According to Guttentag and Secord (1983), the relative balance of powe
r between the sexes is determined by dynamic interactions of dyadic an
d structural power. Dyadic power accrues to whichever sex is relativel
y rare owing to the larger proportion of potential relationships avail
able to it, the demographic dimensions of which are commonly known as
a marriage squeeze. Structural power refers to control over economic,
political or legal resources: men or women, according to the thesis, a
ttempt to overcome existing deficits in dyadic power by gaining such r
esources. The unique dual case study presented here illuminates the st
ate political institutions and other contextual conditions under which
both dyadically disadvantaged men and women have been unable to garne
r such structural resources. Young women in Vietnam during the 1970s a
nd 1980s faced a severe deficit of male partners due to population gro
wth, war, and excess male migration. At the other end of the Vietnames
e diaspora, overseas Vietnamese men during the 1980s and 1990s have fa
ced an even greater shortage of Vietnamese women. In each area, the se
x in surplus has not only been forced to delay or forego marriage, but
has also lost structural power. Women's advocates in Vietnam have bee
n weakened in the postreunification era due in part to the implementat
ion of free market reforms in a nondemocratic political context. Overs
eas men have been disadvantaged due to a more equitable Western social
and legal climate that has eroded their former advantage.
