  1. The Effect of Older Siblings on Adolescent Behavior: Is It Siblings or is it Parents? Laura Argys Department of Economics University of Colorado at Denver Susan Averett Department of Economics and Business Lafayette College Daniel Rees Department of Economics University of Colorado at Denver

  2. Birth Order and Parental Supervision Price (2005) Only study to examine parental time and birth order Uses data from American Time Use Survey Finds that parents spend 20-30 minutes less per day with later-born children.

  3. Parental Supervision and Child Behaviors Parental (Maternal) work and cognitive outcomes in young children Leibowitz (1977), Blau and Grossberg (1992), Brooks-Gunn, Han and Waldfogel (2002) Parental supervision and risky behaviors substance use – Richardson et al. (1993) behavior problems – Vandall and Ramanan (1991) substance use, theft, truancy – Aizer (2004)

  4. Research Objectives To confirm the existence of a birth-order effect on risky behaviors. To disentangle the effect of: • Parents differential supervision of children by birth-order • Siblings initiation modeling

  5. Previous Empirical Findings on Economic Outcomes Birth order and Education Olneck and Bill, 1979 No Blake, 1981 No Hauser and Sewell, 1983 No Behrman and Taubman, 1986 Yes Birth order and Earnings Olneck and Bill, 1979 No Behrman and Taubman, 1986 No Kessler, 1991 No Sex Composition Butcher and Case, 1994 Yes Kaestner, 1997 No Hauser and Kuo, 1998 No

  6. Previous Empirical Findings on Other Outcomes Birth order on age at first intercourse Rodgers st al., 1992 Older sibling graduation on younger sibling’s graduation Oettinger, 2000 Older brother characteristics on drug use Brook et al., 1991 Older sibling sexual behavior on sexual initiation Widmer, 1997 Haurin and Mott, 1990 Older sibling behavior on substance use Ouyang, 2004

  7. Eq.(1) R * i S i F i X i Model = An individual’s propensity to engage in a particular risky activity = A dichotomous variable indicating an older sibling = A vector ofcontrols for family size = Other individual and family characteristics

  10. Data National Longitudinal Survey of Adolescent Health Over 20,000 adolescents In grades 7-12 in 1995 Household roster and family structure Risk-taking activities Family background Parental Supervision

  11. Conclusions The existence of an older sibling: Increases the probability of cigarette, alcohol and marijuana use Increase the probability of sexual activity for males Has no consistent effect on other delinquent behaviors Parental Supervision is slightly lower for: boys with an older sibling girls with an older sister Parental Supervision: reduces risky behaviors does not explain the effect of an older sibling.
