Oil-exporting states, or petrostates, engage in militarized interstate disputes (MIDs) at a much higher rate on average than nonpetrostates. Why is this so? Further, what explains the variation among the petrostates in adopting aggressive foreign policies and engaging in MIDs on that basis? This article develops a theory that proposes that revolutionary petrostates have a higher propensity to launch MIDs than comparable nonpetrostates. This theory is tested with statistical analysis using a new quantitative data set that identifies revolutionary governments in the period 1945–2001. The results show that petro-revolutionary governments constitute a special threat to international peace and security. This evidence of resource-backed aggression challenges the conventional view of petrostates as the targets of international competition for resources.

The concept of a regime complex has proved fruitful to a burgeoning literature in international relations, but it has also opened up new questions about how and why they develop over time. This article describes the history of the energy regime complex as it has changed over the past forty years, and interprets this history in light of an interpretive framework of the sources of institutional change. One of its principal contributions is to highlight what Stephen Krasner referred to as a pattern of "punctuated equilibrium" reflecting both periods of stasis and periods of innovation, as opposed to a gradual process of change. We show that the timing of innovation depends on dissatisfaction and shocks and that the nature of innovation—that is, whether its path-dependent or de novo—depends on interest homogeneity among major actors. This paper is the first to demonstrate the empirical applicability of the punctuated equilibrium concept to international regime complexes, and contributes to the eventual development of a dynamic theory of change in regime complexes

Whereas scholars have typically modeled climate change as a global collective action challenge, we offer a dynamic theory of climate politics based on the present and future revaluation of assets. Climate politics can be understood as a contest between owners of assets that accelerate climate change, such as fossil fuel plants, and owners of assets vulnerable to climate change, such as coastal property. To date, obstruction by “climate-forcing” asset holders has been a large barrier to effective climate policy. But as climate change and decarbonization policies proceed, holders of both climate-forcing and “climate-vulnerable” assets stand to lose some or even all of their assets' value over time, and with them, the basis of their political power. This dynamic contest between opposing interests is likely to intensify in many sites of political contestation, from the subnational to transnational levels. As it does so, climate politics will become increasingly existential, potentially reshaping political alignments within and across countries. Such shifts may further undermine the Liberal International Order (LIO); as countries develop pro-climate policies at different speeds and magnitudes, they will have incentives to diverge from existing arrangements over trade and economic integration.

Gender diversity is good for the study of international relations (IR) and political science. Graduate training is an opportunity for scholars to affect the demographics of their field and the gendered practices within it. This article presents a first-cut investigation of the degree to which gender bias exists in graduate IR syllabi. The author found that the gender of the instructor for graduate courses matters significantly for what type of research is taught, in two ways. First, on average, female instructors assign significantly more research by female authors than male instructors. Second, women appear to be considerably more reluctant than men about assigning their own research as required readings. Some but not all of the difference between male- and female-taught courses might be explained by differences in course composition.
