O b) Financial crisis results in a freezing of Interbank lending. c) Drought destroys half of a country's crops. ( d) Tax for energy use introduced to help reduce global emissions. Question 8 Keynes rebelled against the neoclassical assumption. What does that mean? O .) Prices are not flexible. b) Inflation must be Ignored In the short run. O c) Prices are fully flexible. O d) None of the above. Question 9 In the Keynesian view, the price level is (A) In the neoclassical view, the price level Is (B) O .) (A) endogenous, (B) exogenous. O b) (A) exogenous, (B) endogenous. O c) (A) relevant, (B) irrelevant. O d) (A) irrelevant, (B) relevant. Question 10 What is a problem the Central Bank has to face when setting interest rates? a) Setting interest rates is unproblematic. O b) It has to fix the exchange rate, too. O c) It must withdraw former loans. ( d) It must supply all demanded liquidity.Question 1 The negative relationship between the gap between actual GDP and its trend value and the difference between actual unemployment rate and its equilibrium value is called: O a) The Aggregate Supply Curve ( b) The Battle of the Mark-ups O c) The Phillips Curve O d) Okun's Law Question 2 The reason for the long-run stability of the labour share is: ( a) Price mark-ups over labour costs have remained relatively constant. b) Real wages increase with technical progress resulting in a reduction in labour demand so the product of real wages and employment remains constant. O c) The battle of the mark-up ensures that the change in nominal wages equals inflation. O d) Technical progress has continuously generated higher incomes Question 3 Dividing nominal wages (W) by labour productivity (Y/L) yields: a) Real unit labour costs ( b) Nominal unit labour costs O c) Total factor productivity ( d) Labour share of total income Question 4 Inflation AS B Output At point A, inflation is equal to the underlying rate of inflation and output is at the level of output consistent with the equilibrium unemployment rate. If the economy were at point B, you would expect... a) ..the underlying rate of inflation to accelerate because the actual inflation rate exceeds the underlying rate of inflation. b) ..prices will decline because there is an excess supply of goods (neoclassical assumption). O c) ..output to decline because there is an excess supply of goods (Keynesian assumption). ( d) ..consumer spending to decline because goods are more expensive. Question 5 The critical macroeconomic policy implication of a vertical long-run Phillips Curve is that. a) ..inflation is everywhere and always a monetary phenomenon. ( b) ..big inflations will be stopped by big recession. ( c) ..money illusion is the source of the unemployment in the long-run. d) ..demand policies cannot move the actual unemployment rate permanently away from its equilibrium level. Question 6 "It is better for an economy to have a 5% rate of inflation over a 5% rate of unemployment." Without getting into a debate on the relative costs of unemployment and inflation yet, why do we know this statement is not helpful for policy makers, even if the prime minister says this explicitly? ( a) The economy is dichotomized in the short-run because of the Taylor rule. b) Wage-negotiations are subject to money illusion so that real wages would fall to an unsustainable level. c) Even if we could reduce unemployment to 0% today at a cost of an increase in inflation of 5%, there is no guarantee that underlying inflation in the economy would remain unchanged
