Generalized Method of Movement (GMM), Keynesian's Monetary Stagnation, Utility of Money

The notion of Liquidity Preference has become generally used in the literature on Keynesian monetary economics. Highly liquid with If the speculative or the precautionary motive leads to people hold liquid in high level, It induces persistent or chronic stagnation. If marginal utility of Money is positive, it will be a measure for the monetary stagnation. In this paper, the stagnation of Iran’s economy is examined by using Endogenous Growth Model and dynamic optimization approach with relative risk aversion assumption. In the first step, we estimate real interest rate and elasticity of the consumption and elasticity of the money as variables that have main roles in the final model. In the second step, coefficients of the money and consumption in the utility function are estimated during 1975- 2013 with using Generalized Method of Movement (GMM). The results find the evidence that confirms the Keynesian monetary stagnation. However, change in the definition of money from Fiat Money and Credit to Electronic Money influence on the result.
