Shortly after Divoc moves to non-linear pricing, the regulator notices a sharp spike in the average price paid for a unit of the vaccine. The regu. lator, who cares only about consumer surplus, suspects that Divoc's ability to price discriminate is harming consumers. To combat this, the regulator proposes two pricing! restrictions The first such restriction prohibits Divoc from explicitly charging a different price to different pharmacy types. In other words, it cannot use the identify of a pharmacy to set the price. Otherwise, Divoc is free to price as it pleases. If this policy goes into effect, how many vaccines will be sold? (Hint: Assume all pricing schemes are still available to Divoc, only now it is restricted in the information it can use to price.) a) 175,000 units
b) 130,000 units
c) 90,000 units
d) 230,000 units
e) 330,000 units
f) 270,000 units

Employees at a library check out books to patrons. books have an isbn and a name. the library sometimes has multiple copies of the same book. books have one or more authors. a patron is an individual who has an active (non-expired) library card. for each library card, we store the person's first and last names and their address. for each employee, we store their employee id, current salary, first and last name and their address. we also store the employee id of their current manager. each time we check out a book to a patron we need to store the date of the transaction, the employee who checked out the book to the patron, and the library card of the patron. some employees have library cards. if an employee patron turns in a book late, the fine that they pay is a percentage of their salary. some employees are authors who have library cards—they are allowed to check out as many books as they like.
