DORSI ABSTRACT Obesity has become a major issue in advanced societies having serious impacts on various social as well as economic levels. In addition to the personal costs of obesity leading to serious and chronic diseases, obesity projects additional burdens upon society including lack of productivity, often resulting in increased dependence on governmental benefits, as well as increasing health care costs, most of which are paid for by taxes. This phenomenon has become especially prevalent in the United States and the United Kingdom, with both countries attempting to reduce obesity levels with programs that utilize varying levels of paternalism. As the costs to these societies have become unsustainable, both have begun to experiment with behavioral insights to address the faults in their current programs. The resulting policy tool, known as a nudge, focuses on consumers’ choice environments that contribute to poor health decisions and reframes the choice structures to intuitively encourage healthier choices. While both countries continue to study the use of nudges to reduce obesity, there are large differences in how each country has utilized nudges as a policy tool. For this large-scale problem and others like it, having the resources to develop policy solutions is not enough to resolve the problem: a country must be able to properly implement the solutions for them to be effective. This paper examines the development of nudging in each country and determines whether their differences in policy application reflect a broader problem of obesity-related policy intervention. v Table of Contents Introduction .............................................................................................................................. 1 I.

While technological advances have helped these countries grow adequate amounts of food, make significant strides in scientific research, and provide strong education systems for its citizens to enjoy, the task of making sure all of these wonderful aspects of everyday life run successfully and equitably becomes very complicated. Every advance is accompanied by a set of new unanticipated problems, and often problems that the government must address these issues. For the vast majority of these problems there are numerous public opinions, and thus another problem ensues of which preferences will solve the problem and which will be implemented. The success of an industrialized country is not measured by the policy resources it has but rather by its ability to work
