Prabhat Patnaik - Finance and Growth Under Capitalism
Once we reject Say’s Law and recognize that capitalism is prone to deficiency in aggregate demand, we have to accept that sustained growth in this system requires exogenous stimuli. By exogenous stimuli I mean a set of factors which raise aggregate demand but are not themselves dependent upon the fact that growth has been occurring in the system; that is, they operate irrespective of whether or not growth has been occurring in the system. Moreover, they raise aggregate demand by a magnitude that increases with the size of the economy, for instance with the size of the capital stock. They are in other words different from “erratic shocks” on the one hand, and “endogenous stimuli”, such as the multiplier‐accelerator mechanism, on the other: the latter can perpetuate or accelerate growth only if it has been occurring anyway.Read rest here.
