We all strive for personal happiness in one way or another, but what about public happiness? What does public happiness mean and what role can governments and public policies play? The current COVID-19 pandemic has highlighted the inadequacies of old governance paradigms and even before this pandemic, increasing inequalities and frustration with the old GDP-centric growth paradigm have fueled dissatisfaction with and distrust of governments. This book suggests a new path towards public happiness as a potential solution. The book builds a theory of public happiness as a distinct concept from individual happiness, borrowing especially from Eastern philosophy. It provides an overview of the efforts so far to go "beyond GDP" - including measurement and exploration of the determinants of happiness - and how these efforts have fallen short of expectation. Lastly, the book sketches out what a public happiness policy might look like and identifies the factors of a successful happiness policy.
