Petrol prices and obesity [PDF]
Health Economics (United Kingdom), 2022 AbstractUsing 13 waves of longitudinal data from Australia, we examine the relationship between petrol prices and obesity. Applying panel data models that control for individual fixed effects and the endogeneity of petrol prices, our results suggest that petrol prices have a negative effect on obesity.
