Consider a simple Keynesian model without government spending or taxation. Suppose autonomous consumption is 500 and autonomous investment is 300 and the equilibrium level of output is 2400. Then the marginal propensity to consume is: Group of answer choices2/33/53Uncertain, not enough information.

In the Keynesian income-expenditure model, equilibrium income is necessarily equal to a multiple ofGroup of answer choicesthe autonomous component of consumption, regardless of whether the economy is closed or openthe exogenous component of planned aggregate expenditurethe marginal propensity to consume minus the sum of the marginal tax rate and marginal propensity to importnone of the other alternatives are correct.

Consider a simple Keynesian model with taxation. Suppose the marginal tax rate is t = 0.4 and the marginal propensity to consume is c = 0.66. Then an exogenous increase in investment demand of 100 units will:             Group of answer choicesIncrease equilibrium output by approximately 150 unitsIncrease equilibrium output by approximately 167 unitsIncrease equilibrium output by approximately 267 unitsIncrease equilibrium output by approximately 750 units

Assume that the level of autonomous consumption in an economy equals 400, the level of planned investment = 400.Calculate the marginal propensity to consume, if the level of income equals 2,000?Provide answer to one decimal point.

Assume the economy is closed and there is no government. The aggregate demand components are described below:C = 100 + 0.6Y (1)I = 200 (2)Now there is a boost in investment, and total investment is not 300.  What is the marginal propensity to consume?

Consider the following economy:(1) C = 1000 + 0.3 (Y - T)(2) I = 700(3) G = 500(4) T = 400What is the marginal propensity to consume?
