Answer:
the marginal revenue product of baseball players is greater than the marginal revenue product of college professors.
Explanation:
Baseball players are responsible for a baseball teams' revenues, and they add up billions of dollars per year. For example, Max Scherzer sells jerseys, caps and other merchandise for millions of dollars, and his team winning the World Series this year increases the team's revenue greatly. Sometimes even without winning a championship some players still generate lots of revenue.
An individual's salary should be proportional to the revenue that they generate. Colleges have huge amounts of revenue, and college professors are responsible for a large portion of it.
The problem hear is that there are a lot of college professors and assistants, and the revenue must be split between many people. For example, Harvard University's revenue is about $5.5 billion per year, but it has over 16,000 employees (including about 2,400 professors).
