The family income distributions of NLSY97 and CPS youth data are compared by using the generalized beta distribution of the second kind. The null hypothesis that the two data sets represent the same underlying population is rejected. The ML estimation suggests that NLSY97 data are oversampled in an income group of $11,308 or less, by about 15.7% compared to CPS data.

Data from the National Longitudinal Study of Youth (NLSY) were used to examine factors related to adolescent behavior problems, smoking, and delinquency. This study focuses particularly on the factors in an adolescent s immediate environment such as family, school, peers, and neighborhood (i.e. the microsystems) for the identification, prevention, and early intervention of adolescent behavior problems, smoking, and delinquent behavior. Both African American and Caucasian American adolescents between the ages of 13 and 17 for whom data were available in the NLSY were included in this study (N=788). Results indicate that delinquent peer pressure and negative attitudes toward school are important determinants of behavior problems, smoking, and delinquency of American adolescents. Differences between African American and Caucasian American adolescents are highlighted.

This paper examines the differences between the subsequent careers of high school and college graduate workers based on a direct role of college graduation with regard to the revelation of workers' individual abilities. Using NLSY79, we document a positive relationship between off-the-job training/performance-pay jobs and ability for high school graduates at the early stages of their careers. However, this relationship is less prominent for college graduates. Moreover, we show that high ability is associated with more jobs, which reflects higher job mobility, only for high school graduates. We argue that these patterns are the result of productivity-revealing behavior of high school graduates, whose individual abilities, unlike college graduates, is not observed precisely at the beginning of their careers.

On the basis of data from the National Longitudinal Survey of Youth (NLSY), this paper investigates wage consequences of cumulative experience of job displacement. Unlike previous studies, we consider two measures of cumulative unemployment experience simultaneously: the total frequency and the cumulative duration of unemployment induced by job displacement. When frequency and cumulative duration compete in a wage equation, only cumulative duration remains significant for men, while only frequency matters for women. For men, a one-month increase in the cumulative duration of displacement-initiated unemployment leads to a fall in wages by 0.4 percent. This finding is quite robust with respect to various sample restrictions and/or estimation methods. For women, approximately a 2.5 percent wage reduction is associated with an additional event of displacement.

In research on behavioral studies, significant attention has been paid to the stage-sequential process for multiple latent class variables. We now explore the stage-sequential process of multiple latent class variables using the multivariate latent class profile analysis (MLCPA). A latent profile variable, representing the stage-sequential process in MLCPA, is formed by a set of repeatedly measured categorical response variables. This paper proposes the extended MLCPA in order to explain an association between the latent profile variable and the latent group variable as a form of a two-dimensional contingency table. We applied the extended MLCPA to the National Longitudinal Survey on Youth 1997 (NLSY97) data to investigate the association between of developmental progression of depression and substance use behaviors among adolescents who experienced Authoritarian parental styles in their youth.

일반적으로 인구이동은 전형적인 연령패턴을 갖는 것으로 알려져 있다. 연령에 따른 이동률의 변화는 생애주기와 지역애착에 영향을 받기 때문이라고 설명되어왔다. 많은 인구이동 연구들은 인구이동이 갖는 다양한 형태에 대한 고민 없이 단순한 거주지역의 변화에만 초점을 맞추었다. 하지만 인구이동의 다양성에 주목한 연구들은 인구이동이 그 형태에 따라 다양한 의미를 갖고 있음을 보여주고 있다. 이에 이 연구는 패널데이터(NLSY79)를 사용하여, 인구이동을 최초이동, 계속이동 및 귀환이동으로 구분하였다. 이러한 구분을 바탕으로 생애주기 및 지역애착 등을 반영하는 사회경제적 변수들을 통제한 후 연령이 인구이동에 미치는 영향을 알아보았다. 분석결과는 인구이동이 그 형태에 따라 다양한 연령패턴을 갖는다는 것을 보여준다. 최초이동은 이동률이 성인초기 연령대의 매우 높은 수준에서 급감하여 중년에 이르러 일반적 이동률 수준으로 나타났고, 계속이동은 연령의 증가에 따라 선형으로 꾸준히 감소하지만 그 폭은 크지 않았다. 그러나 귀환이동은 이동률이 연령에 따라 증가하는 모습을 보여주었다. 이러한 연령패턴의 다양성을 설명을 위해 이 연구는 인구이동에서의 보수성 증가라는 심리적 접근을 제안하고 있다.

We investigate the latent stage-sequential patterns of drinking behaviors of U.S. adolescents who have started to drink by age 14 years (seven years before the legal drinking age). A multiple-group latent transition analysis(LTA) with logistic regression is employed to identify the subsequent patterns of drinking behaviors among early-onset drinkers. A sample of 1407 early-onset adolescents from the National Longitudinal Survey of Youth(NLSY97) is analyzed using maximum-likelihood estimation. The analysis demonstrates that early-onset adolescents' drinking behaviors can be represented by four latent classes and their prevalence and transition are influenced by demographic factors of gender, age, and race.

Using samples of working mothers with 0-to-47 month old children extracted from the National Longitudinal Survey of Youth (NLSY), this study investigated effects of mothers' job characteristics on parenting behaviors and young children's motor, social, and cognitive development. Date were analyzed by descriptive statistics and multiple regression analysis. Results indicated that (1) job dissatisfaction was negatively related to children's development. (2) Working fewer hours was positively associated with mothers' cognitively stimulating parenting behaviors. (3) Total earnings were a positive predictor of mothers' emotional support. (4) The availability of a flexible hour benefit was positively related to mothers' cognitive stimulation level but the availability of a paid sick and vacation days combined benefit was negatively related to mothers' cognitively stimulating parenting behavior.

This research studies how women's hourly wages affect childbearing using data from the National Longitudinal Survey of Youth. The results of discrete time hazard model show that the relationship between women's hourly wage and fertility is dynamic. Overall relationship looks negative, but they are not consistent across education levels. Women who have a high school diploma or less have a tendency to decrease childbearing when their wages increase. But women who have some college experience or a college degree are likely to have children when their wages increase. It means that only for highly educated women who are likely to be in high paying decent jobs, the rise of income can be used as a resource for reconciling the mother's and worker's roles. Or, for less educated women who are likely to be in the low paying jobs, the rise of income is not large enough to lessen role incompatibility.
