Becoming an Economist is the introductory course on economics for undergraduates at Kingston University. This is the first of 11 lectures in the subject; I’ll post the others as I write them over the next few months. This lecture discusses why economists disagree with each other, and draws analogies with astronomy at the time when Galileo discovered craters on the Moon, and moons orbiting Jupiter and Saturn.
This is the Powerpoint file for the lecture, which includes links to the Youtube videos used in this lecture:
