Marginalism and Scope in the Early Methodenstreit

Recent interpretations of the early Methodenstreit (1871 – 1883) between Gustav Schmoller and Carl Menger no longer identify a substantial point of controversy. I reconstruct the debate to show that the pivotal topic was the scope of economics. Menger claims that his Principles of Economics more or less capture the full scope of the discipline, which Schmoller denies. I also discuss recent Menger scholarship, which follows Friedrich Hayek in situating Menger at the edges or even outside the marginalist mainstream. I argue that this interpretation wrongly denies Menger his pioneer status as, possibly the first, marginalist.
