Refer to the above figure. If the marginal propensity to consume increases to 0.8, equilibrium output Question 8 options: increases to $250 million remains at $200 million increases to $400 milion cannot be determined as we do not know the progressive tax rate, t Refer to the above figure. If government expenditure decreases by $20, equilibrium output: decreases to $150 does not affect the marginal propensity to consume (b) does not affect the progressive tax rate (t) all of the above Refer to the above figure. If investment expenditure increases by $10, equilibrium output will increase to Question 5 options: $210 million $90 million $225 million Refer to the above figure. The equation for the demand line is: Question 3 options: Demand = $80 +0.4Y Demand = $80 +0.6Y Demand =$120 +0.6Y Demand = $120 +0.4Y [Aggregate Income/ Aggregate Output].
