With Australia being first-mover to legislate for plain packaging of tobacco products, and given the closeness of our countries, the noise level is rising on what New Zealand’s policy should be. Generally that debate is providing a great deal of heat and very little light.

Commentators with backgrounds in public health, sociology, intellectual property law/international law, policy analysis, and politics, not to mention the opposing strident cat-calls of anti-smoking lobbyists and tobacco corporate interests, have all been widely reported.

But one voice that has been largely missing from this debate is that of the dark science, economics. Yet economics is the expertise best suited to predict this outcome, being the science that explains dynamic responses in dynamic systems whereas all the other disciplines that have fuelled the debate are directed at steady-state and single point analysis of the problem.

So what do economists think will be the consequence of plain packaging on smoking incidence?

There is surprising consistency (for economists) that if applied as an independent lever, introducing plain packaging will not reduce smoking but will cause consumption to increase!

One evidently independent economic study hails from the Montreal Economic Institute1 which reviews the appropriate literature and concludes “…no causal relation has been established between plain packaging of cigarettes and tobacco consumption. In other words, there is no scientific basis for the promotion of plain packaging.” Then, taking graphic health warnings as the best real world indicator of labelling effects on consumption, the authors observe “one year after appearing on Canadian packs of cigarettes in 2001, aggressive, graphic health warnings had had no statistically significant effect on the proportion of smokers in the population, even in the 15—19 age group.”

They also note that the more graphic health warnings required in Canada had not resulted in statistically lesser smoking incidences than in the USA where substantially tamer and less prominent health warnings are required. So they infer that strictures on packaging and labelling are unproven in providing the benefits they are installed to deliver.

Given that starting point these authors then address the economic consequences and state “In fact, by abolishing the brand premium, we can predict that sales will increase, according to the law of demand.”. At the conclusion of their paper the authors observe “(I)nstead of reducing health risks, this policy would achieve the exact opposite of its stated purpose by leading to an increase in the number of smokers. It would not be the first time that a seemingly well-intentioned policy produces harmful unintended consequences.”

Even economists serving opposite masters (Jorge Padilla of LECG Consulting funded by Philip Morris International2 vs Howard Reid of Landman Economics funded by ASH – Action on Smoking and Health3) agree that debranding will cause the price of cigarettes to drop, and greater cigarette consumption will result unless a further action (say, a countervailing tax) is taken to restore the original price point. Padilla’s economic models and a simulation experiment predict an increase in consumption of cigarettes of between 2.6% and 16.6%.

Reid (of course) claims this is “overstated” but he does agree that a level of increased consumption is an assured economic consequence when plain packaging is used as an independent lever. (Note however that Padilla’s assertion derives from an experimental simulation, whereas the rebuttal of Reid is entirely founded on theory.)

Elsewhere4 Prof. Harry Clarke and David Prentice both from the School of Economics, La Trobe University, have also assessed the economic impact of plain packaging on consumption of cigarettes. The conclusion of their review is “(p)rovided that tax increases offset any induced fall in prices that might result, plain packaging will reduce cigarette consumption.” (emphasis added).

In that context, the statement later attributed to Clarke that “…plain packaging package seems at worse to be a costless experiment that provides valuable information on the effectiveness of plain packaging at almost zero public cost.”5 misrepresents their own findings as, consistent with the view seen for every other economist who has studied the problem, they find that pulling the debranding lever alone will in fact increase rather than reduce, cigarette consumption.

Disclosure: I am a vehement anti-smoking advocate but try to be rational about it!! And lest it is not obvious, I am not an economist.
