4. Consider the following structural macroeconomic model:
ㆍProduction function: Y =- F(N, K)； Fข ＞ O, Fx ＞ O.
ㆍLabor demand: 뜻 = Fr(N, K)； FNN ＜ O, FKk ＜ O.
ㆍConsumption: C =C(Y - T,)； 1 ＞ Cy ＞ O, C, ＜ O. 
ㆍInvestment: I = I(r y)； Iy ＞ O, I, ＜ O. 
ㆍGoods market equilibrium: Y = C + I + G. 
ㆍMoney market equilibrium: "6316b60e3c681.jpg=m(r,y)；mT ＜ 0,my ＞ 0. The terms Y(nominal GDP), y(real GDP), N(employment level), P(price level), C(consumption), r(interest rate), I(investment) are endogenous variables while K(capital stock), W(nominal wage), T(tax), G(government purchase), M(money supply) are exogenous variables.

(C) (7 points) What are the effects of an increase in government spending on y, r and P? What are the effects of an increase in money supply on y, r and P? (7%)
