to the actions of various actors. According to International Relations scholar Chris Brown, University of Warwick professor, Susan Strange, was "almost single-handedly responsible for creating international political economy as a field of study." In the United States, these approaches are associated with the journal International Organization, which in the 1970s became the leading journal of IPE under the editorship of Robert Keohane, Peter J. Katzenstein and Stephen Krasner. They are also associated with the journal The Review of International Political Economy. There also is a more critical school of IPE, inspired by thinkers such as Antonio Gramsci and Karl Polanyi; two major figures are Matthew Watson and Robert W. Cox. The use of a political economy approach by anthropologists, sociologists, and geographers used in reference to the regimes of politics or economic values that emerge primarily at the level of states or regional governance, but also within smaller social groups and social networks. Because these regimes influence and are influenced by the organization of both social and economic capital, the analysis of dimensions lacking a standard economic value (e.g. the political economy of language, of gender, or of religion) often draws on concepts used in Marxian critiques of capital. Such approaches expand on neo-Marxian scholarship related to development and underdevelopment postulated by André Gunder Frank and Immanuel Wallerstein. Historians have employed political economy to explore the ways in the past that persons and groups with common economic interests have used politics to effect changes beneficial to their interests. Political economy and law is a recent attempt within legal scholarship to engage explicitly with political economy literature. In the 1920s and 1930s, legal realists (e.g. Robert Hale) and intellectuals (e.g. John Commons) engaged themes related to political economy. In the second half of the 20th century, lawyers associated with the Chicago School incorporated certain intellectual traditions from economics. However, since the crisis in 2007 legal scholars especially related to international law, have turned to more explicitly engage with the debates, methodology and various themes within political economy texts. Thomas Piketty's approach and call to action which advocated for the re-introduction of political consideration and political science knowledge more generally into the discipline of economics as a way of improving the robustness of the discipline and remedying its shortcomings, which had become clear following the 2008 financial crisis.
