here). Both industries have outlying margins (around 20%) and also outlying settlements with governments for violating marketing and other business-related laws (see chart on left).
In November, 2014, BBC reported that in 2013, US giant Pfizer, the world's largest drug company by pharmaceutical revenue, made an "eye-watering 42% profit margin."
The BBC article also included a table showing the total revenue, R&D spend, Sales and marketing spend, Profit, and Profit margin of the top 10 pharma companies.
The evidence shows that many drug companies spend far more on marketing drugs - in some cases twice as much - than on developing them. It's deja vu all over again in the ongoing debate of R&D spending vs. promotional spending. See a critique of the numbers here.
In any case, I was more interested in seeing if there was a positive correlation between pharma profits and marketing and/or research and development spending. So I prepared the following chart from the data.
In this chart, the companies are arranged with the highest profits ($bn) on top and the lowest on the bottom.
I'm thinking there is a better correlation between marketing spend and profits than between R&D spend and profits. What do you think?
