An aside...people who write these types of articles display their economic ignorance when they fail to understand the difference between supply and demand curves and the QUANTITY demanded or QUANTITY supplied. My engineering economics prof in engineering school drilled that into our heads.

We must have had the same professor, or at least one from the same school of reasoning.

That’s good to hear! Few people know that difference. My Econ prof in my MBA program didn’t even know it! I explained it to him and he got it…as well as being impressed with my understanding!

Where does the author do that?

I don't see the exerpt above showing any confusion between changes in demand / supply, and changes in quantity demanded /quantity supplied. For example, he writes "Supply shocks on account of the lockdowns have further intensified price increases..."

This article is basically about Say's Law (a Macro topic).
