Black markets in everything bagels (in S. Korea)

 South Korea is not a hub of everything bagels, it turns out. In fact they are banned.

The NYT has the story:

Why Everything Bagel Seasoning Was Banned in South Korea. The seasoning is sold by Trader Joe’s, a brand whose popularity has skyrocketed in the region in recent years.By Eve Sampson

"Food containing poppy seeds, “including popular bagel seasoning blends,” is considered contraband in South Korea, according to the U.S. Embassy, making the coveted topping a forbidden treat.

...

"As more travelers have tried to bring the popular seasoning mix into South Korea, local news and social media sites have reported in recent weeks on an increase in confiscations at airports.

"Poppy seeds are not opiates but may be contaminated by the plant’s fluid, which contains opiates, when they are harvested. 

...

"In South Korea, poppy seeds are banned because they are considered a narcotic.

...

"South Korea is among the few countries with laws regulating poppy seeds. The United Arab Emirates bans the seed, and Singapore requires anyone wishing to import poppy seeds to submit a sample for opiate testing.

"In the United States, there has also been mixed messaging about poppy seeds. In 2023, the Department of Defense warned members of the military that eating poppy seeds could result in a positive drug test, despite the military previously feeding service members poppy seed breads in ready-to-eat meals."

It's against the law in North Korea to use South Korean words

 From Radio Free Asia:

North Korea sentences 20 young athletes for ‘speaking like South Koreans’. Skaters and skiers were caught on video using banned words while playing a game during training.  By Jieun Kim for RFA Korean

"About 20 aspiring North Korean winter athletes were abruptly sentenced to three to five years of hard labor in prison camps after they were found to have used South Korean vocabulary and slang while playing a word game, sources in the country say.

"It’s the latest example of authorities imposing draconian punishments to try to stamp out use of the “puppet language” and “capitalist” influences in daily life – despite the flood of illegal South Korean dramas and songs that many North Koreans secretly watch after obtaining them on thumb drives smuggled into the country.

"The ice skaters and skiers, all high school graduates under the age of 25 from Ryanggang province, were publicly disgraced at a square in Hyesan on April 3, a resident in the city on the Chinese border told Radio Free Asia’s Korean Service on condition of anonymity for security reasons.

“Residents think that it is excessive that they were sentenced between three and five years” of hard labor, another source in the city said. “It would be impossible to count how many hundreds or thousands of South Korean movies and dramas are easily available to us.”

...

"Apparently, one of the athletes took a video of the young people playing a word game called mal kkori itgi, where the object is to make a sentence that starts with the final word of the previous player’s sentence, and some of the athletes used vocabulary that was distinctly South Korean, a second source from the same province said.

"The video was found on the phone of one of the female athletes during a random inspection raid by police of her home – a frequent occurrence in North Korea when police look for contraband – and was reported to authorities. It wasn’t clear if she had taken the video or if it was sent to her, the first source said.

...

"The North Korean government recently passed the Pyongyang Cultural Language Protection Act, which underscores that the Pyongyang dialect is the standard language, and doles out severe punishments for speaking like a South Korean, or the death penalty for teaching others how to."

Black market tattoos in S. Korea: “No one’s trying to go to medical school to become a tattoo artist,”

 Tattooing is illegal (but tattoos are not) in S. Korea.  The NY Times has the story:

Tattoos, Still Illegal in South Korea, Thrive Underground. Tattoo artists, long treated as criminals for their work, say that it is time to end the stigma against their business.  By Christine Chung

"Under a ruling that has been in place since 1992, tattooing without a medical license can result in fines of up to $40,000 or even imprisonment. Opponents of decorative tattoos have invoked concerns about longstanding associations with organized crime, as well as fears about inadequate hygiene and potential harm inflicted by tattoo artists, who they say lack adequate skills.

"Attempts to overturn this ban have repeatedly failed. In March, the Constitutional Court in Seoul reaffirmed the tattoo industry’s illegality in a 5-to-4 ruling. South Korean tattoo artists and customers believe that the ruling is at odds with reality, citing drastically changed social norms that have fostered a thriving underground industry, greater openness and acceptance of tattoos, and rising international demand for what are known as “k-tattoos.”

"While tattoos have grown in acceptance in most parts of the world — exceptions include several Islamic countries — South Korea remains one of the few where the artists are treated as criminals. Tens of thousands of them work in secret here, under constant threat of exposure to law enforcement.

...

“No one’s trying to go to medical school to become a tattoo artist,” she said.

...

"Mr. Kim is the founder of a 650-member tattoo labor union that advocates rights of artists. Legalization would create safer, more sanitary environments for both customers and artists, he said.

"Tattoo artists often meet clients alone and trust strangers to keep their secret. Female artists are particularly vulnerable to sexual violence. In the past, the police have conducted sweeps rounding up artists, Sanlee said. Rival shops have been known to flag artists to the police.

“Since what we’re doing is illegal, we’re in the blind spot,” she said. “Because of that, there are many people that are exploiting the situation.”

Repugnance watch: Dog (as) food in Korea--opposition from the President, amidst growing pet ownership

 Here's the story from the Guardian:

South Korean president suggests ban on eating dog meat. Moon Jae-in, a dog-lover, says ‘time has come’ for traditional practice to end. 

"The South Korean president, Moon Jae-in, has raised banning the eating of dogs in the country, his office said, a traditional practice that is becoming an international embarrassment.

"The meat has long been a part of South Korean cuisine with about 1 million dogs believed to be eaten annually, but consumption has declined as more people embrace the animals as companions rather than livestock.

"The practice is something of a taboo among younger generations and pressure from animal rights activists has been mounting.

“Hasn’t the time come to prudently consider prohibiting dog meat consumption?” Moon asked the prime minister, Kim Boo-kyum, during a weekly meeting on Monday, according to the presidential spokesperson."

**************

And from the Washington Post:

South Korea considers ban on eating dog meat as pet ownership grows in the country  By Grace Moon  and Andrew Jeong

 "South Korea is considering a ban on dog meat consumption, officials said Tuesday, a day after President Moon Jae-in ordered the government to explore such a move.

"The news comes after years of public outcries against the roughly 3,000 dog farms still operating in South Korea. Animal rights activists have accused the farmers of holding dogs in horrid conditions.

"Criticism surrounding the consumption of dog meat has grown as more South Koreans adopt canine pets: About 27 percent of South Korean homes have pets, with the majority of them being dogs — up from 17 percent in 2010 — according to the agriculture ministry. (About half of American households reported having pets in 2018, according to the Census Bureau and Simmons National Consumer Study.)"

A non-simultaneous liver exchange chain at UCSF, and a brief history of liver exchange

 Living donor liver transplants are relatively uncommon in North America compared to Asia.  Liver exchange might help change that. Here are some reports of recent and not so recent liver exchanges, including a non-simultaneous exchange chain  at UCSF, and a simultaneous chain in Canada.  Expect more in the near future.

 (Non-simultaneous chains have become the backbone of kidney exchange in the U.S., so we may start to see longer chains of liver exchange as well.)

Here's the most recent report of a short non-directed donor chain:

Expanding living donor liver transplantation: Report of first US living donor liver transplant chain  by Hillary J. Braun  Ana M. Torres  Finesse Louie  Sandra D. Weinberg  Sang‐Mo Kang  Nancy L. Ascher  John P. Roberts, American Journal of Transplantation, First published: 10 November 2020 https://doi.org/10.1111/ajt.16396

Abstract: "Living donor liver transplantation (LDLT) enjoys widespread use in Asia, but remains limited to a handful of centers in North America and comprises only 5% of liver transplants performed in the United States. In contrast, living donor kidney transplantation is used frequently in the United States, and has evolved to commonly include paired exchanges, particularly for ABO‐incompatible pairs. Liver paired exchange (LPE) has been utilized in Asia, and was recently reported in Canada; here we report the first LPE performed in the United States, and the first LPE to be performed on consecutive days. The LPE performed at our institution was initiated by a nondirected donor who enabled the exchange for an ABO‐incompatible pair, and the final recipient was selected from our deceased donor waitlist. The exchange was performed over the course of 2 consecutive days, and relied on the use and compliance of a bridge donor. Here, we show that LPE is feasible at centers with significant LDLT experience and affords an opportunity to expand LDLT in cases of ABO incompatibility or when nondirected donors arise. To our knowledge, this represents the first exchange of its kind in the United States."

The paper says this about the timing of the surgeries:

"Other centers reporting LPE have performed the donor and recipient operations in four operating rooms simultaneously4, 5 which can be logistically challenging, but addresses concerns regarding simultaneity and equalizing risk. In our case, we performed the operations on sequential days. In doing so, we accepted the risk that, given a good outcome in Recipient 1 on the first day, Donor 2 (the “bridge” donor) might opt out of living donation at the last moment. Reappropriating terminology from the kidney paired exchange (KPE) literature, a bridge donor is defined as someone who donates more than 1 day after their intended recipient received a transplant.12 A recent paper discussing the feasibility of LPE in the United States emphasized that, in the early days of KPE, there was concern that the bridge donor might back out at the last minute and break the chain.13 As a result, kidney donor operations were initially attempted simultaneously. However, a 2018 review of 344 KPE chains between 2008 and 2016 revealed that only 5.6% of bridge donors broke the chain and the majority of these donors developed a medical issue during their time as a bridge donor that prohibited them from completing donation.12 Ultimately, because this occurrence was so infrequent, the authors concluded that simultaneous donor operating rooms for chains are unnecessary and may actually deter potential donors based on logistical issues. "

And here's a report from Canada of a non-directed donor chain of liver exchange with all surgeries conducted simultaneously (also with the NDD donating to an incompatible patient-donor pair whose donor donated to a patient on the deceased donor waiting list).

Living donor liver paired exchange: A North American first  by Madhukar S. Patel  Zubaida Mohamed  Anand Ghanekar  Gonzalo Sapisochin  Ian McGilvray  Blayne A. Sayed  Trevor Reichman  Markus Selzner  Jed A. Gross  Zita Galvin  Mamatha Bhat  Les Lilly  Mark Cattral  Nazia Selzner, American Journal of Transplantation, First published: 10 June 2020 https://doi.org/10.1111/ajt.16137 

Abstract: Paired organ exchange can be used to circumvent living donor‐recipient ABO incompatibilities. Herein, we present the first case of successful liver paired exchange in North America. This 2‐way swap required 4 simultaneous operations: 2 living donor hepatectomies and 2 living donor liver transplants. A nondirected anonymous living donor gift initiated this domino exchange, alleviating an ABO incompatibility in the other donor‐recipient pair. With careful attention to ethical and logistical issues, paired liver exchange is a feasible option to expand the donor pool for incompatible living liver donor‐recipient pairs.

Update on Experience in Paired-Exchange Donors in Living Donor Liver Transplantation For Adult Patients at ASAN Medical Center by  Jung, Dong-Hwan1; Hwang, Shin1; Ahn, Chul-Soo1; Kim, Ki-Hun1; Moon, Deok-Bog1; Ha, Tae-Yong1; Song, Gi-Won1; Park, Gil-Chun1; Lee, Sung-Gyu, Transplantation: April 27, 2014 - Volume 97 - Issue - p S66-S69, doi: 10.1097/01.tp.0000446280.81922.bb

"Between January 2003 and December 2011, approximately 2,182 adult LDLT cases were included in this study. During this period, 26 paired-exchange donor LDLT cases were performed (1.2%).

"Results: Of the 26 paired-exchange donor LDLT cases, 22 pairs were matched due to ABO-incompatibility, and 4 pairs were matched because of cascade allocation of unrelated donors or relatively small graft volume to the recipients. A total of 28 living donors were included in the 26 paired-exchange donor LDLT cases because of inclusion of two dual-graft transplants. Elective surgery was performed in 22 cases, and urgent operation was performed in 4 cases. The overall 1-year and 5-year patient and graft survivals were both 96.2% and 90.1%, respectively.

"Conclusions : Our experience suggests that the paired-exchange donor program for adult LDLT seems to be a feasible modality to overcome donor ABO incompatibility."

Where man's best friend also tastes good: the market for dog meat in Korea

The winter Olympics in Korea is bringing out stories about the restaurants there that have dog meat on the menu, and about how foreigners might not be charmed:

The Daily Mail headlines it this way (with lots of pictures):
The trade in dog meat South Korea doesn't want Olympics tourists to see is exposed at market where they are slaughtered, chopped up and served in bubbling red broth for just $8 a bowl
Here are their sub-headlines

• "Dogs and even puppies are sold openly for food in Moran market, Seongnam, outside of Seoul, South Korea, Dailymail.com reveals - showing claims it would be closed last May are false 
• The dogs are kept in freezing, dark cages until they are slaughtered, their fur burned off and their carcasses are put on display
• Up to 80,000 dogs are sold and slaughtered at the market a each year to be made into an $8 soup, which folklore claims boosts eaters' sex drive 
• But ahead of the Olympic Winter Games coming to PyeongChang on Friday, officials issued guidelines for when it comes to eating dog meat, urging citizens not to consume the animals during the Olympics 
• Two-month-old puppies fare little better, being sold for just $9.20 or £6.50 out of metal crates and cardboard boxes, with some saying they can be eaten too "

USA Today puts it this way:
Winter Olympics shines spotlight on dog meat trade in South Korea

"Eating dog meat is common and legal in Korea, as well as many parts of Asia, and is mainly eaten by older people. Dotted around the country are thousands of restaurants serving “gaegogi” dishes that, according to folklore, have strengthening and medicinal properties."

College Admissions as Non-Price Competition: The Case of South Korea

Chris Avery and Soo Lee and I have a new NBER working paper:

College Admissions as Non-Price Competition: The Case of South Korea

Christopher Avery, Alvin E. Roth, Soohyung Lee

NBER Working Paper No. 20774
Issued in December 2014
NBER Program(s):   ED 

This paper examines non-price competition among colleges to attract highly qualified students, exploiting the South Korean setting where the national government sets rules governing applications. We identify some basic facts about the behavior of colleges before and after a 1994 policy change that changed the timing of the national college entrance exam and introduced early admissions, and propose a game-theoretic model that matches those facts. When applications reveal information about students that is of common interest to all colleges, lower-ranked colleges can gain in competition with higher-ranked colleges by limiting the number of possible applications.

Brides "for sale:" marriage patterns in East Asia

Soohyung Lee and Daiji Kawaguchi have a paper on marriage and matching that looks at who marries whom in East Asia.  As I understand it, they argue that there's a powerful norm there for men to "marry down," (related to having "traditional" expectations of marriage) with the result that highly educated women and poorly educated men have difficulty finding suitable local spouses, and that the lower educated men marry foreign brides from poorer countries.

Brides for Sale: Cross-Border Marriages and Female Immigration

Abstract: Every year, a large number of women migrate as brides from developing countries to developed countries in East Asia. This phenomenon virtually did not exist in the early 1990s, but foreign brides currently comprise 4 to 35 percent of newlyweds in these developed Asian countries. This paper argues that two factors account for this rapid increase in “bride importation”: the rapid growth of women's educational attainment and a cultural norm that leads to low net surplus of marriage for educated women. We provide empirical evidence supporting our theoretical model and its implications, using datasets from Japan, Korea, Taiwan, and Singapore.

Kidney Exchange in South Korea

S. Korea was a pioneer in kidney exchange. (In the U.S. population, Asians have the highest frequency of blood type B, almost equal to their frequency of A, and so the simplest exchanges of an A-B patient donor pair with a B-A patient donor pair come up more often among Asians.)

Here's a report of their experience.

Exchange Living-donor Kidney Transplantation: The Present and Future. Huh KH, Kim YS, Kim BS. Department of Surgery, Yonsei University College of Medicine, Korea. yukim@yuhs.ac Department of Internal Medicine, Yonsei University College of Medicine, Korea. Abstract The shortage of donor organs is one of the major barriers of transplantation worldwide. After the success of the direct exchange donor (swap) program in Korea since 1991, a swaparound program has been developed. Recently, a web-based (computerized) algorithm to facilitate donor kidney exchange was devised and tested in multi-center settings. An excellent longterm outcome was achieved by using the donor exchange program as an option to reduce the donor organ shortage. Herein, we discussed on the current status of the exchange donor renal transplantation in Korea, a couple of problems we have had, and future directions we have to head and make better to improve organ donation activities.

Liver exchange

Living Donor Exchange Poses New Option for Liver Transplantation "Two major transplant centers in Hong Kong and South Korea released results from their paired donor exchange programs for living donor liver transplantation (LDLT). A single paired exchange, performed by the Hong Kong team under emergency circumstances, was a success. The Korean team reported 16 donor exchanges conducted over a 6-year period were successful. Full details of this novel approach to organ transplantation appear in the April issue of Liver Transplantation."

And here are the two papers and abstracts: 

  Paired Donor Interchange to Avoid ABOIncompatible Living Donor Liver Transplantation, by See Ching Chan, Chung Mau Lo, Boon Hun Yong, Wilson J. C. Tsui, Kelvin K. C. Ng, and Sheung Tat Fan, Queen Mary Hospital, University of Hong Kong, Hong Kong, China 

"We report an emergency paired donor interchange living donor liver transplant performed on January 13, 2009. The 4 operations (2 liver transplants) were performed simultaneously. The aim was to avoid 2 ABO-incompatible liver transplants. One recipient in acute liver failure underwent transplantation in a high-urgency situation. The abdomen of the other recipient had severe adhesions from previous spontaneous bacterial peritonitis that rendered the recipient operation almost impossible. The ethical and logistical issues are discussed. Approaches adopted in anticipation of potential adverse outcomes are explained in view of the higher donor and recipient mortality and morbidity rates in comparison with kidney transplantation."

"ABO incompatibility is the most common cause of donor rejection during the initial screening of adult patients with end-stage liver disease for living donor liver transplantation (LDLT). A paired donor exchange program was initiated to cope with this problem without ABO-incompatible LDLT. We present our results from the first 6 years of this exchange adult LDLT program. Between July 2003 and June 2009, 1351 adult LDLT procedures, including 16 donor exchanges and 7 ABO-incompatible LDLT procedures, were performed at our institution. Initial donor-recipient ABO incompatibilities included 6 A to B incompatibilities, 6 B to A incompatibilities, 1 A to O incompatibility, 1 A+O (dual graft) to B incompatibility, 1 O to AB incompatibility, and 1 O to A incompatibility. Fourteen matches (87.5%) were ABO incompatible, but 2 (12.5%) were initially ABO-compatible. All ABO-incompatible donors were directly related to their recipients, but 2 compatible donors were each undirected and unrelated directed. After donor reassignment through paired exchange (n = 7) or domino pairing (n = 1), the donor-recipient ABO status changed to A to A in 6, B to B in 6, O to O in 1, A to AB in 1, A+O to A in 1, and O to B in 1, and this made all matches ABO identical (n = 13) or ABO-compatible (n = 3). Two pairs of LDLT operations were performed simultaneously on an elective basis in 12 and on an emergency basis in 4. All donors recovered uneventfully. Fifteen of the 16 recipients survived, but 1 died after 54 days. In conclusion, an exchange donor program for adult LDLT appears to be a feasible modality for overcoming donor-recipient ABO incompatibility."Liver Transpl 16:482-490, 2010. V

Marriage and dating online in Korea

Soohyung Lee has a paper about an online marriage market in Korea, whose findings are similar in some respects to those in the papers described in my two earlier posts today, and different in others: Preferences and Choice Constraints in Marital Sorting: Evidence From Korea.

Like the paper by Hitsch, Hortaçsu, and Ariely, Lee's paper considers detailed transactional data from an online site, this one aimed at marriage rather than more casual dating, and uses the data to estimate preferences for mates, based on a variety of observable traits. Like both Hitsch et al. and the paper on Indian marriages by Banerjee, Duflo, Ghatak and Lafortune, Lee's paper looks at stable matches produced by a deferred acceptance algorithm based on the estimated preferences, and compares them to the observed marriages in population data. Unlike those two papers, the findings in Korea are that the simulated stable matchings look different than the population matchings; they are less assortative on some dimensions (such as employment in the same industry).

The paper suggests that some aspects of Korean marriage data therefore reflect choice constraints on who meets whom, and that as these constraints are relaxed (perhaps by increased use of internet matchmaking), some aspects of Korean life may change.

Market design update (5/12/09): Professor Lee sends me the following email describing how her work has proved useful in the design of the matching site, which uses an algorithm to suggest several possible dates to each participant:
"FYI, the matchmaking company partially adopted my estimates to adjust its matching algorithm. Previously, it assumed all men and all women have the same preference ranking. Under the revised algorithm, it classifies men and women based on their characteristics and allows them to have heterogeneous preference rankings (which I find in my estimation).
With the revised algorithm, the company was able to increase the probability of a proposal turning into an actual first date by a factor of 2. "
