Contemporary, technoscientific capitalism is characterized by the configuration of a range of “things” as assets or capitalized property. Accumulation strategies have changed as a result of this assetization process. Rather than entrepreneurial strategies based on commodity production, technoscientific capitalism is increasingly underpinned by rentiership or the appropriation of value through ownership and control rights, monopoly conditions, and regulatory or market devices and practices. While rentiership is often presented as a negative phenomenon in both neoclassical and Marxist political economy literatures—and much (...) in between—in this paper, I conceptualize rentiership as a technoeconomic practice and process framed by insights from science and technology studies. So, rather than a problematic “side effect” of capitalism, the concept of rentiership enables us to understand how different forms of value extraction constitute, and are constituted by, different forms of technoscience. This allows STS to contribute a distinctive analytical approach to ongoing debates in political economy about economic rents and rent-seeking. (shrink)
