 shift in production possibility frontier and we will explain this in the detail with the help of graph as we have already explained that the production possibility module that can shift it can shift either inward either it can shift outward and here if we have to explain that how it shifts to the outward or the inward so we can explain through the form of the graph and in the graph this is our basic level of production possibility frontier and once it moves to the right side and this movement to the right side will be the outward shifting and this outward shifting is possible through the increase in the resources of production these resources of production when we say these are not evident in this graph so if we say it in other words then we have the production possibility that it is not possible until we have the production possibility and where do we get the production possibility if we see it here then we will explain that if we explain an isoquant in which we say that this is good x and good y produce we say this good x in the form of industry then we can say that if there are robots here and if we say that the industry is producing the cars and if we take the example of agriculture then we can say that in the same resources here if there is maize and here in the same resources we can be born and see these two things if we say so when we say the two goods so we took the example of two goods now for production sectors if we go then we include only two factors of production if we do so here is labor and here is capital this available labor or available capital which is present in the economy using it if we draw a constant level of production and this constant level of production or equal level of production isoquant this isoquant if we show various combinations now this various combination definitely two outputs that can be robots and the cars point A point B and point C now if the form A is producing these things then it will be in this form and similarly if the form B is also working then we draw the isoquant so now you see we can draw the same face now if we see in this then I have drawn a higher level of the isoquant this is the level of the isoquant means these are the points of the isoquant which can be produced on the farm with available resources and what will be its equilibrium level that will be where its budget line crosses actually this budget line that gives the level of the available resources which we can explain that is called the cost that is equal to the wage into labor plus amount of capital multiplied by its price so this budget line it gives us the total limit of the production possibility frontier so when available cost or available budget or resources of the economy it will increase from this level to this further level and again to this further level and can be to this further level so we can say that our output it will increase from this production possibility frontier to this and similarly if we come backward from the higher levels in which we see that our level of production is decreasing why is it happening because our amount of labor which was available at this point instead of that it came at this point and so the shifting that will be through the inward shifting and now if we explain these two points then we see that this production possibility frontier if we show the shape of the edge worth box in which one consumer A will be on this side consumer B is on this side and both of these iso-quants are facing each other in this way moving as much as available labor is on all of our x axis and as much as available we have the capital is on y axis so if I explain this point of x axis then this means that this labor is two parts of it from zero to here the labor is that one production has been used and the one after that is the firm B is using in the same way if we talk about the capital and we will do the part of it then we will say that this amount of capital is on this side so the firm B is using and till here the firm A is using and iso-quants of these two firms when they intersect each other and behind that their budget line it also intersects this will give that point that will be the efficient point or we can say equilibrium point but it will not be global efficient so we have a lot of such points available here which if we say then they give equilibrium but these will be inefficient points and the maximum efficient point will be the one that the production possibility frontier curve will be above and this will be globally efficient and this will be showing its equilibrium so when the resources or the factors of production they will enhance so the total possibility frontier it will shift from this so now we will have a next edge worth like this and our possibility will lead to this so these are the various forms through which we can explain the inward shifting of the production possibility frontier or the outward shifting of the production possibility frontier
