Editing Marginalism (section)

=== Marxist adaptations to marginalism ===
Some economists strongly influenced by the [[Marxian economics|Marxian]] tradition such as [[Oskar Lange]], [[Włodzimierz Brus]], and [[Michał Kalecki]] have attempted to integrate it with the insights of classical [[political economy]], marginalism, and [[neoclassical economics]]. They believed that Marx lacked a sophisticated theory of prices, and neoclassical economics lacked a theory of the social frameworks of economic activity. Some other Marxists have also argued that on one level there is no conflict between marginalism and Marxism as one could employ a marginalist theory of supply and demand within the context of a big picture understanding of the Marxist notion that capitalists exploit [[surplus labor]].<ref>Steedman, Ian; ''Socialism & Marginalism in Economics, 1870–1930'' (1995).</ref>
