My PhD started with a systematic literature review to map and assess the already existing models, which simulate the health or environmental outcome of food taxes and subsidies - of those food groups mentioned in the EAT-Lancet report.
We found that none of the reviewed models could fully capture the complexity of the issue. Fiscal policies are complex. Sometimes even a seemingly good intervention can have negative effects, and missing factors can make a difference in a model that only partially simulates the intervention.
The aim of the project is to build a comprehensive model, to simulate the health and environmental impact of a food tax and subsidy package, which is directed to bring closer the population’s diet to the EAT-Lancet Commission Plenatary Health Diet.
The aim is to include health and environmental outcomes in the comprehensive model, and also to estimate the health effects deriving from the environmental change.
