The Interplay Between Mainstream and Marxist Economists

The relationship between mainstream and Marxist economists is complex and often contentious. While mainstream economists generally use mathematical models and focus heavily on market phenomena, Marxist economists offer a radically different framework, rooted in historical materialism and the labor theory of value. Understanding this interplay is crucial for appreciating the evolution of economic thought and the myriad perspectives that shape modern economic analysis.

Evolution of Mainstream Economics

Mainstream economists, often associated with neoclassical economics, train in rigorous mathematical models and market analysis. Figures like Alfred Marshall at the University of Cambridge trained the likes of Joan Robinson, who would later challenge the paradigms of mainstream economics. Robinson's work is a compelling example of how even the staunchest adherents of mainstream economics can question and critique their own methodologies and theories.

Key Events and Intellectual Shifts

During the Great Depression and the Second World War, mainstream economists faced significant intellectual challenges. The Great Depression and the social upheavals it precipitated led to a reevaluation of economic theories. This period is often referred to as the "Keynesian revolution," named after John Maynard Keynes, whose theories were seen as a radical departure from traditional economics. Joan Robinson's interest in Marxian economics was spurred by the need to find alternative explanations for economic phenomena that were resistant to mainstream theories.

Joan Robinson and Marxian Economics

Joan Robinson, influenced by her studies under Alfred Marshall, began to explore the works of Karl Marx in the 1940s. Her book, An Essay On Marxian Economics, was a seminal work that brought Marx's ideas to a broader audience, especially within the sphere of academic economics. Robinson emphasized the similarities between Marxist and Keynesian theories while rejecting the labor theory of value, a key component of Marx's work. This approach helped mainstream economists to consider Marx more seriously, albeit with reservations.

Contemporary Challenges and Criticisms

Despite some contributions, Marxist economists often face a resistant mainstream, which views them as outdated or politically oriented. A Quoran once summarized the mainstream view by stating, "they are fossils from the bad old days. There are a few departments that still hire such people but they’re very much outside the mainstream right now. Less because of their political beliefs much more because their methodology is generally regarded as old fashioned and useless." This sentiment suggests that the mainstream perception of Marxist economics is rooted in a belief that such theories are no longer relevant or useful in modern economic analysis.

Mathematical Models and Economic Methodology

Despite perceived neglect, many Marxist economists engage with mathematical models, econometrics, and statistical analysis. While it is true that there are dissenters within the Marxist camp who do not use these tools, this is also the case within mainstream economics, where certain groups eschew mathematical approaches. The Austrian School, for instance, refrains from mathematical models due to philosophical differences, but this does not diminish their relevance in economic discourse.

Philosophical Antipositivism

Both Marxist and Austrian economists share a commitment to antipositivism, which rejects the positivist approach of relying solely on empirical data and strict scientific methods. This philosophical stance is a common ground that underscores the intellectual complexity and diversity within economic theory.

Ultimately, the relationship between mainstream and Marxist economics is one of dynamic tension and continuous evolution. As societies and economic conditions change, so too do the frameworks through which we understand and analyze them. The dialogue between these two schools of thought is vital for the advancement of economic theory and practice.
