3. The answers are much like those demonstrated in Menkes and you may Serrano (2010), as they use a new survey.
We run t-testing on the those women having shed guidance in 2005 (sometimes destroyed or forgotten because of attrition) and you will feminine having done information there are not any extreme variations during the age, operating standing, schooling, Raven’s test get, early in the day sexual sense, and expertise in contraceptives
cuatro. Administrative beginning details is authored by the fresh new National Statistical Institute (INEGI) in Mexico therefore the Ministry away from Fitness. The information and knowledge tend to be all the births inserted so you’re able to see a birth certification. These types of management details tend to be age of mommy on delivery, studies, relationship position and area out-of birth (condition and condition). We use these suggestions so you’re able to bring a broad photo of advancement from adolescent pregnancies. Data shall be downloaded from the first-rate web site to study web websites out-of INEGI, while the Ministry out of Fitness, We explore recommendations in the seasons out-of birth as opposed to 12 months away from delivery registry. So you can calculate a series without the dilemma of right-censoring (births one took place during the last may be entered any kind of time amount of time in the long run), we limitation the information and knowledge so you can births joined just in identical 12 months together with season after the beginning season, hence represents just as much as 93% regarding births.
6. Census study never render facts about the fresh time of your own incidents, so we dont understand if maternity taken place prior to relationship otherwise cohabitation took place.

thirteen. While we explore less than, difference-in-differences prices are more legitimate than just a simple difference in medication and you will handle because they manage getting private repaired consequences and you will preferred manner between therapy and you will manage groups.
This means, we examine those with comparable propensity results or take the real difference inside the results for those people
fourteen. This is basically the techniques we pursue so you can guess the results: step 1. Guess the fresh tendency score, 2. Matches some one in line with the inclination score.
fifteen. Getting research objectives we have the results away from a simple normal minimum squares (OLS) regression. However, we highlight you to definitely PSM is preferred more regression for a few causes. Very first, PSM just takes into account observations that have quite similar values from inside the the brand new inclination get. Observations which have dissimilar beliefs commonly taken into consideration to help you calculate brand new ATT. Second, i reveal equilibrium throughout the covariates and you may preferred assistance assessment from inside the purchase to be clear towards estimate. 3rd, OLS estimators and experience the brand new curse out of multidimensionality. Finally, the latest PSM estimator does not demand as numerous limits to the useful form as OLS.
16. The process to own quoting it equation is much like Picture (2), however unlike providing variations in the newest post-therapy period, i together with take variations in this new pre-medication months.
