The Lesson from America: US Politics and recent trends in contemporary political economies

US politics is living a tense period of transformation. Approaching the presidential elections of 2024, many commentators question the fate of the US representative democracy and its political system. Political scientists have largely contributed to the critical analysis of the US case. A special mention goes to Jacob Hacker and Paul Pierson. The two scholars have marked the last two decades of US political science with a brilliant reconstruction of the American crisis and some of its key trends: the progressive increase of inequality; the mounting role of business lobbies; the decline of the US political economy and the erosion of the federal institutions. The present research note reviews three key books that shed light on contemporary US political economy through a typical political science approach. The value of these books goes well beyond the originality of the analysis of US politics. The books remind us the importance of three theoretical domains that marked political science and that merit to be further developed: interest group theory, neo-institutionalism and historical theories of democratization. Then, they shed light on the current dramatic tensions over representative democracies, well beyond the US exceptionalism. Hacker and Pierson provide an illuminating analysis of democratic tensions and give insights for the future research agenda of scholars of western political economies (including Italy and Europe). The books eventually outline some interesting methodological lines of future research.
