What causes a shift in indifference curve

In short, the slope of the indifference curve changes because the marginal rate of substitution

What does indifference curve depend on?

Many core principles of microeconomics appear in indifference curve analysis, including individual choice, marginal utility theory, income, substitution effects, and the subjective theory of value. Indifference curve analysis emphasizes marginal rates of substitution (MRS) and opportunity costs.

Can an indifference curve cross itself and why?

No, an indifference curve cannot cross itself. It represents the bundles of goods which a consumer is indifferent between having at a certain price of each good. The implication of the satisfaction level at all points is that it is the same.

What happens when you move down an indifference curve?

Most indifference curves are usually convex because as you consume more of one good you will consume less of the other. So, MRS will decrease as one moves down the indifference curve. This is known as the law of diminishing marginal rate of substitution.

Why is an indifference curve downward sloping?

Indifference curves slope downwards. The only way an individual can increase consumption in one good without gaining utility is to consume another good and generate the same amount of utility. Therefore, the slope is downwards sloping. Indifference curves assume a convex shape.

What is slope of indifference curve?

The slope of the indifference curve is the marginal rate of substitution (MRS). The MRS is the amount of a good that a consumer is willing to give up for a unit of another good, without any change in utility.

Who gave the idea of indifference curve?

Developed by the Irish-born British economist Francis Y. Edgeworth, it is widely used as an analytical tool in the study of consumer behaviour, particularly as related to consumer demand.

What does a flatter indifference curve mean?

If the indifference curve (or slope) is flat, then the MRS is low. This means the consumer is willing to give up very little good y for an additional unit of good x.

Why does MRS decrease?

Well MRS decline continuously in IC curve because of law of diminishing marginal utility. Means when the consumer consumes more and more of good 1 then his marginal utility from another good keeps on declining and he is willing to give up less and less of good 2 for each good 1. Thats why MRS decline in IC curve.

What happens to MRS when consumer moves downward along the indifference curve?

MRS means Marginal rate of substitution it refers to that rate at which consumer is willing to subsitute a good for other one… It tends to decline when we move along Indifference Curve… At point A and B consumer is willing to give up 1.5 units of good Y for one more of good X…

Why indifference curve is not concave?

Indifference curves are convex to the origin because the increase in utility from an increase of a single unit of any product does not remain the same. … This is called a decrease in marginal utility and is the reason why indifference curves are convex.

Can indifference curves be horizontal?

4. The slope of an indifference curve is negative, downward sloping, and from left to right. … So an indifference curve cannot be horizontal. In Figure 4 (C) the indifference curve is shown as vertical and combination В is preferred to A as the consumer has more of Y and the same quantity of X.

Are indifference curves always parallel?

ADVERTISEMENTS: (8) Indifference curves are not necessarily parallel to each other. Though they are falling, negatively inclined to the right, yet the rate of fall will not be the same for all indifference curves. … This is so because indifference curves are assumed to be negatively sloping and convex to the origin.

Why is it impossible for an indifference curve to slope upwards?

A set of indifference curves can be upward sloping if we violate assumption number three; more is preferred to less. When a set of indifference curves is upward sloping, it means one of the goods is a “bad” so that the consumer prefers less of that good rather than more.

Why does indifference curve slopes downward and convex to the origin?

ii Indifference Curve is convex to the origin : Because it is assumed that Marginal Rate of Substitution falls continuously as the consumer moves downwards along the curve. It is due to the Law of Diminishing Marginal Utility.

How many of the following will cause a shift of budget line towards right?

If prices of the two goods remain unchanged, then with an increase in income, budget line of the consumer shifts to the right. Similarly, when there is fall in the prices of both the goods X and y and if the income of the consumer remains unchanged, then also the budget line will shift to the right.

What happens to MU when Tu is maximum?

When MU is Zero, TU is the maximum and it is the point of maximum satisfaction. i.e., point of satiety. When Mu becomes negative, total utility starts diminishing.

Who is the father of economics?

The field began with the observations of the earliest economists, such as Adam Smith, the Scottish philosopher popularly credited with being the father of economics—although scholars were making economic observations long before Smith authored The Wealth of Nations in 1776.

What happens if indifference curves cross?

The indifference curves cannot intersect each other. It is because at the point of tangency, the higher curve will give as much as of the two commodities as is given by the lower indifference curve. … Similarly the combinations shows by points B and E on indifference curve IC1 give equal satisfaction top the consumer.

What happens at the consumer's optimum?

What happens at the consumer’s optimum? a. The slope of the indifference curve is equal to the slope of the budget constraint. … It is still possible for the consumer to increase his consumption of both goods.

What is convexity of indifference curve?

Convexity of indifference curves implies that the marginal rate of substitution of X for Y falls as more of X is substituted for Y. Thus, indifference curves are convex to the origin when principle of diminishing marginal rate of substitution holds good and which is generally the case.

What is price effect?

The price effect is a concept that looks at the effect of market prices on consumer demand. In general, when prices rise, buyers will typically buy less and vice versa when prices fall. … This is demonstrated by a standard price to demand curve.

What is MRT in economics?

The marginal rate of transformation (MRT) allows economists to analyze the opportunity costs to produce one extra unit of something. … MRT is the absolute value of the slope of the production possibility frontier.

Why should MRS diminish for a stable consumer's equilibrium?

Diminishing marginal utility clearly states that if the consumption increases, the utility derived from the additional units goes on decreasing. So, MRS should be diminishing as additional consumption of A results in a fall in marginal utility due to that the consumer will not be willing to increase its consumption.

What is steeper and flatter?

Calculating Slope Suppose the slope of a line were to increase. Graphically, that means it would get steeper. Suppose the slope of a line were to decrease. Then it would get flatter. … A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line.

Can Isoquants cross?

Two isoquants can not intersect each other. An isoquant is convex to its origin point. An isoquant is oval-shaped.

What is flatter and steeper curve?

Flatter demand curve of elasticity of demand shows that slightly change in the price of the commodity lead to a larger change in the quantity demanded. Steeper demand curve of elasticity of demand shows that large change in the price of the commodity lead to a smaller change in the quantity demanded.

How does MRS impact the shape of IC?

Answers. Ans: .. MARGINAL RATE of SUBSTITUTION (MRS) shows the slope of the INDIFFERENCE CURVE (IC).

What is Hicks substitution effect?

In the Hicksian substitution effect price change is accompanied by a so much change in money income that the consumer is neither better off nor worse off than before, that is, he is brought to the original level of satisfaction. … Thus the Hicksian substitution effect takes place on the same indifference curve.

Can indifference curve have kinks?

The indifference curves cannot have kinks.

Can IC be parallel?

Secondly, the rate of substitution between two commodities need not be the same in all indifference schedules. From this it follows that IC may be drawn in any way parallel to each other or otherwise. The only condition is that the two IC should not touch or cut each other.
