Once again the equilibrium interest rate clears the market for loanable funds: 8=1 500 = 1,000 -50r Solving this equation for r, we find: r = 10%. 7. To determine the effect on investment of an equal increase in both taxes and govern-ment spending, consider the national income accounts identity for national saving: National Saving [Private Saving] + [Public Saving] [Y -T -C(Y - TI] + [T - 0]. We know that Y is fixed by the factors of production. We also know that the change in consumption equals the marginal propensity to consume (MPC) times the change in disposable income. This tells us that ~ational Saving [-!1.T -(MPC x ( !1.T))] + [!1.T -!1.G] :::: !1.T + (MPC x !1.T)] + 0 = (MPC - 1) !1.T....
