Towards greater gun safety in San Jose

 The mayor of San Jose, CA, has some thoughts on making guns and gun ownership less dangerous, in a  NY Times opinion column:

400 Million Guns Aren’t Going to Just Go Away. In San Jose, We’re Trying Something New. By Sam Liccardo (Mr. Liccardo, a Democrat, has been the mayor of San Jose, Calif., since 2015. He is a former federal and local prosecutor.)

"Amid the rising tide of firearms, reducing gun deaths and injuries requires new solutions. In San Jose, Calif., where I am mayor, we’ve embarked on two approaches untried in any other city or state: We’re imposing an annual fee on gun-owning residents and investing the revenues in violence prevention efforts. And on Jan. 1, the city will begin requiring gun owners to carry liability insurance to compensate victims harmed by the negligent or reckless use of a firearm.

...

"Most gun-owning residents can comply with the insurance mandate with little or no additional cost under standard homeowners’ and renters’ policies. As more jurisdictions adopt an insurance requirement — legislators in New Jersey and California have recently proposed them — we expect that the insurance industry will become increasingly invested in reducing gun-related harm. Premiums will reflect the risks of gun ownership and will adjust accordingly, in the same way that auto insurers offer “good driver” discounts or how they incentivized the installation of anti-lock brakes and airbags in the past.

"Of course, in the realm of gun regulation, no good deed goes unlitigated. Three groups sued San Jose after the ordinance imposing the fee and insurance requirement passed. A Federal District Court declined their pleas for an injunction to stop the ordinance from taking effect, finding no unconstitutional burden on Second Amendment rights where “there are no means by which a San Jose gun owner may be deprived of his or her firearm.”

Roundabouts

 A straight line isn't always the safest path between two points.

The Washington Post has the story:

Roundabouts are (slowly!) eating the suburbs by Andrew Van Dam

"Compared with the hundreds of thousands of normal intersections peppering the American landscape, ruled by stop signs and traffic lights, roundabouts are rare beasts. But unlike the drivers they frequently confuse and bedevil, roundabouts are coming on fast.

...

"The modern roundabout relies on a geometric design that forces traffic to slow, plus a simple innovation born in 1960s Britain: the rule that people already in the circle get the right of way. In traditional rotaries and traffic circles, which still lurk in many East Coast cities, traffic moves faster and vehicles already in the circle often must yield to newcomers.

...

"Why add a roundabout, you might ask. Because roundabouts offer impressive safety gains. In general, a roundabout will drive down fatal crashes by 90 percent and cut all car-crash injuries by at least 75 percent, even while accommodating a higher volume of cars.

"At a rural two-way stop, the gains can be even more dramatic. A roundabout can slash all traffic injuries, both fatal and nonfatal, by almost 90 percent. After all, it’s almost impossible to blow through a roundabout at 60 miles an hour and T-bone a minivan — an all-too-common occurrence in typical rural intersections.

“That’s the beauty of the roundabout,” Rodegerdts told us. “It’s the geometry. It’s the curves that are doing the work. And not relying on a traffic-control device as the sole thing keeping you from colliding at high speed.”

Nevertheless...here's a related NYT story:

The Exceptionally American Problem of Rising Roadway Deaths

Why other rich nations have surpassed the U.S. in protecting pedestrians, cyclists and motorists. By Emily Badger and Alicia Parlapiano

"In 2021, nearly 43,000 people died on American roads, the government estimates. And the recent rise in fatalities has been particularly pronounced among those the government classifies as most vulnerable — cyclists, motorcyclists, pedestrians.

...

"In the 1990s, per capita roadway fatalities across developed countries were significantly higher than today. And they were higher in South Korea, New Zealand and Belgium than in the U.S. Then a revolution in car safety brought more seatbelt usage, standard-issue airbags and safer car frames, said Yonah Freemark, a researcher at the Urban Institute.

"Fatalities fell as a result, in the U.S. and internationally. But as cars grew safer for the people inside them, the U.S. didn’t progress as other countries did to prioritizing the safety of people outside them.

“Other countries started to take seriously pedestrian and cyclist injuries in the 2000s — and started making that a priority in both vehicle design and street design — in a way that has never been committed to in the United States,” Mr. Freemark said.

"Other developed countries lowered speed limits and built more protected bike lanes. They moved faster in making standard in-vehicle technology like automatic braking systems that detect pedestrians, and vehicle hoods that are less deadly to them. They designed roundabouts that reduce the danger at intersections, where fatalities disproportionately occur.

"In the U.S. in the past two decades, by contrast, vehicles have grown significantly bigger and thus deadlier to the people they hit. Many states curb the ability of local governments to set lower speed limits. The five-star federal safety rating that consumers can look for when buying a car today doesn’t take into consideration what that car might do to pedestrians."

Motorcycles as donorcycles

 Here's an article from JAMA Internal Medicine, noting that motorcycle rallies produce an increase in organ transplants.

Organ Donation and Transplants During Major US Motorcycle Rallies  by David C. Cron, MD, MS; Christopher M. Worsham, MD; Joel T. Adler, MD, MPH; Charles F. Bray, BS; Anupam B. Jena, MD, PhD,  JAMA Intern Med. Published online November 28, 2022. doi:10.1001/jamainternmed.2022.5431

"Key Points

Question  Is the incidence of organ donation and transplants higher during major US motorcycle rallies?

Findings  In this cross-sectional study of 10 798 organ donors and 35 329 recipients of these organs from a national transplant registry from 2005 to 2021, there were 21% more organ donors and 26% more transplant recipients per day during motorcycle rallies in regions near those rallies compared with the 4 weeks before and after the rallies.

Meaning  While safety measures to minimize morbidity and mortality during motorcycle rallies should be prioritized, this study showed the downstream association of these events with organ donation and transplants."

***********

Helmet laws by State (only the States in orange require all motorcycle riders to wear a helmet):

I wonder what would happen if some State passed a helmet law saying that adults are free to ride without a helmet, but doing so automatically registers the rider as a willing deceased donor. (Such a law might decrease deceased donation by convincing more riders to wear helmets.)

Disrupting black markets: call for papers

 Laws banning markets often create black markets. And the same technologies that facilitate legal markets may do so for illegal markets that we would like to extinguish, e.g. involving human trafficking, trade in endangered species or drugs, ransomware, etc.

How can we control such markets?

Mike Luca on social media bans

 Mike Luca writes, in Wired, about social media bans as part of their design.

Social Media Bans Are Really, Actually, Shockingly Common--Booting Trump didn’t set a precedent. From Yelp to Uber to Airbnb, platforms regularly ban users and content, but too often behind the scenes.

"DONALD TRUMP’S ACCOUNTS have been banned on Twitter, Facebook, and a host of other platforms. Every last one of @realdonaldtrump’s 47,000 tweets vanished from the site in an instant, from the birther lies and election conspiracy theories to the 2016 taco bowl tweet. In an explanatory blog post, the company cited the attack on the Capitol and “the risk of further incitement of violence” that might occur by permitting further Trump tweets. His multiplatform removal has drawn cheers from many, as well as the ire of more than a few Trump supporters. The bans have also raised concerns that the companies had gone too far in exercising their power to shape what users see.

...

"To combat review fraud, Yelp and other platforms flag reviews they deem spammy or objectionable and remove them from the main listings of the page. Yelp puts these into a section labeled “not currently recommended,” where they are not factored into the ratings you see on a business’s page. The goal of approaches like this is to make sure people can trust the content they do see.

...

"Ultimately, removing content can be valuable for users. People need to feel safe in order to participate in markets. And, it can be hard to trust review websites riddled with fake reviews, housing rental websites rife with racial discrimination, and social media platforms that are megaphones of misinformation. Removing bad content can create healthier platforms in the long run. There is a moral case for banning the president. There is also a business case."

Residential real estate sales, social distancing, and traditional marketplace institutions

In some places, residential real estate is an essential service (open houses allowed) and in others not.  Virtual, internet showings are becoming more important.
But some of the particular marketplace institutions, of closing and title ceremonies (including notarized signatures) resist social distancing, and in many U.S. states must be conducted in person. Of course, the security of undisputed ownership is of huge importance in real estate, and online security is imperfect (I'm told...), so it isn't clear how to proceed here.

Here's a story from the Washington Post:

With hand sanitizer and elbow bumps, real estate agents are still selling during pandemic
By Kathy Orton

"Now, as nonessential businesses are shuttering to wait out the pandemic, some real estate professionals are carrying on as usual — albeit with masks, gloves and hand sanitizer. Agents were holding open houses until they were prohibited by local officials. Nearly 200 open houses were listed last weekend and more than 600 open houses the week before in the D.C. region on the area’s multiple listing service. Mayor Muriel E. Bower (D) banned open houses as of Saturday; Maryland Gov. Larry Hogan (R) and Virginia Gov. Ralph Northam (D) forbid them as of Monday.

"Home appraisers and inspectors are donning masks and gloves. Settlement companies are putting buyers and sellers in separate conference rooms and opening a new box of pens for each client who comes to a closing.
...
"Illinois, despite being hit hard by the coronavirus outbreak, has said that real estate is an essential service, and therefore is not required to close like retail outlets and restaurants.

"But California, New York and Pennsylvania have said it is not. Seattle’s multiple listing service no longer allows agents to post open houses.
...
"The number of 3-D home tours created on Zillow went up 326 percent on March 20.
...
"Although many aspects of buying a home can be done online, certain parts of the process — inspection, appraisal, closing — typically are done in person.
...
"According to Todd Ewing, chief executive at Federal Title, Fannie Mae and Freddie Mac are reluctant to buy loans without legislation that allows for remote online notarization.

"Some states, including Virginia, permit remote online notarization, but others such as the District and Maryland, do not. Federal legislation was introduced on March 18 that would allow it in all states."

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

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

Here's the Singapore story from the Guardian:

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

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

"One incident involved obscene images appearing on screens and male strangers making lewd comments during the streaming of a geography lesson with teenage girls, media reports said."

Here's the NYC story from CNN:

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

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

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

Rare whiskey: destructive testing

The Guardian breaks the news:
Rare whisky market flooded with fakes, says dealer
Lab tests found 21 out of 55 bottles of allegedly vintage scotch were counterfeit

"Simpson said it was not yet clear what systematic checks would work since the only accurate way of testing a whisky at present was to open the bottle and subject the liquid to chemical testing or the carbon testing techniques used by the Scottish centre.

"However, opening the bottle destroyed its value, making it impossible to prove its provenance while ensuring it could be sold on if it was found to be genuine. It would need the police or food safety authorities to tackle the problem, he said, by tracking a fraudulent bottle to its source."

Safe exchange zones

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

See e.g. this recent story from New Jersey, where the police department set up a safe exchange zone following a robbery/murder:

Online shoppers urged to use safe exchange zones for transactions

"Passaic Mayor Hector Lora says that his town installed the zones inside and outside of the police station after a series of robberies and scams related to online sales.

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

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

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

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

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

Harm reduction (for opioids) in Canada

Here's a story from the Washington Post:
At the heart of Canada’s fentanyl crisis, extreme efforts that U.S. cities may follow

"the Overdose Prevention Society, took over a vacant building next door, giving users a clean indoor place to inject drugs. There are 29 similar sites in British Columbia, the epicenter of Canada’s drug crisis, and more across the country.

“To save lives, you need a table, chairs and some volunteers,” said Sarah Blyth, the manager here.
...
"As fentanyl rampages across North America, several U.S. cities have announced that they will open the first supervised drug-consumption sites like those in Canada. Their plans illustrate the gulf between the two nations: While Justin Trudeau’s government is doubling down on its “harm reduction” approach, any U.S. organization that tries to follow suit would be violating federal law and risking a confrontation with the Justice Department.

Uneven playing fields in school choice: the consequences of manipulability

 Here's a study of a school choice system using the manipulable (not strategy proof) immediate acceptance ("Boston") algorithm for school choice, in the Wake County Public School System in North Carolina, the 15th largest in the U.S. (The authors are all market design economists at North Carolina State University.)

Identifying the Harm of Manipulable School-Choice Mechanisms

Abstract: An important but under-explored issue in student assignment procedures is heterogeneity in the level of strategic sophistication among students. Our work provides the first direct measure of which students rank schools following their true preference order (sincere students) and which rank schools by manipulating their true preferences (sophisticated students). We present evidence that our proxy for sophistication captures systematic differences among students. Our results demonstrate that sophisticated students are 9.6 percentage points more likely to be assigned to one of their preferred schools. Further, we show that this large difference in assignment probability occurs because sophisticated students systematically avoid over-demanded schools.

Here's the operational definition of a sophisticated student:
" In their application procedure, students have a two-week window during which they must log into a website and submit their preferences. A student is free to change her ranking as many times as she wishes. Moreover, upon each visit, a student learns how many students have ranked each school first. Therefore, a sophisticated student benefits from logging into the website multiple times or logging in closer to the deadline. On the other hand, a student submitting her true preferences needs only to log into the website once.
"Following this logic, our classification of sincere and sophisticated students is drawn from the number of logins to the application website. Specifically, we classify students who log in once as sincere and those who log in more than once as sophisticated. We then show a series of results to demonstrate that our login proxy for sophistication is capturing important, systematic differences across students. For instance, some students who visit the application website multiple times change their rankings near the end of the selection period by removing popular (i.e., over-demanded) schools from the top of their rankings. More generally, we demonstrate that sophisticated students avoid over-demanded schools by not ranking them as their first choice. As a result, sophisticated students are more likely to receive an assignment but, conditional on receiving an assignment, are less likely to be assigned to a highly over-demanded school."

Uber and "safety by design"

I've written a lot about how marketplaces have to help markets become thick, deal with the congestion that can accompany thick markets, and make the market safe to participate in.  I just got a nice email from Uber illustrating how they are thinking about that third point, on the rider side of the market.
