The State of Macro…a la Krugman Keynes (1936): Y = C + I + G –Economics of effective demand The “Golden Age” (1946 ~ 1973): Fiscal dominance Monetarist challenge: G crowded out/M-matters-most –Friedman: Avoid monetary mischief “Freshwater” dominance: Rat-X/Efficient Markets –Lucas: confusion  recession –Prescott: supply shocks  intertemporal substitution  recession “Saltwater” acquiescence: Rat-X with frictions –New Keynesian models/Monetarist policies Housing bubble: end of Great Moderation –Behavioral finance/return of Keynes 5

17 Where to Find the Numbers

18 Macroeconomics The course is divided in three parts: Short -run / Medium-run / Long-run Short - run: IS / LM  AD IS: Y = C + I + G C = c 0 + c 1 Y D = c 0 + c 1 (Y - T) I = I 0 + b 1 Y - b 2 i  Y = {spending multiplier} x {autonomous spending} LM: (M/P) d = (M/P) s (M/P) d = L(Y,i) M s = [1/(c + r(1-c))]H = {money multiplier} x {monetary base} Medium - run: AD/AS IS/LM  AD PS/WS  AS PS: P = (1+ μ)(W/A) WS: W= P e A e f(u,z) In medium - run, P e = P  (W/P) WS = (W/P) PS = A / (1+ μ)  Natural/Structural/Equilibrium Rate of Unemployment (u n )  “Full - employment” rate of output (Y FE )  The Green Shaft  SRAS and MRAS When AD or AS shift: MR equilibrium  SR equilibrium  P  new MR equilibrium Long - run: Growth Steady state: s(Y/AN) = (δ + g N + g A )(K/AN) For simple Cobb-Douglas function: Y = K α (AN) 1-α  Y/AN = {s/((δ + g N + g A )} α/(1-α) Golden - rule saving rate = α Productivity and equilibrium rate of unemployment: A e = A only in long - run  “Natural rate” decreases with unexpected increase in A
