That is the new Allison Schraeger book, the subtitle is And Other Unexpected Places to Understand Risk, and here is one excerpt:
In many ways, the brothel is like any other workplace. There are weekly staff meetings (in a departure from the tradition at most companies, the women often wear outlandish hats and drink tea), access to financial advisers, performance bonuses, and even corporate housing…
But where Hof [the owner-manager] provided value was by reducing risk for both buyers and sellers of sex.
The top-earning woman at that brothel pulls in about $600,000 a year, and about half of that goes to Hof. And to audition for the brothel, women have to invest about $1500 in upfront costs (travel, clothing), with no guarantee of a job at the end of the process.
Here is an NPR interview with Allison.
