A few days ago, the usual bunch at Otago put out a press release about some surveys they conducted about tobacco labelling. The article is here; I've copied their main results table below.
This is the sum total of the paper, really. They ran the survey, these are the results. Again, I remain pretty amazed at how easy it is to get published in some outlets. Nothing on demographic covariates; nothing on education/smoking interactions on views... hard to see a there there.
What does the survey tell us?
- Both smokers and non-smokers think there should be warning labels on tobacco products, though non-smokers are more likely to agree;
- Non-smokers think attractive packaging encourages smoking initiation; smokers disagree.
- Crampton's editorialising: Presumably smokers are more likely to know what got them started.
- Crampton's editorialising: Branded packs should encourage smokers to stay with their chosen brand - they're an effort to build customer loyalty in what's otherwise pretty easily a homogeneous commodity product.
- Crampton's editorialising: Again, why do we think that smokers would be wrong on this one? They remember what got them started on smoking.
The second survey, according to the press release, tells us that there are identities around brands. That isn't surprising; it's the point of branding.
Nothing in either survey really tells us what's likely to happen if plain packaging is imposed. Here, I put a lot more weight on basic theory than on surveys. And theory tells us that once you pull brands out, cigarettes become more homogeneous. Smokers then become more cost sensitive across brands and are more likely to shift downwards towards cheaper brands. When that happens, smoking rates among smokers may increase; Clarke, linked above, doesn't think the price shifts will be substantial enough to have large price effects - he reckons it can be offset by tax increases in any case. But neither he nor I really know the scale of likely effects. And Janet Hoek doesn't know either.
The Otago Daily Times reports on BAT and Hoek's dispute. Recall that Hoek's evidence above is entirely survey stuff.
She says people like plain packaging. He says there's no evidence that it'll work. She says he's ignoring the evidence that people like plain packaging. What evidence there is in the Hoek paper suggests, at least to me, that the cohort of people who are smokers don't think that plain packaging will do much to reduce uptake or to encourage quitting; I don't put much confidence in survey measures of this sort, but if I had to bet, I'd bet on the estimates from the folks who are smokers rather than the ones from the folks who aren't. And the rest of the international literature on which Hoek would draw suffers from the problem that, because nobody's ever tried plain packaging, we can't really tell what would happen.A University of Otago researcher has hit back at comments by a tobacco industry spokesman who said plain packaging would not reduce tobacco consumption.On Wednesday British American Tobacco (BAT) general manager Steve Rush responded to the findings of Otago University's Aspire2025 research group, which found that two-thirds of respondents supported plain packaging. Mr Rush said the research did not prove plain packaging would reduce tobacco consumption."The research is attitudinal and is based on opinions. It's about how people think they might behave in the future. It's not about how people actually behave," he said.Tobacco packaging did not influence why people started smoking or quitted, he said.Prof Janet Hoek, from university's marketing department, hit back yesterday, saying Mr Rush's remarks about her team's research were "illogical, unsupported" and ignored a "well-established evidence base"."He has trotted out the same tired arguments in a failed attempt to disguise the fact that there is very strong public support for plain packaging, and very little sympathy for the arguments his company is investing hundreds of thousands of dollars trying to promote.
I worry that most of the support for plain packaging comes less from potential effects on smoking rates but rather from this kind of sentiment:
@ericcrampton who cares if it works or not - any handicap put on tobacco companies is good in my books @metiria @dpfdpf @danylmc @keith_ngIt's stuff like this that makes Baby Pareto cry.

Nobody really knows what the effects of plain packaging will be. If we and the Australians cared about finding out whether plain packaging had any effect, we'd be setting up a randomised control trial across the two countries such that some areas would get plain packages and others wouldn't. Instead, both countries seem to be bundling plain packaging with a host of other anti-smoking measures that will make it pretty hard to sort out later on whether any change in smoking rates was due to plain packaging, changes in tax rates, time trends, or something else.
Harry Clarke, who supports plain packaging, suggests that one of the main potential benefits of its adoption in Oz and NZ is figuring out whether the policy does anything:
This conclusion does not mean PP legislation will have strong effects in reducing demands. This depends on the dissuasive impact of PP on consumption. But it is very unlikely that such policies would be counterproductive in the sense of increasing demands. A weak argument endorsing Australia’s adoption of PP policies is that they will have some positive effect in reducing demand without causing any harmful effects. An important gain is determining whether such policies will be very effective or not. Such innovative policies provide a “global public good”. There is often a Prisoners’ Dilemma case against delivering such public goods but, because the policies are likely to be non-disadvantageous, there are no extra costs if Australia is the first country to try out such policies. Indeed Australia has advantages over other developed countries in performing such an experiment. It is remote and physically isolated compared with European, developed Asian or even North American nations. This reduces problems of illegal cigarettes and private importing. Possibly only New Zealand is better as a laboratory. Altruistic provision of global information on the effectiveness of PP should provide benefits in reducing smoking but, at worst, will cost Australia nothing and boost its image as a good global citizen.But it sure will be hard to run that policy evaluation. We'll likely be able to say "the bundle of plain packaging and substantial excise hikes and other stuff led to X", but disentangling effects would require that there's reasonable ex ante price variation across Australian states so we'd have different proportional changes in total prices with the excise increases.
I'd also disagree pretty strongly with the "will cost Australia nothing" conclusion. Even if you just hate tobacco companies and count their utility negatively, every policy of this sort that's adopted increases the chances that it'll be adopted for other products. The UK Health Select Committee just a couple of months ago was talking about considering plain packaging for alcohol, while promising that they'll not consider it for food. I'm still nervous for Count Chocula. The policy buys some fights on trade policy that could well be pointless. And, it's another step down the road that says that even if we provide all the relevant information to consumers, consumers are incompetent to make their own choices and public health experts should get to choose for them. I don't like that road; every step on it is costly if you like consumer sovereignty.
