Rigor versus Relevance in Economic Theory: A Plea for a Different Methodological Perspective
通过分析布劳格与库尔茨等人关于斯拉法经济学相关性的争论，指出双方共享过时的科学哲学观点，并引入语义视角论证严谨性与相关性之间的权衡是经济学模型的固有特征。
A recent exchange between the late Mark Blaug and Heinz Kurz and Neri Salvadori on the relevance of Sraffian economics (and a significant amount of more orthodox approaches, for that matter) does not seem to offer conclusive arguments, mainly because both contenders share some outmoded approaches to the philosophy of science. If we instead adopt the perspective of the so-called semantic view of theories, the trade-off between rigor and relevance naturally comes out as a possible characteristic of models we encounter in many scientific disciplines, with economics not being an exception. Thus, those who argue in favor of an economic analysis both rigorous and relevant should at least have to bear the burden of the proof of its possibility.
