Track 8: From evidence to policy

Policy-making should be based on strong quantitative evidence about the effectiveness, the efficiency (i.e. the cost-effectiveness) and the distributional impact of any new action. This is particularly important in the assessment of complex interventions with long-term outcomes as in the case of policies addressing healthrelated behaviours and other individual exposures. Based on the longstanding experience of the OECD Health Division in providing policy advice to governments, this presentation will highlight the main issues that researchers should take into account in producing health economic data on unhealthy behaviours linked with obesity. Through concrete examples, the presentation will first highlight the main gaps in current data availability (e.g. insufficient use of objective measurement systems, scarcity of data on the long-term effectiveness of policies). Second, it will review strengths and limitations of the most common simulation tools employed to produce quantitative evidence. Third, it will outline the key economic dimensions to be included in any economic assessment of prevention policies to tackle obesity and related chronic diseases. The presentation will end with a case for a wider use of computer simulation approaches and the standard inclusion of analyses on how health programmes may impact other key areas of policymaking as the labour market, trade and the wider economy.
