Economics in One Lesson is an introduction to economics written by Henry Hazlitt and first published in 1946. It is based on Frédéric Bastiat's essay Ce qu'on voit et ce qu'on ne voit pas.

The Austrian School is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result primarily from the motivations and actions of individuals and their self interest. Austrian school theorists hold that economic theory should be exclusively derived from basic principles of human action.
