Indifference curve budget line

Indifference Curve

Because combinations X and W are equally satisfactory, and because Ms. If you move "off" an indifference curve traveling in a northeast direction assuming positive marginal utility for the goods you are essentially climbing a mound of utility. Transitive with respect to points on distinct indifference curves.

Because now our optimal spent is this point on our new budget line which looks like it's about, well, give or take, about 10 pounds of fruit. So this axis, let's say this is the quantity of chocolate.

In this case of a normal good, the income and substitution effect reinforce each other — both leading to lower demand. And this is in pounds. Bain spends 2 days skiing and 3 days horseback riding per semester. She is thus willing to give up 2 days of skiing for a second day of horseback riding.

Goods are distinguished according to their characteristics: Second, quantities are measured on a continuous scale: Advanced versions of the model, based on more realistic assumptions, have been designed to cope with non-standard real world situations.

The slope of an indifference curve in absolute valueknown by economists as the marginal rate of substitutionshows the rate at which consumers are willing to give up one good in exchange for more of the other good.

People buy less for two reasons Income effect. The consumer has ranked all available alternative combinations of commodities in terms of the satisfaction they provide him.

Indifference curves and budget lines

And I get my quantity of chocolate is equal to 20 minus 2 times my quantity of fruit. Here, indifference curve B is preferred to curve A, which is preferred to curve C. Is it more humane to die by wallops from a Cambodian pickaxe handle than by a bullet from a German Mauser.

We draw a new budget line parallel to B2 but tangential to the first indifference curve. For example, if the price of petrol rises, consumers may not be able to afford to drive as much, leading to lower demand.

Some worry that indifference curves erroneously lead economists to adopt cardinal utility functions; this criticism is unfounded since indifference curve analysis utilizes monotonic transformations to preserve ordinal rankings.

An isoquants shows all those combinations of factors which produce same level of output. The point at which utility is maximized must be on the highest indifference curve consistent with condition 1. If we spent all of our money on fruit at the new price, we could buy 20 pounds of fruit.

First of all, in the simplified model the number of goods available on the market is not infinite. Let's say per month. By focusing on B-3, we are examining the effect of price change — ignoring any income effect.

You can now buy less of good Bananas. Price-taking The second assumption underlying the simplified model maintains that a single consumer takes prices 'as they are' and does not bargain for a better price.

Bain devotes more and more time to horseback riding, the rate at which she is willing to give up days of skiing for additional days of horseback riding—her marginal rate of substitution—diminishes.

It will turn out that, if a group of simplifying assumptions are met, the best choice for the consumer can be represented as a bundle in the budget set that also belongs to the highest attainable indifference curve.

This assumption makes indifference curves continuous. The point at which utility is maximized must be within the attainable region defined by the budget line. We would, assuming that we had data on all of these indifference curves, we would find the indifference curve that is exactly tangent to our new budget line.

For a single consumer, this is a relatively simple process. I'll do it in blue, would look like this. The budget line intersects with the point (2,2) along the pink indifference curve indicating that we can hire Chris for 2 hours and Sammy for 2 hours and spend the full $40 budget, if we so choose.

But the points that lie both below and above this budget line also have significance. An isoquant (derived from quantity and the Greek word iso, meaning equal) is a contour line drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs.

While an indifference curve mapping helps to solve the utility-maximizing problem of consumers, the isoquant mapping deals with the cost-minimization problem of producers. The lower left-hand corner represents the origin for consumer 'A' and the upper right-hand corner represents the origin for consumer 'B'.

Person A's preferences (indifference curves) are convex to the origin O B's preferences are convex to O B. Budget constraints give a straight line on the indifference map showing all the possible distributions between the two goods; the point of maximum utility is then the point at which an indifference curve is tangent to the budget line (illustrated).

On an indifference map, higher indifference curve represents a higher level of satisfaction than any lower indifference curve. So, a consumer always tries to remain at the highest possible indifference curve, subject to his budget constraint.
