This paper explores how the responsibility of caring for children affects e
mployment stability by studying the relationship between the characteristic
s and stability of substitute caregivers and the risk of leaving of job. Th
e data come from the 1990 National Child Care Survey (NCCS), a nationally r
epresentative survey of households with children under age 13 conducted in
late 1989 and early 1990, and A Profile of Child Care Settings (PCS), a nat
ionally representative survey of center-based programs and licensed family
day care homes in the U.S,, conducted at the same time and in the same 144
counties. The results show that the availability of care affects the job st
ability of all employed mothers. Other effects differ by maternal wage. The
cost of care affects the employment exits of moderate-wage mothers (who ea
rn $6 to $8 per hour), the stability of care affects the employment exits o
f moderate- and high-wage mothers, and the flexibility of care affects the
employment exits of low-wage mothers. These results are discussed in the co
ntext of current public policies.
