Contrary to the views of new Keynesian economists working in the neoclassical tradition, post-Keynesians do not accept that the theoretical basis of the market's failure to provide full employment is rigid or sticky prices or wages.
I modsætning til nykeynesianerne mener post-keynesianerne ikke, at det teoretiske grundlag for markedets manglende evne til at skabe fuld beskæftigelse er stive eller træge priser og lønninger.
