34. T F Classsical macroeconomists denied that the level of spending in an economy could be too low to bring about the purchase of the entire full-employment output.
T
53. T F Keynes' solution to close a recessionary expenditure gap and achieve full- employment GDP was either or increase taxes or reduce government spending.
F
56. T F Overproduction was considered an impossibility by J.M. Keynes.
F
58. T F To avoid a recession or depression, Keynes recommended that government decrease spending or increase taxes.
F
60. T F The classical economists disproved the theory of Keynes by showing that the market economy does not automatically move toward full employment.
F
32. T F The classical economists dominated economic thinking prior to the 1930s. They concluded that, over time, the economy will automatically adjust to operate at full employment.
T
37. T F J. M. Keynes attacked Say's Law by noting that during an economic downturn not all income need be spent on goods and services. In fact, businesses will slash investment spending and a lot of saving will not be put into productive use.
T
36. T F The Great Depression of the 1930s called into question the optimistic economic conclusions of the classical economists.
T
43. T F Changes in aggregate expenditures (demand) will cause the equilibrium real GDP to change in the same direction by an amount greater than the initial change in aggregate expenditures. The reason for this greater change is the multiplier effect.
T
1. John Maynard Keynes created the aggregate expenditures model based primarily on what historical event? A. Bank panic of 1907 B. Great Depression of the 1930s C. Spectacular economic growth during World War II D. Economic expansion of the 1920s
B
23. A $1 increase in government spending on goods and services will have a greater impact on the equilibrium GDP than will a $1 decline in taxes because: A. government spending is more employment-intensive than is either consumption or investment spending. B. government spending increases the money supply and a tax reduction does not. C. a portion of a tax cut will be saved. D. taxes vary directly with income.
C
24. In a mixed closed economy: A. government purchases and saving are injections, while investment and taxes are leakages. B. taxes and government purchases are leakages, while investment and saving are injections. C. taxes and savings are leakages, while investment and government purchases are injections. D. taxes and investment are injections, while saving and government purchases are leakages.
C
25. Refer to the above diagram. The sizes of the multipliers associated with changes in investment and government spending in this economy are: A. 2.5 and 1.5 respectively. B. 3 and 2 respectively. C. both 2.5. D. 2 and 3 respectively.
C
8. In a private closed economy, when aggregate expenditures (AD) equal GDP (AS): A. consumption equals investment. B. consumption equals aggregate expenditures. C. planned investment equals saving. D. disposable income equals consumption minus saving.
C
47. T F If there is an increase in incomes in other nations that trade with the United States, American firms will sell less goods abroad. This decreases U.S. net exports and results in decreases in real GDP for the United States.
F
48. T F A depreciation in the exchange value of the U.S. dollar will decrease the purchasing power of foreign currency. As a result, U.S. net exports will decrease and real GDP will fall.
F
44. T F The equilibrium real GDP in a private open economy means real GDP is equal to consumption plus investment plus net exports.
T
40. T F Keynes developed the aggregate expenditures (demand) model during the 1930s when there was high unemployment and underutilized capital. Prices in such an economy were fixed or stuck because the oversupply of productive resources kept prices low. Thus, the aggregate expenditures model assumes constant prices.
T
41. T F In the aggregate expenditures model, the equilibrium real GDP occurs at that point where aggregate expenditures (demand) equal real GDP (aggregate supply). In graphical terms, the aggregate expenditures schedule crosses the 45-degree line.
T
46. T F An increase in net exports will increase the equilibrium real GDP with a multiplier effect. A decrease in net exports will do the opposite.
T
49. T F Household taxes decrease consumption and the aggregate expenditures (demand) schedule by the amount of the tax times the MPC.
T
50. T F Government purchases of goods and services add to the aggregate expenditures (demand) schedule and increase equilibrium real GDP. An increase in these purchases has a multiplier effect on equilibrium real GDP.
T
51. T F If the equilibrium real GDP is less than the real GDP consistent with full- employment real GDP, there exists an inflationary gap (inflationary expenditure gap).
T
52. T F The size of a recessionary gap (recessionary expenditure gap) equals the amount by which the aggregate expenditures schedule must shift upward to increase real GDP to its full-employment level.
T
55. T F An inflationary gap (inflationary expenditure gap) results from excess spending and will increase the price level, creating demand-pull inflation.
T
57. T F Keynes argued that prices and wages were inflexible in a downward direction due to the market power of big businesses and labor unions.
T
33. T F The classical economists believed that active government intervention is needed in the economy if the economy is to achieve full employment of resources.
F
38. T F In contrast to the more laissez-faire view of Keynes, the classical economists argued that government should play an active role in stabilizing the economy.
F
42. T F At below-equilibrium levels of GDP, aggregate expenditures (demand) is less than aggregate supply. Thus, there occurs unintended investment through increased business inventories.
F
45. T F The net exports schedule can be positive or negative. The schedule is positive when imports are greater than exports—a balance of trade deficit occurs. The schedule is negative when exports are greater than imports—a balance of trade surplus occurs.
F
54. T F The Great Recession of 2007-2009 was an example of an inflationary gap.
