“Local differences in the prices of commodities whose natures are technologically identical are to be explained on the one hand by differences in the cost of preparing them for consumption (expenses of transport, cost of retailing etc.) and on the other hand by the physical and legal obstacles that restrict the mobility of commodities and human beings.”

Austrian and American political economist and philosopher

He is known for his work on classical liberalism and the place of consumers in a market economy. He wrote and lectured widely on the social value of classical liberalism, and on praxeology, the study most closely associated with his work.
