The labor market for OnlyFans chatters

 Here's a story by a professional writer and journalist, who appears to be a middle-aged dad, about his efforts to find and then master a job impersonating a 20-something female sex performer chatting with her fans on the website OnlyFans.

Wired has the story:

.I Went Undercover as a Secret OnlyFans Chatter. It Wasn’t Pretty. Your online influencer girlfriend is actually a rotating cast of low-wage workers. I became one of them. by BRENDAN I. KOERNER

"Like many of OnlyFans’ top earners, she had hired a management agency to help keep up with her customers’ demands for personal attention. “The chat specialists they give you, that was a huge deal for me,” she said. The agency provided a team of contractors whose sole job is to masquerade as the creator while swapping DMs with her subscribers. These textual conversations are meant to be the main way that OnlyFans users can interact with the models they adore.

"The existence of professional OnlyFans chatters wouldn’t have surprised me so much if I’d given just a few moments’ thought to the mathematical realities of the platform. OnlyFans has thrived by promising its reported 190 million users that they can have direct access to an estimated 2.1 million creators. It’s impossible for even a modestly popular creator to cope with the avalanche of messages they receive each day. The $5.6 billion industry has solved this logistical conundrum by entrusting its chat duties to a hidden proletariat, a mass of freelancers who sustain the illusion that OnlyFans’ creators are always eager to engage—sexually and otherwise—with paying customers.

...

"Gradually I realized that my best shot at understanding how chatters operate would be to join their ranks. As an English major who’s been fortunate enough to make a living with words for more than 20 years, I naively assumed I was qualified to land a gig. And as a writer, I was curious to learn what kind of artistry the job would require—what it takes to ensure that OnlyFans users never doubt they’re really interacting with the objects of their desire.

"AS I EMBARKED on my job hunt, I asked the owner of a top-tier OnlyFans agency for tips on how to make myself an appealing candidate. He was pessimistic about my odds of getting hired, mainly because I’m American. He said agencies tend to favor contractors who reside in lower-wage countries. That insight was borne out as I poked around the online communities where chatters find help-wanted ads; though the vast majority of OnlyFans users live in the US, the bulk of my competitors were based in places like the Philippines and Venezuela. Judging by their posts on the r/OnlyFansChatter subreddit and in an invite-only Facebook group, these workers are relatively well-educated, with university-level English and ace typing skills that some developed in high-pressure call centers. They also put up with all manner of abuses: OnlyFans agencies are notorious for stiffing their freelancers, forcing them to work 70-hour weeks, and summarily firing them if they miss a shift due to a power outage."

Teaching online: Singapore, NYC react to Zoombombing of online classes

Some of us are old enough to remember when email didn't come with security concerns.  Things are moving faster these days, so it's no surprise that there are Zoom trolls and scammers.  Singapore and NYC schools have decided not to use Zoom to conduct their online classes any more.

Here's the Singapore story from the Guardian:

Singapore bans teachers using Zoom after hackers post obscene images on screens
‘Very serious incidents’ have forced suspension from online schools as conferencing app faces renewed questions over security

"Singapore has suspended the use of video-conferencing tool Zoom by teachers after “very serious incidents” in the first week of a coronavirus lockdown that has seen schools move to home-based learning.

"One incident involved obscene images appearing on screens and male strangers making lewd comments during the streaming of a geography lesson with teenage girls, media reports said."
**********
Here's the NYC story from CNN:

New York City schools won't be using Zoom anymore because of security concerns
By Nicole Chavez and Sarah Jorgensen

"Schools in New York City are moving away from using the video conference app Zoom after a review of security concerns.
...
"The department does not have a central contract with Zoom, Filson said, and students and staff will be transitioning to Microsoft Teams, which has "the same capabilities with appropriate security measures in place."

"Earlier this week, federal officials began warning of a new potential privacy and security concern called "Zoombombing."
...
"Eric Yuan, the founder and CEO of Zoom, apologized to the video conferencing app's users for the privacy issues earlier this week, saying his team will stop adding new features for the next 90 days and instead focus solely on addressing privacy issues.
...
"Yuan said over 90,000 schools across 20 countries have been using the platform for online teaching since the company offered its services free of charge to schools because of the Covid-19 pandemic."

Signaling and matching in an online labor market, by Horton and Johari

Here's a paper on signaling and matching in a prominent but un-named online labor market that is readily identifiable.

Engineering a Separating Equilibrium

John J. Horton and Ramesh Johari
August 14, 2018

Abstract: This  paper  explores  whether  platform-created  signaling opportunities can move designed markets to more desirable equilibria.  In a large on-line  labor  market,  buyers  were  given  the  opportunity  to  signal  their relative  preferences  over  price  and  quality.   The  intervention  caused substantial sorting by sellers to buyers of the right “type.”  However, sellers clearly tailored their bids to the type of buyer they faced, bidding up against sellers with a high revealed willingness to pay.  Despite this “markup,” a separating equilibrium was sustained over time, suggesting buyers found revelation incentive compatible.  We find evidence that informative signaling improved matching efficiency and match quality.

"The signaling opportunity was simple:  when posting a job opening,  employers selected one of three “tiers” to describe the kinds of applicants they were most interested in:  (1) Entry level:  “I am looking for [workers] with the lowest rates.”;  (2) Intermediate:  “I am looking for a mix of experience and value.”; (3) Expert:  “I am willing to pay higher rates for the most experienced [workers].”  We refer to these tiers as “low,” “medium,” and “high,” respectively.   When  the  signaling  opportunity  was  introduced  market-wide  (which occurred after an experimental period), the tier choice was revealed publicly to all job-seeking workers."

Safe exchange zones

Marketplaces aren't just tools to bring potential transactors together, they can also seek to make transactions (physically) safe.  Criminals can lurk among Craigslist buyers and sellers, and so there's been a growth of "safe exchange zones".


See e.g. this recent story from New Jersey, where the police department set up a safe exchange zone following a robbery/murder:
"Passaic Mayor Hector Lora says that his town installed the zones inside and outside of the police station after a series of robberies and scams related to online sales.

“The biggest difference that it makes is that it provides a safe area for individuals to make these transactions and be able to make it back home,” Lora says.

“We have 24 hour surveillance, 24 hour staffing, and it's round the clock,” says Deputy Chief Christopher Storzillo.

"Lora says that he hopes that other towns follow suit and add their own safe exchange zones.

"But until other towns have these zones, officials urge anyone who is buying or selling items online to meet in a public, well-lit place and to call authorities if anything seems suspicious."
**************

It turns out that safe exchange zones are a thing, here are some databases to help locate one near you:

More Backpage (.com) news


From the Washington Post:
Backpage CEO Carl Ferrer pleads guilty in three states, agrees to testify against other website officials
"Carl Ferrer, the chief executive of Backpage.com whose name was conspicuously absent from an indictment of seven other Backpage officials unsealed Monday, has pleaded guilty in state courts in California and Texas and federal court in Arizona to charges of money laundering and conspiracy to facilitate prostitution. In addition, he agreed to testify against the men who co-founded Backpage with him, Michael Lacey and James Larkin, who remained in jail Thursday in Arizona on facilitating prostitution charges.
Backpage, in addition to hosting thinly veiled ads for prostitution since 2004, was accused of hosting child sex trafficking ads on its site and even assisting advertisers in wording their copy so they didn’t overtly declare that sex was for sale, federal investigators allege. In a remarkable three-paragraph admission in his federal plea agreement, Ferrer wrote that “I conspired with other Backpage principals … to find ways to knowingly facilitate the state-law prostitution crimes being committed by Backpage’s customers.
...
"Ferrer’s sudden capitulation launched a wild seven days for Backpage. A day after Ferrer’s first secret plea, the federal government arrested seven of Ferrer’s former colleagues, including Lacey and Larkin, and shut down Backpage’s websites in the U.S. and around the world. ...
"Then on Wednesday, President Trump signed into law “FOSTA,” the Fight Online Sex Trafficking Act, a bill inspired by the stories of children being prostituted on Backpage..."
**********************
And here's a story from Quartz that follows the work of economists researching the (not all bad) effects of internet marketplaces for prostitution.

Online anonymity, bitcoin, illegal drug markets, and traditional law enforcement

If you were a Silk Road customer, you'll have to find another online drug market: F.B.I. Seizes Silk Road, an Online Drug Market, and Makes Arrest. But it sounds like while the organizer was arrested (after soliciting a murder for hire) the anonymity of transactions may have allowed many of the customers to escape detection.


"The Silk Road marketplace is available through Tor, a popular tool for maintaining anonymity online. Bitcoin, a virtual currency, is used for transactions. The identities of sellers are not known to the buyers. About $1.2 million in sales were conducted a month in early 2012, according to a study by an assistant professor at Carnegie Mellon University, Nicolas Christin.

"As part of the investigation into Silk Road, authorities said, they seized 26,000 bitcoins worth $3.6 million.

"The arrest is part of the latest push by federal authorities to police the anonymous marketplaces that have flourished as a result of virtual currencies and software meant to help users browse the Web anonymously. In recent months, federal authorities charged seven people believed to be linked to Liberty Reserve, another virtual currency, which prosecutors described as a $6 billion money-laundering operation that facilitated a black market for everything from stolen identities to child pornography.

"One recent study found that a broad range of drugs, including ecstasy, LSD and heroin, were available on Silk Road, but that marijuana was the most popular item offered for sale. Books and erotica are also sold.

The online market for tailors

One of the markets that the internet seems likely to change profoundly is the market for custom clothing. Bloomberg news had a recent report on what looks like it could be a small beginning of a big thing:

"Custom clothing startups J. Hilburn Inc., American Giant andBonobos Inc. are racing to gain share in a U.S. e-commerce market that Forrester Research Inc. estimates will reach $327 billion in 2016, up from $202 billion last year. They’ve won customers and venture backers by cutting stores from the supply chain to ship straight to consumers from the factory, charging lower prices than department stores and eking out higher margins than Amazon.com Inc. , the biggest Web retailer.

“J. Hilburn will sell shirts that are made out of the same fabric mill in Italy that a Zegna would sell at Neiman Marcus for $300,” said Brian O’Malley, a partner at Battery Ventures, an investor in the startup, which has raised a total of about $12 million. “They can sell that same shirt totally custom-made for the customer for less, and do that still with healthy margins because there are a lot less middlemen along the way who need to get paid.”

Auction design within online games

This looks worth following up on...Michael Giberson reports Poor market design causing high prices in Diablo III auction house?

http://arstechnica.com/gaming/2012/06/real-money-auctions-launch-in-diablo-iii/


Why Diablo 3's Real Money Auction House Should Not Be Your Summer Job
"For years, illegal black market sellers have been hawking virtual gear for real life money to great success. There was little point attempting to combat such practices, as little or nothing could be done to stop them, so Blizzard had an alternative idea they wanted to try with Diablo 3. A legal auction house using real world cash, where they got a piece of the action.
"There’s been an in-game gold Auction House in operation since the launch of Diablo 3, but yesterday marked the first time the Real Money Auction House went live, after a few weeks of delays."

Online labor markets

John Horton, who has an online labor blog, has compiled a great list of online labor markets. Here's what it looked like when I recently checked:

Resources

Major General / Programming Sites

  • oDesk is a rapidly growing site that encourages buyers to offer work on hourly terms. The site provides very robust monitoring tools: workers download software that tracks the time that they spend working on projects. The software also logs workers' keystrokes and even periodically takes screenshots of their screens. Because this monitoring allows buyers to observe workers so closely. Workers are guaranteed payment for their hourly work. 
  • Guru.com allows buyers to post jobs and solicit bids from workers. 
  • Elance is probably the largest and most well-known general site. The main work categories are Web & Programming, Design & Multimedia, Writing & Translation, Administration Support, Sales & Marketing, Finance & Management, Engineering & Manufacturing and Legal. 
  • rentAcoder.com focuses on computer programming. Programmers work on a strictly fixed-price basis. After a project is awarded to a bidder, the buyer places the agreed upon amount in an escrow account. Payment is not released until the buyer approves the work. If there are disputes, the company provides arbitrators.
  • Freelancer.com 
  • iFreelance is a general site with the same basic model as Guru, oDesk and Elance. Very little data is available without registering with the site.
  • ScriptLance
  • Solvate - TBD 
  • Hypios - TBD

Software Testing

  • uTest provides software testing using a pool of workers who are paid to find bugs. Buyers (software companies) seek testers with certain demographic characteristics, including software sophistication and the platforms used. uTest selects matches from its pool of registered testers. The testers report bugs and make suggestions and are paid for verified bugs and helpful reviews.

Design

  • 99 Designs allows buyers to sponsor design contests, usually for logos or specialty events. The buyer states a price that they will pay for the winning design and a date when they will choose the winner. Workers then submit designs as small, thumbnail images which the entire community can view and vote on (these votes are not in any way binding). One interesting feature of this market is that it is one of the few real-life examples of non-political all-pay auctions. As of January 2009, the community had 25,100 registered designers who submitted 1,152,786 designs for 15,993 contests and received $3,465,314 in prizes.
  • CreateMyTattoo.com is just like 99 Designs, but for tattoos.
  • CrowdSPRING
  • iStockPhoto is a royalty-free photo exchange that allows photographers to upload images and sell them to individual buyers. Over 50,000 photographers have contributed over 4 million photos.

Advice & Search

  • BitWine provides a network of freelance advisors who charge clients a per-minute rate for consultations. Advisors are ostensible experts in some field, such as nutrition, travel, coaching, technology, etc. Consultations occur over the voice-over-IP (VoIP) technology Skype and payments are made through PayPal. BitWine takes a percentage of transactions fees.
  • InnoCentive
  • ChaCha

Advertising

Micro-Tasks

  • Amazon's Mechanical Turk is unique in allowing workers to perform simple, piece-rate tasks like captioning writing captions for photographs, extracting information from scanned documents and transcribing audio clips for money or store credit. Unlike other sites, workers may begin a task as soon as it is posted, and the buyer reserves the right to accept or reject work.
  • LiveWork
  • Short Task
  • Clickworker

Patent Validation / Invalidation

  • Article One Partners is a private firm that helps corporate clients invalidate patents. A network of "AOP Associates" who have registered with the site can earn up to $50,000 for providing evidence of patent-invalidating "prior art."
  • Peer-to-Peer Patent Project also provides patent assessment, but it is not a true contest or market. The project is sponsored by the US Technology and Patent Office and NYU Law School and patent reviewers are not paid.

Finance

  • LendingClub facilitates unsecured lending between individuals.
  • Kiva
  • Prosper.com is a for-profit peer-to-peer lending site similar to LendingClub. As of January 2009, the site claims 830,000 members and $178,000,000 of loans.

Enabling Techologies and Organizations

Interested Third Parties

  • Turk Opticon is a website and Firefox plug-in that allows Amazon Mechanical Turk workers to rate "Requestors" who post work on the site. The Firefox plug-in allows workers to view the ratings in real time before deciding whether or not to accept a task from the requestor.

Online dating, later in life

Job markets have scrambles for late action, and it turns out that it's never too late for online dating either, the NY Times reports: Second Love at First Click

"If you think online dating is the domain of the young, maybe it’s time to check in with your mother. Now, people 55 and older are visiting American dating sites more than any other age group — up 39 percent in the last three years, according to the Internet tracking firm Experian Hitwise. The No. 2 group? Singles 45 to 54. According to IBISWorld, a market research firm, and the United States Census Bureau, about 37 percent of people 50 and older are unmarried. And the divorce rate among the 50-plus demographic is high. With so many older Americans unattached, living independently into their later years, and increasingly comfortable using the Internet, they, too, are logging on for love.

"And they may be better at finding it than their younger cohorts. Dating industry professionals say that singles in their 20s and 30s are typically focused on marriage and starting a family, while older singles (many of whom have been married before) have a more relaxed approach and are careful to pick companions who share their interests.

“Baby boomers have been one of the fastest-growing demographics for a lot of online dating companies,” said Caitlin Moldvay, an analyst for IBISWorld. The growth comes at the same time that some younger singles (18 to 34) are moving away from dating sites to social networking sites like Facebook as “a proxy for online dating,” said Bill Tancer, the general manager of global research for Experian Marketing Services.

"Greg Liberman, the president and chief executive of Spark Networks — which owns specialty dating sites including JDateChristianMingleBlackSinglesSilverSingles — said that for the first eight months of this year, Spark had a 93 percent increase in new members 50 and older across all of its dating sites, compared with the same span of time last year. “We’re seeing significant growth,” Mr. Liberman said.

"He’s also observed that, while it’s been common for parents to buy dating site memberships for their adult children, now adult children have begun buying memberships for their widowed and divorced parents. Gone is the heyday of personal ads in The New York Review of Books."

Mike Luca on Yelp

My colleague Mike Luca (whose work I wrote about here when he was still a grad student) has a paper on the influence of Yelp reviews on restaurant revenues.

It's recently been receiving some attention both locally at HBS working knowledge, and in the larger blogosphere: One-Star Bump On Yelp Leads To Big Revenue Boost, Study Finds

Here's the abstract of his paper:
"Do online consumer reviews affect restaurant demand?  I investigate this question using a novel dataset combining reviews from the website Yelp.com and restaurant data from the Washington State  Department of Revenue.   Because  Yelp prominently displays a restaurant's rounded average rating,  I can  identify the  causal  impact of Yelp ratings on demand with a  regression discontinuity framework that exploits Yelp‟s rounding thresholds.  I present three findings about the impact of consumer reviews on the restaurant industry: (1) a one-star increase in Yelp rating leads to a  5-9 percent increase in revenue, (2) this effect is driven by independent restaurants; ratings do not affect restaurants with chain affiliation, and (3) chain restaurants have declined in market share as Yelp penetration has increased. This suggests that  online  consumer reviews substitute for more traditional forms of reputation. I then test whether  consumers use these reviews  in a way that is consistent with standard  learning models.  I present  two additional findings: (4) consumers do not use all available information and are more responsive to quality changes that are more visible and (5) consumers respond more strongly when a rating contains more information.  Consumer response to a restaurant‟s average rating is affected by the number of reviews and whether the reviewers are certified as “elite” by Yelp, but is  unaffected by the size of the reviewers‟ Yelp friends network."

Dating sites for French farmers

If a dating site specializing in French farmers sounds specialized to you, consider the special problems of farmers: they are unusually immobile, as their work is typically tied to a specific plot of land, and they don't meet many potential marriage partners in the course of a typical work day.  So their problem combines those that have given rise to other kinds of specialized dating sites that make a thick market for e.g. particular ethnic groups or people with disabilities, as well as location and career choice.

The NY Times has a nice article by MAÏA de la BAUME covering several such sites: With Help Online, French Farmers Now Playing the Field

"The lack of love in the countryside is a serious topic for a country that sees its bedrock in small farmers and their produce, which is supposed to be uniquely of the place where it is grown. According to the Agriculture Ministry, about 30 percent of male French farmers did not have a partner in 2009."

The New Yorker on Online Dating

Nick Paumgarten in the New Yorker: Looking for Someone

"Online dating sites, whatever their more mercenary motives, draw on the premise that there has got to be a better way. They approach the primeval mystery of human attraction with a systematic and almost Promethean hand. They rely on algorithms, those often proprietary mathematical equations and processes which make it possible to perform computational feats beyond the reach of the naked brain. Some add an extra layer of projection and interpretation; they adhere to a certain theory of compatibility, rooted in psychology or brain chemistry or genetic coding, or they define themselves by other, more readily obvious indicators of similitude, such as race, religion, sexual predilection, sense of humor, or musical taste. There are those which basically allow you to browse through profiles as you would boxes of cereal on a shelf in the store. Others choose for you; they bring five boxes of cereal to your door, ask you to select one, and then return to the warehouse with the four others. Or else they leave you with all five.  

"It is tempting to think of online dating as a sophisticated way to address the ancient and fundamental problem of sorting humans into pairs, except that the problem isn’t very old. Civilization, in its various guises, had it pretty much worked out. Society—family, tribe, caste, church, village, probate court—established and enforced its connubial protocols for the presumed good of everyone, except maybe for the couples themselves. The criteria for compatibility had little to do with mutual affection or a shared enthusiasm for spicy food and Fleetwood Mac. Happiness, self-fulfillment, “me time,” a woman’s needs: these didn’t rate. As for romantic love, it was an almost mutually exclusive category of human experience. As much as it may have evolved, in the human animal, as a motivation system for mate-finding, it was rarely given great consideration in the final reckoning of conjugal choice.


"The twentieth century reduced it all to smithereens. The Pill, women in the workforce, widespread deferment of marriage, rising divorce rates, gay rights—these set off a prolonged but erratic improvisation on a replacement. In a fractured and bewildered landscape of fern bars, ladies’ nights, Plato’s Retreat, “The Bachelor,” sexting, and the concept of the “cougar,” the Internet promised reconnection, profusion, and processing power.

"The obvious advantage of online dating is that it provides a wider pool of possibility and choice. In some respects, for the masses of grownups seeking mates, either for a night or for life, dating is an attempt to approximate the collegiate condition—that surfeit both of supply and demand, of information and authentication. A college campus is a habitat of abundance and access, with a fluid and fairly ruthless vetting apparatus. A city also has abundance and access, especially for the young, but as people pair off, and as they corral themselves, through profession, geography, and taste, into cliques and castes, the range of available mates shrinks. We run out of friends of friends and friends of friends of friends. You can get to thinking that the single ones are single for a reason.
...
"Match.com, one of the first Internet dating sites, went live in 1995. It is now the biggest dating site in the world and is itself the biggest aggregator of other dating sites; under the name Match, it owns thirty in all, and accounts for about a quarter of the revenues of its parent company, I.A.C., Barry Diller’s collection of media properties. In 2010, fee-based dating Web sites grossed over a billion dollars. According to a recent study commissioned by Match.com, online is now the third most common way for people to meet. (The most common are “through work/school” and “through friends/family.”) One in six new marriages is the result of meetings on Internet dating sites.

 ...
"There are thousands of dating sites; the big ones, such as Match.com and eHarmony (among the fee-based services) and PlentyOfFish and OK Cupid (among the free ones), hog most of the traffic. Pay sites make money through monthly subscriptions; you can’t send or receive a message without one. Free sites rely on advertising.
...
"I had a talk-about-dating date with a freelance researcher named Julia Kamin, who, over twelve years as a dater on various sites, has boiled down all the competing compatibility criteria to the question of, as she put it, “Are we laughing at the same shit?” This epiphany inspired her to build a site—makeeachotherlaugh.com—on which you rate cartoons and videos, and the algorithms match you up. As she has gone around telling people about her idea, she says, “women get instantly excited. Men are, like, ‘Um, O.K., maybe.’ ” It might be that women want to be amused while men want to be considered amusing. “I really should have two sites,” Kamin said. “Hemakesmelaugh.com and shelaughsatmyjokes.com.” (She bought both URLs.)

...
"The online dating sites are themselves a little like online-dating-site suitors. They want you. They exaggerate their height and salary. They hide their bald spots and back fat. Each has a distinct personality and a carefully curated profile—a look, a strong side, and, to borrow from TACT, a philosophy of life values. Nothing determines the atmosphere and experience of an Internet dating service more than the people who use it, but sometimes the sites reflect the personalities or predilections of their founders.


"OK Cupid, in its profile, comes across as the witty, literate geek-hipster, the math major with the Daft Punk vinyl collection and the mumblecore screenplay in development. Get to know it a little better and you’ll find that it contains multitudes—old folks, squares, more Jews than JDate, the polyamorous crowd. Dating sites have for the most part always had either a squalid or a chain-store ambience. OK Cupid, with a breezy, facetious tone, an intuitive approach, and proprietary matching stratagems, comes close to feeling like a contemporary Internet product, and a pastime for the young. By reputation, it’s where you go if you want to hook up, although perhaps not if you are, as the vulgate has it, “looking for someone”—the phrase that connotes a desire for commitment but a countervailing aversion to compromise. Owing to high traffic and a sprightly character, OK Cupid was also perhaps the most desirable eligible bachelor out there, until February, when it was bought, for fifty million dollars, by Match.

"OK Cupid’s founders, who have stayed on since the sale, are four math majors from Harvard.
...
"OK Cupid sends all your answers to its servers, which are housed on Broad Street in New York. The algorithms find the people out there whose answers best correspond to yours—how yours fit their desires and how theirs meet yours, and according to what degree of importance. It’s a Venn diagram. And then the algorithms determine how exceptional those particular correlations are: it’s more statistically significant to share an affection for the Willies than for the Beatles. The match is expressed as a percentage. Each match search requires tens of millions of mathematical operations. To the extent that OK Cupid has any abiding faith, it is in mathematics.


"There’s another layer: how to sort the matches. “You’ve got to make sure certain people don’t get all the attention,” Rudder said. “In a bar, it’s self-correcting. You see ten guys standing around one woman, maybe you don’t walk over and try to introduce yourself. Online, people have no idea how ‘surrounded’ a person is. And that creates a shitty situation. Dudes don’t get messages back. Some women get overwhelmed.” And so the attractiveness ratings, as well as the frequency of messaging, are factored in. As on Match.com, the algorithms pay attention to revealed preferences. “We watch people who don’t know they’re being watched,” Sam Yagan, the company’s C.E.O., said. “But not in a Big Brother way.” The algorithms learn as they go, changing the weighting for certain variables to adjust to the success or the failure rate of the earlier iterations. The goal is to connect you with someone with whom you have enough in common to want to strike up an e-mail correspondence and then quickly meet in person. It is not OK Cupid’s concern whether you are suited for a lifetime together.

Susan Athey on online experiments

My colleague Susan Athey (in whose class I'll be guest lecturing today) speaks to NPR:

"Susan Athey: Did you know that every time you do a search on Google or Bing, you are improving the quality of the search engine? The more people click on a search advertisement from a clothing company or on a link on an online news story, the more prominently it is displayed for the next consumer. And the firms constantly experiment to get things right. They watch what consumers do and adapt their products in response to the results of their experiments.


"But designing the right experiment is difficult. To see just one example, consider spam. An e-mail provider wants to eliminate spam from your inbox. It is nuisance for all of us. That company might test out a new way to filter spam. The filter may do a great job in short-term experiments, where the spammers don't have a chance to respond. But once the new filter is introduced in practice, spammers may find a way around the filter. So, that means that some legitimate e-mail is filtered out and the end result may be that you haven't solved the spam problem at all. You could very well end up worse than where you started, even though the experimental numbers looked great.

"So, if you want to figure out whether a new product will work out the way you hope, you need to be able to anticipate how people will react to your innovation. That is, you don't just have to be a good statistician. It's not just about the numbers that come out of simple experiments; it is about predicting how people will react to the changes you make. You need to understand behavior and how to build models that reflect the choices we all make.

"Unfortunately, our universities and business schools haven't figured out how to train students to do this kind of modeling and prediction. That is, we aren't preparing students to manage the new data-driven businesses. And let's face it: This is where our economy is headed, as consumers are spending more and more of their time online. Creating new jobs in this economy is a must, but making sure that the workforce is ready for the jobs where our growth is happening is more important. The good news is that the young people who do develop the talent and skills to capitalize on this opportunity will be in high demand, which puts them in a great position in today's tough economy."

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.”

Online real estate markets: Yahoo and Zillow

Yahoo Pairs with Zillow on Real Estate Listings

"The deal also helps Yahoo and Zillow challenge Move Inc. (MOVE), owner of Realtor.com, the most-used real estate site."
...
"Until now, Yahoo has focused mainly on selling ads from large marketers, such as mortgage companies and credit agencies, not the local real estate agents that are Zillow's mainstay, Schultz said. In May, Yahoo was No. 3 in the online real estate market with 6.14 million users, while Zillow.com was second with 7.05 million, according to ComScore (SCOR) of Reston, Va. The market was led by Move Inc., with more than 12 million."

Sex domain .xxx approved by regulators .
"ICANN, the Internet Corporation of Assigned Names and Numbers, which is responsible for overseeing the creation and distribution of web addresses, finally gave the go-ahead for the special .xxx domain name at a meeting in Brussels.

The adult entertainment industry has long campaigned in favour of a special .xxx suffix, similar to the .com and .co.uk domain names used by other companies."
