5. Results
The estimated parameters for the model defined by [1], [3] and [5] equations, using variables
in table 2,3,4,5,and 6 are presented in table 7. Only exogenous variables statistically different
from zero, at a significant level of 0.05, have been finally included. Results show that
correlations between equations are significant at 5% level. It means that errors for all
equations are correlated. Therefore, we can conclude that the equations are not independent
and that the simultaneous estimation of both equations in the model is the appropriate
approach to obtain consistent parameter estimates.
