1925-1987 Professor of Economics at Saarland University. One of the most methodologically original German economists of the 20th century - influential within the discipline, largely unknown in public discourse.
Stützel’s central contribution is the [[Saldenmechanik-en]] (economic balance mechanics, 1958): a formal framework that strictly separates accounting identities from behavioral hypotheses and distinguishes overall statements (what applies to all actors together) from partial statements (what applies to a single actor). In this way, he makes the composition fallacy in economics visible and open to attack: What is true for the partial can be false for the whole.
In 1952, Stützel published the posthumous writings of Lautenbach en and named its core result the entrepreneurial profit equation - an example of his practice of using precise terms where others argued vaguely. In his famous “Oberseminar” he introduced generations of students to balance-mechanical thinking; [[Flassbeck-en]] is the best-known representative of this tradition.
Stützel was liberal and defended the market - but never understood this as a license to ignore macroeconomic logic. He criticized both demand-policy activism without a balance-mechanical foundation and supply-theoretical orthodoxy, which inadmissibly transferred microeconomic categories to the economy as a whole.
His sentence about the spectator at the procession - “An individual can stand up to see better. All cannot ” - is the most succinct German-language formulation of [[Aggregationsparadoxon-en]].
