Question 5 [5 points] 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 300 150 200 O unknown because the information given is incomplete b) When an economy is at its equilibrium level of output, we know that: O 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. Table 1.

In terms of this diagram. a tall in consumption at every level of income. and the corresponding increase in saving will: -'_'- leave investment unchanged but lower consumption and the equilibrium income. 0 increase investment, shift the AE function up and increase equilibrium income. C- increase the slope of the consumption function and increase equilibrium income. C- change the slope of the investment function but leave equilibrium income unchanged. 9) Investment expenditure is: G expenditure by business on currently produced buildings. equipment and inventories. f) a component of autonomous aggregate expenditure. f) more volatile relative to real income than consumption expenditures by households. O all ofthe above
