Alberto Alemanno, “Nudging Healthier Lifestyles: Informing the Non-communicable Diseases Agenda with Behavioural Insights.” Chapter 14 in A. Alemanno and A. Garde, eds., Regulating Lifestyle Risks: The EU, Alcohol, Tobacco and Unhealthy Diets, Cambridge University Press, 2015.
• The European section of the World Health Organization has begun an initiative to combat “lifestyle” non-communicable diseases: those associated with tobacco, alcohol, and goods high in salt, sugar, and fat.
• Regulations that commonly are applied to lifestyle goods include mandatory information disclosure; marketing limitations; taxes and other devices to reduce availability.
• Behavioral economics-style nudges fit well with lifestyle issues. They tend to be low cost and preserve individual choice. Lifestyle nudges might include disclosure rules; default settings; and, simplification. For instance, the extremely graphic photos required on cigarette packs, and nutrition fact panels, are nudges of a sort.
• The European Union (oddly) is requiring that cigarette packs not disclose tar, nicotine, and carbon monoxide content. The rationale is that such information might lead smokers to think that some cigarettes are less harmful than others. (There is some evidence that consumers smoke low tar and nicotine cigarettes more intensely, undoing any relative health benefits.)
• Thaler and Sunstein’s “publicity principle” (borrowed from John Rawls, building on Kant) is that governmental nudges must be supportable if everyone is informed about them. If people will be upset if they were misled, even if the misleading resulted in better choices for them, then the misleading is wrong.
• Much of the evidence for nudges comes from the laboratory, and might not work in the real world. Or, a nudge might work at first, but then become less effective over time. Notice that marketing experts think that nudges work, however.
