... forming. Examples of possible z statistics include the number of ties, the number of ties between sixth graders, or the num- ber of triangles. The coef cients determine the impact of these statistics for a speci c set substantively different phenomena than the mutual friendships we explore...

PEBLEY We examined family and neighborhood sources of socioeconomic inequality in children s reading and mathematics achievement using data from the 2000 2001 Los Angeles Family and Neighborhood Survey. To describe inequality in achievement scores, we used Gini coef¿ cients and concentration indices...

..., the NCHS study did not control for covariates; when I do not control for covariates, premarital cohabitation does lead to increased marital instability. In addition, the coef¿ cient in 2002 without covariates is smaller than that in previous cohorts, which is the same pattern I ¿ nd for the coef¿ cients...

... coef cients for maternal employment is an instrumental variables model. Unfortunately, we were unable to identify a variable that is correlated to the endogenous variable (maternal work hours) that was plausibly independent of the error term. Given the close relationship between human capital...

..., and social capital. This situation makes it more dif¿ cult to identify coef¿ cients of migration capital variables as well as the effects of other variables (Munshi 2003; Palloni et al. 2001). Innovative empirical strategies have been used to capture variation across regions in their access to migration...

.... If X = 0 (i.e., the value of all controls is equal to zero), then is equal to the probability of death for a boy in the com- parison region. The coef cients measure differences in the probability of death across sex and area: 0 is the difference in probability of death for girls versus boys...

... fertile period. Because of this, I also estimate a version of the childbirth hazard in which the risk-tolerance variable is interacted with a spline for age, allowing different effects of risk for women younger than 20, between 20 and 29, and 30 and older.
