Some ASSA sessions I would go to if I could, and some I'll certainly attend

I'm going to be a busy boy at the AEA/ASSA meetings, since as president of the AEA I'll preside over many champagne receptions and a few other things.  But the conference looks like fun. Here are just a few of the sessions that particularly caught my eye, even though I have conflicts with some of them...

    Change in Swedish law about sexual assault

    From The Guardian:
    Swedish rape law would require explicit consent before sexual contact

    "Sweden is moving closer to making changes to its rape laws that would require people to get explicit consent before sexual contact.
    ...
    "Under current Swedish law someone can be prosecuted for rape only if it has been proved that they used threats or violence. Under the proposal, rape could be proved if the accuser hadn’t given their explicit verbal agreement or clearly demonstrate their desire to engage in sexual activity.
    ...
    "The proposal is part of a series of initiatives being put forward. Others would make it illegal for Swedes to hire prostitutes abroad, and increase sentences for offenders. Buying sex in Sweden is already illegal."

    Opioids and harm reduction: drug checking and Safe Injection Facilities

    From Mason Marks writing on the Bill of Health blog at Harvard Law School:


    The Opioid Crisis Requires Evidence-Based Solutions, Part III: How the President’s Commission on Combating Drug Addiction Dismissed Harm Reduction Strategies

    " it is noteworthy that the Commission ignored harm reduction strategies such as drug checking, which could reduce deaths due to consumption of contaminated opioids. Many countries including Austria, Belgium, Switzerland, Portugal, Spain, Switzerland, and the Netherlands offer free and confidential drug checking (also known as pill testing) to drug users. Drug checking could reduce consumption of adulterated drugs and provides opportunities to support and counsel users who may otherwise receive no contact with medical or public health professionals. Drug checking is also a valuable source of information about drug use such as pricing, availability, effects, and composition of street drugs. This information can be used to further our understanding of drug use and its effects.
    Some experts argue that drug dealers will be less likely to add dangerous adulterants to their products if they know that consumers have a mechanism to test their contents. The identification of drug contents can alert authorities to the presence of synthetic opioids, which can lead to public warnings and announcements that may further drive dealers to withdraw deadly additives from the market. The practice can also improve law enforcement efforts to reduce the illegal importation and sale of synthetic opioids. Dr. Carl Hart, Chair of the Department of Psychology at Columbia University, supports the use of free and anonymous drug checking in the United States. In a Scientific American article, heargues that the opioid crisis is a distinctly American problem. According to Hart, “Throughout Europe and other regions where opioids are readily available, people are not dying at comparable rates as those in the U.S., largely because addiction is not treated as a crime but as a public health problem.” Drug checking is one example of how European countries approach drug abuse from a public health angle rather than a punitive law enforcement perspective.
    Critics of drug checking argue that it could normalize drug use or “send the wrong message” to potential users. For instance, the practice could create the appearance of safety when in fact the drugs being consumed are dangerous. ...
    "Supervised injection facilities (SIFs), arguably a more controversial option than drug checking, were also ignored by the President’s Opioid Commission. SIFs provide a place for people to inject drugs under professional supervision to minimize the risk of HIV and hepatitis C infection, drug overdose, and death. They are primarily used in Switzerland, Canada, and Australia. However, the City of Denver is taking steps to become the first U.S. city to offer SIFs. In November, a plan for a pilot program won unanimous approval from a bipartisan ten-member legislative committee. However, the City’s General Assembly must approve the plan in January 2018 for it to move forward. Seattle and San Francisco are considering similar proposals. The State of Vermont is also considering using SIFs. On November 29, 2017, a commission of health and law enforcement professionals, led by State’s Attorney General Sarah George, recommended that Vermont make SIFs a part of its opioid strategy. However, the Vermont Commissioner of Public Safety and the Vermont Association of Police Chiefs disagree. The Commissioner stated, “Facilitating the ongoing use of heroin through SIFs sends the wrong message, at the wrong time, to the wrong people.”
    ...
    "A 2014 review published in the journal Drug and Alcohol Dependence, examined the outcome of 75 studies and concluded that SIFs are an effective harm-reduction strategy not associated with increased drug use or crime. In early 2017, the Massachusetts Medical Society published its analysis of SIFs. It found that peer-reviewed research published in leading academic journals, such as JAMA and the New England Journal of Medicine, supports the conclusion that SIFs produce positive outcomes such as reduced mortality and increased access to drug treatment.
    ...
    "Admittedly, there could be an “ick factor” associated with SIFs, and overly zealous drug control advocates could find them repugnant. However, when thousands of lives are at stake, emotional reactions to SIFs must be weighed against the scientific evidence. If the evidence suggests that SIFs are effective, then lawmakers must be courageous and allow their decisions to be guided by science rather than emotions such as disgust."

    Is there an equivalence between (not) paying kidney donors and boxers or football players?

    Kim Krawiecz makes a point, in several installments:

    December 21, 2017
    If You Oppose Paying Kidney Donors, You Should Oppose Paying Football Players And Boxers Too 
    "Having concluded that simply advocating for compensated kidney donation was not sufficiently controversial, Phil Cook and I are now turning our sights on professional sports – specifically, professional football and boxing. In a piece just posted to SSRN, we contrast the compensation ban on organ donation with the legal treatment of football, boxing, and other violent sports in which both acute and chronic injuries to participants are common. While there is some debate about how best to regulate these sports in order to reduce the risks, there appears to be no serious debate about whether participants should be paid. Indeed, for the best adult football players, college scholarships and perhaps a professional contract worth multiple millions are possible."


    December 22, 2017
    Paying Kidney Donors, Football Players, And Boxers: Medical Risks
    "the medical risks to a professional career in football, boxing, and other violent sports are much greater both in the near and long term than the risks of donating a kidney. Injuries in such sports are common, and retired players are very often disabled by the long-term effects of these injuries as well the cumulative effect of thousands of blows to the body."

    December 24, 2017
    Paying Kidney Donors, Football Players, And Boxers: Informed Consent And It’s Limits
    "We believe that if NOTA were amended to allow payments to donors, potential kidney donors could be protected against being unduly tempted through the existing structure of screening, counseling, and delay, perhaps with some additional protections to prevent hasty decisions. On the other hand, it is not clear that NFL recruits have such protections in place.

    "Whether and when sane, sober, well-informed, adults should be banned by government authority from choosing to engage in an activity that risks their own life and limb is an ancient point of contention. There are a variety of hazardous activities that are permitted with no legal bar to receiving compensation. Included on this list are such occupations as logging, roofing, commercial fishing, and military service. Also included are violent sports such as football, boxing, and mixed martial arts (MMA). These examples illustrate a broad endorsement of the principle that consenting adults should be allowed to exchange (in a probabilistic sense) their physical health and safety for financial compensation, even in some instances where the ultimate product is simply providing a public entertainment.
    ...
    "In short, to the extent that the ban on compensated kidney donation is grounded in a concern that the lure of money may cause donors to disregard the risks of the procedure and subsequent long-term effects, that concern applies with even more force to participation in violent sport.

    "This, of course, is just a taste of our analysis and evidence, so read the full paper* for more."

    *If We Allow Football Players and Boxers to Be Paid for Entertaining the Public, Why Don't We Allow Kidney Donors to Be Paid for Saving Lives?
    Law and Contemporary Problems, Vol. 81, No. 3, 2018
    and by Philip J. Cook Kimberly D. Krawiec

    December 25, 2017
    Paying Kidney Donors, Football Players, And Boxers: Exploitation, Race, Class

    "We believe that using words like “coercion” and “exploitation” to characterize the introduction of a new option by which poor people (and others) could earn a substantial amount of money provides more heat than light on this situation. The legitimate ethical concern is that so many Americans are poor, with inequality increasing over time. But that observation does not support a ban on compensation, which in fact limits the options available to the poor and thereby makes a bad situation (their lack of marketable assets) worse. But for anyone not persuaded by this argument, we note that these social-justice concerns apply with at least equal force to compensating boxers; most American professional boxers were raised in lower-income neighborhoods, and are either black or Hispanic.
    ...
    "As more has become known about the dangers of the repeated head trauma, similar arguments regarding football have become more prominent. About 70% of NFL players are black, and Pacific Islanders are also overrepresented as compared to the American population. Accordingly, much attention has been paid to the concussion crisis as a race and class problem. As one observer recently noted, “What’s a little permanent brain damage when you’re facing a life of debilitating poverty?” In reality, NFL players are better educated themselves, and come from better educated homes, than is average for Americans, in part because the NFL typically recruits college students. Still, some NFL players, like some would-be kidney donors, come from poverty."


    December 26, 2017
    If You Oppose Paying Kidney Donors, You Should Oppose Paying Football Players And Boxers Too: Wrap-Up

    "In this series of posts, I’ve discussed a new draft that Phil Cook and I are circulating, If We Allow Football Players and Boxers to Be Paid for Entertaining the Public, Why Don't We Allow Kidney Donors to Be Paid for Saving Lives?. Our claim, which I laid out in my first post, is that there is a stronger case for compensating kidney donors than for compensating participants in violent sports. If this proposition is accepted, one implication is that there are only three logically consistent positions: allow compensation for both kidney donation and for violent sports; allow compensation for kidney donation but not for violent sports; or allow compensation for neither. Our current law and practice is perverse in endorsing a fourth regime, allowing compensation for violent sports but not kidney donation.
    A common argument in support of the ban on kidney donation is that if people were offered the temptation of substantial compensation, some would volunteer to donate against their own “true” best interests. This argument is often coupled with a social justice concern, namely that if kidney donors were paid, a large percentage of volunteers would be poor and financially stressed, and for them the offer of a substantial financial inducement would be coercive. In sum, a system of compensated donation would provide an undue temptation, and end up exploiting the poor.
    To these arguments we offer both a direct response, and a response by analogy with violent sport. My posts have touched on a few key points. First, the medical risks to a professional career in football, boxing, and other violent sports are much greater both in the near and long term than the risks of donating a kidney. On the other hand, the consent and screening process in professional sports is not as developed as in kidney donation. The social justice concerns stem from the fact that most players are black and some come from impoverished backgrounds."

    The post goes on to point out that the (life savings) benefits to kidney patients from kidney donation are huge, and it's hard to argue that they are less deserving or get less benefit than sports spectators. But you get the idea...

    Why Don’t Americans Eat Horse?

    From Eater.com, a long interesting summary of
    Why Don’t Americans Eat Horse?
    The red meat is common in many cultures, but rarely makes it on menus in the U.S. by Tim Forster

    "Killing horses isn’t technically banned in the U.S.; variations on an outright horse slaughter ban have surfaced but floundered in Congress several times since 2006. But appropriations committees did successfully ban funding to the USDA to inspect horse meat in 2007 — and if there’s no money for inspections, there’s no guarantee of safety, therefore it can’t be sold. In the words of a USDA spokesperson, “If there is no mark of inspection, then horse meat is not allowed to move in our national commerce.” This spelled the end for America’s three horse-slaughter facilities, closed a decade ago. (Their products had primarily been sent overseas.)"

    He makes the cultural argument (cowboys tamed the West), but I'm not convinced...

    Law Review submissions

    Law reviews, often among the most prestigious publications for law professors, are unusual in a number of respects.*  They are edited by students. And they allow multiple submissions: a paper may be simultaneously submitted to many journals, which respond with exploding offers of acceptances.

    Northwestern U. Law Review is exploring a different model: different from the usual law review submissions, but still very different from most academic disciplines.  Here's the announcement via the Faculty Lounge:

    Northwestern University Law Review Exclusive Submission Window

    This just in:
    The Northwestern University Law Review is pleased to announce our exclusive submission track for Spring 2018 submissions. We will accept exclusive submissions from January 1, 2018-January 14, 2018 at 11:59 PM Central Time. For all articles submitted in accordance with the instructions outlined below, the Law Review guarantees Articles Board consideration and a publication decision by February 5, 2018.
    More details are here, and after the jump.
    Articles receiving a publication offer via the exclusive submission track will be published in Volume 113 in the fall of 2018. Participating authors must agree to withhold the article submitted through our exclusive submission track from submission to any other publication until receiving a decision back from us. Authors not receiving publication offers are free to submit elsewhere after notification of our publication decision, which will occur no later than February 5, 2018. 
    Please note that by submitting an article via the exclusive submission track, the author agrees to accept a binding publication offer, should one be extended

    The courts take an interest in organ allocation rules

    The rules for how deceased donor organs are allocated to patients needing transplants are set by a long-established, slow and thorough bureaucratic process overseen by UNOS, which typically involves the deliberation of multiple committees and the solicitation of comments from many parties and the public.

    Recently the courts have taken an interest however. Here's a story from Modern Healthcare, about a court case brought on behalf of a particular patient in urgent need of a transplant.

    As stakeholders debate organ allocation rules, courts may push change

    "UNOS, the private, not-for-profit in charge of the organ transplant system, divides the country into 11 regions, essentially demarcating borders within which organs move from donor to recipient.

    "The system was abruptly changed as a result of the first legal challenge to these borders in years, which came Nov. 19, in Holman's name.

    "Attorneys filed an emergency complaint against HHS on her behalf. They sought an injunction on UNOS' regional policy that is much-debated but seldom changed.

    "The Holman lawsuit set in motion a rapid succession of government counter-appeals and new court orders. It culminated in a Thanksgiving change to a rule on lung allocation, expanding the procurement area to a 250-mile radius around a patient's donor service area.
    ...
    "As stakeholders debate the what-ifs, the waitlists in organ-scarce regions aren't getting shorter and patients like Holman and de la Rosa may spur the courts to draw their own conclusions, and possibly their own boundaries."

    HT: Frank McCormick

    And here's a story on the still-complex current state of affairs for the allocation of deceased-donor livers, from the NY Times:

    Organ donation in the UK: the particular case of children

    Children in need of transplants, particularly very young children, need appropriately sized organs, which can come from deceased donors of similar age. But there are obstacles, including family consent:

    Despite removal of many obstacles, UK child organ donation rates remain low

    "Despite the removal of many logistical/professional obstacles, and clear guidance from national bodies, UK child organ donation rates remain lower than in other comparable countries, say experts in a leading article published online in the Archives of Disease in Childhood.

    "Many families of dying children are simply not even given the chance to consider the option, and potentially save another child's life, they argue.
    ...
    "Family refusal remains a major obstacle to organ donation from children, emphasise the authors, but that is where trained staff are key, as they can ensure that "families are given the chance to consider donation, and that it is broached at the most appropriate time by the most appropriate person, and in the most appropriate way," say the authors.

    "Immediate focus should be given to consent rates and supporting family decision-making, they urge."
