2013-9-17  The Aggregate Supply curve is represented by the 45° line. Throughout this line the planned expenditure is equal to the planned output. That is AS = Y = Expenditure.The implication of 45° line is that in case of any disequilibrium, AS will be adjusted in a way to equate AD in order to restore equilibrium back. That is in other words, in case of any inequality between AD and AS, equilibrium ...

2021-11-12  Many of you will have spent quite a lot of time looking at '45 degree' diagrams, or 'Keynesian cross' diagrams. Until a few years ago, they were the main way in that the expenditure and income aggregates where analysed. Nowadays, aggregate demand and supply diagrams are preferred, although many teachers still like to explain the situation using the 'good old' 45-degree diagram.

The second conceptual line on the Keynesian cross diagram is the 45-degree line, which starts at the origin and reaches up and to the right. A line that stretches up at a 45-degree angle represents the set of points (1, 1), (2, 2), (3, 3) and so on, where the measurement on the vertical axis is equal to the measurement on the horizontal axis.

2021-4-23  Why is aggregate supply 45 degrees? The Aggregate Supply curve is represented by the 45° line. Throughout this line the planned expenditure is equal to the planned output. That is AS = Y = Expenditure. The implication of 45° line is that in case of any disequilibrium, AS will be adjusted in a way to equate AD in order to restore equilibrium back.
