One more reason why I love Sonos

No suburban paradise is complete without whole-house music. In setting up the latest here in Lincoln, Massachusetts I plugged in a Sonos ZP100 that the company’s records show I purchased in 2006 (yay for the RDBMS!). It failed to boot. I called the company on a Sunday, was connected to a competent native speaker of English, and offered the chance to pay about $150 (including shipping, tax, etc.) to swap the dead eight-year-old box for a working new one (retail price: $500). Of course they are sending me the new one right away and I will return the old one in the box that they provide.

Now my only complaint about Sonos is that they don’t make dishwashers

Golden opportunity for online universities: campus rape stories

The media are carrying a lot of stories about rape on campus lately. The latest is a retraction by Rolling Stone of a story about University of Virginia. The stories fall into various broad categories:

  • a high percentage of women who live on campus are being raped
  • universities falsify statistics and/or cover up rape reports
  • kangaroo courts set up by university administrators, at the behest of their federal overlords, are overly skeptical regarding rape allegations brought by women, resulting in men being wrongly acquitted
  • kangaroo courts set up by universities are insufficiently skeptical, resulting in men being wrongly convicted

If we combine the above concerns with the multi-decade trends of tuition costs outpacing inflation and parents wanting to supervise their child’s every moment (“helicopter parents”), it seems as though there is no better time to be marketing online education.

Western Governors University, for example, charges about $6000 per year, barely enough to pay for library coffee bar lattes at the universities that are featured in the news. Why wouldn’t they buy ad space next to stories about on-campus rape? The headline could be “Wouldn’t you rather keep your 20-year-old darlings safe at home? (and save $250k)”

Income inequality leads to lower marriage rates?

Today’s New York Times carries a story that shows a correlation between income equality and marriage rates. From this correlation, the author, an academic sociologist, infers causation.

For me the article raises a few questions. First, are the data presented correct? This almanac shows a steady marriage rate, per 1000 population, from 1900 to 1970, a period over which the article shows a huge increase in the rate at which American men in particular careers were actually married. The author uses “U.S. born men ages 20 to 49” for the chart. Just using this age range has the potential for distortion if the age of first marriage changes (example: if all men wait until age 50 to get married, the charted rate of marriage would go to 0). This almanac page shows that the age for men of first marriage did indeed reach a low point in the 1960s.

The second question would be why having an income lower than a successful physician or a Wall Street banker would lead to remaining single. A “poverty line” standard of living today is similar to a “middle class” standard of living in the 1950s. So two people who are officially “poor” can afford the same square footage of house and other items that were formerly considered requisites for being married. And if we still believe that “two can live as cheaply as one” (possibly even “three can live as cheaply as one” using UCLA Professor of Economics Bill Comanor’s analysis), wouldn’t people of modest means be more inclined to marry (or at least cohabit) than people of higher incomes?

A third question would be “What about international data?” https://www.census.gov/compendia/statab/2012/tables/12s1336.pdf shows that countries that are cited as examples of equality among citizens, such as Denmark and Sweden, have lower rates of marriage than the U.S. and higher percentages of children born to unmarried women.

There have been a lot of legal changes in the U.S. since the 1960s peak of marriage in the article’s chart. We have introduced no-fault divorce. We have introduced child support guidelines that make out-of-wedlock children equally profitable compared to children of a marriage. If you believe that one reason Americans get married is to realize an economic benefit by being able to spend the income of a partner, the law has substantially changed the incentives faced by Americans. It is no longer necessary to get married or stay married in order to spend someone else’s income (a one-night encounter in a bar in will suffice in every state, though the revenue is likely to be highest in California, Massachusetts, or Wisconsin). Could it be these legal and social changes that are driving any fall in rates at which Americans are getting or staying married?

Should we have unarmed police?

Apropos of the recent protests regarding Americans killed by police… Now that the crime rate has fallen so much in the U.S., why continue to arm the typical police officer? It is true that we are a nation of gun nuts, but it is still a minority of Americans engaged in criminal activity who carry guns, right? Why should every police officer bring a gun onto the scene? That would seem to invite a huge escalation of the violence, either with the officer afraid that the suspect is going to grab the gun or that the suspect might choose to shoot him or her before the gun can be pulled out, etc. The British seem to manage with the first line of law enforcement being unarmed with deadly force. Is it crazy to think that it could work here? (The Economist did a comparison of shootings by police in Britain versus the U.S. in an August 15, 2014 story.)

Best way to publish a narrated slide show?

Folks:

I have about 200 images from Burning Man that I’d like to present with audio narration. I want the slides to be shown at maximum quality (i.e., I’m not sure if an MPEG video from YouTube is the best idea). I want to record the audio and the timing/sequence myself. Right now the slides are already a Google Plus album (friends who are programmers at Google: Why isn’t this a standard feature? “Add narration to an album”? Microsoft PowerPoint lets you do it, so it can’t be impossible to code.).

What’s the most practical way to do this? If worst comes to worst I guess I wouldn’t mind publishing it as a 1080p video on youtube.com but even then I have to author it somehow. I do have Adobe Premiere but I feel that there should be an easier way to author. I think that if I make every photo a PowerPoint slide I can have PPT export a WMV file.

Thanks in advance for any help.

Oberlin College Ghetto Dorms

I toured Oberlin College today with a friend and his son, a high school senior looking for a place to study science. For someone who has spent most of his time on the campuses of research universities, I was struck by how the students talked about their professors as accessible, dedicated to their learning, and “the best thing about Oberlin.” At MIT and Harvard, for example, professors are generally rather remote figures from the perspective of an undergraduate. With some help from Mindy the Crippler we met with a wide range of students and all spoke positively about their experience at Oberlin.

I was also struck when the student guide told us about a dormitory with an African heritage theme and specializing in serving “soul food” (link). She also mentioned a “Third World House” where “people of color” and “of low socioeconomic status” could live (link). It seemed odd that a college administration could set up places like this. Suppose that the school put out a Web page saying that “70 percent of our students are white and from wealthy families. Despite their stacks of cashmere sweaters, they wouldn’t feel comfortable living with anyone who was poor or black. So we’d appreciate it if students with darker skin or without a closet full of designer outfits would please move into Third World House or Soul Food Dorm.” If it wouldn’t be okay to do that, why is it okay to have the houses at all? Does having the best and most inclusive intentions make it okay to do something that might otherwise appear racist and classist?

[Separately, we learned about a house for women and transgender students (link) and talked to a young woman who’d applied to live there. She explained that it was open to anyone who had female chromosomes and identified as “female” and also anyone who was transgender. The only students to whom the living group was closed were males who identified as “male.”]

Family Law Reform Conference Report

Here are some notes about the things that struck me when attending the Divorce Corp. Family Law Reform conference, November 15-16 in Washington, D.C.

Joe Sorge opened the conference by framing some of the issues (slides). In his view, setting up a litigated winner/loser system is harmful to children because (1) it takes a long time, (2) tends to inflame tensions between parents, and (3) drains parental financial resources. Additional harm is done by having a single human being, the trial court judge, make all of the decisions regarding a child’s future (as a practical matter, because these are decisions of “fact,” a divorce court judge’s decisions are not reviewable by an appeals court). Why is the end of a short-term American marriage a mad litigated grab for kids, cash, and long-term financial support for apparently healthy working-age adults? Sorge, whose own former partner collected assets worth about $14 million from him in her first lawsuit against him, had to keep defending additional actions (seeking more money) for a 12-year period. He noted that Federal Law, via Title IV-D of the Social Security Act, provides financial incentives for states to establish a “dominant” parent and entering child support awards to be paid by the secondary parent to that primary parent. Necessarily there were explicit disincentives therefore for states to award shared parenting. Sorge thought that the divorce industry was an anachronism that persisted due to its use of some of its $50 billion in annual revenue for lobbying. He pointed out that in the 1970s only 30 percent of mothers worked while today approximately 70 percent of mothers do. “Women age 25-34 make 88 percent of what men earn,” Sorge pointed out. There is thus a system built on the assumption that women cannot or will not work embedded in a society where women, at least those who are not alimony and child support recipients, do generally work.

Sorge pointed to Sweden as a model. Divorce is generally an administrative procedure, akin to working with the IRS on taxes in the U.S. Only about 1-2 percent of divorcing couples end up embroiled in the legal system there. You can’t get rich having a child with a high-income co-parent. Child support is fixed, according to Sorge, at roughly 1/2 the cost of feeding and clothing a child. Each parent is responsible for half of this amount (currently about $4000 per year total, which means $2000 per parent per year). Although litigation is much cheaper in Sweden than in the U.S., it is discouraged by the country’s practice of making each parent pay his or her own fees, unlike in many U.S. states (such as Sorge’s California) where a $200,000/year plaintiff can get a $300,000/year defendant ordered, as a matter of routine, to pay the fees on both sides of the lawsuit (thus removing any incentive for the plaintiff to settle).

The first formal presentation was by Malin Bergstrom, a Swedish epidemiologist who used data from a national survey of 172,000 children aged 12-15 (slides). Due to the lack of financial incentive to seek sole parenting in Sweden, approximately 40 percent of Swedish children of separated parents live in a 50/50 arrangement. This plus the fact that she used a comprehensive national survey means that Professor Bergstrom worked from better data than any previous researcher on the every-other-weekend versus shared parenting question. Her results? An intact family is best for kids, but a 50/50 arrangement is pretty close in terms of the child’s mental and physical health. Children who lived primarily with their mother did substantially worse and children who lived primarily with their father were even more disadvantaged. Bergstrom noted that when a mother has pulled back to every-other-weekend (or less) in Sweden it is usually due to mental health or substance abuse problems.

The U.S. is unusual internationally due to the following factors: (1) there is no official custody presumption (i.e., children are up for grabs), (2) obtaining custody of children can be more profitable than going to college and working, and (3) litigation is the default process for a divorce or a custody and child support determination. No society in the history of humanity has ever devoted as high a proportion of its resources to custody litigation and wealth transfers via child support. I talked with Bergstrom a couple of times privately during the conference. She said that she hadn’t known anything about the U.S. system before coming to speak and was amazed that a society would set things up the way that we had. In response to the clinical psychologists who said that they wanted to be involved (paid) in every custody lawsuit to determine which parent had a narcissistic or borderline personality disorder, she said “Don’t you need to have a system for normal loving parents as well?”

One area that has been mystifying is why American parents fight so hard over custody and parenting time schedules that affect child support revenue. The fight plainly makes financial sense when $200,000 per year in tax-free cash is at stake (e.g., when suing a radiologist or dermatologist), but why when the numbers are closer to the USDA-estimated costs of child-rearing? And if kids are really as expensive as state child support guidelines suggest, why don’t married parents put most or all of their children up for adoption? For our forthcoming book on divorce, custody, and child support laws in the 51 jurisdictions nationwide we interviewed policy makers in a variety of states. An Illinois family law drafter (and also a working divorce litigator, as seems to be the typical arrangement nationwide (i.e., the litigators write the laws)) was presented with a hypothetical scenario of two physicians, each of whom earned $200,000 per year after taxes, with two children together. Assuming a 60/40 parenting time split, the loser would pay the winner $56,000 per year in tax-free cash. Assuming young children, therefore, the wealth difference for these two equal earners would be approximately $2 million by the time the kids aged out. The policy maker responded that the parents would not be motivated by this $2 million to seek to become the 60-percent parent as opposed to the 40-percent parent. “Child support does not compensate the parents for having children,” she said, taking the position that $56,000 was not nearly enough to pay the expenses of two children.

William Comanor, a professor of economics at UCLA, shed some light on the issue (slides). Economists have identified two main flaws in the typical state’s child support guideline numbers. The first is that the non-custodial parent, e.g., the one who takes care of a child 40 percent of the time in the above example, is considered to have zero expenses for housing, food, clothing, transportation, etc. The system as designed, therefore, gives the primary parent’s household a much higher share of the combined parental income than the secondary parent’s household even when the children spend a substantial percentage of their time with the secondary parent. Comanor did not address this issue, which has been previously covered by economists (see this 2013 report to the Massachusetts commission).

Comanor’s talk, and a forthcoming journal article, related to how people figure the actual cost of children in intact families, which is the starting point for many child support calculations (“Put yourself in the child’s diaper,” one California attorney said, saying that the relevant question for the judge is “How much would have been spent on the child if these two people, instead of just meeting for one night in a bar, had gotten married and stayed together until the child turned 18?”). Big components are food, housing, and transportation. How much does a married couple with one child spend on transportation for the child? The conventional approach has been to take what they spend on transportation and divide by three. Comanor used the same U.S. Census Bureau data regarding consumer expenditures that the USDA uses and found that the actual number is pretty close to $0: married couples with and without children (except low-income families with three or more children) spend about the same on transportation. Similarly for housing. Some approaches take the cost of a house or apartment and divide by the number of people occupying it. Other conventional approaches have been to estimate the housing cost of a child by looking at the marginal cost of a two-bedroom apartment compared to a one-bedroom apartment. Professor Comanor looked at what American couples, with and without children, actually do spend. It turns out that on average a married couple with no children will spend the same as a married couple with one child. Maybe a guest bedroom or den turns into a nursery but the actual dollars spent doesn’t change until the second child comes along. Similarly, spending on food is about the same before and after the first child arrives. Comanor finds that the basic cost of a child in an American household with less than $56,000 per year in pre-tax income is about $4300 per year, i.e., not very different from the Sweden child support number and about the same as what some Western states use as the starting point for child support (adding in an extra amount for luxuries if the parents’ income is larger than $15,000 per year or so). Comanor’s number is somewhat lower than foster care reimbursements in most states ($6000 to $8000 per year per child). That’s about 10 percent of the top of the Massachusetts child support guidelines (suing a $250,000/year earner yields $40,000 per year in tax-free child support), which means that a Massachusetts plaintiff could expect a 90-percent profit on child support revenue, assuming that the child’s clothes are purchased at Target.

[A smaller issue with child support guidelines is that spending by single-parent households may be overstated. Since child support is not “income” a single parent with a $50,000-per-year job who collects $50,000 per year in tax-free child support may fall into the “$50,000 per year” income category, though he or she would have a spending power closer to that of a person with $135,000 per year in taxable income. There would still be a lack of comparability if the example single parent were considered to have a “pre-tax income” of $100,000 per year because a married couple with $100,000 in income would pay taxes on all of it. Comanor wasn’t sure which conventional approaches, if any, were adjusted for these factors. His own analysis shows higher spending on children in “single households” than “married households” with the same “income”.]

Using OECD data on the amount of hands-on time put into child care by working parents (about one hour per day, averaging weekends and weekdays) and Comanor’s analysis of the Census data, obtaining custody of a child and collecting child support should be worth about $150 per hour at the top of the Massachusetts guidelines, for example (assumes two-thirds/one-third parenting time split and a $250,000-per-year income for the loser parent). The Bureau of Labor Statistics says that a “private nonfarm” worker in American earns an average wage of less than $25 per hour. Given that child support is tax-free and wages are taxable, a thoughtful custody and child support plaintiff should be able to earn at least 8X per hour compared to a W-2 employee.

Attorneys whom we interviewed both before and at the conference told us that allegations of child abuse are common whenever profitable custody of children is being sought. Dr. Joyanna Silberg (web site), in a panel discussion, noted that children are not being protected from actual abuse: “Family court looks at children as property for one side or the other.” What does this experienced therapist say about the custody evaluation or guardian ad litem process engaged in by psychologists nationwide? “It’s a game of chance whether a custody evaluator gets it right,” she said. Silberg noted that the divorce industry misleads with precise-sounding terms that are meaningless to psychology professionals.

New York’s new train station

The Tax Foundation says that New York collects a higher percentage of residents’ income than any other state. How does the money get spent? The New York Times has an article on a new $4 billion train station for lower Manhattan. If it does not slip further it will have taken 11 years to complete (when it opens in 2015).

What can $4 billion buy in terms of passenger train infrastructure? Wikipedia says that was roughly the cost of the Zhengxi PDL high-speed rail line in China (built starting in 2005 when the exchange rate was different). For a return on their $billions, the Chinese waited five years rather than 11. Instead of 1 train station they got 10 train stations plus a 284-mile-long railroad connecting them. Trains travel along the line at roughly 220 mph. As part of this package, the Chinese also got the longest bridge in the world at the time and an assortment of tunnels, some more than five miles long.

Thanksgiving Gratitude

Five years ago I posted a list of things for which I was grateful.

I’m still grateful for all of the stuff that I was grateful for in 2009. What since then, though?

Here’s my list (mostly small items because the big ones are on the earlier list)…

  • the two wonderful women in our house
  • our healthy baby, born 2013
  • that my former aviation students have enjoyed five more years of safe flying
  • that my friends who fly have similarly kept themselves and their passengers safe
  • a former co-worker who relocated to Boston and has become the best possible friend
  • old friends who proved their durability during some trying times
  • Mindy the Crippler, PC
  • finding a new way to teach database programming that is fun for both students and teachers (see the January 2015 course announcement)
  • the continued expansion of the Internet*
  • practical tablet computers, notably the Apple iPad, which delight both children and adults
  • smart phones big enough to serve as tablet computers
  • Dropbox and Google Drive, which mean that I can almost always find everything that I need
  • the new (2010) Art of the Americas wing at the Boston Museum of Fine Arts, which keeps a favorite five-year-old of mine entertained
  • Uber
  • Sonos
  • that we got to visit Antarctica (my report)
  • Sony A6000 mirrorless camera system (and its predecessor, the NEX-6)

*Internet success story: Contractor and plumber installed a new washer/dryer in the house. I am pretty sure that they didn’t read the instructions before test running it. When I opened up the washer after it had walked itself 1.5 feet across the floor due to being unbalanced I found the (ruined) manual inside, along with the hoses and some other little bits. I then went to the Samsung web site and found the manual, which said “remove the transit bolts before running or the machine will become unbalanced.”

What about readers? What are you all grateful for, beyond the basic friends, family, health, food, and shelter stuff?
