Comentario en el SMP sobre la confusión de que la tasa de interés es el precio del dinero. También con algún insight de donde proviene este error en el sistema keynesiano.
The notion that the interest rate is the price of money is seriously misled. As I move forward with my lectures on the Keynesian system, this is something that I want to make clear to my students. Certainly, when evaluating the Keynesian model, we need to understand what the model says (and what it does not say), but unfortunately, textbooks do not always tackle controversial issues. This is an example of the perpetuation of errors and misconceptions by textbooks. To see this for yourself, simply open a random macroeconomics textbook and read what it has to say about the classical economists– then, open a book actually written by a classical economist and compare what the two have to say.
