Ignorance is Bliss: Why should we study Leontief?

What is at stake?

Let’s start with a story. A friend asked me what my favourite genre of fiction is. I replied: microeconomics. If you get the joke, you would be laughing. Otherwise, you would be wondering why I said that. Well, that’s the truth. Take any standard economics textbook, we find ourselves in the fictional worlds of ‘let’s assume there are two goods’ and ‘if we move from point A to B’. It is true and well understood that these assumptions and imaginations are meant to break down complex phenomena. However, this entry point of supply and demand curves with the endless possibilities of hypothetical scenarios is not the only way to study/introduce economics. In this regard, I put forth the relevance of studying Wassily Leontief’s work and argue that it adds pluralism to economics education at least in three aspects: 1) methodology (philosophical and mathematical approach), 2) the unit of analysis (micro to macro and in between), and 3) ideas at the margins (reading thinkers like Piero Sraffa and other classical political economists). Now we shall deal with these three themes individually.

Review of Macroeconomics by Alex M. Thomas

Macroeconomics: An Introduction by Alex M. Thomas, Cambridge University Press, 2021.

This recently published introductory Macroeconomics textbook written by Alex M. Thomas provides a refreshingly novel approach to teaching Macroeconomics to undergraduate students. As the author points out in the Preface, this textbook offers a “problem-setting approach rather than a problem-solving one, as is the case with most economics textbooks” (Page xvi, emphasis mine). The textbook has nine chapters, and the chapters have enough material to whet the appetite of a broad audience – Chapters 1,2,6 and 9 deal with the history and philosophy of Macroeconomics, Chapters 3-5 deal with the core economic theory of money and interest rates, output and employment levels and economic growth and Chapters 7 and 8 talk about the macroeconomic policy of achieving full employment and tackling inflation. In this review, I would focus on four issues – the commitment of the book towards enhancing pluralism in Macroeconomics, the importance given to studying macroeconomic theory, the idea of relating macroeconomic concepts to the context which is being studied and an explicit concern to make Macroeconomics accessible to an undergraduate audience residing in underdeveloped parts of the world.

Pluralism in economics – its critiques and their lessons

By Claudius Gräbner and Birte Strunk

In a recent paper we engaged with common critiques of the concept and the movement for more pluralism in economics. We found that while the majority of the critiques are either unfounded, easy to dismiss or address strawmen, others do highlight challenges the pluralist movement should address.

In 2017, we were spending a week at the Summer Academy for Pluralist Economics, when the German economist Johannes Becker published a blog article on Makronom entitled “The Movement for Pluralist Economics risks its success” (translated from German). He argues that the movement for pluralist economics faces a decision: it could continue to be a movement of fundamental opposition against the ‘economic mainstream’, or it could start striving for ‘real change’. Economics professors, at least in Germany, Becker argued, were highly perceptive and open-minded towards alternative perspectives in economics. If the movement would focus more on constructive engagement with economics faculties rather than on fundamental critique, then there would be a greater amount of pluralist seminars and lectures.

Being surrounded by around 100 fellow pluralists who dedicated a week of their summer to study different approaches to economics, the accusation of simply being a movement of unconstructive opposition seemed alienating to us. So we drafted a response, arguing that pluralist economics is about both critique and the construction of alternative practices. Based on this response, we wrote an article evaluating the critiques posed toward pluralist economics, drawing from philosophy of science, philosophy of economics, and philosophy of interdisciplinarity. When writing the paper, which has recently been published in the Journal of Economic Methodology, we indeed found many critiques of pluralism to be unconvincing, yet we also discovered that some critiques of pluralism are not easily dismissed. They should be taken seriously by pluralists because an honest engagement with these critiques rather than the neglect of their relevance could, we believe, make the movement for pluralism in economics more convincing and successful.
