July 2019Effect of an Abrupt Change in Sexual and Reproductive Health Policy on Adolescent Birth Rates in Ecuador, 2008–2017
with Jeffrey E. Harris: w26044
In recent years, several countries have implemented restrictive, abstinence-only policies toward reproductive health, as opposed to comprehensive, adolescent-friendly health services. Little is known, however, about the effects of these restrictive policies on adolescent birth rates at the national level or their differential effects by race and ethnicity. The extant literature is even scarcer in low- and middle-income countries. We fill this knowledge gap by exploiting an unexpected policy change in Ecuador that abruptly reversed course for reproductive health services for adolescent women in 2014. In a difference-in-differences analysis of age-specific birth rates in Ecuador’s 221 cantons, we find that the abrupt policy change was associated with an increase in teen birth rates by 9 birt...
October 2007Heterogeneous Impact of the "Seguro Popular" Program on the Utilization of Obstetrical Services in Mexico, 2001-2006: A Multinomial Probit Model with a Discrete Endogenous Variable
with Sandra G. Sosa-Rubi, Jeffrey E. Harris: w13498
Objective: We evaluated the impact of Seguro Popular (SP), a program introduced in 2001 in Mexico primarily to finance health care for the poor. We studied the effect of SP on pregnant women's access to obstetrical services. Data: We analyzed the cross-sectional 2006 National Health and Nutrition Survey (ENSANUT), focusing on the responses of 3,890 women who delivered babies during 2001-2006 and whose households lacked employer-based health care coverage. Methods: We formulated a multinomial probit model that distinguished between three mutually exclusive sites for delivering a baby: a health unit accredited by SP; a clinic run by the Department of Health (Secretaria de Salud, or SSA); and private obstetrical care. Our model accounted for the endogeneity of the household's binary decis...

October 2006An Instrumental Variable Evaluation of Antidepressant Use on Employment Among HIV-Infected Women Using Highly-Active Antiretroviral Therapy in the United States: 1996-2004
with David S. Salkever, Judith A. Cook, Stephen J. Gange: w12619
This paper examines the effect of antidepressant use on the likelihood of being employed among HIV-positive women receiving highly active antiretroviral therapy (HAART) in the United States from 1994 to 2004. We use instrumental variables to predict antidepressant use independently of outcomes; thus, addressing potential sources of bias -- more depressed women are more likely to receive antidepressant treatment, but they are also more likely to be unemployed. The results show that antidepressant use has a positive effect on the employment probability of women living with HIV. The proposed instrumental variables can be used to identify antidepressant use in the WIHS population. Among women receiving HAART, and controlling for individual and local area labor market characteristics, the u...
