The temporal single-system interpretation (TSSI) of Karl Marx's value theory emerged in the early 1980s in response to renewed allegations that his theory was "riven with internal inconsistencies" and that it must therefore be rejected or corrected. The inconsistency allegations had been a prominent feature of Marxian economics and the debate surrounding it since the 1970s. Andrew Kliman argues that charges of inconsistency serve to legitimate the suppression of Marx's critique of political economy and current-day research based upon it as well as the "correction" of Marx's inconsistencies.
