Economics and Responsibilities …

Teaching economics is of course a balance act – the need to make students familiar with what is available in the poison cabinet of mainstream economics, and at the same time avoiding even during the short available time that anybody gets tempted by the captivating simplicity of the technical formulas (or repelled by the seeming neutrality). – Yes, Milton Friedman had been right, quoting about myths:
