In The Street Economist, Axel Kaiser offers basic lessons in economics that should be part of everyone's education. It is an effort to correct the mistake of " ivory tower economists" who conceive this science as an oracular discipline that can only be properly discussed by experts. Crucial concepts such as prices, capital, demand and supply, labor, inflation, value, and innovation, among others, are explained in simple and direct language in order to make them understandable to the general public.

The Street Economist has been a best-selling book in almost all countries where it has been published. In Chile, it sold more than 50.000 copies in a year, and it is still the most sold nonfiction book after a year of its publication. It is now being published in 5 different languages.
