Cross-disciplinary intersections between public health and economics in intimate partner violence research

Research on intimate partner violence (IPV) has progressed in the last decade in the fields of public health and economics, with under-explored potential for cross-fertilisation. We examine the theoretical perspectives and methodological approaches that each discipline uses to conceptualise and study IPV and offer a perspective on their relative advantages. Public health takes a broad theoretical perspective anchored in the socio-ecological framework, considering multiple and synergistic drivers of IPV, while economics focuses on bargaining models which highlight individual power and factors that shape this power. These perspectives shape empirical work, with public health examining multi-faceted interventions, risk and mediating factors, while economics focuses on causal modelling of specific economic and institutional factors and economic-based interventions. The disciplines also have differing views on measurement and ethics in primary research. We argue that efforts to understand and address IPV would benefit if the two disciplines collaborated more closely and combined the best traditions of both fields. •Public health and economics take different approaches to IPV research.•Public health has a broad, multi-level theoretical lens, analysing risk pathways.•Economics focuses on individualistic causal models and analysis of causal impacts.•Disciplinary differences also include ethical and measurement considerations.•Increased inter-disciplinary research will facilitate global efforts to end IPV.
