IZA DP No. 6175: The French Unhappiness Puzzle: The Cultural Dimension of Happiness
published as 'Why are the French so Unhappy? The Cultural Dimension of Happiness' in: Journal of Economic Behavior and Organization, 2014, 106, 379-401.
This article sheds light on the important differences in self-declared happiness across countries of equivalent affluence. It hinges on the different happiness statements of natives and immigrants in a set of European countries to disentangle the influence of objective circumstances versus psychological and cultural factors. The latter turns out to be of non-negligible importance in explaining international heterogeneity in happiness. In some countries, such as France, they are responsible for 80% of the country's unobserved idiosyncratic source of (un-)happiness.
