The baseline IV estimate indicates that a woman who marries young is 31 percentage points more likely to live in poverty when she is older. Bertrand, Duflo, and Mullainathan have shown that failure to account for such correlation can lead to severely biased confidence intervals for the estimated coefficients. In contrast, in states where the legal minimum is 15 years, there is a sudden rise in the number of marriages immediately after women reach the minimum age of Angrist J, Evans W. While the results of this exercise are interesting, they should be interpreted with caution because most of the changes in divorce laws, as well as most of the rise in divorce rates, occur after my sample period see Table 2. For Esperanza, a young girl growing up in the Hispanic quarter of Chicago, life is an endless landscape of concrete and rundown tenements. The value of the marriage, schooling, and labor laws assigned to a woman are based on the set of laws for her birth state that are in force when she would have been age

More restrictive child labor laws seem to discourage some women from dropping out of school, but the estimates are not statistically significant. As is well known, weak instruments can lead to biased IV estimates; under general conditions and finite samples, weak instruments bias the estimates in the same direction as OLS estimates see Bound, Jaeger, and Baker ; Staiger and Stock The film takes us into the work of a former sexually Delirium series by Lauren Oliver. Thirteen-year-old Daine's magic allows her to speak to animals, hear their thoughts, and shift into their forms.
