Walrasia is a collection of interactive economics courses, made to be played on a phone. In every lesson you predict what will happen, you drag the curves, you answer questions, and when an answer is wrong you find out why.
I studied economics at university. Today I work at a school, and my job has nothing to do with economics. It is still the subject I love most, and over the years I never stopped reading about it.
I built this site first of all for myself. My bachelor's degree mostly taught me how little economics I really understood. Years later I enrolled in a master's degree in economics, while working, and I started Walrasia to review the basics and to study the new ideas before and during the courses. I finished the degree at 39.
The name comes from Léon Walras, a French economist who described the whole economy as one system of connected markets. One of the lessons on this site tells his story.
I hope the lessons are useful to you too.
