For all the questions below select the appropriate answer: a) A closed economy without a government sector is described by the following equations: Consumption: C = 100 + 0.5Y Investment: I = 50 The equilibrium level of real income (Y) for this economy is: O 300 O 150 O 200 O unknown because the information given is incomplete b) When an economy is at its equilibrium level of output, we know that: consumers' purchases of goods equals the total value of the goods produced by the economy. O planned aggregate expenditure is to equal the value of the aggregate output produced by the economy. O actual aggregate spending by the private sector equals the value of the output produced by the economy. O firms will not hold any inventories. c) Table 1.

In terms of this diagram. a tall in consumption at every level of income. and the corresponding increase in saving will: fj- leave investment unchanged but lower consumption and the equilibrium income. C- increase investment, shift the AE function up and increase equilibrium income. Q increase the slope of the consumption function and increase equilibrium income. fj- change the slope of the investment function but leave equilibrium income unchanged. 0) Investment expenditure is: {it expenditure by business on currently produced buildings, equipment and inventories. f) a component of autonomous aggregate expenditure. O more volatile relative to real income than consumption expenditures by households. {it all ofthe above
