A study focused on the extent to which women undergo a spell of unemployment upon reentering the labor force and the factors that determine whether they undergo this spell of unemployment. Data were from two samples of female reentrants constructed from the National Longitudinal Survey for 1972. The sample of young women included those 20-28 years of age, and the sample of mature women included persons 35-49 years of age. A search model was used to examine reentrant behavior and the probability that this will lead to a spell of unemployment. Results showed that only one of every three women undergoes a period of unemployment upon reentrance. Determinants considered included education, certification, work experience, marital status, young children at home, migration, potential market wage, race, unemployment rate, and prior intentions to seek work. The significant variables for the mature women indicated the importance of flows of labor market information (education and work experience) and the importance of prior decision making in formulating plans for reentrance. Significant variables for young women came from the information vector (certification, work experience, migration) and prior search plans. Also significant were the variables of number of children at home and race. (YLB)
