1. Let the equilibrium condition for national income be S(Y) + T(Y) = }{Y)+ Ge where S, Y, T, I, and G stand for saving, national income, taxes, investment, and gov- ernment expenditure, respectively. All derivatives are continuous. (a) Interpret the economic meanings of the derivatives S', T', and !'. (b) Check whether the conditions of the implicit-function theorem are satisfied. If so, write the equilibrium identity. (C) Find (dY*/dGo) and discuss its economic implications. (S', T', I' > 0; S'+ I' > l')
