Abstract

This paper analyses some important aspects that are considered in the capitalist
process of calculus used in the decisions of investment. The bases for this analysis are the
argumentation presented in the fifth chapter of the doctorate thesis of Si?lvia Possas (1993).
Some own reflections about these arguments and of distinguished Post-Keynesians are also
ser forth, for Possas neglected certain important points in the discussion she made in this
chapter that re-elaborates some reasonings of Keynes (1936) and of these Post-Keynesians.
