How would Marx have understood twenty-first-century capitalism? For Buzgalin and Kolganov, the answer lies in a theoretical investigation of how and why the fundamental elements of capitalism– commodities, money and capital – have changed since the publication of Marx’s Capital more than 150 years ago. Introducing the concepts of social creativity, markets for simulacra and virtual fictitious capital – Buzgalin and Kolganov offer a recovery and development of Marx’s understanding of social transformations. Twenty-first century capitalism not only demonstrates Marxism’s relevance to the core economic questions of our time and its superiority over neoclassical economics, but it leads English-language readers into the ‘undiscovered country’ of Soviet and post-Soviet critical Marxism. How might modern Marxism respond to the contemporary challenges of the commodification of knowledge and information? And can it arrive at something resembling a Capital for the twenty-first century? This accessible and comprehensive account is essential reading for those wanting to understand the problems of the modern economy.
