Mental accounting can also be utilized in public economics and public policy. Policy-makers and public economists would do well to consider mental accounting when crafting public systems, trying to understand and identify market failures, redistribute wealth or resources in a fair way, reduce the saliency of sunk costs, limiting or eliminating the Free-rider problem, or even just when delivering bundles of multiple goods or services to taxpayers. Inherently, the way that people (and therefore taxpayer and voters) perceive decisions and outcomes will be influenced by their process of mental accounting. If policy-makers consider the implications of how people mentally book-keep their decisions, they should be able to frame and construct public policy that results in better decisions for health, wealth, and happiness.
