and signalling effects of taxes on sugary drinks: a Discrete Choice Experiment among households in Great Britain.
Abstract Taxes or levies on sugar-sweetened beverages (SSBs) have been announced or already implemented in at least 30 countries and local jurisdictions, including in the UK since April 2018. This study analysed whether signalling the tax and framing it as a health related measure has a greater effect on the demand for SSBs in comparison to an un-signalled and un-framed price increase of the same magnitude.We conducted a split-design online discrete choice experiment (DCE) of beverage choices among a random sample of 603 respondents in Great Britain who had children and regularly consumed sugary drinks. Two groups completed the DCE where a tax on SSBs was introduced as a health related (and earmarked) measure and signalled in the price, and a third (control) group completed the same DCE but with no signalling or framing of price changes.A 20% increase in the price of SSBs led to a biggest reduction in the probability of choosing SSBs in the group where a tax on SSBs was signalled and framed as a health-related and earmarked policy. We also found that those respondents who supported government plans to introduce such a tax in the UK had overall a greater likelihood of responding to the tax. As we had access to revealed purchase data on soft drinks from the respondent households, we were also able to compare these with stated preferences. DCE was able to capture preferences between beverages relatively well but under-estimated opt-out.
