White and Edwards (1990). Buddelmeyer, Hamermesh, and
Wooden (forthcoming) show how stress is reduced when children leave
home.
A reduction of one point- year means one point less of life-
satisfaction for one year. From Figure 9.2, (∂LS/∂LON). σLON = 0.28σLS.
For example the impact of highest qualification over 60 years
would be (7.2−0.87) point- years while that of emotional health would
be (10.8−0.04) point- years.
On the role of genes, see Chapter 12.
Of the worldwide variance of life- satisfaction across persons,
only 22% is between countries and 78% within countries (Helliwell,
Layard, and Sachs [2012], 12).
See Helliwell, Layard, and Sachs (2017), figure 2.2. Other “top”
countries include Norway, Iceland, and Switzerland, and other “low”
countries include Tanzania and Burundi.
