Somewhere in between unipolar and imperial orders, hegemonies divide the continuum from anarchy to hierarchy in world politics, connoting interstate systems of the highest concentration of authority. However, depending on the author, hegemony might denote the concentration of relative capabilities in a single state, the presence of a state that seeks international leadership, general consent in the international society regarding subordination to a central order, or a combination of these phenomena. Similarly, scholars debate the extent to which the relation of authority entailed by hegemony should encompass the economic, military, and/or ideational domains. Given this multiplicity of meanings, this review of extant definitions illuminates some issues that must be addressed explicitly when dealing with this concept. Although hegemony might mean different things for different intellectual traditions, these understandings are interconnected in a family resemblance structure that has facilitated mutual intelligibility. A mapping of this network of meanings suggests that special attention needs to be paid to how scholars have thought about the capabilities that would-be hegemons have, the roles they play, and the type of response they elicit from subordinate states. It also suggests the economic, military, and ideational dimensions of hegemony should be explicitly considered in theoretical discussions. Finally, it highlights the importance of avoiding ambiguity by connecting theory with empirics and providing clear measurement strategies. Measurement is essential to delineate the geographical and temporal scope of hegemonies with more precision, to compare them, and to evaluate their effects on certain outcomes. Debates about hegemony have undergone important empirical progress throughout the decades rendering this a promising area for future research.

The political economy of violent conflict is a body of literature that investigates how economic issues and interests shape the dynamics associated to violent conflict after the Cold War. The literature covers an area of research focusing on civil wars—the predominant type of conflict in the 1990s and early 2000s—and an area of research focusing on other types of violent conflict within states, such as permanent emergencies, criminal violence, and political violence associated to turbulent transitions. The first area involves four themes that have come to characterize discussions on the political economy of civil wars, including research on the role of greed and grievance in conflict onset, on economic interests in civil wars, on the nature of conflict economies, and on conflict financing. The second area responds to the evolution of violent conflict beyond the categories of “interstate” or “civil” war and shows how political economy research adapted to new types of violent conflict within states as it moved beyond the “post-Cold War” era. Overall, the literature on the political economy of violence conflict emphasizes the role of informal systems behind power, profits and violence, and the economic interests and functions of violence underlying to violent conflict. It has also become a conceptual laboratory for scholars who after years of field research tried to make sense of the realities of authoritarian, violent or war-affected countries. By extending the boundaries of the literature beyond the study of civil wars after the Cold War, political economy research can serve as an important analytical lens to better understand the constantly evolving nature of violent conflict and to inform sober judgment on the possible policy responses to them.
