Which combination represents the IS curve?
The IS curve represents the locus where total spending (consumer spending + planned private investment + government purchases + net exports) equals total output (real income, Y, or GDP)..
Why AS curve is 45 degree?
The reason why these diagrams have this 45-degree line is that for every point on the line, the value of whatever is being measured on the x-axis is equal to the value of whatever is being measured on the y-axis. … Equilibrium national income occurs where Y = E, and this would be every point on the 45 degree line.
What is the slope of a 45 degree line?
Here the slope of the road between the two points is simply described as the ratio of the altitude change to the horizontal distance between any two points on the line. Thus, a 45° rising line has a slope of +1 and a 45° falling line has a slope of −1.
What macroeconomic relationship is described by the 45 degree line?
The equilibrium in the diagram occurs where the aggregate expenditure line crosses the 45-degree line, which represents the set of points where aggregate expenditure in the economy is equal to output, or national income. Equilibrium in a Keynesian cross diagram can happen at potential GDP—or below or above that level.
How do you find the slope of AE?
The slope of the aggregate expenditures curve, given by the change in aggregate expenditures divided by the change in real GDP between any two points, measures the additional expenditures induced by increases in real GDP.
When the consumption schedule crosses the 45 degree line?
A decrease in disposable income. At the point where the consumption schedule intersects the 45-degree line: the APC is 1.00.
Does curve shift to the left?
The LM curve shifts right (left) when the money supply (real money balances) increases (decreases). … Then imagine a fixed MS and a shift upward in money demand, leading to a higher interest rate, and vice versa. The IS curve shifts right (left) when C, I, G, or NX increase (decrease) or T decreases (increases).
Why as is 45 degree?
The 45-degree line represents an aggregate supply curve which embodies the idea that, as long as the economy is operating at less than full employment, anything demanded will be supplied.
Is curve a diagram?
The goods market equilibrium schedule is the IS curve (schedule). It shows combinations of interest rates and levels of output such that planned (desired) spending (expenditure) equals income. The goods- market equilibrium schedule is a simple extension of income determination with a 45° line diagram.
Is curve a formula?
Algebraically, we have an equation for the LM curve: r = (1/L 2) [L 0 + L 1Y – M/P]. r = (1/L 2) [L 0 + L 1 m(e 0-e 1r) – M/P]. … This equation gives us the equilibrium level of the real interest rate given the level of autonomous spending, summarized by e 0, and the real stock of money, summarized by M/P.
What is Keynesian equilibrium?
KEYNESIAN EQUILIBRIUM: The state of macroeconomic equilibrium identified by the Keynesian model when the opposing forces of aggregate expenditures equal aggregate production achieve a balance with no inherent tendency for change.
What is the equilibrium level of income in this Keynesian model?
According to the Keynesian theory, the equilibrium level of income in an economy is determined when aggregate demand, represented by C + I curve is equal to the total output (Aggregate Supply or AS).
Who developed the Keynesian cross?
SamuelsonThe Keynesian Cross, a formulation of the central ideas in The General Theory, appeared as a central component of macroeconomic theory as it was taught by Samuelson in his textbook, Economics: An Introductory Analysis. The Keynesian Cross plots income on the horizontal axis and expenditure on the vertical axis.
Why is it called IS curve?
The name “IS curve” derives from the property that it represents that desired investment equals desired saving.
Is curve a feature?
Properties of IS Curve: Summary: (i) The IS curve is the equilibrium combinations of income and interest rate such that the product market or goods market is in equilibrium. … The IS curve will be relatively steep (flat) if investment is less (more) sensitive to interest rate changes.
What is the Keynesian cross model?
The expenditure-output model, sometimes also called the Keynesian cross diagram, determines the equilibrium level of real GDP by the point where the total or aggregate expenditures in the economy are equal to the amount of output produced.
What is the IS curve?
The IS curve depicts the set of all levels of interest rates and output (GDP) at which total investment (I) equals total saving (S). … The intersection of the IS and LM curves shows the equilibrium point of interest rates and output when money markets and the real economy are in balance.
Is the curve horizontal?
The IS curve is downward sloping. When the interest rate falls, investment demand increases, and this increase causes a multiplier effect on consumption, so national income and product rises.
