Targets of a company and limitations of its growth - post-keynesian alternative to the economics of the main stream

There are many interesting issues within Post-Keynesian stream that are worth noticing and reviewing even by those economists who tend to decline notions raised by Keynes. Among others it is the theory of the firm, which deserves attention. If we adopt the notion of uncertainty about our future we are forced to tackle the economic reality in quite a different way. It is crucial for the economic system to sustain competitiveness, however, there are natural drifts for the firms to get larger and thus stronger in their everyday life. Discussions over these and other issues carried out by Post-Keynesians should not miss attention of general economic public since, as I view it, they hit the point of current world in a more adequate way than the orthodox theory does.
