Conditional validity of the equilibrium in Keynes' General Theor

Abstract

 It discusses that the equilibrium in Economics, as a method of analysis, has a conditional utility, when it is not necessary its association with ideal situations and with a constancy of structural parameters of the system. Keynes (1936) appears as an example of a good utilization of that method, for he doesn't link it with notions of social potmum or with a necessary system's structural stability.
