Sociologists have much to contribute to the study of global health and development. Our discipline's fundamental concerns with power and inequality uniquely position us to leverage theoretical, conceptual, substantive, and empirical insights for the understanding of engines, outcomes, and processes of global health and development. This special issue highlights the diversity and depth of sociological engagements with the topics of global health and development. In this introduction to this special issue, I briefly outline how sociologists have approached the study of global health and development despite the fact that this is a nascent and not yet fully coalesced field. While medical sociologists and political sociologists have historically studied these topics, they have also marginalized them. Exciting sociological research is, however, underway. The challenge is in ensuring that scholarship on global health and development is in conversation across subfields in order to propel research on global health and development forward, both substantively and theoretically.

Are health care systems converging in developing nations? We use the case of health care financing in Latin America between 1995 and 2009 to assess the predictions of modernization theory, competing strands of globalization theory, and accounts of persistent cross-national differences. As predicted by modernization theory, we find convergence in overall health spending. The public share of health spending increased over this time period, with no convergence in the public-private mix. The findings indicate robust heterogeneity of national health care systems and suggest that globalization fosters human investment health policies rather than neoliberal, “race to the bottom” cutbacks in public health expenditures.
