DECISIONS OF THE POWERFUL CAPITALISTS AND UNCERTAINTY: A RATIONAL EXPECTATION APPROACH

This paper is about the relation between giant companies and uncertainty of the monetary rule. the uncertainty comes from the decisions of the giant capitalists which are holding huge amount of capital and their future expectation. their expectations and decisions are important for the future because their revenues are almost a country’s gdp (gross domestic product). therefore, their revenues are big enough to affect economies. the main difference of the paper is the adding the decisions of the giant companies in a basic rational expectation model. also, subject of the paper depends on marxian monopolistic competition and surplus value theories. as a result, monetary authority is affecting the output, but unknown result so monetary rule is not efficient for stabilizing economy. new classical economy proposes the similar result. however, this paper explains why monetary policy is ineffective for stabilizing economy considering decisions of the giant capitalist.
