Does decentralisation promote clientelism? If yes, through whichmechanisms ? We answer these questions through an analysis of India's (and the world's) largest workfare programme, the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), in two Indian states: Rajasthan and Andhra Pradesh (AP). The two states adopted radically different implementation models: Rajasthan's decentralised one stands in contrast with Andhra Pradesh's centralised and bureaucracy-led model. Using a mixed method approach, we find that in both states local implementers have incentives to distribute MGNREGA work in a clientelistic fashion. However, in Rajasthan, these incentives are stronger, because of the decentralised implementation model. Accordingly, our quantitative evidence shows that clientelism is more serious a problem in Rajasthan than in AP.
