So this question asks us to explain why the aggregate expenditure line is upward sloping, but the aggregate demand curve is now or sloping.
00:09
So first thing we need to know that when we try to draw the growth for aggregate expenditure, so this is on the x -axis, it is a real gdp, and on the y -axis, it is a real aggregate expenditure.
00:23
So basically, we have the 45 -degree line here, and basically the aggregate expenditure, curve is upward sloping because there is a positive relationship between aggregate expenditure and real gdp.
00:38
So in some case, we can say that the higher the real gdp, the higher the average expenditure.
00:44
So there is a positive relationship between it.
00:47
But when we try to draw the graph for aggregate demand curve, so in general we have on the one axis it is the price...
