Gary S. Becker

“Expectations about divorce are partly self-fulfilling because a higher expected probability of divorce reduces investments in specific capital and thereby raises the actual probability. 7 For example, consensual and trial marriages are less stable than legal marriages, and marriages between persons of different religions or races are less stable than those within a religion or race, partly because mixed marriages have fewer children. At the same time, as indicated, mixed marriages have fewer children partly because they are expected to be less stable. Specific investment and imperfect information can explain why homosexual unions are much less stable than heterosexual marriages (Saghir and Robins, 1973, pp. 56-58, 226-227). Homosexual unions do not result in children, and generally they have a less extensive division of labor and less marital-specific capital than heterosexual marriages. Moreover, the opprobrium attached to homosexuality has raised the cost of search to homosexuals and thereby has reduced the information available to them. Furthermore, homosexual unions, like trial marriages, can dissolve without legal adversary proceedings, alimony, or child support payments.”
