There have been a handful of studies about this in the US - the marginal utility of more salary =&gt; more happiness seems to slow precipitously around $70-75k USD&#x2F;yr. The last one I looked at in detail seemed pretty clear that more money still made people happier, but it took more, to the point where the gain in happiness from 60-65k was similar tot he gain in happiness from ~80k-95k.
