For my ECON2011 class, I will provide you some videos for introducing some basic micro concepts, saving our lecture time. For the concepts that have been introduced in the videos, I will no longer repeat in class. Hence, it is important that you watch the video before our first class.
There are three videos. Each accompanies a lecture slide. They are all about demand-supply analysis, which would have been taught in any basic economics course (at high-school or university level) and should have been learned by students having some basic knowledge in economics. However, I've tried to add something new to my presentation so that not all contents students may have learned.
The first thing to notice is how you can get access to the video. You must follow the instructions carefully or you may not be able to watch it.
OK, now click to take the first step for getting access to the first videos.
STEP 1, please login via https://cuhk.zoom.us/ [If you are still in mainland China, you have to go to another Zoom portal usable in mainland.]
STEP 2, go to the following link and login with the passcode.
For Part 1: Click the link below for viewing:
Passcode: P39&Jx.Z
The lecture slide can be downloaded from this link. Notice that there is a typo in p.22. The correct statement should be 'When Qs>Qd, P will go down. When Qs<Qd, P will go up."
The second video is accompanied by another lecture slide. But there is a mistake there. Click and read the erratum first.
Erratum: The example given in p.13 of Demand and Supply Model 2 is incorrect. Please use the following example instead:
For example, P=30-2Q. The slope is ∆P/∆Q=-2 for all points.
At (Q,P)=(10,10), elasticity is -(10/10)/(-2) = 0.5.
At (Q,P)=(11,8), elasticity is -(8/11)/(-2) = 0.36.
Note that I will not correct the video and the slide for this part. Please simply take note of the above point.
The lecture slide can be downloaded from this link.
The video can be watched by the link below (do STEP 1 again if you have already logged out from Zoom):
Passcode: .^5UXrP1
The third video and lecture slide accomanying it can be viewed and downloaded. Click to open.
Do STEP 1 again if you have already logged out from Zoom.
STEP2: Click the link below for viewing:
Passcode: i2O0iG$K
The lecture slide can be downloaded from this link.
If you cannot view the videos, perhaps you read an instruction here before you click the Zoom links above again. For further difficulties, you should ask the ITSC section of CUHK. I am not a good technician who can solve your technical problems.
