Abstract:The aim of this article is to survey the huge literature that has emerged in the last four decades following Nordhaus's (1975) publication on political business cycles (PBCs). I first propose some developments in history of thought to examine the context in which this ground-breaking contribution saw the light of the day. I also present a simplified version of Nordhaus's model to highlight his key results. I detail some early critiques of this model and the fields of investigations to which they gave birth. I then focus on the institutional context and examine its influence on political business cycles, the actual research agenda. Finally, Iderive some paths for future research.
