The omitted mathematics of Hans von Mangoldt

Discusses the economic thought of Hans von Mangoldt (1824‐1868). We discuss how this German classical author seems to anticipate later “neoclassical” ideas, such as Schumpeter’s theory of the entrepreneur, Marshall’s partial price analysis and the graphical representation of supply and demand. We discuss these graphical representations and conclude that Mangoldt does not take the role of time into account. Investigates why Mangoldt’s contemporaries did not pay much attention to these theoretical developments and describes how Mangoldt’s most interesting mathematical theories were omitted in the posthumous editions of his principal work.
