Endogeneity of financial sector and economic growth: an empirical analyze of the Brasilian economy

The objective of this paper is to build a four sector model that make the financial sector endogenous and under the influence of families and government policies. As a result, the long run economic growth is influenced by monetary variables like the size of bank reserves, interest rates and inflationary tax. This model was empirically estimated through Auto-regressive Vector (VAR) and submitted to exogeneity tests. The results were that interest rate and inflationary tax are endogenously related to economic growth and affect only its variability. However, the bank reserve policy is exogenous to this variable and showed to have permanent effect on it, more specifically, in sum, the reserve bank policy set the amount of loan in the economy and it influences economic growth. Our estimation indicates that the rise of the bank reserve in 10 points might reduce the economic growth rate as much as 1.2%.
