1 hour before the exam this dude saved my ass! thanks buddy
2hrs before mine atp😂😂
Really helpful, I liked your simple way of explaining it. Thank You!
Thank you Justin for saving me again
7:15 How is (0.25x0.20)-(0. 10x0.1 5)=0.585???
My result shows 0.035
am wondering too about the figures
I'm also trying to figure that one
@@emiliathomas1802 it's because you have to look for the cofactor matrix of the leontief matrix (this is the I-A matrix), not A as demonstrated in the video
@santari thanks alot now it makes sense
you did it!
Thank you sir 🙏
I haven't words which I thanks by you!
its made clear. just the last, the question says the demands have increased by 40 and 70 respectively. the new output demand is not supposed to be 40 and 70 but the original demand minus the change. like industry 1 will be 400+40=440, industry 2, 100+70=170 and industry 3 1500-100=1400. correct me if I am rwong
but overall this is one of the few videos that explained all the steps of an input output model. please make one for a bordered hessian again with all the steps
Bien, utiliza la inversa de la matriz de Leontief directamente , luego la adjunta traspuesta y el ya le cambio de signo, para luego multiplicar vector por vector y obtener la nueva respuesta de los nuevos X1, X2,X3.
Your the best but kindly at finding the cofactor you have mislead most of us
Amazing Video, thank you!
Pls help me...
In the Leontief input-output model, how do I find the following:
1. impact multipliers
2. Intra and inter-sector effects
nice lecture
at 14.0 do you mind explaining how you are getting o.7?
I will appreciate
its 1-0.30. 0.30 is the total for industry 1
Same got lost there
(d) part says that demand increases or decreases by (not to) therefore we should increase d1 by 40 i.e 400+40= 440
in number 3 where do you get 0.70 ; 0.45 ; 0.60?
hope you reply to my question
thank you
why the primary must 0.70?
The columns stands for the inputs.So O. 70 , 0.45, 0.60 comes by adding the columns of matrix (I-A)
I'd really love to see this in R!
Great vids, keep up the good work

Please where did u get the 0.70 and 0.45 that's the number 3
Thanks☺
thank u too sir, God blesssssssssssssssssssss u
Approach is perfect yet answers are full of mistakes. I would advise you dont compare your answers to his. The first co-factor was wrong and also when he was finding the inverse, instead of a determinant of 0.4773 he used 0.4733 which has make all his solutions wrong but one a correct method working with wrong figures
Thanks for saving my time

Solve that's for meConsider a Leontief input-output model with no substitution. Assuming that the input matrix is given by .
Prove that this production plan is efficient. [6 Marks]
Show that any production plan with is a profit maximizing at a unique vector of prices. [8 Marks]
Show that the prices obtained in (b) have the interpretation of the amounts of the primary factor directly or indirectly embodied in the production of one unit of the different goods. [11 Marks]
good
Primary input 0.70 how is it come?
are you stupid
Pano nakuha Yung sa inverse na answer e.g. 1.2256 and so on. Dito ako nalilito....
Sana may make answer....
Idivide mo bawat entry with the determinant which is 0.4773. So for a11 or entry 0.585, it will be 0.585/0.4773 = 1.2256.
Y/a= 1-A
