Indifference curves and budget lines

An indifference curve is a graph representing two goods that give a consumer equal satisfaction and utility. An indifference curve is a line showing all the combinations of two goods which give a consumer equal utility. In other words, the consumer would be indifferent to these different combinations. Example of choice of goods which give consumers the same utility.

Edgeworthit is widely used as an analytical tool in the study of consumer behaviour, particularly as related to consumer demand. It is also utilized in welfare economicsa field that focuses on the effect of different actions on individual and general well-being. The classic indifference curve is drawn downward from left to right and convex to the origin, so that a consumer who is given a choice between any two points on it would not prefer one point over the other.

Because all of the combinations of goods represented by the points are equally desirable, the consumer would be indifferent to the combination actually received. An indifference curve is always constructed on the assumption econo,ics, other things being equal, certain factors remain constant.

In economics, an indifference curve is a line drawn between different consumption bundles, on a graph charting the quantity of good A consumed versus the quantity of good B consumed.

List of Partners vendors. An indifference curve, with respect to two commodities, is a graph showing those combinations of the two commodities that leave the consumer equally well off or equally satisfied—hence indifferent—in having any combination on the curve. Indifference curves are heuristic devices used in contemporary microeconomics to demonstrate consumer preference and the limitations of a budget. Economists have adopted the principles of indifference curves in the study of welfare economics.

Standard indifference curve analysis operates on a simple two-dimensional graph. Each axis represents one type of economic good.

Along the indifference curve, the consumer is indifferent between any of the combinations of goods represented by points on the curve because the combination of goods on an indifference curve provide the same level of utility to the consumer.

For example, a young boy might be indifferent between possessing two comic books and one toy truck, or four toy trucks and one comic book so both of these combinations would be points on an indifference curve of the young boy.

Indifference curves operate under many assumptions; for example, typically each indifference curve is convex to the origin, and no two indifference curves ever intersect. Consumers are always assumed to be more satisfied when achieving bundles of goods on indifference curves that are farther from the origin.

As income increases, an individual will typically shift their consumption level because they can afford more commodities, with the result that they will end up on an indifference curve that is farther from the origin—hence better off.

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. Indifference curve analysis typically assumes all other variables are constant or stable. Most economic textbooks build upon indifference curves to introduce the optimal choice of goods for any consumer based on that consumer's income.

Classic analysis suggests that the optimal consumption bundle takes place at the point where a consumer's indifference curve is tangent with their budget constraint. The slope of the indifference curve is known as the MRS. The MRS is the rate at which the consumer is willing to give up one good for another.

If the consumer values apples, for example, the consumer will be slower to give them up for oranges, and the slope will reflect this rate of substitution. Indifference curves, like many aspects of contemporary economics , have been criticized for oversimplifying or making unrealistic assumptions about human behavior.

For example, consumer preferences might change between two different points in time rendering specific indifference curves practically useless. Other critics note that it is theoretically possible to have concave indifference curves or even circular curves that are either convex or concave to the origin at various points. Consumer preferences might also change between two different points in time rendering specific indifference curves practically useless. Fixed Income Essentials.

What Is an Indifference Curve? Key Takeaways An indifference curve shows a combination of two goods that give a consumer equal satisfaction and utility thereby making the consumer indifferent. Along the curve, the consumer has an equal preference for the combinations of goods shown—i. Typically, indifference curves are shown convex to the origin, and no two indifference curves ever intersect.

Equilibrium Quantity Definition Equilibrium quantity is when there is no shortage or surplus of an item. Supply matches demand, prices stabilize and, in theory, everyone is happy. Law of Demand Definition The law of demand states that quantity purchased varies inversely with price. In other words, the higher the price, the lower the quantity demanded. Welfare Economics Welfare economics focuses on finding the optimal allocation of economic resources, goods, and income to best improve the overall good of society.

Quantity Supplied The quantity supplied is a term used in economics to describe the amount of goods or services that are supplied at a given market price. Partner Links. Related Articles.
