### Question about NA in model result and endogenous variable

Posted: Thu Feb 11, 2016 5:45 pm
I try to solve for this model
I use the instrument variable to solve for each equation.
m_s, p and gov are all exogenous variables while others are endogenous variables.
Now the problem is that there are some NA in results and r_l is an exogenous variable rather than endogenous variable.
Also, p suppose to be an exogenous variable but it does not show in the model.

Thank you so much and I really appreciate your help.

I don't really understand what you're asking/saying.

The model in that workfile has 5 equations.

• gdp = cons + inv + gov
• m = m_s
• m_p = -25977.6 + 0.0233*gdp- 9155.3*r_l + (ar term)
• cons = 1140319.6 + 0.310567*gdp + (ar term)
• inv = -410824.3 - 70748.35*r_l + 6.61*D(gdp(-1)) + (ar term)

No where is "p" mentioned. Clearly gov, m_s and r_l are exogenous variables, and everything else is endogenous.
