The Banach-Tarski Paradox

• The Hahn-Banach theorem is related to how mainstream economics model perfect competition. The video above is mind-bending math.
• The Mountain Goat blog.
• A profile of some economists at Berkeley, some of who I have read when they collaborated with Thomas Piketty or A. Dube. I have read deLong, as well, of course.
• If you cannot name 'capitalism', 'neoliberalism', or 'neoclassical economics', it is difficult to criticize them. Here is a popular account about right-wingers crying about researchers daring to use such terms.
• I conclude with a recent talk, below, by Yanis Varoufakis on the need for pluralism in economics. He argues, at least (I still have more to watch):
• Economic theory can be performative, counter-performative, or reflexive (without using those terms).
• Time, money, debt, and interest rates do not appear in the models in the textbook.
• Markets can exist without a society being capitalist.
• Once you have learned all these models that have nothing to say about capitalism, you might possibly say something intelligent.
