The king of Bhutan wants to make us all happier. Governments, he says, should aim to maximize their people’s Gross National Happiness, rather than their Gross National Product (GNP). Does this new emphasis on happiness represent a shift or just a passing fad?
It is easy to see why governments should de-emphasize economic growth when it is proving so elusive. The eurozone is not expected to grow at all this year. The British economy is contracting. Greece’s economy has been shrinking for years. Even China is expected to slow down. Why not give up growth and enjoy what we have?
No doubt this mood will pass when growth revives. Nevertheless, a deeper shift in attitude toward growth has occurred.
The first factor to undermine the pursuit of growth was concern about its sustainability. Can we continue growing at the old rate without endangering our future?
When people started talking about the “natural” limits to growth in the 1970s, they meant the impending exhaustion of food and non-renewable natural resources. Recently, the debate has shifted to carbon emissions. As the Stern Review on the Economics of Climate Change of 2006 emphasized, we must sacrifice some growth today to ensure that we do not all fry tomorrow.
Curiously, the one taboo area in this discussion is population. The fewer people there are, the less risk we face of heating up the planet. However, instead of accepting the natural decline in their populations, rich-country governments absorb an increasing number of people to hold down wages and thereby grow faster.
A more recent concern focuses on the disappointing results of growth. It is increasingly understood that growth does not necessarily increase our sense of well-being. So why continue to grow?
The groundwork for this question was laid some time ago. In 1974, the economist Robert Easterlin published a famous paper, Does Economic Growth Improve the Human Lot? Some Empirical Evidence. After correlating per capita income and self-reported happiness levels across a number of countries, he reached a startling conclusion: probably not.
Above a low level of income, Easterlin found no correlation between happiness and GNP per head. In other words, GNP is a poor measure of life satisfaction.
That finding reinforced efforts to devise alternative indexes. In 1972, economists William Nordhaus and James Tobin formulated the “Net Economic Welfare” measure by deducting from GNP “bad” outputs, like pollution, and adding non-market activities like leisure. They showed that a society with more leisure and less work could have as much welfare as one with more work — and therefore more GNP — and less leisure.
Recent metrics have tried to incorporate a wider range of “quality of life” indicators. The trouble is that you can measure quantity of stuff, but not quality of life. How one combines quantity and quality in an index of “life satisfaction” is a matter of morals, not economics, so most economists stick to quantitative measures of “welfare.”
However, another finding has also started to influence the current debate on growth: Poor people within a country are less happy than rich people. Above a low level of sufficiency, happiness is determined much less by peoples’ absolute income than by their income relative to some reference group. We constantly compare our lot with that of others, feeling either superior or inferior, whatever our income level. Well-being depends more on how the fruits of growth are distributed than on their absolute amount.
