The SraffianMethodenstreitand the revolution in economic theory
回应辛哈的著作《经济理论革命》，聚焦斯拉法贡献中的方法论问题，探讨其几何方法、与维特根斯坦的关联，以及理论与历史在斯拉法分析争议中的作用。
Here I address several questions raised by Ajit Sinha’s book A Revolution in Economic Theory: The Economics of Piero Sraffa. I focus on the contribution brought by the book, and the way in which it is positioned against other contributions, especially in what concerns the methodology presupposed in Sraffa’s contribution, within what can be termed a Sraffian Methodenstreit, given the role of theory and history in the controversies surrounding Sraffian analysis. In so doing, I address the geometrical approach advanced by Sraffa, which is emphasised by Sinha in his critique of interpretations of Sraffa drawing on the notion of equilibrium. I also address the connections between Sraffa and Ludwig Wittgenstein, which are discussed by Sinha, taking into special consideration what Wittgenstein saw as Sraffa’s ethnological or anthropological approach, and its implications for the use of Sraffa’s methodology in economics.
