The Origins of Happiness
A natural tendency of skeptics is to say “But isn’t mental
illness caused by poverty or unemployment?” Some of it is.
But the equation in the table explicitly measures the im-
pact of that mental illness that is not caused by poverty or
unemployment. And in any case we have previously shown
that most mental illness is in fact not the result of poverty
or unemployment.
The Absolute Effects of Experience
As we have said, it is one thing to look at explanatory power
and another to show how changing a situation would im-
prove happiness. That is the subject of Table 16.2. It shows
how life- satisfaction (0– 10) increases as a result of various
changes. The scores recorded are points on the scale 0 to 10.

ery among adults (BHPS) (cross- section) (β- coefficients)
