While growth in India stayed relatively stable over the last decade, Brazil fell into deep recession and a fundamental political and economic crisis. Why did these two countries, despite their similarities, diverge so massively within only 10 years? Through a paired comparison, this article probes two alternative approaches to capitalist diversity to explain the divergence among two rising economic powers and ‘state capitalisms’. It finds that through the lens of a firm-centred supply-side approach, one largely sees institutional stability in both economies, while a focus on the demand side and respective growth models makes visible fundamental destabilization in Brazil. The fragility of domestic demand, the vulnerability of global economic integration and the erosion of key social coalitions, we contend, are key to unpack the divergence between Brazil and India. This study thereby not only sheds a new light on emerging market capitalism but also discusses further possibilities for the analysis of state capitalism within comparative political economy.
