YouTube has the podcast #125 Sam Levey: Monopoly, Monopsony, And What To Do About Them.

Patricia and Christian talk to economics scholar, teacher and writer Sam Levey about real existing economic conditions (containing monopoly, monopsony, and oligopolistic price-setting power), the inadequate models used by economists to interpret these conditions, and a better way forward.

Interesting podcast. I think it is better if you already have some understanding of the topic to form your own judgment on some of what is being said.
