Causes of the Obesity Epidemic and Economic Rationales to Support Taxation as a Population-based Policy Response

This article examines the diverse and sometimes debatable underpinning causes of the growing obesity epidemic both in Australia and globally in order to provide a background that supports and legitimises the implementation of population-based strategies to address the associated negative impacts for both individuals and broader society. Particular focus is given to the consumption of Highly Processed Foods, and Sweetened Sugary Beverages, and the impact that the over-consumption of these products has on obesity and overweight issues. In order to address and mitigate against the negative consequences that emanate from the consumption of such products for both individuals and for broader society, taxation, as one population-based initiative that policymakers can implement is explored by reference to economic based theories. These include the Consumer Choice Constraint Theory, the Indifference Curve approach and the Pigouvian Theory of taxation. These economic theories provide a supportive basis upon which policymakers can effectively implement such an approach.
