This channel contains videos for my courses at Copenhagen Business School
Political Economy of Trade Policy
This video is made for the CBS Law class Regulation and International Markets. I discuss three topics: median voter/collective action as explanations of trade policy, trade wars, and regional trade agreements.

This video is for my upcoming Regulation and International Markets course in the law department. I explain the idea of the invisible hand through an allegory with two baristas.
Proof that there are more real number than integers

Classic proof that there are more real numbers between zero and one than integers. I have a star on my face because my son got a bunch of fake tattoos and had some fun applying them to me.

Amazing video that saved my life 😂
i love you
Sir please tell me main difference between solow and rck model in economics and how they implement in real world economy
Very helpful
I’d be interested to hear your thoughts on this as it relates to the AI boom happening now
1. How a certain economy reaches to equilibrium in the Solow model. Substantiate your answers with graph and mathematical verification
Thank you for all of these videos. You explain things more clearly than my lecturer.
Thank you!
Hello Dr. Jenkins. Is it possible for us to get a copy of the lecture note? How can we contact you?
00:03 Overlapping Generations Model critiques the assumption of infinite growth 02:26 The OLG model challenges traditional thinking about future generations' welfare. 07:07 Population lives in two periods, young and old. 09:32 Workers save based on rate of return and wages 15:03 Workers loan capital to firms and consume it in period 2. 17:23 Solving the worker's problem intuitively and formally 23:01 Euler equation relates consumption in period two to period one 25:56 Consumption in period two depends on the rate of return on capital or the rental rate of capital in period t+1. 30:52 C1T definition with notations 34:11 High returns on savings impact present consumption. 38:33 Understanding the dynamics of capital in the economy 40:58 Labor and capital replacements in OLG model 45:52 Cobb-Douglas production technology simplifies relationship between capital and output. 48:14 The OLG model involves reflecting points and analyzing equilibriums. 53:38 Wages and saving behavior determine the capital level 56:22 Considering the welfare of present and future generations 1:01:09 Economics models may not accurately reflect real-world preferences. 1:03:21 Economic models make strong assumptions about people's preferences. 1:08:48 Forcing people to save more leads to lower consumption in both young and old age. 1:11:03 By adjusting the level of savings, we maximize overall lifetime consumption. 1:15:42 Population decrease affects capital growth 1:17:56 Government's role in forcing people to save less rather than more.

Is Lt supposed to labour and not population?
At 32;16 you say that the only input factors that enters the fi al good production function are the intermediate goods; So you nean to say that labour is not used by firns in tbe final sector? Then yiu say that labour is the only input used by firms i. The intermediate sector? Nothing is produced in the intermediate sector. It is a arket point where R&D and final sectors meet for exchange. R and D sector selks patents ti final sector. Lavour is used i. R and D and final sectors only! Correct me if I am wrong
oiii you friggin legend
thank you David, saved me with this!
I wonder in no-ponzi condition why we use "s to infinity" instead of "t to infinity"
Hi david, is it possible to get the slides for Ramsey model?
Can you give me some reference book for this topic. And also new classical and new keynesians
Thank you so so soooooo so much, I don't know how I would pass this semestre without you! I wish my professor was like you, thank you for giving me hope. Hugs from Chile
at this point: I'm lost
Greetings from Perú, thanks for this lesson.
Good morning friend, would you provide me in Word with the development of that Economic Model of the teacher? Nordhaus
Professor how can I add more equations?
I am really interested to do a paper about DSGE model in my country, but STATA does not work, I want to ask if I can use R package
You can use statistical software, but I would suggest using a more general purpose programing language like python. Usually you have to program up and solve a few equations. If you have access to it, many macroeconomists use dynare for solving and simulating DSGEs.
@@veryshuai thank you so much for your interesting comment
Some points need covering; 1) Are the Romer production functions (final goods & intermediate goods) exhibit constant returns or increasing returns to scale 2) The scale effect of big population and hence big pool of talent needs qualification given the decline in US productivity growth and its absolute size of talent (see Charles Jones' comment) Comments please?
i don't understand 1 thing, why is not optimal to choose D? if i have no consumption i should be happy no? what i miss? why don't have comptuntion is bad?
Excellent video, thanks! Helped me a lot. I saw that you got a couple of papers under revision at the JPE and REStud, hope you publish those!
Why c(t) is C(t)/A(t) and w(t) is W(t)/A(t) , but k(s) is K(s)/A(s)L(s) ?
How can I compare capital not capital per worker?
I am pursuing MA Economics with specialisation in trade and finance from Indian Institute of Foreign Trade , New Delhi, India. I watched your videos on UA-cam on Growth models while preparing for my macro mid sem exams and I must say that you are doing an absolutely incredible job. It's unparalleled the way you describe the economic logics behind those equations. It's really hard to make people smile while doing macro derivations but you are absolutely adept at it . So , here's a big heartfelt thank you from India.
The music took away all the good things about the video. Thank you though
Hello Mr. Jinkins, is it possible to ask you a macroeconomics related question? If so, how can I reach out to you? Thank you in advance
Why not ask here? Can't promise I'll promptly respond.
@@davidjinkins8293 it's concerning a question on a problem set. I'm struggling with an equation and I've no one to look over it. If you could help me out that'd be much appreciated
Good
niceee
ure a blessing
thanks you so much
For the frst time I understood ths model to some extent. Thnks skipper😊
Hello sir do you have video on Investment from David romer book ?
excellent sir thank you very much
The second line is a bit confusing. If we multiply and divide by A(t) why is the initial wealth term A(0) L(0) / H. Should it just be A(0)/H?
Amazing, absolutely amazing
Thank you so much for this video, you're amazing!!
It would be great if you also define the equation -- for instance what G and G bar represent.
I wish you were my lecturer
What is the title of Romer's textbook? Thanks
Advanced Macroeconomics, David Romer. You probably want to get the 5th edition.
' Can you give us a link to the slides to make notes on?
I am so grateful for you
sorry but this is not a good explanation
haha u dont get it
So this series soooooo much! Thank you for sharing those lectures with us!!!!!!
