Economics tutorial videos from my courses at the University of North Carolina at Charlotte (2024- ), the University of South Dakota (2018-2024), and Indiana University (2016-2018).
Videos are range from introductory undergraduate to advanced undergraduate and MBA-level courses.
I hold a Ph.D. in economics from Purdue University and currently teach at UNC Charlotte's Belk College of Business.

Simple Regressions in Stata (including regress, scalars, and scatter plots)
In this video, we will cover how to run a simple regression in Stata. I also show how to verify the calculation using the equations derived from the moment conditions. We learn to save values as scalars in doing these calculations. Finally, I show how to create a scatter plot with a regression line overlaid.

thank you, finally understood how it works exactly
Thank you, Sebastian, this is so helpful and you made it easy
The final answer for the 5th Rule is confusing. 2x square x 6x = 12 but why on the other side didn't you use the power rule but only multiplied 3x by 2?
Please can you tell the managerial edition you’re using?
Thanks
THANK YOU🙏🏼 This video has been extremely helpful
Hello, i would like to know if its necessary to use vce(robust) when using within estimator, i mean xtreg...fe, vce(robust)
this is so helpful! thank you!! you made it so easy to understand!

i need help
complete the series...do different utility functions.
Is there an introduction video that explains basic use of derivatives?I'm totally lost.
Motherfucker! Why don't you use common files? You madafakas always make it hard for us general people.
Bitch! I spent 6 hours to get data. Khanki magi

Hi I have a string of numbers but it's red. So I use this command to encode but all my numbers have been changed to others. I dont know why, pls help me 😭 🙏🙏🙏
The command you probably need is "destring." Most likely what happened is that you have at least one value that is not a number, which is why Stata read it as a string. You first need to make sure all the values are valid numbers, then use destring to generate a numerical version of your variable.
@@sebastianwaiecon thank u, I can fix it now <3
How to check colleration for categorical variables

When will we conclude there is heteroscedaticity? When p is above or below what value?
if p is less than 0.05 then heteroskedasticity else homoskedasticity
Greetings In case of dummy variables are used as control variable if they come out to be significant what does it mean?
👍👍
Why does SL has the absolute advantage
thanks man i was struggling from many hour this video was a life saver for Me.
hi. i need help
U're amazing man i hope you know that !
Excellent! Thank you for saving me tons of time :)
Thank you from vietnam
I like your videos on the managerial economics courses. However, I never learned or was exposed to calculus or the functions of derivatives and partial derivatives. I can follow the steps in your videos, but not grasping the wisdom found in each function. I felt it necessary to drop out of a managerial economics course because of this issue. I can get through most of the economic principles on markets and structures, but the math is a problem. Please advise what steps to take to master the math found in this course. I am a young 65 plus adult studying to get an MBA.
Hello Sebastian. Thank you for the video, but how do we do things manually if we have two endogenous variables.
Thanks you saved my ass
hi thanks for your video, what if the package is not found what we do in this situation
Thank you a lot
this is amazing, you save my ass
Hi, when I try to perform panel regression using fixed effect on STATA with dummy variables, STATA "Omit" my variable in the result. It shows "omitted". How can I avoid that?

amazing!!
Each time I'm running as effects= "twoways", I'm getting an error message as 'Error in solve.default(crossprod(WX, t.CP.WX.A1)) : system is computationally singular: reciprocal condition number = 1.12264e-21'... Can you please shed some light?

Hi! This video is soooo helpful thank you so much. I just do not get Why the derivative of 2x is just 2 and not d2/dx? In minute 5:28 at rule 5. Thank you so much
Check rule no. 2 and you'd get it.
Thank you very very much
this was awesome thank you very much for posting this
Boring
Hello, I am having trouble in the question. Could you please help me explain how I can solve it? I really appreciate that . Thank you so much . Question is: "Pulp and paper mill is producing polluting which can quantified as MEC=0.6Q. Production is identified as -4+3P, Consumption is identified as 10-2P. When the externality is accounted for what will be the quantity produced?"
Thanks. Please can you show. What should be the minimum observation required FOR DID
Bare minimum, 4 observations to make the math work, but otherwise no minimum. More observations will provide more statistical power. See my video on difference in differences estimation.
Your email contact kindly
So good
Dear Sebastian, this is so helpful!! I have one question, I want to include in my table se r2 and t-statistics. How would the code work like ?? Thank you so much. RENE
There is a link to the estout manual in the video description - it's all there.
