Depending on the level of increasing coefficient on macro-economic variables, especially GDP, monetary & financial policies affects differently. To determine the efficacy of these policies, classic economists suggest using the relationship between different markets being analyzed based on commodity, money and labor markets. In this paper, we tried to analyze and to compare the effect of monetary and financial policies within the framework of commodity, money and labor markets by a collection of simultaneous equations. Logarithmic model was picked and instead of using increasing coefficient analysis, the concept of production elasticity on financial and monetary policy making variables was used. To estimate the equations, 3SLS was used. The research results showed that in the period of 1986-2011, there was a significant relationship between GDP sensitivity on practicing financial and monetary policies in Iran. Production sensitivity on financial policies was higher than production sensitivity on monetary policies, justifying Keynes approach on significant impact of financial policies on economy
