Given the following national-income model of implicit functions YCI0G0=0C(YT)=0TY=0 We know the endogenous variables are Y,C,T and the exogenous variables and parameters are I0,G0,,,, (a) According to implicit function theorem, if the Jacobian determinant is nonzero, we have the explict function exist. Show the Jacobian determinant is not zero. (b) Show matrix form of the implicit function theorem to find the comparative static analysis of the Y/G0,C/G0,T/G0 (c) Find Y/G0 by using the Cramer's rule Given the following national-income model of implicit functions YCI0G0=0C(YT)=0TY=0 We know the endogenous variables are Y,C,T and the exogenous variables and parameters are I0,G0,,,, (a) According to implicit function theorem, if the Jacobian determinant is nonzero, we have the explict function exist.
