Добавлен 19 янв 2010
A channel for learning Economics, Statistics, and Econometrics. I try to balance great intuition with in depth calculations and graphical interpretation wherever possible. The most frequent comment about BurkeyAcademy is: "Wow! This stuff really makes sense! I really can learn this!" Give it a try: These are the lessons I wish I had when I was learning economics. I use free software wherever possible (e.g., R, maxima, LibreOffice, Inkscape, Gimp, CamStudio, MapWindow...)
Sample Variance: Why the (n-1)? Understanding Bessel's Correction
This is NOT a proof of Bessel's correction. Instead, we explore several ideas to help you understand why the "n-1" makes sense. It boils down to the fact that we (usually) don't know the population mean when we are estimating the variance.

Real World Demand and Supply
Просмотров 1,5 тыс.Год назад
A discussion of how we can try to identify supply and demand curves in the "real world", by analyzing changes in equilibria and adding in other knowledge/data. What we discuss here gives a small hint of how econometrics can identify these equations. We also look at some data on the US milk market, using information about surpluses bought by the government to visualize supply and demand curves. ...

Juvenile Owl at the Disc Golf Course
Просмотров 3752 года назад
A crow has been harassing this Owl's nest for a couple of weeks now. It seems that the young Owl decided to make a run for it and flutter down to the ground. Not fully grown, but around the size of a basketball. Hopefully the little guy will be able to take flight in the next few days and have a better chance at survival. He is looking healthy so far.

THANK YOU FROM ITALY <3
Be great
So if you have 1-2 what are you gonna put for that? I’m still learning lottery math
this video is better than sitting in class at uni for 4 hours without gaining anything.
You have helped a lot sir . I stopped attending class , I was just watching you vedios from the start upto the end . Thank so much sir , because I got A+ in microeconomics ❤.
Dear Mr Burkey, is there a way to include non-spatially lagged variables in the slx model?
Are you asking "Can I include some variables with both lag and no-lag variables, but a few with only non-lagged?" If so, then yes, you can do this "by hand". There is a command that creates spatially lagged variables for you, and you can just add the lagged and non-lagged variables in a regular lm command using OLS.
it is more confusing
Just Perfect!
Thank you sir, How can i run SARAR - (Spatial AutoRegressive-AutoRegressive model) in Geoda?
I don't think you can in GeoDa. However, I can't be 100% sure because I don't really use GeoDa that much.
@@BurkeyAcademy Sir, Could you guide me on how can i do the SARAR (Spatial AutoRegressive-AutoRegressive model) Analysis. Nowadays I am trying to analysis SAR SEM SARAR model for my PhD research. Thank you sir.
Is Robin Hood index official or not used not major bodies such as imf??
I'm from Mexico and I cannot thank you enough for this videos! You are a great teacher and I'm learning more about economics than ever. Once again: Thank you!
Thank you so much for this!
Dear Dr Burkey, wondering. If I run LR.sarlm and it gives me a high p-value, am I *forced* to drop all the way down to OLS?
Bro you saved me ❤
Thank you so much for helping to understand spatial econometrics (and to handle my master thesis)! One question that came to my mind while watching you lectures. Why are the p-values different between the outputs of the SLX model and the Impacts function? In my dataset this leads to different levels of significance for the variables. It would be great to get an answer!
If they are different, you must be adding the "R=500" part of the impacts command, but you shouldn't include it since simulations are not necessary for SLX models. If you include the R=, it will run simulations for estimating the p values, but if you leave it out you will get the exact p-values.
I am using these videos to review for my Econ 101 exam and I have never enjoyed studying this much. The videos give you both practice and new tricks and explains concepts so well.
Truly amazed! A simple $1 on "The Lottery Network" resulted in a $900 gain.
I am wondering why I didnt find this when my semester started but atleast its in time for my review
Good thing the lottery would never cheat us out of a win!
Excellent video, thanks!

summary: what is economics (more detail) kita akan mempajari bagaimana berbagai orang dapat membuat pilihan, menggunakan sumberdaya dengan cara terbaik untuk memaksimalkan apapun tujuan mereka for society: sumberdaya kita adalah input alam, manusia, atau manufaktur yang langka yang digunakan untuk menghasilkan barang dan jasa. sumberdaya ekonomi ini terkadang disebut sebagai faktor produksi dan diklasifikasikan ke dalam empat kategori: 1. tanah (sesuatu yg berasal dari tanah), atau sumberdaya alam (pembayaran kepada tanah disebut "sewa") 2. tenaga kerja, atau waktu dan kemampuan orang-orang yang memproduksi barang dan jasa (upah) 3. modal, mesin, alat, dan peralatan yang digunakan untuk membuat barang dan jasa lainnya (bunga) karena saat anda memulai bisnis anda peu meminjam sejumlah uang untuk membeli bangunan,mesin berapa uang yang dipinjam dengan baik, itulah bunga anda even pake uang sendiri, kalau uangnya diambil dari bank atau investasi lainnya, u akan kehilangan bunga itu 4. kemampuan wirausaha, atau bakat manusia khusus individu yang menggabungkan faktor produksi lainnya. (pembayaran kepada wirausahawan disebut keuntungan) karena adanya kelangkaan, segala sesuatu memiliki biaya. ANDA HARUS mengorbankan sesuatu untuk mendapatkan sesuatu. mengambil suatu pilihan memiliki biaya peluang (opportunity cost): mengorbankan alternatif terbaik selanjutnya untuk pilihan yang diambil. metode ilmiah adalah proses yang digunakan untuk menemukan pengetahuan baru. ini melibatkan proses berikut: a. beberapa istilah digunakan dalam analisis ekonomi yang terkait dengan metode ini. 1. hipotesis adalah proposisi yang diuji dan digunakan untuk mengembangkan teori ekonomi. 2. teori ekonomi yang sangat diuji/dapat diandalkan disebut prinsip hukum ekonomi. teori, prinsip, dan hukum digunakan untuk memprediksi hasil kemungkinan dari suatu tindakan atau peristiwa. 3. model ekonomi dibuat ketika beberapa hukum atau prinsip ekonomi digunakan untuk menggambarkan kenyataan. contoh: penawaran dan permintaan, garis anggaran, kurva kemungkinan produksi b. ada beberapa aspek lain dari prinsip ekonomi. 1. setiap prinsip atau teori adalah generalisasi yang menunjukkan kecenderungan atau efek rata-rata. 2. asumsi hal-hal lain sama (ceteris paribus) membatasi pengaruh faktor lain saat memprediksi. 3. banyak model ekonomi dapat diilustrasikan secara grafis; adalah versi yang disederhanakan dari kenyataan ekonomi. 2. apa arti ceteris paribus? mengapa kita peduli? "ceteris paribus" adalah istilah latin yang berarti "semua hal lainnya tetap sama". ini digunakan dalam analisis ekonomi untuk menyederhanakan penjelasan tentang bagaimana satu variabel dapat mempengaruhi yang lain, dengan semua faktor lainnya tetap konstan. ini penting.
bagaimana individu membuat pilihan (choice): rational maximizers > individu membuat pilihan dengan mempertimbangkan biaya dan manfaat dari membuat pilihan. cost > benefit: dont do it benefit > cost: do it buat keputusan yg bisa membuatmu bahagia. kita tidak dapat memiliki segalanya dan kita tidak dapat melakukan segalanya
summary: what is economics ilmu ekonomi adalah ilmu sosial yang mempelajari bagaimana masyarakat membuat pilihan dalam rangka mengelola sumber daya nya yang relatif terbatas (langka) kelangkaan yang dibicarakan disini bukan (rare,valuable) tapi kelangkaan di ekonomi itu berbicara tentang keinginan individu yang tidak terbatas dan alat pemuas kebutuhannya yg terbatas sehingga individu ini harus membuat pilihan. ilmu ekonomi ada 2 bagian yaitu ekonomi mikro (mempelajari tingkah laku unit ekonomi secara individu > kita fokus pada pilihan > pilihan individu,perusahaan, dan bagainana pilihan pilihan kedua diatas bekerja sama untuk mempengaruhi apa yang terjadi dipasar) ekonomi makro: hasil keseluruhan pilihan pilihan dalam ekonomi mikro, bagaimana semuanya dijumlahkan. untuk menentukan apa yang terjadi dalam perekonomian, kapan pun anda berpikir tentang perekonomian negara anda berbicara tentang makro ekonomi.
These notes are very helpful.

Amazing 🤩
So effective, thank you. How can we do that in a semi-log presentation of data?
You made my day, instructor per excellence
Great video Plese can we have a video on how to compute expenditure function, hicksian function for CES utility function please
Thank you, professor, for this wonderful explanation Is this what is called bivariate moran's ?
No, this is how one variable correlates with itself in neighboring regions (univariate). I am not familiar with bivariate spatial correlation; at that point I'd be looking at spatial regression.
Many thanks Professor@@BurkeyAcademy
Excellent video. Would love a longer one going s bit deeper into reading the patterns. Thanks.
