Research on nuclear security has gone quantitative. Rapid growth in empirical approaches to the consequences of nuclear weapons in recent years promises to settle some controversies, even as it initiates or resurrects debates that may eventually be resolved with better estimates or data. The toolkit for studying nuclear security had long been bereft of quantitative approaches, undermining the virtuous cycle between theory and evidence. New data and growing confidence in statistical approaches have finally produced a systematic empirical literature on the consequences of nuclear weapons. We review existing studies, organizing the literature along thematic lines. We also discuss challenges facing the emergent quantitative literature and suggest several avenues for future research. Although the terminus of the basic research agenda has been anticipated more than once, the literature on nuclear consequences has shown a remarkable ability to generate novel and often unexpected research questions.

Researchers continue to debate the impact of trade on interstate conflict. While many view trade as pacifying, others argue that dependencies increase friction and the risk of war. We provide a theory that explains how cross-border economic ties alternately enhance or impede international cooperation. Three main factors account for the heterogeneous effects of trade on conflict: interdependence, asymmetry, and multipolarity. Interdependence can act as a substitute for, or as a deterrent to, militarized violence. In the former case, interdependence actually increases more modest non-militarized conflict, while also discouraging militarized disputes. Asymmetry diminishes the conflict-inhibiting effect of trade ties, as dependency cannot simultaneously be used to coerce and to inform. Multilateral trade networks alternately moderate or enhance the bilateral effects of interdependence and asymmetry on interstate peace. Our theory and evidence reveal complex, cross-cutting consequences of economic interdependence on conflict behavior and also demonstrate effects well beyond the dyad, suggesting the need to include extradyadic ties in future theoretical and empirical research studying the commercial peace.

AbstractResearchers have increasingly sought to identify the social repercussions of an evolving climate. Several influential studies claim that climate change is responsible for increases in conflict, while other research finds no such evidence. Relating human-caused changes in the climate to conflict poses a basic endogeneity problem, though: accepting that industrial activity is responsible for altering the climate implies that human agency is indirectly involved in the impact of the climate on conflict. Specifically, industrial activity is closely tied to climate change and to rising economic development, the latter generally being accepted as a determinant of reductions in conflict. In this letter, we discuss this endogeneity problem, outline possible shortcomings for empirical research if this problem is not addressed, and propose a research strategy that might eventually help to overcome it effectively.
