This is the Holy Grail of economics: how does one measure and quantify happiness in people’s lives? Bhutan is so far the only country measuring economic growth in terms of gross national well-being. Its measure is not based on personal happiness, but on a set of factors that would constitute ‘wellness’ of people. The need to map happiness has acquired urgency since a panel in France led by Nobel Prize-winning economist Joseph Stiglitz came out with its happiness report in September 2009. Lola Nayar asked five leading economists whether happiness or well-being could be quantified—and whether money can buy love after all—in 2015 and beyond.
