6) Suppose an economy is closed and given by the following equations: Y = C +I+ G C = cO+c1 (Y-T) Gand I are both constant Assume that the tax function is a linear relation. The relation between tax and output is characterized by two parameters, t0 and t1: 1 The parameter t1 gives the effect an additional dollar of output has on the total tax. t1 is positive: An increase in output leads to an increase in the total tax. -The parameter tO is what the tax in the economy would be if output in the current year were equal to zero. a). Solve for equilibrium output.
