What do you mean by IS curve?
The IS curve shows combinations of interest rates and levels of output such that planned spending equals income. ‘OR’ The IS Curve represents various combinations of interest and income along which the goods market is in equilibrium.
Why is it called the IS curve?
The name “IS curve” derives from the property that it represents that desired investment equals desired saving. i(r)=[y−t −c(y)] + (t −g). The left-hand side is desired investment.
WHAT IS IS curve and how it is derived?
The IS curve is derived from goods market equilibrium. The IS curve shows the combinations of levels of income and interest at which goods market is in equilibrium, that is, at which aggregate demand equals income.
How do you find the IS curve?
What is the IS and LM curve?
The IS-LM model appears as a graph that shows the intersection of goods and the money market. The IS stands for Investment and Savings. The LM stands for Liquidity and Money. On the vertical axis of the graph, ‘r’ represents the interest rate on government bonds.
What are the properties of IS curve?
The IS curve slopes downwards to the right. Or it has a negative slope. Its slope depends on the saving function and investment function. The IS curve will be relatively steep (flat) if investment is less (more) sensitive to interest rate changes.
What is the slope of IS curve?
The slope of the IS curve also depends on the saving function whose slope is MPS. The higher the MPS, the steeper is the IS curve. For a given fall in the interest rate, the amount by which income would have to be increased to restore equilibrium in the product market is smaller (larger), the higher (lower) the MPS.
What causes the IS curve to shift?
Any change (decrease in government consumption, increase in taxes, decrease in consumer confidence – proxied by c0) that, for a given interest rate, decreases the demand for goods creates a shift of the IS curve to the left.
Why is IS curve downward sloping?
Downward-Sloping IS Curve
When the interest rate falls, investment demand increases, and this increase causes a multiplier effect on consumption, so national income and product rises.
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 slope formula?
For most functions, there is a formula for finding the slope of a curve, f(x), this formula is called the called the derivative (or sometimes the slope formula) and is denoted f/(x). Recall that we already know the slope of a line g(x) = mx + b is this means that the derivative of the line is g/(x) = .
IS curve a variable?
The IS curve shows the causation from interest rates to planned investment to national income and output. For the investment–saving curve, the independent variable is the interest rate and the dependent variable is the level of income.
On what factors slope of IS curve depends?
Steepness of the IS curve depends on (1) the elasticity of the investment demand curve, and (2) the size of the multiplier. The elasticity of investment demand signifies the degree of responsiveness of investment spending to the changes in the rate of interest.
IS curve a parameter?
A curve in the (x,y) plane can be represented parametrically. The equations that are used to define the curve are called parametric equations.
IS curve a note?
The IS Curve is derived from the negative relation of Autonomous Planned Spending (mainly Autonomous Consumption and Investment) with the level of interest rates, and the positive relationship between the level of Autonomous Spending with the level of real income.
IS and LM curve equation?
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].
IS and LM analysis?
The basis of the IS-LM model is an analysis of the money market and an analysis of the goods market, which together determine the equilibrium levels of interest rates and output in the economy, given prices. The model finds combinations of interest rates and output (GDP) such that the money market is in equilibrium.
What is the shape of LM curve?
The LM curve is upward sloping: given the money supply and the bond supply, an increase in the national income and product raises the interest rate.
Why is indifference curve convex?
The indifference Curve is convex to origin because of decreasing MRS (Marginal rate of substitution). The curve represents the marginal rate of substitution. Hence, option (a) is correct.
What are the five properties of indifference curve?
Characteristics of Indifference Curves

- Every indifference curve to the right represents a higher level of satisfaction. …
- Indifference curves cannot intersect each other. …
- Indifference curve will not touch the axis. …
- Indifference curves are convex to the origin.
