In the basic Keynesian model, all statements below except for one are true. Which is the incorrect statement? Group of answer choicesPlanned aggregate expenditure is always equal to output in equilibrium. Planned government spending always equals actual government spending.Planned net exports always equal actual net exports.Planned investment always equals actual investment.Planned consumption always equals actual consumption.

In the simple two-sector Keynesian income-expenditure model with no government or external sector, assuming actual and planned saving are always equal, when aggregate output is less than aggregate planned expenditureGroup of answer choicesany unplanned change in inventories will be negativeactual investment is greater than planned investmentplanned saving is greater than planned investmentactual saving is equal to planned investment

In the Keynesian income-expenditure model, equilibrium income is necessarily equal to a multiple ofGroup of answer choicesthe exogenous component of planned aggregate expenditure which is partly dependent on the autonomous component of taxation when government is includedthe autonomous component of consumption, regardless of whether the economy is closed or openthe sum of investment, government expenditure and net exportsnone of the other alternatives are correct.

In the simple Keynesian model, which of the following statements is false? Group of answer choices An increase in the marginal propensity to save will reduce the level of income in the economy. The reduction in output from an increase in taxation is larger the smaller is the marginal propensity to consume. An increase in lump sum taxation accompanied by an increase in government spending of the same size will increase output. The equilibrium level of output does not depend upon the size of the money multiplier.

Adding an external sector to the Keynesian income-expenditure model implies that for equilibrium, in terms of leakages and injectionsGroup of answer choicesplanned saving must equal planned investmentplanned saving must equal planned investment, government expenditure must equal total taxation and exports must equal imports it is not necessary for planned saving and planned investment to be equal but exports must be equal to imports it is not necessary for planned saving and planned investment to be equal but they are unequal then either the budget or the trade balance or both should not be equal to zero.

Consider the Keynesian income-expenditure model with a government sector but no foreign sector. Assume that taxation is partly endogenous and dependent on the level of income. Suppose that the government increases its expenditure by $200 million and also increases the exogenous component of taxation by $200 million. Taking the budget balance as being equal to total taxes less government expenditure, which of the following statements is correct?Group of answer choicesThe equilibrium level of income will increase by less $200 million and the budget balance would improveThe equilibrium level of income will decrease but the budget balance would actually improveThe equilibrium level of income will increase by more than $200 million and the budget balance will be unchangedThe equilibrium level of income will increase by $200 million and the budget balance will be unchanged.
