El Mapa no es el Territorio: Un Ensayo sobre el estado de la Economía

El Dr. Alejandro Villagómez, Profesor-investigador del CIDE, autor del Blog "Tintero Económico" e invitado permanente de "Economía desde Nayarit" ha llamado nuestra atención hacia un muy interesante ensayo de John Kay titulado The Map is Not the Territory: An Essay on the State of Economics.

Aquí algunos fragmentos:

"A review of economics education two decades ago concluded that students should be taught ‘to think like economists’. But ‘thinking like an economist’ has come to be interpreted as the application of deductive reasoning based on a particular set of axioms. Another Chicago Nobel Prize winner, Gary Becker, offered the following definition: ‘the combined assumptions of maximising behaviour, market equilibrium, and stable preferences, used relentlessly and consistently form the heart of the economic approach’.[13] Becker’s Nobel citation rewards him for ‘having extended the domain of microeconomic analysis to a wide range of economic behavior.’ But such extension is not an end in itself: its value can lie only in new insights into that behaviour."


"Economic models are no more, or less, than potentially illuminating abstractions. Another philosopher, Alfred Korzybski, puts the issue more briefly: ‘the map is not the territory’.[15] Economics is not a technique in search of problems but a set of problems in need of solution. Such problems are varied and the solutions will inevitably be eclectic."


"This pragmatic thinking, employing many tools, is a better means of understanding economic phenomena than ‘the combined assumptions of maximising behaviour, market equilibrium, and stable preferences, used relentlessly and consistently’ – and to the exclusion of any other ‘ad hoc’ approach. More eclectic analysis would require not just deductive logic but also an understanding of processes of belief formation, anthropology, psychology and organisational behaviour, and meticulous observation of what people, businesses, and governments actually do. You could learn nothing about how these things influence prices if you started with the proposition that deviations from a specific theory of price determination are ‘too small to matter’ because all that is knowable is already known and therefore ‘in the price’. And that is why today’s students do, in fact, learn nothing about these things, except perhaps from extra-curricular reading."

I'm amazed, I have to admit. Rarely do I encounter a blog that's equally educative and interesting, and let me tell you,
you've hit the nail on the head. The problem is an issue that not enough people are speaking intelligently about. Now i'm very
happy that I found this during my hunt for something regarding this.
