One property I can say of this market equilibrium it maximizes the gain to the society. Mind you one thing you should always keep in mind that this scenario is valid only when you have large number of buyers and large number of sellers. Later on, we will learn this thing in a more technical way in more concrete manner;...

Lecture87_Economic_Terminology_Opportunity_Cost.txt
Now, we are going to talk about some economic terminology before we move to another topic. So, the first is we are going to talk about opportunity cost and also sunk cost. Opportunity cost is the value of best alternative foregone. Foregone. Let us take it is not very clear from the definition but let us take some exam...

Lecture78_Average_and_Marginal_Product_of_Labour_APL_MPL.txt
So, now let us take numerical example, what we have here is let say capital as we have fixed at 5. And here we have labour and, here we have output. So, let say let us take some example, labour is 0, it is possible that to produce something, but we will take that here in this example when labour is 0 output is also 0. ...

Lecture62_An_Example_with_Quasi_Linear_Preferences.txt
Now, I am going to give you another problem where we will use mathematical, some mathematical concept that we have learned to solve, that one is also difficult. Now, we are talk, going to talk about something called quasi linear preferences, let us say in 2 good world, preference is called quasi linear if utility funct...

Lecture05_Rationality_Self_Interest_and_Optimization.txt
Let us endow our individual with 2 properties. The first is rationality, and the second is self-interest. It is not exactly endowment; it is like if we want to study individual systematically then we say that the individual is rational. Let us say if someone is acting irrationally. Someone is acting very, very irration...

Lecture25_Perfectly_Elastic_and_Perfectly_Inelastic_Demand.txt
We looked at elastic zone of the demand curve, inelastic zone of the demand curve, and in the middle, we get a point where demand is unit elastic that is what we have discussed. Now, let us discuss the 2 extreme cases, the one extreme case is perfectly elastic, what it means is that you change price by tiny bit amount,...

Lecture07_Introduction_to_Demand_Supply.txt
Welcome again to NPTEL lectures on microeconomics. Today we are going to discuss demand, supply and market equilibrium. I will begin with a simple story. A very simple story, a short story and then I will talk about some facts. And we will discuss why do we observe such kind of things in our society in our economy. So,...

Lecture54_Utility_Maximization.txt
So, far we have been talking about different building blocks of consumer theory or consumer behaviour. We started with consumption set. We started with consumption set then; we talked about feasible set or affordable set, from there we moved to preference to describe taste and liking of an individual. And what we did? ...
Microeconomics
Lecture26_More_on_Elasticity.txt
Now, what we have done is we have studied price elasticity of demand. Similarly, one can study price elasticity of supply. And what is price elasticity of supply? Again, remember what is elasticity basically? Proportional response It measures the proportional responsiveness of one variable with respect to proportional ...

Lecture31_Incidence_of_Tax_Four_Extremes.txt
Now, we already have learned the concept of elasticity. Now, I am going to talk about certain extreme scenario and I will let you to interpret what happens in the middle cases. Now, I would say in all these cases just it does not matter whether it is imposed on buyer or it is imposed on seller, but just to understand l...

Lecture11_Factors_Affecting_Demand.txt
Factors affecting the demand function. Can you think of any factor that affect the demand function? Some we have already covered, some we have covered in today’s class. The first session we have covered, can you think of some of the factors? Income income. Income how does it impact, what happens? Income increases deman...

Lecture41_Preferences_as_a_Mathematical_Construct.txt
We talked about three properties and those three properties were completeness, reflexivity and transitivity, and what did we say that if our preference satisfies these three properties then we can talk about our choice, our selection of a particular bundle of good in consistent fashion. And I had also given you an exam...

Lecture46_Properties_of_Preferences_Continuity.txt
Now, as we have seen that when we have finite number of consumption bundle in the consumption set, it is very easy to rank, we do not need any more we can rank them. But what we have remember go back to your, the definition of the properties of consumption set. What does it imply? That consumption set would have infini...
Microeconomics
Lecture34_Budget_Line_and_Budget_Set.txt
So, we talked about 4 basic building blocks of consumer theory we talked about consumption set or choice set that is all about what you can conceive in your mind. It is not limited by any of the constraints that you face, it is all about what you can conceive in your mind and whatever bundle or coming that is bundle is...

Lecture61_Perfect_Complements.txt
So, the example I just gave had 2 goods, they are perfect substitute for each other and what does it mean when I say they are perfect substitute for each other. It simply means that 2 goods are that, that 2 goods are perfect substitute for a consumer. Of course, we should not forget that we are talking about a particul...

Lecture79_More_on_APL_and_MPL.txt
Ok let us take this graph again on y axis we have and on x axis we have labour input and of course, we are taking capital as fixed. So, we are not putting capital on any axis; so, what we have here is that output is going up as labour is increasing till this point and then its starts decreasing. That is why when we say...

Lecture14_Factors_Affecting_Supply.txt
Let us look at the factors affecting the supply curve. We have learned what do we mean by supply curve. Supply curve, just to remind you that supply curve is a curve that gives the combination of market price and at that price seller’s willingness to supply certain quantity of good. So, now let us look at the factors a...

Lecture90_Diminishing_Marginal_Product_Vs_DMRTS.txt
So, we studied about diminishing marginal rate of technical substitution and we also studied diminishing marginal product. So, let us see do not get confused between these 2 terms, because it is very easy to get confused. So, let us look at graph, and try to understand how these 2 things are different. So, first, let m...

Lecture94_Cost_Minimization_Few_Examples.txt
So, now let us solve some mathematical we have looked at it graphically, some problem we will solve graphically and then we will derive the mathematical way to solve this cost minimization problem. What we have done? Let us say where production technology is, let us say production technology is given by Y or Q that is ...

Lecture71_An_Application_Subsidy_Vs_Direct_Benefit_Transfer.txt
Now let us that is the last topic in the consumption theory. Let us do an application a simple application. See in the budget our finance minister announced that slowly at least for some particular goods government would move from specific subsidy to keys cash transfer. Ok and Bihar government is already doing it for s...

Lecture84_Elasticity_of_Substitution.txt
Now, what we have is the elasticity of substitution? What we have done; let us look at MRTS. What is a MRTS? MRTS is basically slope of isoquant and this is MPL divided by MPK. Although, we have not done, but look at this isoquant; when you want to produce we will do this in more detail later on that the concept that I...

Lecture35_Factors_Affecting_the_Budget_Line.txt
The example that I just gave you there also budget line you know is combination of 2 straight lines, but its it is not always true that the budget line is a line, it can be a curve. So, in that case we call it a budget curve rather than budget line for example, the price of coconut is changing with each unit of coconut...

Lecture98_Cost_in_Short_Run_TC_FC_and_VC.txt
What we are going to do now? For time being, we are going to move from long-run to short-run cost curves in short-run and how short-run is different from long-run. Sir at least one of the variables does not change. One of the inputs. Input varies input. One of the inputs cannot be varied and so far, we have been talkin...

Lecture96_More_on_Cost_Minimization.txt
So, we saw these three examples and what we try to do, we try to calculate the minimum cost to produce Q amount of output, given the price of 1 unit of capital is r and price of 1 unit of labour is w and of course not just 1 unit, it is 1 unit per unit of time. It can be per day per hour, just we have to be consistent ...

Lecture48_Indifference_Curve.txt
So, what we are getting or let us say by if we abuse this notation little bit what we can say that indifference set is given by x 1 plus x 2 is equal to k. All the bundles which if we add the quantity of good 1 and good 2 we get k would be on the same indifference curve. If we change the value of k we will get a differ...
