According to the WHO, experience with the implementation of price policies in some countries indicates that they are feasible and can influence consumption and purchasing patterns. They found, in some instances, that it has even been possible to identify a measurable impact on important dietary and health-related behaviors. Furthermore, the revenue raised has in some cases been invested in prevention and public health.
However, the report, which looks at policy in Finland, Denmark, France and Hungary among other countries, contains little new evidence on the effects of taxes. It also states that the long-term health impacts of the introduction of these taxes cannot be evaluated and that they have conducted to administrative and organizational burdens, particularly with regard to contract negotiation, logistics and reporting. In general, this new report is more a compilation of studies rather than new research.
