It was a rare case of a monarch’s unilaterally stepping back from power, and an even rarer case of his doing so against the wishes of his subjects. He gave the throne to his son, Jigme Khesar Namgyel Wangchuck, who was crowned in November in the new role of constitutional monarch without executive power.

Bhutan is, perhaps, an easy place to nimbly rewrite economic rules — a country with one airport and two commercial planes, where the east can only be reached from the west after four days’ travel on mountain roads.

No more than 700,000 people live in the kingdom, squeezed between the world’s two most populous nations, India and China, and its task now is to control and manage the inevitable changes to its way of life. It is a country where cigarettes are banned and television was introduced just 10 years ago, where traditional clothing and architecture are enforced by law and where the capital city has no stoplight and just one traffic officer on duty.

If the world is to take gross national happiness seriously, the Bhutanese concede, they must work out a scheme of definitions and standards that can be quantified and measured by the big players of the world’s economy.

“Once Bhutan said, ‘O.K., here we are with G.N.H.,’ the developed world and the World Bank and the I.M.F. and so on asked, ‘How do you measure it?’ ” Mr. Dorji said, characterizing the reactions of the world’s big economic players. So the Bhutanese produced an intricate model of well-being that features the four pillars, the nine domains and the 72 indicators of happiness.

Specifically, the government has determined that the four pillars of a happy society involve the economy, culture, the environment and good governance. It breaks these into nine domains: psychological well-being, ecology, health, education, culture, living standards, time use, community vitality and good governance, each with its own weighted and unweighted G.N.H. index.
