Matchmaking for pet dogs in India

The New York Times reports on an emerging problem of dogs owned by the Indian middle class: Matchmaking in India: Canine Division

"“When a customer goes and buys a dog, 99 percent go for a male, and down the road when they need a mate, they face a problem,” Mr. Chopra said.
He tried his hand at pet matchmaking, linking males and females of the same breeds, but it was simply impossible to find matches. Most of the females remain with breeders, he said, who prefer professional stud dogs. This also helps keep the supply of popular breeds tight — if people cannot breed dogs in their backyard they cannot cut into breeders’ profits."

Dog fighting

Here's a Texas story about an undercover police operation--with the undercover policemen hosting a number of fights--that led to many arrests for conducting dog fights. After the arrests, the fighting dogs were put down. So it's a story about repugnant transactions, from several points of view...

Bringing Down the Dogmen: How a pair of undercover cops infiltrated the secret world of Houston dogfighting.

"For centuries, dogfighting was perfectly legal. In Rome’s Colosseum, gladiator dogs were pitted against one another or against other animals, including wild elephants. One of the more popular forms of entertainment in twelfth-century England was “baiting,” in which fighting dogs would be released into a ring with chained bulls and bears. In the colonial United States dogfights were common, and they continued well into the nineteenth century, with formal rules and sanctioned referees. As recently as 1881, the Ohio and Mississippi Railroad advertised special fares to a dogfight in Louisville, Kentucky.
Eventually, because of protests by such groups as the American Society for the Prevention of Cruelty to Animals, states began passing legislation that banned dogfights. By the thirties, dogfighting had been driven almost completely underground. Nevertheless, it remained a culturally ingrained phenomenon that simply refused to go away—a fact that became all too clear when Michael Vick, the quarterback of the Atlanta Falcons, was indicted by a grand jury in July 2007 for operating a dogfighting ring on his Virginia farm and later sentenced to two years in prison. The vast majority of Americans were stunned. Why, they wanted to know, would a young multimillionaire celebrity risk everything to engage in what they regarded as a barbaric practice?"

Here's an earlier post.

Update: the article is now gated (it wasn't when I read it). Here is an ungated followup article by the same author: Fight Club. Here is a followup by a different author: What Texas Monthly left out about 'bringing down the dogmen'

The education business: Stanley H. Kaplan R.I.P.

Education isn't a marketplace that supports only schools; it also supports test making companies, and test preparation companies. The founder of the big SAT prep company just passed away: here's an obit from the Chicago Trib. Stanley H. Kaplan, 1919-2009: Founded popular test-prep company.

The Atlantic has this to say. Stanley H. Kaplan's Legacy.

The Chronicle of Higher Ed's story contains this: "And as his business grew, all sorts of other commercial educational interests began to expand their influence on the academy. Today, the higher-education industry includes not only giant for-profit institutions like DeVry University, the University of Phoenix, and the degree-granting colleges of Kaplan itself, but also course-management companies like Blackboard Inc. and eCollege, distance-learning outsourcers like Higher Ed Holdings, and student-coaching and tutoring companies like Inside Track and Smartthinking."

The sending and transmitting and facilitating of signals is a big business, in college admissions as elsewhere. (Indeed, there's a big part of economic theory that looks on a college education itself as a costly signal sent by the teachable...)

Coming of Road Rage in Samoa

Unless the government backs down, Samoa will change from driving on the right to driving on the left (British Commonwealth style) on September 7:

Shifting the Right of Way to the Left Leaves Some Samoans Feeling Wronged
Government Calls Traffic-Rule Switch 'Common Sense,' but It Sparks Road Rage
.

This is one of those cases in which it clearly helps everyone to have a clear rule about which side of the road to drive on, and a little government regulation (and even inter-government coordination) can promote efficient traffic flow. (Think of the congestion at the borders at which you had to switch from driving on one side to driving on the other.)

But it isn't obvious that there's a "right" side, especially since Samoa is an island, and doesn't have to coordinate with anyone who can drive to Samoa from somewhere else. (The last country in continental Europe to switch sides--from driving on the left to driving on the right--was Sweden, in 1967.) Here's a nicely written historical account (whose accuracy I can't vouch for): Why do some countries drive on the right and others on the left ?

(I particularly liked their description of the decision in Pakistan: "Pakistan also considered changing to the right in the 1960s, but ultimately decided not to do it. The main argument against the shift was that camel trains often drove through the night while their drivers were dozing. The difficulty in teaching old camels new tricks was decisive in forcing Pakistan to reject the change.")

The government of Samoa believes that the benefits of switching will come from enabling Samoans to buy used cars from the left-driving Australians and New Zealanders.

But the proposal to switch sides is not without costs, since the current stock of cars has the driver sitting on the left, which will make some things (like passing) harder if traffic is switched to the left side of the road. (And of course the current stock of school buses will have to load and unload children from the middle of the street, instead of from the curb.)

It looks like September 7 might be a good day to avoid the roads, if you happen to be in Samoa. (And here's an earlier post on New Zealand traffic rules .)
*********

Update: Samoa switches smoothly to driving on the left
"Samoa is the first country in decades to change the direction of traffic. Iceland and Sweden did it in the 1960s, and Nigeria, Ghana and Yemen did it in the 1970s."

Ecclesiastical Insurance

Before you read this post, what do you think Ecclesiastical Insurance insures against? (It turns out to have more to do with hot lead than with lost souls...)



The Church of England is under attack, and not just from the usual schismatics. Here's the story: Church of England fights fiddlers on the roof


"THE Church of England is using nanotechnology – the science of very small things – to fight thieves who strip lead and other valuable metals from the roofs of its ancient buildings.
More than 30,000 of Britain’s 44,000 churches have had their roofs coated in a layer of “nanopaint”, which is visible only under ultraviolet light.
Each church has a different blend of microscopic particles, giving its metal a unique “label”. This enables police to identify church lead found in any haul of suspect scrap, even if it has been melted down."
...
"Recently, church authorities scored a victory in the battle against thieves with the conviction of three men for stealing lead from the roof of St Leonard’s church in Colchester, Essex.
They were caught after police identified the lead stolen from the church on sale at a scrapyard by using the new labelling system."
...
"The number of insurance claims for metal thefts from churches has risen from just 12 in 2002 to more than 2,500 last year – attacks described by Peter Walley, chaplain to the bishop of Lichfield, as “the biggest asset-stripping of churches since the dissolution of the monasteries”."
...
"The demand for scrap is driven by world prices. Those for lead and copper soared to record levels last year with scrap lead peaking at £1,300 a ton. Metal prices fell when the recession hit, but are now picking up again strongly.
Most churches are insured by Ecclesiastical Insurance, which is so concerned at the losses that it recently sent every church a SmartWater kit and warned vicars and bishops it would pay out no more than £5,000 if they failed to use it on their roofs.
A spokesman for Ecclesiastical Insurance said metal theft had become the number one reason for claims. "

What if they ran an auction and nobody came?

David Fahrenthold writes in the Washington Post about Maryland's unsuccessful attempt to buy back some crab fishing licenses via an auction:
To Some Chesapeake Crabbers, a $50 Document Is Priceless
"Despite Industry's Woes, Many Watermen Refuse to Sell Symbol of Old Way of Life"

Apparently the licenses have value even to those who don't currently use them to catch crabs. The right to take crabs is what makes you a waterman...

Investing in law suits

"To press a suit" means something different to a tailor and to a lawyer. Now investors are getting involved too.

Investing in Lawsuits, for a Share of the Awards
"A small but growing number of investors are exploring this idea, helping companies avoid some of the risks and costs of litigation in exchange for part of any money paid out when the case is settled or resolved by a court."

This reflects some broader changes in the law biz, somewhat related to developments in patent and class action law.

Regarding patents, firms that invest in patents with an eye towards making money from infringement law suits are known by those who dislike them as patent trolls (see here, too). There is both an offensive and a defensive part of that business, and both attract investors, see e.g. Trolling for Patents to Fight Patent Trolls.

Another kind of lawsuits that involve investors are class action suits. Here the investors are often a consortium of law firms that can pool otherwise unbillable hours to devote to a large speculative project that will only pay off in case of a favorable decision or settlement. The theory behind class action is that it should allow the law to bear on malefactors who might harm many people, but each too little to justify the expense of an individual lawsuit. (E.g. a supermarket chain that systematically overcharged everyone twelve cents might eventually be found liable to pay damages to a large class of consumers. If you noticed them doing this, you wouldn't be able to interest a law firm in representing you as an individual plaintiff, but might be able to interest a firm in representing the whole class.) Class action law envisions the firms as responding to claims presented by plaintiffs, and a plaintiff who claims harm is needed to bring the case. But there's a big advantage to being the first firm (or consortium) to bring a class action law suit, since the originating law firms get to represent the whole class of plaintiffs. So there's a temptation for an entrepreneurial firm to go out and hire some plaintiffs, which is against the law. One of the biggest class action firms fell to this temptation: Class-Action Firm Agrees to Pay $75 Million to Settle Kickback Case

Automated spam blog detection

Woke up this morning to find this on my blog dashboard:

"This blog has been locked due to possible Blogger Terms of Service violations. You may not publish new posts until your blog is reviewed and unlocked.
This blog will be deleted within 20 days unless you request a review."

And this in my email:
"Your blog at: http://marketdesigner.blogspot.com/ has been identified as a potential spam blog. To correct this, please request a review by filling out the form at http://www.blogger.com/unlock-blog.g?lockedBlogID=4748060798655400108

Your blog will be deleted in 20 days if it isn't reviewed, and your readers will see a warning page during this time. After we receive your request, we'll review your blog and unlock it within two business days. Once we have reviewed and determined your blog is not spam, the blog will be unlocked and the message in your Blogger dashboard will no longer be displayed. If this blog doesn't belong to you, you don't have to do anything, and any other blogs you may have won't be affected.

We find spam by using an automated classifier. Automatic spam detection is inherently fuzzy, and occasionally a blog like yours is flagged incorrectly. We sincerely apologize for this error. By using this kind of system, however, we can dedicate more storage, bandwidth, and engineering resources to bloggers like you instead of to spammers.

Let's see if I can publish this. (Update: it looks like I can still publish, but have to interpret a captcha to show I'm probably human...)

Further update: how could Google's automatic spam blog detector be improved? Well, Google offers a lot of tools for reading blogs. Some fraction of my regular readers apparently read Market Design on Google Reader, since it reports 858 subscribers when I checked just now. (You can check too, or subscribe, by going to Google Reader and typing "market design" after clicking on the + box next to "add a subscription." You aren't committed at that point, but you can see the feed, and the number...)

So, a thought for the humans who program the automatic spam detector: check if spam blogs have fewer subscribers than real blogs, and, if so, include that in the next version of the algorithm.

Identifying desirable spouses

Empirical researchers who use matching models to study matching markets such as marriage are often faced with the difficulty that they can observe the results of the market--e.g. who marries whom--but not the intermediate choices that produced these matches (such as who courted whom, who proposed and was rejected, etc.). One approach is to look for particular markets in which such additional data can be found (as in these studies in India, the U.S., and Korea). Another is to develop statistical tools to infer the missing data, e.g. about the preferences of men and women, from the readily observable outcomes.

A NBER working paper that takes this latter approach is Identification in Matching Games, by Jeremy T. Fox - http://papers.nber.org/papers/W15092.

Here's the first paragraph from the introduction:
"Matching games are a new and important area of empirical interest. Consider the classic example of marriage. A researcher may have data on a set of marriages in each of a set of independent matching markets, say a set of towns. The researcher observes characteristics of each man and each woman in each town, as well as the sets of marriages that occurred. The researcher observes equilibrium outcomes, here marriages, and not choice sets, so identification in this type of model will not be able to rely trivially on the analysis of single-agent demand models. What type of parameters can be identified from these data?"

And here's the formal abstract:
Abstract: I study a many-to-many, two-sided, transferable-utility matching game. Consider data on matches or relationships between agents but not on the choice set of each agent. I investigate what economic parameters can be learned from data on equilibrium matches and agent characteristics. Features of a production function, which gives the surplus from a match, are nonparametrically identified. In particular, the ratios of complementarities from multiple pairs of inputs are identified. Also, the ordering of production levels is identified.

The market for bulk commodity shipments

The transport of bulk commodities by sea is a business that depends on matching loads to ships. When times are good, ships may be fully booked, and costly, and when times are bad ships may be available and cheap.

"The Baltic Exchange is an association of ship owners, and has a long and colorful history. Because shipping prices are an indicator of the general economy, the Baltic Exchange Dry Index, which measures the cost of hiring a big ship, is a leading indicator of commodities trading in particular and of economic activity in general.

As recently adjusted, the components of the index are indices for different kinds of shipping, in order of cargo capacity: Capesize (too big to transit the Suez canal, so have to go around), Panamax (the maximum size ship that can go through the Panama canal), Supramax, and Handysize.

Hotel rooms and discounts

I just received an ad by email for a prizewinning hotel in Boston. When I went to their website, I found that their seasonal room rate for a weekday in late September for two adults is $285.00 Their site also makes it easy to check the special rates they give to those who are members of the AAA, AARP, and the U.S. Government. For the same day and same room, those rates were, when I checked, respectively, $355.50, $355.50, and $306.00 . Gotta love that government discount.

Factoring

If you do a google search on "factoring," the first few organic results are on factoring numbers, but the ads are all about factoring receivables. Factors (in this sense of the word) are firms that lend cash to businesses, on the strength of their accounts receivable. It used to be (and still largely is) a relationship business; one factor would handle all of a firm's receivables.

The Street.Com has an article on the new face on the block, The Receivables Exchange , which is set up around the idea of letting firms borrow from individual investors on the strength of particular accounts receivable: Cash-Strapped Firms Sell Unpaid Accounts.

"Cash flow has become a leading concern for small firms as banks reduce credit lines, shorten maturities and raise rates, according to a May study by the Credit Research Foundation. Among the companies surveyed, 45% said the financial crisis was straining their access to working capital. Almost 70% reported a slowdown in customer payments, and 61% said their top priority was to boost cash flow by getting clients to pay what they owe faster.
The Receivables Exchange (TRE), which runs an online auction market for accounts receivable, is benefiting from these trends. More companies have been turning to the two-year-old firm to raise money as traditional credit sources dry up.
"We take the most liquid of the assets on the balance sheet that they can modify and allow those to trade on a transparent, standardized exchange," says Nicolas Perkin, president of the New Orleans-based company.
With TRE's online system, which one might describe as an eBay... for factoring, sellers post eligible receivables and set sale parameters, such as the duration of the auction, the minimum advance payment and the maximum fee they will pay.
Buyers, such as commercial banks and hedge funds, browse for accounts to bid on and post profiles indicating their preferences. Sellers can leave the auction open-ended or set a "buyout price" that allows a buyer to immediately snap up the accounts.

TRE has almost $20 billion of liquidity up for grabs. The average seller is looking to unload $65,000 of accounts receivable. The average auction lasts one day, with the shortest clocking in at less than a minute. The company has a 99% completion rate, with upwards of 85% selling at the buyout price. About 86% of users are repeat customers. "

I've written about TRE before, here and here.

Update: Steve Leider points me to this Marketplace Whiteboard video explaining Factoring, inspired by the recent troubles of CIT, a big factor.

U.S. black market for kidneys, continued

The AP takes up the story of a man who says he sold his kidney in NY for $20,000, and who posted a video on the web. Here's the publication of the story by MSNBC, which includes the video: Man says he sold kidney in U.S. for $20k. (The video isn't full of information, but the kidney content begins just after minute 5.)

"In 2005, a rebellious and sporadically employed Israeli man flew to New York to give up a kidney to save an American businessman. For that, he says he was paid $20,000, which appeared in a brown envelope on his hospital bed after the operation.
...
"Rosen believes he did a good deed and that organ donors like him should be compensated. Much of his story can be confirmed, and the case gives new resonance to claims that a black market for kidneys has thrived even in the United States."

Here's my earlier post on Black market for kidneys: in the US? , and here's the long list of posts on compensation for donors generally.

Bob Aumann speaks in SA about game theory and market design


Bob Aumann has been lecturing in South Africa, and speaking about game theory as the foundation of market design, South Africa's Business Day reports: Game theory has a host of practical applications .

"Aumann thinks moving from game theory to game engineering will help us. Theory can be used to design practical interactive systems — the US auctions being a good example. But he says governments in particular must understand the power of incentives to drive economic and political actors, and work towards creating systems that get the best from them."

Licensing of Lawyers and Doctors and some more surprising professions

Can it be that Texas has only 22 licensed matchmakers?
(But 73 licensed ringside physicians?)
You can search Texas licenses by type here , in a drop down menu that starts with airconditioning contractors and ends with water well drillers, with matchmakers and many others in between.

Licensing plays a big role in the regulation of some markets, and not just the markets you would suspect, like those for doctors and lawyers. Some of the questions that come up in the licensing biz can be gleaned from the url's of the decisions they generate, like this one: http://www.license.state.tx.us/cosmet/cosmet.htm#eyelashes .
(That's from the Statement from TDLR about applying false eyelashes, eyelash tabbing and eyelash extensions and whether a person must hold a cosmetology license in order to perform these procedures.)

And, since you asked, here's the Texas ruling on fish pedicures.

Across state lines, there's some uniformity in how doctors and lawyers are treated, although not so much that moving from state to state is always easy. And there are some notable differences between doctors and lawyers.

Q. In how many states can a new medical school graduate be licensed to practice medicine right after passing the necessary exams (i.e. before doing at least one year of supervised clinical experience as a resident)?

A. Zero (although no information is available at this time on the Solomon Islands and the Northern Marianas, see State-specific Requirements for Initial Medical Licensure compiled by the Federation of State Medical Boards.

Q. In how many states can a new law school graduate be licensed to practice law after passing the necessary exams?

A. In all of them, unless I'm badly misreading the Comprehensive Guide toBar Admission Requirements 2009, published by the National Conference of Bar Examiners.

Q. What do Mississipi, Missouri, Texas and the Northern Marianas Islands have in common?
A. Those are the American jurisdictions in which a felony conviction is an automatic bar to admission to the legal bar, according to "CHART II: Character and Fitness Determinations" in the link above. (That doesn't mean felons get a free pass in other jurisdictions, just that their disqualification isn't categorical and automatic. E.g. in Florida, a felony conviction is "Not an automatic bar, but restoration of civil rights is required.")

Health care as a protected transaction

President Obama makes the case that health care, and health insurance, should be protected transactions (and that some existing insurance practices are repugnant):

"Our reform will prohibit insurance companies from denying coverage because of your medical history. Nor will they be allowed to drop your coverage if you get sick. They will not be able to water down your coverage when you need it most. They will no longer be able to place some arbitrary cap on the amount of coverage you can receive in a given year or in a lifetime. And we will place a limit on how much you can be charged for out-of-pocket expenses. No one in America should go broke because they get sick. "

From Why We Need Health Care Reform by Barack Obama

Paul Romer on market design

Paul Romer, at Charter Cities, thinks of market design as part of the economics of ideas, in his post on Fish Proverb v2.0 (Bringing in Rules):

"Most of the work on the economics of ideas has focused exclusively on a subset of ideas, technologies. Economists have been slower to acknowledge the complementary set of ideas, rules. "

Indian court decriminalizes gay sex

Another court, in another democracy, finds that an ancient repugnance violates another constitution: Indian court decriminalises gay sex.

"An Indian court has ruled for the first time that consensual gay sex is not a crime, in a breakthrough for Aids campaigners and the country’s largely closeted homosexual community. "
...
"“Consensual sex amongst adults is legal which includes even gay sex,” said a two-judge bench after considering a petition against the law. "

Where it's illegal for prostitutes to give massages

The complicated legal situation in Rhode Island makes indoor prostitution legal, but requires masseurs to be licensed, so prosecutors "brought charges against alleged brothels for performing unlicensed massages."

This from a story by Sarah Schweitzer in today's Boston Globe, Many seek ban as prostitution thrives in R.I..

The debate over whether to change the law and (re)criminalize indoor prostitution is revealing, and suggests some of the complexities underlying repugnance to prostitution.

"Prostitution has flourished in Rhode Island, and the state has the distinction - a dubious one, many say - of being the only state in the nation to permit what is often referred to as indoor prostitution, a phrase that distinguishes it from streetwalkers’ solicitations. (In Nevada, the practice is permitted only in certain counties.)
Legislators have repeatedly proposed banning all prostitution in the state, without success. Yet, as the number of spas has exploded in recent years, pressure has mounted for change. This year, both the House and the Senate passed separate antiprostitution bills. Legislative leaders are now trying to hammer out a compromise with the backing of Governor Donald Carcieri."

"Leaders of the push to ban indoor prostitution say Rhode Island is encouraging a dangerous profession, and embarrassing itself in the process.
...
"In addition to support from Carcieri, Giannini’s bill has won backing from Bishop Thomas J. Tobin of the Roman Catholic Diocese of Providence and state Attorney General Patrick Lynch."

"Opponents also have a broad spectrum of support, including local chapters of the American Civil Liberties Union and the National Organization for Women, and a group of academics from around the globe who recently penned an open letter to the Rhode Island Legislature saying that, “compared to street workers, women and men who work indoors generally are much safer and less at risk of being assaulted, raped, or robbed.’’ "
