Assume that the marginal propensity to consume is 0.75 and that taxes are exogenous. Imagine that government expenditure increases by $10m. Begin by assuming that the interest rate and prices stay fixed. 1. What is the value of the aggregate expenditure multiplier (k)? 2. How would the change be represented in an AD-AS diagram? 3. How would the change differ if the interest rate could change (assuming prices remain fixed)? 4. How would the change differ if the price level could also change?

Suppose that due ot a fiscal stimulus, there is an increase in disposable incomes of $100 billion in the first round. Then, $33 billion was spent in consumption from this initial change of the disposable incomes. Following the same marginal propensity to consume, how much is the change in consumption spending in the next round from the $33 billion?

Elaborate on the difference between a binding and non-binding borrowing constraints and thetwo consumption functions that result.b. From the Intertemporal Choice Model, many theories (non-Keynesian theories ofConsumption) came into being. Using graphical and mathematical expressions, compareand contrast the following theories on consumption behaviours:i. Franco Modigliani: Life-Cycle Hypothesisii.
