The price it charges for the drug varies greatly across different countries, as presented in the study by Barber et al. (2024). The study shows that the firm can still make a profit even if the price of this drug was set at a low price of say $10 per month, given that the costs of production for a pre-filled insulin pen are around $5 (max.).

Your task is to show what the profit of this firm might look like using a key economics diagram. To make graphing easier, we will consider the price of the Ozempic drug for the middle-income country Bangladesh, which is $38 (assumed the profit-maximising price). For this task, you will be required to illustrate and explain to a typical first-year undergrad student who has no economics background the profit the firm makes at $38 per month, and what has happened to profit (producer surplus), markup, consumer surplus and the output if the price was reduced from $38 to $10 per month. To help you construct the relevant diagram, here are some instructions and assumptions:

? You will hand draw one (1) diagram with an isoprofit curve, which is an adaptation of Figure 7.9d. An adaptation means that you modify the main diagram from the text to suit the case study at hand, for the drug used for diabetes and/or fight weight gain. Assume unit costs of production of this drug are a constant $5 per month.

? You are only required to draw one isoprofit curve at this profit-maximising price of $38 per month. Be accurate when you draw your isoprofit curve, but there is no need to calculate with precision every single point on the isoprofit curve. To show that your profit is the same ('iso'), calculate and show workings of what the (same) iso-profit would be for $50 and for $20.

? For the incremental quantities of drug production on the x-axis, use hypothetical values (rough guesses from your imagination). Also use your intuition for making up other prices/costs of the drug on the y-axis and make up a demand (straight-line) 'curve'.

? Finally, calculate and show workings for the change in producer surplus and markup, but you only need to shade in the change in consumer surplus if the price of the drug was set at $10 per month.
