The avoidable costs of alcohol abuse in Australia and the potential benefits of effective policies to reduce the social costs of alcohol
5.2 Bans on alcohol advertising
The appropriateness of bans on alcohol advertising has been the subject of public and political debate for many years, both internationally and within Australia. Indeed, in a recent development in February 2008 the Australian Senate set up an inquiry into aspects of this issue. The fundamental question has been whether alcohol advertising increases total alcohol consumption and/or abuse, or whether it simply affects brand choice, leaving alcohol consumption unchanged. Generally, public health advocates have argued that advertising increases total alcohol consumption and abuse. The industry’s position has consistently been that advertising leaves total consumption unchanged, merely affecting the market shares of the various brands.
In terms of the design of public policy towards alcohol promotion, this is clearly a very important issue. Accordingly, there has been a considerable amount of international research on the impact of advertising and advertising bans on alcohol consumption. This is a research area which is fraught with methodological difficulties and data deficiencies, but over time the studies have tended to become more sophisticated.
Earlier studies, which largely concentrated on studying the relationship between alcohol advertising and consumption in individual jurisdictions, tend to suggest that the relationship is weak. Later studies, which tend to use international data across a range of jurisdictions, indicate that a positive relationship exists between advertising and consumption—that is, alcohol advertising leads to higher alcohol consumption.
Saffer and Dave (2002, p. 1326) analyse in considerable detail the reasons for this apparent conflict. They state:
- Farley and Lehmann (1994) find that cross-national differences in the response to advertising are relatively small. The use of international data is an effective method for measuring the effect of a ban on alcohol advertising. Data from one country are not as useful since changes in alcohol advertising bans within countries are rare and the imposition of a ban may require an extended period for consumption to adjust. There is, however, considerable variation in the use of advertising bans across countries.
- Later studies have suggested significant effects of alcohol advertising on alcoholrelated problems … Countries with partial restrictions had 16 per cent lower alcohol consumption rates and ten per cent lower motor vehicle fatality rates than did countries with no restrictions, and countries with complete bans on television advertisements had 11 per cent lower consumption rates and 23 per cent lower motor vehicle fatalities than did countries with partial restrictions … After accounting for regional price differences and population variables such as income and religion, increases in alcohol advertising were found to be significantly related to increases in total and night-time vehicle fatalities across US states … It was estimated that a total ban on alcohol advertising might reduce motor vehicle fatalities by as much as 5,000 to 10,000 lives per year.
- In conclusion, restricting the volume of commercial communications of alcohol products is likely to reduce harm.
Table 9 below presents the summary by Anderson and Baumberg (2006, Table 7.11) of the strength of the research evidence on alcohol taxation.

Effectiveness | Breadth of research support | Cost efficiency | |
|---|---|---|---|
Reducing the volume of advertising | +/++ | ++ | +++ |
For the definitions of the ratings see Table 6 above.
5.2.1 Potential reductions in social costs resulting from advertising bans
The evidence presented above can be summarised as follows:- If countries with no alcohol advertising restrictions implemented partial bans, they could reduce alcohol consumption by 16 per cent and motor vehicle fatality rates by ten per cent.
- If countries with partial advertising restrictions implemented full bans, they could reducealcohol consumption by a further 11 per cent and motor vehicle fatality rates by a further 23 per cent.
is assumed the ‘true’ values lie.
Table 10. Assumed percentage reductions if countries with no advertising bans implement partial bans
| Reduction in | Best estimate | Minimum | Maximum |
|---|---|---|---|
| Alcohol consumption | 16.0% | 11.0% | 21.0% |
| Motor vehicle fatality rate | 10.0% | 5.0% | 15.0% |
Table 11. Assumed percentage reductions if countries with partial advertising bans implement full bans
| Reduction in | Best estimate | Minimum | Maximum |
|---|---|---|---|
| Alcohol consumption | 11.0% | 6.0% | 16.0% |
| Motor vehicle fatality rate | 23.0% | 18.0% | 28.0% |
Table 12 presents the percentage reductions implied from the previous two tables if countries with no bans implemented full bans.
Table 12. Implied percentage reductions if countries with no advertising bans implement full bans
| Reduction in | Best estimate | Minimum | Maximum |
|---|---|---|---|
| Alcohol consumption | 25.2% | 16.3% | 33.6% |
| Motor vehicle fatality rate | 30.7% | 22.1% | 38.8% |
It is the view of the present authors that, for the purposes of this study, it can be assumed that Australia is a jurisdiction with effectively no advertising bans. However, for completeness of information, estimates are also provided for a move from no bans to partial bans and from partial bans to a full ban.

5.2.4 Maintaining advertising bans
Saffer and Dave (2002, p. 1,333) produce a further conclusion which has potential implications for Australian public policy towards alcohol advertising.- There is also evidence that alcohol consumption has a positive effect on total advertising bans. That is, an increase in alcohol consumption can increase the probability of legislation of an advertising ban on all forms of alcohol in a particular media. However, alcohol consumption has been trending downward in a number of countries since around 1988. These decreases may reflect changes in exogenous factors such as increases in the demand for health. This downward trend in alcohol consumption could result in a decrease in the number of advertising bans. Canada, Denmark, New Zealand and Finland recently decreased the total number of advertising bans in effect. These decreases may be examples of the difficulty in maintaining alcohol advertising restrictions when alcohol consumption is on a downward trend. Alcohol consumption in these countries may increase, or decrease at a slower rate, than would have occurred had the advertising bans remained in place.
The Saffer and Dave research indicates that, if bans on alcohol advertising lead to a reduction in alcohol consumption, there is likely to be pressure for relaxation of these bans. It is the view of the present authors that, should this occur, such pressure should be resisted. If evidence exists that bans are effective in reducing alcohol consumption, this evidence should constitute strong justification for maintaining, rather than relaxing, these controls.
