Lausanne School of Economics. The "Mathematical" school of thought surrounding the Leon Walrus and later that of Vilfredo Pareto (both French). The central feature was the development of General Equalibrium Theory. This was what I intuitively rebelled against in my first economics class in 1967, saying in class that if my uncle, who owned seven banks in Miami, used this methodology, he would be broke. The class laughed and I was failed. I was vindicated decades later by the Austrian School.
