The data, is used related to the period 1959-2000. To analyze the above-mentioned effect we employed a model of nine simultaneous equations. The method used to estimate the model is 2sls. After the estimation, the model is simulated by Newton method in order to determine the effects of unification on the endogenous variables the model.
