Prostitution and the internet

Scott Cunningham and Todd Kendall have two papers on prostitution, which discuss among other things how sex is sold on the internet:

“Prostitution, Technology and the Law: New Data and Directions” in Handbook on Family Law and Economics, Edward Elgar, Forthcoming 2010.

“Sex for Sale: Online Commerce in the World’s Oldest Profession in Crime Online: Correlates, Causes and Controls, ed. Tom Holt, Carolina Academic Press, Forthcoming 2010.

Along with sites that offer sex for sale, there's been a growth in sites that offer customer reviews. E.g. PunterNet, a site that reviews British prostitutes (but is on a California computer) became briefly famous when a British politician announced that she would ask California's governator to shut it down: Terminate degrading site - Harman "Harriet Harman says she has asked California governor Arnold Schwarzenegger to shut down a website containing reviews of prostitutes."

Here's a paper on wages as a function of age for a similar website for US 'escort' services: The Wages of Sin by Lena Edlund, Joseph Engelberg and Christopher A. Parsons

Alternatives to the NBA draft?

Scott Cunningham points me to this proposal to change the way professional basketball teams acquire new players. The present system rewards teams for poor performance by giving teams that lose lots of games a higher probability of very early draft choices. Early draft choices are important, because basketball is a game in which a single player can have a very big influence on team performance, and a small number of players are very good while still very young. So there may be an incentive, for a team having a poor season, to "tank" and try to be the worst team in order to have the highest probability of the first draft pick. The proposal would be to make draft choices independent of performance, and instead to alternate draft choices in a fixed schedule: The NBA's Possible Solution for Tanking: Good-bye to the Lottery, Hello to the Wheel

More on recommender systems for escorts

Scott Cunningham of Baylor writes:

"I saw today your post on the screening sites that prostitutes use ["Problem customer" registries for prostitutes]. I just wanted to pass along to you a paper I'm currently working on with Todd Kendall called "Prostitution 2.0: Estimating the Effect of the Internet on the Market for Commercial Sex in the US."
http://business.baylor.edu/scott_cunningham/Research_files/pro20-4.pdf
"We have been surveying online prostitutes for the last 10 months using data collected from The Erotic Review, which is a large "mall" that clients use to record detailed information about prostitutes in various cities. In the course of the surveys, we have been studying the way in which the Internet has facilitated improved screening, and even in some cases, signaling between clients and prostitutes. One of the more ingenious things that we have found is a case of signaling from clients to prostitutes wherein they send letters of recommendation to prostitutes, usually in the form of sending along information [from] another prostitute with whom they've already visited. This, we argue, has enabled prostitutes to update their beliefs that a new client is not a cop (or a violent client) because these letters are relatively more expensive for cops to send. A case in point - see this story about two police officers who were sleeping with prostitutes in Beaumont, Texas allegedly in order to make a case on a drug trafficker. When the public learned, the men were fired, and the officers are now suing the Beaumont, Texas police department for wrongful termination. (It's suggestive that indeed the private costs of using these kinds of methods are prohibitively high for cops, which we argue is evidence that the costs of signaling type to prostitutes is such that the separating equilibria and not the pooling equilibria is more likely to be happening). "

Here is The Erotic Review, and here is what they say about customers getting recommendations from escorts:

"TER White List
If you have a good reputation with the ladies, encourage them to visit the TER White List and submit a referral for you. The TER White List is an easy way for providers to give positive references about members they have seen. "

The market for hitmen

If two men who have just met discuss a contract killing in a bar, there's an excellent chance that at least one of them is employed in some branch of law enforcement. So you would think that a website offering to match buyers and sellers in this market wouldn't have a lot of customers, but it appears from some recent court cases that you are overestimating the sophistication of internet shoppers. Here's a recent story from the LA Times. Apparently the proprietor of the site wasn't content to act as a matchmaker, he tried to play both sides of the market by selling hits and then contacting the intended victims and offering to be bought off. But it appears that the demand side was real, and some of them are serving time too...

Website matches targets and hit man
"The case began with a website called HitmanForHire.net. The designer thought it was a joke, but the FBI and Irish police soon learned that Essam Ahmed Eid, a Las Vegas poker dealer, was in business."
************

In another twist, the domain name http://hitmanforhire.net/ has been acquired by someone who apparently hopes to make a movie about the case, and from the look of it thinks it might be a comedy:.

Australia legalizes medical use of psychedelics

 Scott Cunningham points out that Australia has become the first country to legalize the medical use of certain psychedelics. 

Here's the announcement from the Australian Government's Therapeutic Goods Administration (TGA)

Change to classification of psilocybin and MDMA to enable prescribing by authorised psychiatrists

"From 1 July this year, medicines containing the psychedelic substances psilocybin and MDMA (3,4-methylenedioxy-methamphetamine) can be prescribed by specifically authorised psychiatrists for the treatment of certain mental health conditions.

The Therapeutic Goods Administration (TGA) will permit the prescribing of MDMA for the treatment of post-traumatic stress disorder and psilocybin for treatment-resistant depression. These are the only conditions where there is currently sufficient evidence for potential benefits in certain patients.

Prescribing will be limited to psychiatrists, given their specialised qualifications and expertise to diagnose and treat patients with serious mental health conditions, with therapies that are not yet well established. To prescribe, psychiatrists will need to be approved under the Authorised Prescriber Scheme by the TGA following approval by a human research ethics committee. The Authorised Prescriber Scheme allows prescribing permissions to be granted under strict controls that ensure the safety of patients.

The decision acknowledges the current lack of options for patients with specific treatment-resistant mental illnesses. It means that psilocybin and MDMA can be used therapeutically in a controlled medical setting. However, patients may be vulnerable during psychedelic-assisted psychotherapy, requiring controls to protect these patients.

For these specific uses, psilocybin and MDMA will be listed as Schedule 8 (Controlled Drugs) medicines in the Poisons Standard. For all other uses, they will remain in Schedule 9 (Prohibited Substances) which largely restricts their supply to clinical trials."

*********

Scott shares a post by Shane Pennington on drugs that contrasts the Australian (medical) decision with the U.S. Drug Enforcement Agency's (legal) decision to maintain the ban on these drugs, despite the growing medical evidence (from U.S. studies, on which the Australian government relied) that psychedelics have some important medical uses.

"To support its decision, the TGA relied heavily on studies conducted in the U.S. and recent U.S. Food and Drug Administration (FDA) decisions recognizing psilocybin and MDMA’s extraordinary therapeutic potential. Around the same time, DEA shot down a petition—based on those same arguments and evidence—that Matt and I submitted on behalf of a palliative-care doctor, requesting rescheduling of psilocybin under U.S. law. The DEA’s four-sentence analysis completely ignored the same studies and FDA decisions that persuaded the Australian regulator to reschedule.  

"The dramatically different fates of these similar petitions reveal a troubling reality about U.S. drug law: Under DEA’s watch, the scientific and medical determinations of the nation’s leading public health agency carry considerable weight around the world but are often ignored at home. That revelation should terrify anyone interested in rational, evidence-driven drug policy. "

Colorado legalizes magic mushroom/psilocybin therapies

Venus of Willendorf, on OnlyFans

 The NY Times has the story:

OnlyFans May Be a Refuge for Nude Fine Art. The Vienna Tourist Board has joined the adults-only site to display artworks that other social platforms have censored.  By Valeriya Safronova

"OnlyFans has a surprising new member: the Vienna Tourist Board.

"No, its account will not feature after-hours photos of employees. Instead, the board will use the adults-only site to show images of paintings and sculptures displayed in the Austrian capital that have been blocked by social media sites for nudity or sexual content.

"The offending artworks include the Venus of Willendorf, a 25,000-year-old limestone figurine of a woman. Facebook removed a photo of it from the Vienna Museum of Natural History’s page several years ago for being “pornographic.”

...

"Vienna is hardly the only city whose art has been censored online. Many artworks, from all over the world, have been incorrectly identified by A.I. as pornography. Facebook has taken down pictures posted by the Museum of Fine Arts in Boston (of Imogen Cunningham’s photographs of nude bodies), the Philadelphia Museum of Art (of a painting by Evelyne Axell in which a woman is licking an ice cream cone) and the Metropolitan Museum of Art in New York (of a 1917 painting of a nude woman by Amedeo Modigliani).

Repugnance is hard to predict

Widespread repugnance, or its absence, is hard to predict.  Why do the U.S. and western Europe have almost opposite positions on the legality of surrogacy and prostitution for example? 

Here's a paper that carefully looked for, and failed to find evidence of a repugnance reaction from consumers about a scandal involving a company spokesperson (but unrelated to the company's business).

The Role of Repugnance in Markets: How the Jared Fogle Scandal Affected Patronage of Subway  by John Cawley, Julia Eddelbuettel, Scott Cunningham, Matthew D. Eisenberg, Alan D. Mathios & Rosemary J. Avery NBER WORKING PAPER 31782 DOI 10.3386/w31782  October 2023

Economics has long studied how consumers respond to the disclosure of information about firms. We study a case in which the disclosed information is unrelated to the product or firm leadership, but which could still potentially affect consumer patronage through the mechanism of repugnance, as described in Roth (2007). The information in this case concerns the arrest of Jared Fogle, the advertising pitchman for the Subway sandwich franchise, who was arrested in 2015 on charges of sex with a minor and child pornography. We study how the disclosure of this information, which was widely covered in the media, affected patronage of Subway. We estimate synthetic control models using data from a large nationwide survey of consumers regarding the restaurants they patronize. Despite the close and long-standing association of Jared Fogle with Subway, and heavy publicity of his crimes, we consistently fail to detect any effect of the Jared Fogle scandal on the probability of visiting a Subway restaurant. These results contrast with past studies of negative information disclosure, which tend to find negative impacts on sales, revenue, or stock price of the relevant companies. The absence of an effect in this case suggests that repugnance did not drive demand, and that consumers largely separated the offenses of a symbol of the firm from the products of the firm.

The Craigslist market for erotic/adult services

Scott Cunningham at Baylor, who is a serious student of illicit labor markets (e.g. the market for sex), writes

"Not sure if you saw this or not. Adult services censored on Craigslist

"It's not clear whether Craigslist has shut down the adult services section or not. That it is censored from the US but not from the rest of the country, though, suggests to some maybe.

"You've probably at least been peripherally aware that in the last month, approximately 20 state attorney generals had begun a new public campaign calling for Craigslist to shut down "adult services" altogether. FWIW, I have a chapter entitled "Sex for Sale: Online Commerce in the World's Oldest Profession" (with Todd Kendall) in the 2010 forthcoming book _Crime Online: Correlates, Causes and Controls_ edited by Tom Hold through Carolina Academic Press in which we explore, among other things, what happened the last time Craigslist implemented a major change to its erotic services section (namely, requiring all cities/markets to pay the $5-10 per ad and replacing erotic services with adult services, which was more heavily screened by Craigslist staff to identify prostitution advertisements). There was a temporary drop in ads, but they began to grow again as the weeks and months went on. But more importantly perhaps, there was a sudden spike in prostitution advertisements at a separate classified website operated by Village Voice called "backpage.com". Before Craigslist implemented that policy, backpage was never really used at all, but after that policy, it both saw a shortrun spike, and a longrun trend upwards in terms of daily posts, suggesting if nothing else that the cross-price elasticity of supply for these kinds of ads is not zero in the shortrun, but especially the longrun."

And here's the NY Times story: Craigslist Blocks Access to ‘Adult Services’ Pages, and two further stories that note that it will be easy for prostitution ads to relocate to other sites: How Censoring Craigslist Helps Pimps, Child Traffickers and Other Abusive Scumbags; and  Pimp Mobile--Craigslist shuts its "adult" section. Where will sex ads go now?  More recently, the "censored" label has been removed but the section remains closed: Craigslist Pulls ‘Censored’ Label From Sex Ads Area

Update (Sept. 15): ‘Adult Services’ Closed, Craigslist Says
"Craigslist, for the first time since it unexpectedly blocked sex ads from its site this month, said Wednesday that it had permanently closed its “adult services” section but defended its right to post sex-related ads as well as its efforts to fight sex trafficking.

"William Clinton Powell, director of customer relations and law enforcement relations at Craigslist, made the remarks Wednesday in testimony prepared for a hearing on sex trafficking of minors before the House Judiciary Committee.

“Craigslist has terminated its adult services section,” Mr. Powell said in his prepared remarks. “Those who formerly posted adult services ads on Craigslist will now advertise at countless other venues.”

Unraveling of NBA (and college) basketball

The NY Times Magazine writes about the Baylor freshman basketball player who is already an NBA draft prospect: Is it Dunk and Done for Perry Jones?

"In eighth grade, Jones was invited to attend a Baylor University basketball game on the campus in Waco, Tex. He was still a raw player, not widely known and in some ways perfect for the Baylor program, which was not attracting the best of the seasoned prospects.
...
"Jones declared on the ride home that he had found his school, and soon after, he committed to Baylor, meaning that the team’s coach, Scott Drew, offered him a scholarship and he accepted. It was only a verbal bond, one that could not be officially sealed until he reached his senior year of high school and signed an N.C.A.A. letter of intent, but he never wavered, even as coaches from more-traditional college-basketball powers, including Kansas and U.C.L.A., sent letters to his home.
...
"But just about everyone assumes that he will be a one-and-done player at Baylor, a pure rental who stays for a single season. That has become the norm for top college players. In fact, in some projections, as many as six of the top 10 picks in this spring’s N.B.A. draft are college freshmen."...
...(Players can no longer enter the N.B.A. straight out of high school, as Kobe Bryant, LeBron James and many others did.)
...
"You might assume that if Jones left school after just one season for the N.B.A., it would be a terrible disappointment to the coaches who recruited him when he was in his early teens — then had to keep in constant contact to make sure no one poached him. (Such vigilance is known as baby-sitting.) But that is not the case. If Jones leaves, it will further validate Baylor’s program and show everyone — the media, potential recruits, influential summer-league coaches who control players and sometimes broker them to colleges — that Baylor is a place that attracts top talent and produces N.B.A. millionaires. It will make it easier for Drew to recruit more players like Jones, who then, of course, also might also leave after one season. "

******
See my earlier posts Unraveling and uncertainty: The NBA draft, and Another step in the unraveling of the baskeball market about how the rule that players have to be 19 years old and a year out of high school before being drafted by the NBA has caused some players to play a year for European teams.
