AM02: Supply & Demand

Summary:
From Asad Zaman 2nd Lecture (90min) on Advanced Microeconomics at PIDE, (14 Sep 2017). While planning to teach a heterodox micro course, I was faced with the dilemma of choosing a suitable textbook. Interestingly, there are many options available, but I was not happy with most of them. Some were too mathematical for my taste, some made too many concessions to conventional micro while being critical of it, and some were simply not suitable for use as texts. Eventually, I decided to use Rod Hill and Tony Myatt’s: The economics anti-textbook: a critical thinker’s guide to microeconomics. Zed Books Ltd., 2010. I am very pleased with this choice. It provides contact with conventional micro that we need, together with a critique that is easy to understand, and can be used as a basis for

Lars Pålsson Syll writes The non-existence of economic laws

I started the course (first lecture was preliminary introduction to methodology and approach) by covering Chapter 3: How Markets Work (In an imaginary world) of the H&M anti-textbook. This chapter attacks the central Supply and Demand model which is at the heart of mainstream micro in a beautiful and elegant way. I am impressed! I have myself written what I thought (and still think) is a very good critique (see The Conflict between General Equilibrium and the Marshallian Cross). I have also seen other critiques (like Sraffa). But H&M pointed out an angle that I had not considered before. They survey conventional textbooks to pick out the main message being conveyed in the S&D model and its policy implications. Then they show that the S&D model is heavily dependent upon the assumptions of perfect competition, which require small price-taking firms, full information and zero transaction costs. All conclusions of S&D and policy implications fail when firms have market power, and the reverse policy ocnclusions can be easily derived.   read more
