Editing Marginalism (section)

=== Markets ===
By confining themselves to limiting cases in which sellers or buyers are both "price takers"&nbsp;– so that demand functions ignore supply functions or ''vice versa''&nbsp;– Marshallian marginalists and neoclassical economists produced tractable models of [[Perfect competition|"pure" or "perfect" competition]] and of various forms of [[Imperfect competition|"imperfect" competition]], which models are usually captured by relatively simple graphs.  Other marginalists have sought to present what they thought of as more realistic explanations,<ref>Mund, Vernon Arthur; ''Monopoly: A History and Theory'' (1933).</ref><ref>[[Mises, Ludwig Heinrich Edler von]]; [http://library.mises.org/books/Ludwig%20von%20Mises/Nationalokonomie%20Theorie%20des%20Handelns%20und%20Wirtschaftens.pdf ''Nationalökonomie: Theorie des Handelns und Wirtschaftens''] (1940). (See also his [https://mises.org/books/humanaction.pdf ''Human Action''.])</ref> but this work has been relatively uninfluential on the mainstream of economic thought.
