In the early days of the COVID-19 pandemic, the demand for personal protective equipment (PPE) such as masks, gloves, aprons etc. was high. It was difficult for the supply of PPE to keep up with the demand and the PPE prices were skyrocketing.
From a manufacturer’s point of view, the PPE market was an attractive one at that time. This led new players to enter the PPE manufacturing business.
The higher number of PPE manufacturers caused the price of PPE to drop due to the increased supply.
The decreased price of PPE resulted in lower profits for the manufacturers.
Lower profits reduced the attractiveness of the PPE market, inducing manufacturers to pull out.

Draw a causal loop diagram (CLD) that describes the aforementioned situation. For that, you need to define the variables, the causal links between them and the sign of the links.
Explain all elements of the CLD. Assign the correct loop polarity to the feedback loop of the CLD that you designed and explain how you came up with that. Provide examples of how a change in some variable propagates around the loop. What is the dynamic behavior of the system based on its structure (i.e., the CLD you designed)? For example, how will the PPE price vary with time?
