Economic analyses and modelling can influence the
development of public health policy by providing evidence
about the economic impact of different policies and the return
on investment for policy changes, as well as any differential
outcomes arising from policy implementation. Such
analyses can also provide data relevant to broader factors
that impact on policy decisions.
This article describes the use of an economic analysis of
a reduction in smoking prevalence to counter competing
claims of industry interest groups, and to identify the
potential beneficiaries of tighter tobacco control policies.
