A deportation delayed, to allow for a kidney exchange.

Here's a complicated story:

KIDNEY TRANSPLANT: Brother gets reprieve before deportation to Cambodia

"A life-and-death fight by two Stockton brothers to delay the deportation of one of them for humanitarian reasons appears headed toward a positive outcome for the men, who came to the United States from Cambodia as refugees in 1985.

"A recent ruling by U.S. Immigration and Customs Enforcement will allow Touch Hak, 38, to remain in this country for three more years before his deportation for a past drug offense.

"Those three years will allow Hak to participate in a paired kidney-donation program intended to help his brother, 50-year-old Puthy Hak, receive the transplant he needs to remain alive.

“I did my (prison time) for nine years,” Touch Hak said Monday. “I tried to really rehabilitate myself. It’s a lot of weight lifted from our shoulders. All I want to do is give my brother another chance. This will open another door for him.”

Alcott and Kessler on behavior and welfare changes from 'nudges"

An NBER working paper:

The Welfare Effects of Nudges: A Case Study of Energy Use Social Comparisons
Hunt Allcott, Judd B. Kessler
NBER Working Paper No. 21671
Issued in October 2015

"Nudge"-style interventions are typically evaluated on the basis of their effects on behavior, not social welfare. We use a field experiment to measure the welfare effects of one especially policy-relevant intervention, home energy conservation reports. We measure consumer welfare by sending introductory reports and using an incentive-compatible multiple price list to determine willingness-to-pay to continue the program. We combine this with estimates of implementation costs and externality reductions to carry out a comprehensive welfare evaluation. We find that this nudge increases social welfare, although traditional program evaluation approaches overstate welfare gains by a factor of five. To exploit significant individual-level heterogeneity in welfare gains, we develop a simple machine learning algorithm to optimally target the nudge; this would more than double the welfare gains. Our results highlight that nudges, even those that are highly effective at changing behavior, need to be evaluated based on their welfare implications.

Making the market for medical marijuana a little less medical

The NY Times has a story on how easy it is to get a prescription for marijuana in states like California, where medical marijuana is legal but recreational marijuana is  not supposed to be:
Silicon Valley Tries to Alter Your Perception of Cannabis

"One morning in September, I logged on to the website of HelloMD, a medical start-up that promises to connect patients with doctors instantly over the Internet. I filled out my personal details, explained my ailment — I often get heartburn — and entered in my credit card number to cover the $50 consultation fee.

"Within 10 minutes, a pediatrician based near Washington who is licensed to practice medicine in my home state of California popped up on my screen. ...

"The doctor asked about my medical history, current symptoms and familiarity with certain medicines. The interview lasted about three minutes, after which she announced what everyone who visits HelloMD expects to hear: According to her diagnosis, my heartburn made me a candidate for medical marijuana, which has been legal in California since 1996."
Marijuana may eventually be legalized for recreational use in California (as it already is in Colorado, Oregon and the state of Washington). But the market isn't waiting for that:

Matchmaking among the Haredi

Ynet has a story: 
Ultra-orthodox matchmaking: everything it's best not to know

"Among the traditional Haredi public – not the modern stream, which has changed in recent years – pairing one's children is the exclusive responsibility of parents. No yeshiva boy is supposed to choose a girl himself. When parents think the time is right, the phase known as "starting to listen" begins – that is, taking suggestions and statements from matchmakers. For the Hasidim it happens around the age of 18, sometimes even younger. For Lithuanians and Sephardim, it's around the age of 20.

"During this stage parents approach matchmakers, tell them about their son or daughter and specify what they are seeking for their child. Finally, much like in the job market, they give the names of their relatives, neighbors and teachers who can provide those interested with "recommendations," or simply additional details.

"When the two sides feel that the stats are good, a meeting between the couple will be arranged. In most Haredi communities the couple will meet a maximum of three times before they become engaged. In the more devout Hasidic communities, the strict rules permit only one meeting, lasting about 20 minutes. The rationale: they will probably develop feelings, and feelings are bad for business.
"Haya, a neighbor of mine, got hitched to a match 38 years ago and is still married. To the same man. Eight out of her 15 children got married in the same way. "We aren't looking for love," she tells me. "We don't marry because I love you or you love me. We have a common goal – to build a home in Israel – and we work together in order to achieve that aim."
