dc.descriptionAprovechamos el brote de Zika en Colombia en 2015 para explorar cómo un choque negativo -que pone en alto riesgo la salud del recién nacido- afecta los comportamientos femeninos asociados a la fertilidad, según su estado civil. La posible endogeneidad de los comportamientos y el inicio del brote se evita mediante el uso de la estrategia de variables instrumentales en el contexto de una diferencia en diferencias con intensidad de tratamiento a nivel de municipio. Mientras que las mujeres solteras reducen la actividad sexual (el margen extensivo), las casadas no lo hacen; en cambio, las casadas aumentan la anticoncepción tanto en el margen extensivo como en el intensivo (sustituyen los métodos menos eficaces por otros más eficaces). Este resultado está en consonancia con un modelo de riesgo moral de las decisiones sobre la fecundidad en la pareja. Según el modelo, el hecho de no tener un hijo puede agredir al marido y éste puede, a su vez, convertirse en un marido "difícil". En ese modelo, la epidemia de ZIKV aumenta el uso de la anticoncepción de la mujer y reduce la probabilidad de que el hombre tome represalias. No se observan efectos significativos en la violencia intrafamiliar ejercida por los hombres (es decir, violencia física y psicológica o relaciones sexuales forzadas) ni reducciones en la proporción de los gastos realizados por las mujeres. Encontramos que los maridos de las mujeres mayores tienen menos probabilidades de tener otras parejas sexuales. Los efectos son heterogéneos en función de los grupos de edad y el nivel de educación.spa
dc.description.abstractWe exploit the Zika outbreak in Colombia in 2015 to explore how a negative shock that puts at high risk the newborn's health affects female behaviours associated with fertility, according to their marital status. The potential endogeneity of behaviours and the outbreak onset is avoided by using instrumental variables strategies in the context of an intensity-of-treatment difference-in-differences at the municipality level. While single women reduce sexual activity (the extensive margin), married women do not; instead, married women increase contraception in both the extensive margin and the intensive margin (they substitute less effective methods for more effective ones). This result is in line with a moral hazard model of fertility decisions within the couple. According to the model, not having a child may aggrieve the husband, and he may, in turn, become a "difficult" husband. In such a model, the ZIKV epidemic increases the use of women's contraception and reduces the likelihood of men's retaliation. We find no significant effects on intra-household violence exerted by men (i.e. physical and psychological violence or forced sex) nor reductions in the proportion of expenditures made by women. We do find that husbands of older women are less likely to have other sexual partners. There are heterogeneous effects across age groups and education level.spa
