Regulating fast trading on Wall St
"Supercomputers allow certain traders to profit by executing trades in milliseconds, a practice known as high-frequency trading. These traders also use a technique called flash orders that gives them a sneak peek at other investors’ orders to buy and sell stock. ...
"...similar criticisms have been made for over 100 years, since the days when trades on the New York Stock Exchange were executed by humans using notepads and pencils.
Even back then, critics claimed that the exchange members who were physically present on the floor could get trading information and execute their own orders faster than anyone else. The creation of the Securities and Exchange Commission in 1934 included the power to regulate the buying and selling of securities by exchange members trading for themselves, rather than for customers.
A Roosevelt administration official testifying in support of the 1934 legislation, Thomas Corcoran, described such floor traders as “chiselers.” This referred to their ability to quickly buy from sellers at prices lower than they would otherwise get, and promptly resell to buyers at prices higher than they would otherwise pay.
These complaints were well founded. By being on the exchange floor, traders could see with their own eyes the prices of completed trades minutes before they appeared on the exchange tape. Executing their own orders gave them a head start over ordinary investors, whose orders could take minutes to reach the floor. As a former Wall Street Journal editor wrote in 1903, “They know the prices even before they are recorded on the tape, and they are able to join in every upward movement the moment it begins, and to abandon it the moment it shows signs of wavering.”
In 1909, a committee created by Gov. Charles Evans Hughes of New York to study stock market abuses similarly commented that floor traders “acquire early information concerning the changes which affect the values of securities,” giving them “special advantages” over other traders. "

Market for (smuggled) cultural treasures
Ray Fisman and Shang-Jin Wei have a paper that attempts to measure how often such laws are flouted (by comparing export declarations and U.S. import declarations--not everything that is illegal to export is illegal to import). It's called "The Smuggling of Art and the Art of Smuggling: Uncovering the Illicit Trade in Cultural Property and Antiques ," AEJ-Applied Economics, 1,3,2009.
It turns out that the level of illegal exports from a country is correlated with how often its UN diplomats violate NYC parking regulations.

Cent mail: signalling that your email isn't spam
"Yahoo! Research's CentMail resurrects an old idea: that levying a charge on every email sent would instantly make spamming uneconomic. But because the cent paid for an accredited "stamp" to appear on each email goes to charity, CentMail's inventors think it will be more successful than previous approaches to make email cost. They think the cost to users is offset by the good feeling of giving to charity."
"Some previous schemes, such as Goodmail, simply pocketed the charge for the virtual stamps. Another deterred spammers by forcing computers to do extra work per email; and Microsoft's version requires senders to decipher distorted text."
Here's an earlier post.
Here's another story: Will Users Donate a Penny Per Email to Fight Spam, Yahoo Wonders, which notes"It’s not clear how much the proposal would help, however, since so much of the spam is now sent using botnets, which are networks of zombie PCs whose owners have no idea their computers are part of a massive spamming organization."

Congestion in online job search
"GETTING a rejection letter is a painful part of job hunting, but at least it means you’ve been noticed. These days, I’ve been hearing about more job hunters who respond to online job postings, only to hear nothing back from the company. Ever."
"...before you get too angry at companies that ignore you, consider what they are up against.
First, the Internet has made it absurdly easy to apply for jobs. This means that unqualified people are clogging the system with their wing-and-a-prayer applications.
Then add rising numbers of unemployed people. More job seekers — qualified, unqualified and desperate — are hitting the send button. Acknowledgments are going by the wayside as recruiters confront hundreds of applications for a single job.
In fact, organizations received 75 percent more applications, on average, in the first half of 2009, compared with the same period in 2008, according to a survey by the Corporate Executive Board, a network of executives and a research company. "
How about business-oriented social networks liked LinkedIn, in which people can recommend each other?
" "Obtaining an employee referral is a good move, as far as it goes. There is just one problem: Nowadays “the referral channel is jammed in the same way that other channels are jammed,” Mr. Safferstone said."
A fast auction for gift cards
A "fast auction" in which the high bidders buy themselves gift cards and compete for bonus amounts on the card, so that different cards sell at different discounts.
"Rackup’s team is lead by Marc Rochman and is supported by a board that includes Stanford Prof. Paul Milgrom, one of the most prominent experts in auction theory, and Duke Prof. Dan Ariely, author of “Predictably Irrational”. The company raised early-stage funding from the founders and some private investors, amounting up to $3.5 million."

Law firm recruitment, rescinded offers, etc.
Last year, the blog Above the Law urged students holding multiple summer offers to accept one quickly: Accept Your Offers: Stop Screwin' Around You Kids Screw Around Too Much.
"If you are a 2L sitting on multiple offers, could you please -- for the love of God -- accept one of them already, so the spots you don't want can be filled by other candidates? ... And it might be in your best interest as well. The career services office at U. Penn Law School sent around a letter to students today, urging them to make a decision:
We recommend that you do not wait until the expiration of the offer to render a decision... Wednesday, we learned that one of your 2L colleagues had their offer for employment rescinded before the expiration of the offer because the firm experienced a higher than usual acceptances from outstanding offers..."
This year, Above the Law suggests (tongue in cheek?) Accept Your Offers: All of Them.
"It seems to me that the "social compact" between firms and students has completely broken down. We've been living in a Hobbesian state of nature for almost a year now.
NALP tells students that they should not hold more than two offers open, or else. Or else what? As Jim Leipold, executive director of NALP, recently observed, "There are no NALP police."
As far as we know, NALP hasn't done anything to firms that have disrespected the 45-day "open offer" period. What are they going to do to students that accept more than two offers?
We asked NALP these questions directly. We asked why a student should be willing to follow the NALP guidelines when firms have flouted them with impunity during the recession. We asked why students should adhere to NALP guidelines when law school deans are saying that the firms will not.
We received no response. So now we're asking you:
Shouldn't an intelligent 2L accept every offer of summer employment he or she gets? If some firms revoke that offer quickly, so what? It's probably a firm you don't want to summer with anyway.
Once you've decided which firm to go with, you can politely decline the other offers you accepted..."
While I think that reputational concerns will prevent law students from accepting multiple offers, there is obviously a great deal of justified concern when law firms make offers and then rescind them (we're not just talking about summer offers now). Here is NALP's statement on rescinded offers (which begins "Please note: NALP's Principles and Standards do not condone rescinding offers. However, in recognition that rescission does occasionally occur, NALP presents this article with suggestions for ameliorating the situation. ")
NRMP to implement "managed scramble"
"The NRMP Board of Directors, meeting in Washington, DC on May 4, 2009, voted to proceed with implementation of a "managed" Scramble for the Main Residency Match. A joint NRMP-AAMC work group will continue to refine the plan, which will require programs to offer and applicants to accept unfilled positions through the NRMP R3 System during Match Week. A "managed" Scramble would be implemented no earlier than the 2011 Match, according to NRMP Executive Director Mona M. Signer. " (http://www.nrmp.org/ on 9/13/09)

Playing the admissions game
Playing the Admissions Game: Student Reactions to Increasing College Competition by John Bound, Brad Hershbein, Bridget Terry Long - #15272 (ED LS)
Abstract: Gaining entrance to a four-year college or university, particularly a selective institution, has become increasingly competitive over the last several decades. We document this phenomenon and show how it has varied across different parts of the student ability distribution and across region, with the most pronounced increases in competition being found among higher-ability students and in the Northeast.
Additionally, we explore how the college preparatory behavior of high school seniors has changed in response to the growth in competition.
We also discuss the theoretical implications of increased competition on longer-term measures of learning and achievement and attempt to test them empirically; the evidence and related literature, while limited, suggests little long-term benefit.
http://papers.nber.org/papers/W15272
"Overall, high school students in 2004 engaged in significantly more behavior associated with college preparation, on average, than did their counterparts from 10 and 20 years before. The share taking at least a semester of calculus in high school rose from 9.2 percent to 15.2 percent between 1982 and 2004. In just the 12 years from 1992 to 2004, the fraction of seniors having taken at least one Advanced Placement (AP) exam nearly doubled, from 16.5 to 30.9 percent." (p12) (but reported time spent on homework is down)
"...data from CIRP's Freshman Survey shows that the percentage of college
freshmen who regularly volunteered during their senior year of high school increased rapidly from about 45 percent in 1987 and 1988 up to about 70 percent by 2000, where it has roughly remained since." (p14)
"While 25 percent of students had applied to four or more schools in 1972, more than half had by 2004. Figure 4 shows that the percentage of students applying to seven or more schools rose from about 3 percent in 1972 to 18 percent in 2004. This implies that more than half of the increase among those applying to four or more schools is driven by those applying to seven or more schools; within the last ten years, more than three quarters of the increase
is from those applying to seven or more schools. The increase in application rates has been widespread throughout the selectivity distribution, with students at highly selective institutions not only sending more applications on average, but also increasing the number of applications sent at a faster pace earlier on.
Another proxy for college application behavior is the number of SAT score reports sent to various colleges.16 When taking the SAT, students are allowed to send up to four score reports at no additional marginal cost. However, in recent years, students have been sending far more score reports. As shown in the three panels of Figure 5, the number of scores sent (and the likelihood of sending more than four) rises dramatically with the student's score. For those with scores above 1400 (around the 97th percentile), the median number of reports sent is around eight, which suggests that even students with very high scores do not feel that they can rely on being accepted into a top school." (p19)
Penny wise and pound foolish on kidneys and antirejection drugs
"The story of Ms. Whitaker’s two organ donations — the first from her mother and the second from her boyfriend — sheds light on a Medicare policy that is widely regarded as pound-foolish. Although the government regularly pays $100,000 or more for kidney transplants, it stops paying for anti-rejection drugs after only 36 months."...
"Most of the cost of [her] dialysis and the transplant, totaling hundreds of thousands of dollars, was absorbed by the federal Medicare program, which provides broad coverage for those with end-stage renal disease.
Despite that heavy investment, federal law limits Medicare reimbursement for the immunosuppressant drugs that transplant recipients must take for life, at costs of $1,000 to $3,000 a month."...
"By late 2003, her transplanted kidney had failed, and she returned to dialysis, covered by the government at $9,300 a month, more than three times the cost of the pills. Then 15 months ago, Medicare paid for her second transplant — total charges, $125,000 — and the 36-month clock began ticking again.
“If they had just paid for the pills, I’d still have my kidney,” said Ms. Whitaker, who shares an apartment in the La Jolla neighborhood with her boyfriend, Joseph D. Jamieson. “I’d be healthy, working and paying taxes.” "...
"Bills have been introduced in Congress since 2000 to lift the 36-month limit and extend coverage of immunosuppressant drugs indefinitely. They have never made it to a vote, largely because of the projected upfront cost; the Congressional Budget Office estimates that unlimited coverage would add $100 million a year to the $23 billion Medicare kidney program.
But the cost-benefit analysis would seem obvious. The most recent report from the United States Renal Data System found that Medicare spends an average of $17,000 a year on care for kidney transplant recipients, most of it for anti-rejection drugs. That compares with $71,000 a year for dialysis patients and $106,000 for a transplant (including the first year of monitoring)...."
"A provision to cover the drugs is in the sweeping House health care bill, which has cleared three committees. It is uncertain whether the Senate Finance Committee will include it in its bill.
Since 1973, end-stage renal disease has been the only condition specifically covered by Medicare regardless of age. In 1988, coverage was extended for 12 months to anti-rejection drugs, which had recently been developed. Congress gradually lengthened the cutoff to 36 months, and then in 2000 made the benefit unlimited for those who are at least 65 or disabled. The rationale for leaving out younger transplant recipients was simply that the money was not there, Congressional aides said. "
In other kidney news, I understand through the grapevine that the planned September pilot of a national kidney exchange program to be conducted by UNOS has been put on hold for the time being.

Your penny for my two cents: micropayments on the web
Harvard's Neiman Journalism Lab reports on Google's marketplace proposal, which would allow customers to maintain a Google account that could be billed without requiring the customer to maintain accounts or reveal information to each content provider: Google developing a micropayment platform and pitching newspapers: “‘Open’ need not mean free”
Authors' Registry: Clearinghouse for small payments
How should small fees for copying copyrighted material be collected and distributed? About once a year, I get a communication from The Authors Registry , which works to find authors on whose behalf such fees--presumably collected by the penny in copyshops and libraries--have been collected.
"The Authors Registry is a not-for-profit clearinghouse for payments to authors, receiving royalties from organizations and distributing them to U.S. authors. It was founded in 1995 by a consortium of U.S. authors' organizations: The Authors Guild, The American Society of Journalists & Authors, the Dramatists Guild, and the Association of Authors' Representatives. To date, the Authors Registry has distributed over $8,000,000 to authors in the United States."
They seem to be closely affiliated with the Authors' Licensing & Collecting Society (UK).
"The Authors’ Licensing and Collecting Society (ALCS) represents the interests of all UK writers and aims to ensure writers are fairly compensated for any works that are copied, broadcast or recorded. Writers’ primary rights are protected by contract, but it is the life of the work over the following decades that needs to be monitored and fairly rewarded. It is with secondary rights that copyright has an important role to play in protecting writers and creators from unpaid use and moral abuse of their work. Secondary use ranges from photocopying and repeat broadcast transmission in the UK and overseas to reproduction in journals and repeat use via the internet and digital reproduction."
"Photocopying of books and serials currently accounts for approximately 70% of income. The ALCS together with the Publishers Licensing Society (PLS) has appointed the Copyright Licensing Agency (CLA) to act as its agent to license the photocopying right on its behalf and on behalf of its members on a non-exclusive basis. A small number of CLA licences now include the authority for limited scanning. Public Lending Right ALCS administers German, Austrian, Dutch and French Public Lending Right (PLR) for UK authors, and is in the process of entering into agreements with other European countries where PLR is being incorporated in to national legislation. UK PLR is administered by Public Lending Right based in Stockton-upon-Tees and funded by the Department of Culture, Media and Sport (DCMS). "
The collections are quite small; e.g. my recent statement, which seems to originate in the ALCS looks like this:
PHOTOCOPYING - OVERSEAS Miscellaneous CLA Monies - Inside EU 1.02
NON TITLE SPECIFIC Miscellaneous CLA Monies - UK 40.03
PHOTOCOPYING - OVERSEAS Miscellaneous CLA Monies - Outside EU 15.52
SUBVENTION ON ACCOUNT Miscellaneous CLA Photocopying Fees 7.97
PLS Balancing Payment General CLA Photocopying Fees 2007 - 2008 34.56

Norman Borlaug, father of "Green Revolution"
"By the late 1940s, researchers knew they could induce huge yield gains in wheat by feeding the plants chemical fertilizer that supplied them with extra nitrogen, a shortage of which was the biggest constraint on plant growth. But the strategy had a severe limitation: beyond a certain level of fertilizer, the seed heads containing wheat grains would grow so large and heavy, the plant would fall over, ruining the crop.
In 1953, Dr. Borlaug began working with a wheat strain containing an unusual gene. It had the effect of shrinking the wheat plant, creating a stubby, compact variety. Yet crucially, the seed heads did not shrink, meaning a small plant could still produce a large amount of wheat.
Dr. Borlaug and his team transferred the gene into tropical wheats. When high fertilizer levels were applied to these new “semidwarf” plants, the results were nothing short of astonishing.
The plants would produce enormous heads of grain, yet their stiff, short bodies could support the weight without falling over. On the same amount of land, wheat output could be tripled or quadrupled. Later, the idea was applied to rice, the staple crop for nearly half the world’s population, with yields jumping several-fold compared with some traditional varieties.
This strange principle of increasing yields by shrinking plants was the central insight of the Green Revolution, and its impact was enormous."
People are experience goods (online dating version)
Frost, Jeana H., Zoe Chance, Michael I. Norton, and Dan Ariely. People Are Experience Goods: Improving Online Dating with Virtual Dates. Journal of Interactive Marketing 22, no. 1 (winter 2008): 51-62.
Abstract: "We suggest that online dating frequently fails to meet user expectations because people, unlike many commodities available for purchase online, are experience goods: Daters wish to screen potential romantic partners by experiential attributes (such as sense of humor or rapport), but online dating Web sites force them to screen by searchable attributes (such as income or religion). We demonstrate that people spend too much time searching for options online for too little payoff in offline dates (Study 1), in part because users desire information about experiential attributes, but online dating Web sites contain primarily searchable attributes (Study 2). Finally, we introduce and beta test the Virtual Date, offering potential dating partners the opportunity to acquire experiential information by exploring a virtual environment in interactions analogous to real first dates (such as going to a museum), an online intervention that led to greater liking after offline meetings (Study 3)."
Marriage and dating in NYC: matching complements
"The invitation to the latest Fashion Meets Finance party — an affair that shamelessly includes only women who work in fashion and men from Wall Street — declared that the dark days are over — not just for the economy, but in the dating market. “We are here to announce the balance is restoring itself to the ecosystem of the New York dating community,” the party organizers said on their cheeky Web site."
...
"“From my experience, I’ve dated lawyers and doctors and they’re nice; I just prefer finance,” Ms. Yanush said, before applying a fresh gloss of candy-apple-red lipstick in the ladies room. “My girlfriends who are in long-term relationships with finance guys are very happy.” "
...
"The idea behind Fashion Meets Finance began in 2007 with Beth Newill, a merchandiser for Ann Taylor at the time, who found the garment district was a poor neighborhood in which to meet men. After speaking with a male friend who worked in finance and had expressed the same frustration about the absence of eligible women in the financial district, Ms. Newill organized regular happy hours for the two groups."
...
"The text with the latest invitation, the first party since January, was typical: “We fear that news of shrinking bonuses, banks closing and the Dow plummeting confused the gorgeous women of the city who understood that their shelf life is quick and fleeting like a senator’s South American love affair. The uncertainty caused panic which caused irrational decisions — there’s going to be a two-year blip in the system where a hot fashion girl might commit to a pharmaceutical salesman.”
The women were encouraged to hold on because the recession is over, and it would only be a matter of time before a boyfriend in finance enabled them to quit their jobs to be “tennis moms.”
Jeremy Abelson, 29, the founder of an online luxury newsletter called Pocket Change, who creates most of the Web site’s copy, said, “It’s offensive but it’s very realistic.” "
The article closes by quoting someone who didn't meet the woman of his dreams: "“Let’s just say I’m not going to find my future ex-wife here,” he said."

Debtor's prison in Dubai
Here's what I wrote about debtor's prison, in Repugnance as a Constraint on Markets:
"The changing repugnance of debt and of involuntary servitude have even interacted in changes to bankruptcy law. In colonial America and the early years of the Republic, insolvent debtors could be imprisoned, or sentenced to indentured servitude (Coleman, 1974 [1999]). But as involuntary servitude became more repugnant and debts less repugnant, bankruptcy laws were rewritten to be less punitive to debtors."(p. 40)
Service versus self service
The recent decisions by some universities to manage their shortage of central-campus parking has raised some eyebrows:
Recession? Valet Parking Arrives.
And, indeed, that story makes it sound as if some of the parking decisions are meant to increase customer service where there's a shortage of conveniently located parking.
That being said, it's often more convenient to be able to park yourself rather than have to rely on someone else. But parking lots (and, in Manhattan, multi-story garages served by car elevators) in which the attendants park all the cars allow more cars to be accomodated in a given amount of space. It may be a luxury to leave your car for someone else to park, but it's seldom a luxury to wait while your car is brought out of parking.
Years ago, a colleague from Brazil remarked that one thing she liked about living in the United States was that she didn't have to deal with servants. I foolishly asked why in that case she couldn't just dispense with servants when she was in Brazil. The answer of course was that many things that are designed for self service here are more labor intensive there. I recall that one example was that chicken is sold shrink-wrapped and ready to cook in American supermarkets, but was apparently sold with pinfeathers still attached in Brazil (in those days).

Two-career job searches
The Chronicle of Higher Ed has a first person account of one such struggle, that ended successfully with two tenure-track assistant professorships at the same university: Lessons of a Dual Hire.
The (pseudonymous) author writes:"After three years of job searching for me in the geological sciences, and four years for my husband in engineering, we successfully maneuvered this year to find two tenure-track positions at the same university. Here's how it happened."
The article goes on to explain some of the difficulties that were overcome in the most recent, successful job search.
Here are two earlier related posts, both of which touch on my work on making the clearinghouse for new doctors, the National Resident Matching Program, more friendly to couples.
Job market for couples (which concerns law schools hiring of couples); and
Match Day for new doctors, which is specifically about couples who are both seeking jobs as new doctors.
Even the medical clearinghouse doesn't do much to help doctors whose spouses have non-medical careers (or even doctors whose spouses have medical careers with different years of graduation from medical school). Some years ago, I was asked to respond to an essay from a doctor's spouse which suggested that maybe the market would work better without a match, i.e. without any centralized clearinghouse. That essay, and my reply, were published in an online student edition of JAMA that no longer exists, on web pages that are no longer maintained. However I am linking to them below, on the remarkable internet archive also known as the Wayback Machine.

Law clerks for Massachusetts courts, continued
"The state judiciary has abandoned a controversial proposal to fill coveted law clerk jobs at no cost to the government with newly hired private lawyers whose firms have pushed back their start dates because of the recession."
...
"Mulligan had proposed the arrangement in the spring because of two related employment trends. Tight finances had forced the state to rescind job offers it had made in December to at least 24 recent law school graduates who wanted to work as law clerks. And the bad economy had prompted some law firms to defer bringing on first-year associates at full salaries.
Many firms around the country are paying such “deferred associates’’ stipends of about $60,000, less than half their regular starting salaries of about $150,000, to hold onto them until the economy improves.
Some firms have recommended that the fledgling lawyers volunteer at nonprofit groups or engage in public service. And several local firms asked Mulligan whether their associates in waiting could perform their public service as law clerks.
Some legal specialists had said an arrangement that involves a law firm paying a judicial employee raised thorny ethical questions; firms that donate lawyers to the courts might appear to be currying favor or expect preferential treatment.
...
"But Mulligan won the approval of the Committee on Judicial Ethics of the Supreme Judicial Court after he proposed a special “double blind’’ arrangement.
The Flaschner Judicial Institute, which provides continuing education to state judges, would have dealt with the law firms that supplied the clerks. Judges and court officials would have had no contact with the donating firms, and the firms would have been instructed not to identify the clerks on their websites. The clerks would have been barred from disclosing which firms were paying their stipends."
Here is my earlier post on the proposal: Law clerks for Massachusetts courts
