Trade liberalization and child mortality: a synthetic control method

We study the causal effect of trade liberalization on child mortality by exploiting 41 policy reform experiments in the 1960-2010 period. The Synthetic Control Method for comparative case studies allows to compare at the country level the trajectory of post-reform health outcomes of treated countries (those which experienced trade liberalization) with the trajectory of a combination of similar but untreated countries. In contrast with previous findings, we find that the effect of trade liberalization on health outcomes displays a huge heterogeneity, both in the direction and the magnitude of the estimated effect. Among the 41 investigated cases, 19 displayed a significant reduction in child mortality after trade liberalization. In 19 cases there was no significant effect, while in three cases we found a significant worsening in child mortality after trade liberalization. Trade reforms in democracies, in middle income countries and which reduced taxation in agriculture reduce child mortality more.status: publishe
