 In this module, we are going to study the consumer behavior preferences ordering property non-satiation. This property is basically shows the relationship between the quantities of the goods or the services that a consumer is going to prefer in one bundle and its place in the preference ordering. It means the consumer who is preferring a lot of assets, he decides a relationship between them and on the basis of that relationship, we can take the share to the other person. So, if we look at the positioning in that, then who is better, who is worse, if we look at it, then we will say that this will be in non-satiation and in other words, one more thing is that the consumer can never be completely satisfied. If we do not say that the asset that he is taking through it, the desire or demand of it is not complete, it is definitely in that time frame but it is always demanding for more than the amount, so if we say in other words that non-satiation means that the consumer will always demand more than the amount of assets, if he is taking some quantity today, then it is his satisfaction but he will always want that if I get more than this, then it is better, then if I get more than that, then it is better. So, if we look at it, then our consumer's natural desirability expresses it. And if we look at this property, then it is the relationship between our goods that expresses it and in that non-satiation, if we look at it, then it means that if in front of the consumer, there will be two bundles in which one will have less assets and the other will have more assets and if there are two bundles, then the bundle in which the quantity is more, it will attach more higher value or positive value to it. And that is why the one with more assets will always prefer the bundle in which the amount of assets will be less. And if we cannot give preference, then if we say that if he is more of at least one good and no less of any, then at least we will say that he or she will give at least preference and if he does not give preference, then at least he or she will have equal between them and he or she will not give less. And this means that a lot of assets that we see in the market, we can definitely say about preference that the consumer has said it better and the consumer has rejected it. But we cannot say that any commodity tag can be bad. And if we say in the other form that any commodity that is present in the market, it can be for one consumer, it can be very preferred for that and it can be non-preferred for the other. So for the non-preferred, it is giving a bad impact but that good is not bad. It is exactly the same way that a lot of music can be liked by some people but in the same way, if there is a patient in Sai's house, then the music that is seen in the form of a lot of noise, it can be a vice for that but in the form of bad, we can call it logically but in the language of economics, no commodity is anything that we can call bad. So somewhere, there is a value of every commodity and the consumer is selecting it based on that. So if we look at the value of the satiation, then the quantity of that attached value will always be preferable. Now if we look at a graph that we are drawing, under that graph, if we have drawn on the x axis that this is our commodity and here we have drawn the other commodity which is burning in this form, now we will see that one point of intersection of these two commodities on which we go and say that the point of both commodities on this point which he purchased or the bundle which he preferred. Now if we look at this point, then we have drawn an indifference curve that we have drawn like A, B, C but now we have shown B point on this point. Now if we talk from here, then we have a range of this indifference curve on which our combinations are of x1 and x2. The combination of one x1 and x2 can be here, the other can be here, the third can be here. In the same way, these are various combinations and among those combinations, now the thing that is missing here is our hypothetical line of which if we say budget line. Since if we look at the budget line, then it is only tangent to this point, then this was our equilibrium point. Now on the left side of this point which is our block or if we look at it, then all the points of indifference sets are always on the left of this A and C. So all these things are found here. And in the same way, if we look at it, then our point B is found here on the right side. Now if we look at it, then point B is the out of reach of the consumer. And if I draw a hypothetical curve that might be that he wants to purchase, then if we look at this hypothetical curve which I have drawn of an indifference curve or consumption bundle, then this B is preferred to A and C because it is present at a higher level. But since it is not in its range or its budget, then the placing on the right side will be preferred to A and it is now in the form of non-satiation that he has purchased these things and he is satisfied up to this point. But since the consumer is having the more wishful thinking to attain this B commodity which might be that he wants to purchase somewhere in the future, then he will show his non-satiation. And the things which he has already attained, which are all present here, this is an attained bundle to him. And because of this non-satiation, if we say for the future, this is his wish or his bundle which is giving him non-satiation. And if we look at this, apart from this bundle, if we look at this indifference curve as well, then if he is taking commodity above this one point, X1 and X2, and if he wants to purchase more than X1, if I draw a line here, perpendicularly, then he has taken X1 commodity till here. Now if he wants to purchase more commodity of X1, then he has to come to this point while doing downward movement. If you look here, then X2 commodity was this much, which had to come to this point while leaving it. So if you look here, if the consumer sacrificed the commodity of X2, then he has gained more commodity of X1 from here to here. So if we look at this non-satiation assumption, it shows our movement of consumer from one combination to other. And at the same time, if he wants to purchase more commodity of X1, then he should be ready to sacrifice at least that thing which is already present in his hand. So in this regard, the property of an indifference curve, we say that the set of indifference is made at a particular point, it cannot be much wider than that. So if we talk about this set, then we have only shown the combination of these points. If I say after the wider, then we cannot show it so much wider in this form because then we can see its various combinations more. And in the same way, we say that it cannot be much thicker in the form and that is why we have to show it in the geometrical form or in the graphical form. So we are always expressing it from a point to a point that either this combination is at this point or this combination is at this point or this combination is at this point. So that is why, because it expresses our different quantities, then this is our property of consumption or indifference curve. If we look at it, then it is expressed at this point. And along with that consumption curve, the movement which is possible through substitution, then the trading of between the goods or the trading of between the bundles are expressed through this property.
