Thank you 😊 sir please make more videos
I will
Sir please cover statistics topics also like probability etc please sir
@@archie15022 okay
Thank you so much. You literally saved my Industrial Organization exam.
Always happy to help
All these videos are extremely informative.These should help student’s enormously. I have below suggestions for creating broader reach: 1. Make Videos shorter - not more than 10 mins 2. Use Microsoft Whiteboard 3. Link each topic to entrance exams, preferably discuss one question from entrance exams on each of your topics in each of your videos Wish you all the best. Keep going.
Many Thanks. I will definitely implement them.
wtf is this topic
I wish I had this video during my post graduation days. Mas Collel was always a little tough to understand.
I also wanted to deliver the content in this manner for a long time😀
Thank you for this video sir! Very helpful.
What is the appropriate reading for this, beyond undergrad varian book?
I will not say, Varian is an appropriate book for this. My suggestion is Satya ranjan Chakravarty Microeconomics
@EcoShibajee yeah found the relevant reading in src yesterday which has a good treatment, thanks for the help though
@@a_visghhwas that's great! but you mentioned only varian that's why misunderstood. You can try solving some of the problems on SWF also, if not already done.
Hello sir!!Ashwath from sahyadri school here,I am studying economics at the ug level at Loyola college(chennai).I needed to understand this topic better and this was really helpful.
Happy to know Ashwath! Please recommend this channel to others also
our university instructor most probably taught linear city model using tirole's book. I have a hard time following that book. So, in what reference is the hotelling's linear city model lucidly explained? Thanks
lucidly means the basic logic behind the result
yeah, so far tirole's portion of vertical and horizontal differentiation models does the job but i find it a bit lacking.
@a_visghhwas Tirole is a classic, I think that’s why everybody takes its name while teaching. But I think, like any classic, Tirole also can not be a book to start a topic
Sir how about jay l devore of probability and statistics?
It is a mid-level book suitable only for problem solving. I guess because it is for Engineering, the approach suffices. It will make workable but not for learning Statistics, as par my view.
How can we practically apply this thing to a firm. For example how can we use all these ppc, gupf to in practical scenario. What if we have mrts of labour to capital in one firm is greater than that of the other one. How can we solve the problem using welfare economics efficiency.
Draw the relevant diagram
Why gupf is not smooth as ppc
GUPF is not constructed in the same way. Each point here corresponds to different edgeworth boxes. So smoothness cannot be derived.
@@EcoShibajee thank you
@@EcoShibajeesir why are UPFs not smooth ? A single UPF are obtained from a single edgeworth box right? So why is there no smoothness
you sir explained it so well. I wish my teacher was a good as you !!! Many thanks!!!!

I know what my friends used to study in their hons. as I have sometimes studied from those books. I can suggest you some of them but I think they may be old references. If you want to know anyway I can suggest. As you may understand I had Eco hons. with Statistics & Mathematics.
Thank you so much sir tomorrow is my presentation it helped me a lot
please share it with others.
Sir please continue uploading videos.
I try but my offline classes take a lot if time. I will try to be more frequent. Thank you very much.
This is a great one-shot video. I have yet to start intermediate micro, but this will prove to be a great resource to me. Thank you for making this and keeping it free for all. What problem book do you recommend to supplement this topic?
Nicholson Snyder
Thank you! To be honest, I have not taught something that is unavailable in books otherwise. But given semester time,it is impossible for one student to find all this & study. I can not charge for that. I teach for entrance & for that I do charge fees.
@@EcoShibajee I cannot speak for other students but personally finding videos like these on youtube being taught by no-nonsense instructors (not necessarily have to be from a entrance point of view) actually calms my anxiety for a completeness in a topic however time consuming it may be and foolish the endeavour is. These videos do a good job streamlining the study.Helps in recapitulation after hitting several books for theory and intuition. I imagine as the semesters progresses I wont have the luxury to even spare time writing a long comment :)
This is a great video. Thank you for making it. Also, are you considering to start a batch who are going to sit for entrances in 2025? :)
Yes. Foundation is 2 year course. Starts from 3rd Sem. In that actually I get more time to teach Economics at an advanced level.
@@EcoShibajeeThank you for replying. Is that starting from the month of june too ?
No. That will start from July. Primarily because the sem exam in some places are still on.
@@EcoShibajee Yes, i was going to ask you that. JU's exams start from 26th June as far as I know.
@@a_visghhwas I also got to know from my current students who are writing their 4th sem exams in JU.
What do you think about Jadavpur Uni?
Did you go through all the universities & institutes details? If you have, then please let me know which among these made you think of JU as an alternative. Then I can share my thoughts better.
Yeah, I went through the video and was curious to see that other than ISIcal, IIFT no other insti from kolkata/bengal being mentioned. I am not from econ just had econ as a minor at iitd, so I don't know enough about the scene, but since you asked I wonder if HCU or Gokhale is better than JU?, and the doubt is based on my personal interaction with faculty, alumni and students from these three insti. Last I heard JU has an avg placement of 10-12lpa, the top percentile of the class end up at good foreign uni for M.S/ Phds, JU has a really good international exchange program. DSE, IITs, IIFT, igidr is filled with ex JU B.A students. Dept has really good faculty and The student faculty ratio is good. JU is insanely cheap. Has a better brand value (NIRF rank, alumni network etc.) Plus the course is very theoretical and maths heavy, like they have basiyan games, moral hazard etc in Undergrad, & highly theoretical and specialized electives are offered in masters (some of which are not offered in HCU/ Gokhale). Anyway would love to know your opinion.
🙂 @FizzWiz2 From my experience of teaching many of them for entrances, I would say that BA is good. But not MA. They still have to go a long way to be professional. In a public platform like this, I would not say more than: "What you heard is correct but its half of the truth." My students studied & studying in all of these institutions, so rest assured, in a more private space I could have shared more. To give you a hint: "Always ask for the proportions as well as absolute number of students getting such offers." Finally, if there is a choice, there is underlying preference ordering🙂
@@FizzWiz2 I saw our brochure of Placement Cell 2022-24. In the Placements of the Class of 2021-23 Highest CTC offered was 16.75 LPA , average CTC 11 LPA and Median CTC 12 LPA but no percentages or figures of heads who were offered the above packages were given.I asked some seniors who implied its close to 100. Its sus as hell for sure. The cell , from what i have heard ,are constantly taking initiative to bring in more recruiters , internships but leaving out the proportion as well as absolute numbers (as sir said) reeks of shrouding the figures for attracting students. Hopefully the reality is more aligned to the numbers in the brochure of JU. Also about the "highly theoretical and specialized electives are offered in masters" some PG students actually visited us who made us aware of the papers/electives which they were not allowed to take. Yes these electives are offered on paper but due to lack of teacher of something they were not optable in the semester. There are was a conflict in the use of computer labs too for PG students which is too embarrassing for a university offering economics to write here.
As I said that these facts are more appropriate to share in a more private mode of communication
speaking broadly (for entrance apart from semester exams) , what is the one proper real analysis textbook do you suggest ? I have picked up Kenneth A. Ross and downloaded the apostol mathematical analysis book yet. The pass course books for real analysis is very shallow and exam oriented. I am puzzled regarding what book to follow.
Your choices are correct
what is the full form of [SRC microeconomics] ?
Satya Ranjan Chakrabarty; Microeconomics
In cournot model we assume that duopolist will decide amount of output which is profitable for him assuming it's rival will keep output constant. Then in cournot equilibrium (diagrammatically) when firm-1 produces a certain output then firm-2 views it and changes the output level... Both are contradictory ! Can you explain ?
not contradictory. just they assume wrong. setai critique e bolbo. there is no learning
Thanks 😊

You are a saviour.
Sir please explain what you did after 11:30
I applied implicit function theorem. First I constructed the implicit functions & then I took total derivative. This is the way you apply the theorem to form the differential equations
Thanx sir ji. Lagta h ki is saal bhi pass ho jaonga😅😅😅😅
if P = 400 - 4q, would the FOC be 400 - 4qi - sum of qj (j not = i) - 10 = 0?
The first order of (400 - 4q)qi will be 400 - 8qi - 4 sum of qj (j not equal to i) - 10. I guess 10 is MC?
@@EcoShibajee thank you!!!!
Thank you for the concise explaination! You opened my eyes to how income tax is not always the best in improving productivity and I can see it clearer now!
Sir please suggest me a best book on money and financial market
Tell me which degree or course you are taking. There are books of different orientation.
@@EcoShibajeeBSc economics honours under CU 6th semester.
Sir can we explain cournot model with mr curve in bcom 1st sem exam
the general culture you give the explanation the way it is described in the class. I suggest you talk to your professor to avoid any confusion.
What if the marginal cost isn't the same for each firm ?
Then we can not use symmetry as different MC will imply different firms. The calculation will be complex & the adjustment process will be little different. With the increase in 'n', the high MC firms will leave as the resulting equilibrium will unsustainable for them. However we can show the result p = MC in limit.

Sir, I just today discovered today your channel and it's such a gem. I am studying Economics in SXC Kolkata and will be graduating this year. How to access you? Do you teach professionally anywhere so as to get access to your classes?
Hi. Thanks you loved it! It's always a pleasure! I reside in Garia & I train students for PG Entrance Examination. Till this year it's online due to COVID. However, I will start offline training for entrances of 2023 in July 2022. I reside in Garia. I will share my WhatsApp here later. & please share the channel with your friends & juniors as well as seniors. To reach as much student as possible is my sole purpose.
Sir absolutely. Please do share.
Thanks a lot
Always happy to share.

I was following till you got to the determinant of the the J
I think that happened because I applied Implicit Function Theorem there by using Jacobian of the optimisation problem without stating the background theory. If this is the case, please confirm me. Currently, I don't have any class on Jacobian but I will definitely take one.
None of these books are available online
