In the aggregate expenditure model, equilibrium is the point where the aggregate supply and aggregate expenditure curve intersect. The classical aggregate expenditure model is: AE = C + I. Classical economics states that the factor payments made during the production process create enough income in the economy to create a demand for the ...

The Investment Multiplier. The model of Aggregate Expenditures that we are currently considering is often called a Keynesian Model because it was first formulated by British economist John Maynard Keynes in his General Theory of Employment, Interest, and Money, published in 1936—at the height of the great depression. One of the central premises of Keynesian economics is the idea of a multiplier.
