This morning Dr. Ashish Jha responded to a reporter’s question making the crucial — and too often neglected — distinction between demand-driven or supply-driven disequilibria. In terms of strategic — and responsive — potential actions, this is a crucial differential diagnosis. Below I have teed-up the full four minute interview. The push-pull distinction begins about the 1:55 mark. Dr. Jha’s explanation is accurate in response to the specific products the reporter references. This has also been a recurring feature of so-called supply chain “shortages” for a wide array of products over the last three years.
