Those students who are studying there from sir live are most lucky students but we are also lucky that he support us by RU-vid 👍🏻 Thanks a lot sir bcoz this unit is creating problem to learn and understand but the way you teach makes things easier 💖😊
i don't usually comment on videos, but hats off to this man!! this is hands down the best video for this aggregate, everytime i tried to do this chapter i would never understand anything but while watching this video i didn't even want to take a break it was so damn interesting! all my doubts and worries related to this aggregate are gone and all thanks to rajat sir!
Notes: 1. Aggregate demand- AD refers to total value of final goods and services which all the sectorsr of economy are planning to buy at a given level of income during a period of one accounting year 2. Autonomous consumption- Consumption at zero level of income 3.Consumption curve Consumption curve is a upward sloping straight line curve Upward because income and consumption both are in positive relation Straight line curve because the proportionate change in consumption is constant at every level. 4. Important points about AD curve • AD = C+I •There's always some positive consumption even when the income is 0 • Slope of consumption curve- upward • Slope of autonomous investment curve- Horizontal straight line parallel to x axis • Starting point of AD curve- it never starts from 0 because of autonomous consumption and autonomous investment. • Slope of AD curve- upward
*Aggregate Supply* 1.Aggregate Supply is the flow of goods and services as planned by the producers during a period of time. 2. Important points about AS: • AS is equivalent to National Income • AS= Y= C+S,Where c is consumption,s is savings • AS curve or Y = C+S line is a 45° line 3. Savings at 0 level of income is called dissavings
*Consumption function* 1. Consumption function is the functional relationship between consumption and income. 2. C= f(Y) 3. Important observations: • Consumption curve starts from a point which us above origin this is because of autonomous consumption. • Slope of consumption is positive sloping. • when yc (ie. after Break even point) this gap is covered by savings.
*Propensity to Consume* i. APC- Average Propensity to Consume Proportion of Consumption out of Income C/Y • APC can be more than 1( because of autonomous consumption) • APC can be 1( break even point or s=0) • APC can be less than 1 • APC can never be 0 • APC falls with increase in income ii. MPC- Marginal Propensity to Consume Proportion of change in Consumption due to change in Income ∆C/∆Y MPC= 0 when there's no change in Consumption MPC= 1 when there's same proportionate change in Consumption •MPC is lies between 0-1 • MPC of poor is more than that of rich • MPC falls with successive increase in income
*Savings Function* 1. It is the functional relationship between savings and national income. 2. S= f(Y) 3. Important observations • Saving curve starts from negative axis because of positive consumption even when income is 0. • Slope of saving curve- positive slope because of positive relationship between income and savings. •When savings= 0 it indicates break even point • After Break even point savings is positive
thank you sir for your support you helped us during the lockdown and now all main subject exams are over now I may not return but I hope your channel grows even more and you live a happy and good life I will miss you
I mean seriously I couldn't understand this chapter and just by going through this video... I'm so confident ❤ Thank you so much sir, much respect to you🙏
Before watching this vedio this unit seems to me the most difficult although i was having tutiond but I didn’t get this chapter but after watching your video sir i have understood each and every term in this chapter thank you so much sir god bless you ❤🙌🏻
I never comment on any video its just not my thing but i need to tell you that how much we appreciate your efforts . Like i am a maths student so i dont study any subject normally . Its just 10 - 15 days before exam that i get to it . And i just ho through your videos and solve the questions and i always get the best grades in the class . People attending multiple coaching asks me where do you go and i am like why do you need to go somewhere when you have this guy on your phone anytime
Thankuu so mch sir,, 🙏🙏🙏jo chapter aaj tak nhi smjh aaye the vo aapne ek din m itne ache se smjh aa diye... Schi bhot confidence mila h ki hnn ab ppr acha hoga thankuu sir☺☺
Sir ji apko dil se bada vala thankyou dhanyawad ❤❤ I was literally tensed jab bhi yeh chap acha tha mai hamesa chor kar aata tha paper m but ab board h... Mujhe apki yeh video mili jisse mujhe pura acha se smaj aa gya ❤❤ you are god for us
Wow amazing first of all I got very less marks in economics and I was very afraid of this subject I am in humanity student of class 12 I really wanted to change this subject and want to add another subject in place of this but my mother told me to continue studying this subject because this is very helpful to learn about this economics things but I was very very very afraid and I didn't knew what to do I was an average student from my childhood but now I want to get good marks in class 12 that's why I am trying to focus on my studies very much and yeah economics now is seemingly for me to be easy I am understanding the concepts of the chapters and as well as formulas diagrams I guess economics in class 12 is very easier than class 11 although I haven't checked pyqs or didn't done any question analysis or didn't practice any questions I will continue this after finishing the whole macroeconomics I guess I will get full marks in this subject I am getting very confidence by watching your amazing videos thank you very much for making this types of videos and continue making this types of helpful videos in future thank you very much love love 💗
Rajat Bhaiya aap aise hi hr chap smjhao aise hmlog chahte hue v chapter ko ignore nhi kr skte likhna hi pdega pdhne k sath sath 😅mja aa rha h aise hi ❤
This is the best one shot of this chapter! I understood everything..!!! Tho I studied from GNG series too but this one was of another level>>> Thank you so much sir!❤
Point1Consumption curve strt from a point above orign this because of autonomus consumption point 3 when (income is less then consuption then this is disaving point 4 when income is equal consmption at this time saving is zero 5 when income more then consuption gap fill by saving propensity to consume avrage proensity consume mp marginal propensity to save...
Sir your video is very helpful, I am from Assam board but l often watch your videos and I understood very easily your all videos. Really you are the best teacher for all of us❤😊

Last me jub sir non coching Kara rhe the jab mujhe lag ra tha ki meri akele extra classes Li ja rhi h, sirf un baccho ki awaaz ne hi coaching ka mahaul bana rkha tha l, but ab class aur ch dono khatam 😂❤❤ ❤❤❤❤❤
Thanku so much sir g You r very hard working for us really I am lucky .......... I have no words how I express my views to you thanku so much sir g 💞❤😍
