Is Learning better than Taxation 1: Université Paris-Saclay, INRAE, PSAE; 2: Université Gustave Eiffel, ERUDITE The global rise in obesity, together with the food system’s substantial contribution to greenhouse gas (GHG) emissions, underscores the need for effective government intervention. This paper develops an overlapping generations (OLG) model to analyze the long-term public health and environmental impacts of a school canteen policy that promotes sustainable meals. We show theoretically that, relative to a food tax, school meal policy can generate higher welfare. Importantly, school meal policy is not a substitute for food taxation but can act as an additional policy instrument. Indeed, while the school canteen policy shapes dietary habits from childhood, the food tax policy has a more instantaneous impact on consumption of unhealthy foods. Numerical simulations calibrated to French data confirm that a school meal policy may outperform a food tax in terms of welfare. To the best of our knowledge, this paper is the first theoretical contribution to explicitly analyze a school meal policy within a unified framework of health and environmental externalities, and intergenerational welfare. | |
