Termination of the history of economics courses contributing to the Global Financial Crisis (GFC)

Helge Nome : The key to controlling humans does not lie in building fences around them, but to steer their minds away from unwanted questions.

http://wileyeconomicsfocus.files.wordpress.com/2011/01/brainwashing1.jpgThe elimination of courses in the history of economics has contributed to the Global Financial Crisis (GFC) by eroding institutional memory that allowed the dismantling of structures designed to prevent a re-occurrence of the Great Depression.  With little space in the curriculum for reflection on the past, graduate economists feed on a diet of neoclassical mathematics produces an extreme form of bounded rationality where history is both irrelevant and unknown, which makes for a very powerful ideology by steering minds away from unwanted questions.

GDP as a proxy for well being misses the mark

leave a comment »

The report prepared for the President of France, Nicolas Sarkozy, by two Nobel prize-winning economists, Joseph Stiglitz and Amartya Sen, has proposed ways of improving our measurement of economic performance and social progress (Gittens 2009).  GDP measures the production of an economy.  There are at least three problems with GDP as a proxy for well-being.  First, this proxy may hold for countries outside the OECD membership, where the basics such as shelter, food, access to medical services, and clean water and sanitations are lacking.  Second, what is measured becomes a policy target, in this case a misguided target in OECD countries.  Third, GDP becoming a target circumvents the important discussion of what are suitable measures for well-being.  Equating the level of GDP to the level of well-being reduces the study of economics to an optimisation problem, allowing neoclassical economics the pretence of being scientific.  My post ‘The G8 protests and the logically inconsistent foundations of neoclassical economics’ further discusses this scientific pretence.

Comparing the role of government in self-control problems from behavioural and neoclassical economic perspectives

leave a comment »

In my previous post, titled ‘The G8 protests and the logically inconsistent foundations of neoclassical economics’ , I discussed how neoclassical economics is theoretically and philosophical flawed and how it has become entrenched in our political systems via university economics departments indoctrinating undergraduates with the neoclassical ideology. The current article discusses how the indoctrination produces a world view that causes confusion over the role of government and the concept of freedom of choice. Additionally, the current article provides an economic perspective on  ‘Weighing the blame for illness: biology versus personal responsibility‘ by Dena T. Smith. Read the rest of this entry »

The G8 protests and the logically inconsistent foundations of neoclassical economics

leave a comment »

Neoclassical economics is deductive, using a mathematical axiom-proof-theory format.   Arnsperger and Varoufakis (2006) list the three basic axioms of neoclassical as methodological instrumentalism, methodological individualism and methodological equilibration.   In such an approach the basic axioms have to be correct otherwise the whole framework becomes unsound.   In contrast to the deductive approach, the scientific approach is inductive, forming theories from observation and using prediction to falsify the theories (Neuman 2003, p. 51).   Neoclassical economists have become adept at avoiding empirical falsification by creating ad-hoc explanations as to why their theories fail to work when confronted with empirical evidence, for example the Efficient Market Hypothesis predicting dividend volatility in excess of price volatility but the converse is observed (Shiller 1981).   Falsification avoidance is the sign of a degenerative research program (Lakatos 1976).   So, rather than use empirical falsification, a more suitable approach to disprove deductive frameworks is to use a logical proof showing their axioms lead to an absurdity.   The Sonnenschein–Mantel–Debreu Theorem (Debreu 1959) proves the basic axioms of neoclassical economics are logical inconsistent.   The Sonnenschein–Mantel–Debreu Theorem (Debreu 1959) shows that starting with the first two axioms leads to a shapeless excess demand curve.   The shapeless excess demand curve means that there are multiple equilibria and equilibrium are unstable making the third axiom untenable.   To fix this problem, it is assumed that all goods have constant Engel curves.   A good would have a constant Engel curve if somebody spends the same proportion of their income on the good as their income grew (Keen 2001).   This is an unlikely scenario as when income grows then people consume more luxury goods and basic goods become a smaller fraction of their income.   Can you think of a good with a constant Engel curve?   Colander (2000, p. 3) equates neoclassical economics “to the celestial mechanics of a nonexistent universe” for using theory outside its domain assumption (Musgrave 1981).   That is neoclassical economics as a pursuit in pure mathematics for intellectual exercise is fine but claiming applicability to the real world is misleading.
