Increases in Net Worth and DivorceMike Rappaport

Even though divorce rates are declining over all, as far back as 1977the economist Gary Becker showed that couples experiencing anyunexpected, drastic rise in net worth are at risk of divorce. (The sameholds true for a drastic decline in net worth.)

From the New York Times, as noted by Tyler Cowan.

That drastic declines in net worth lead to divorces is sad, but it does not make you cynical about the basis of marriages.  That “unexpected drastic rises in net worth” result in divorces does.
