A structural econometric model of retirement of dual-career couples is spec
ified and estimated with panel data from the National Longitudinal Survey o
f Mature Women. A coincidence of spouses retiring together, despite the you
nger ages of wives, suggests explicit efforts at coordination. The estimate
s suggest that one reason is a correlation of tastes for leisure. More impo
rtant, each spouse, and perhaps husbands in particular, values retirement m
ore once their spouse has retired. The opportunity set accounts for peaks i
n the retirement hazards of each spouse individually but not for peaks in t
he simultaneous retirement of both spouses.
