Where to Find the Numbers

Macroeconomics The course is divided in three parts: Short -run / Medium-run / Long-run Short – run (sticky price): 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 (flexible price): 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 (factor supplies change): 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
