Harvard Business Review, Mar2007: Ideally, businesses improve lives by creating things people want. At the very least, companies produce wealth (which, at the individual level, is an imperfect but passable proxy for happiness). So businesses should be interested in this map, developed by Adrian G. White, a social psychologist at the University of Leicester, which shows the global distribution of happiness. White combined data from more than 100 studies involving 80,000 people worldwide to gauge countries' "subjective well-being" - which, he found, correlates most strongly with health, wealth, and access to basic education, in that order. White's map suggests regions that need more of what companies do best (for further details, see here).
