Abstract:

This paper is about the relationship between giant companies and the uncertainty of the monetary rule. The uncertainty comes from the decisions of the giant capitalists which are holding a 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, the subject of the paper depends on Marxian monopolistic competition and surplus value theories. As a result, the monetary authority is affecting the output, but the unknown result so the monetary rule is not efficient for stabilizing the economy. New Classical Economy proposes a similar result. However, this paper explains why monetary policy is ineffective for stabilizing economy considering decisions of the giant capitalist.
