Brown’s Most Expensive Books

  • What's the most expensive required textbook at Brown?
  • What's the most expensive class?
  • What's the most expensive department?

Methodology

To answer these questions, we'll mine data from Courses@Brown (Brown's course-enrollment portal). Crucially, for each course, this portal reports:

So as to not succumb to sensationalism, we'll only consider the minimum price of required textbooks (unless otherwise noted).

Even so, given the eye-popping expenses that will follow, it's probably false to believe that all students purchase the required textbooks, or that they pay Brown Bookstore's prices for them.

Most Expensive Books

The $264.50 Investments, by Bodie, Kane & Marcus tops out as the most expensive required textbook of Fall 2020.

Gross Domestic Department Product

The above ranking of most-expensive courses is dominated by popular classes such as Investments and Foundations of Mechanics. In these cases, it is not merely that the course's required textbooks are expensive, but that many students are subject to purchasing those expensive books! So, let's ditch our previous individual perspective and instead try to estimate the gross domestic product of Brown's courses and departments.

Course GDP

We'll estimate the "GDP" of a course as its enrollment multiplied by the total cost of its required textbooks.

With a staggering GDP of $82,325.00, CHEM0360 Organic Chemistry trounces all competition. The top-25 courses with the highest GDP follow:

Department GDP

Next, we'll estimate the "GDP" of a department as the combined GDP of its courses.

Once again, ECON astounds: if all Fall 2020 economics enrollees purchased their required textbooks at Brown Bookstore's minimum price, together they'd spend $174,861.60! The top-20 departments by GDP are as follows:

University Textbook GDP

Finally, we'll estimate the university's textbook GDP as the combined GDP of its departments: $1,268,445.51 in Fall 2020!


Postscript

As this was just an afternoon project, I haven't meaningfully checked any of these figures—so please don't treat them as authoritative! Rather, if you are interested in diving deeper, please reach out! I'm happy to share my underlying data.
