Welfare paternalism

Paul Ryan's welfare plan, including stronger reliance on case managers to guide clients out of income support and into work, reminds me an awful lot of the Beaulier and Caplan piece on behavioural economics and welfare. It was published in Kyklos; the link above goes to the ungated version.

I'd paraphrased their paper a few years ago:
If we take behavioural economics seriously, we've good reason to believe that the anomalies it describes are found primarily among the poor and are exacerbated by the welfare system. Poor people are more likely to exhibit behaviours that reflect more than just high rates of time preference: they demonstrate little ability to foresee the consequences of actions. The poor (and less educated / lower IQ - the two go together) are more likely to be heavy drinkers, to be obese, to smoke, to buy lotto tickets, to take illegal drugs, and to commit even non-economically motivated crimes (theft would not be surprising, but violent crime isn't lucrative). Low IQ amplifies behavioural anomalies. And, the dole makes things worse. If you start out with big self-control problems, you're likely to overestimate your ability to motivate yourself to find work - "I'll go on the dole for now but will look hard for work tomorrow". Absent the income backstop, you'd have to look for work. Worse, if welfare payments are more comfortable than the first year of work, after which work is better as income rises, folks with high discount rates and self-control problems may decide never to leave even though it would be in their long run interest. Consequently, welfare payments may make welfare recipients worse off, contra neoclassical economics.
Ryan's plan has recipients working with case managers to develop short- through long- term goals, with wraparound tailored support in place of some current federal programmes:
The OG system will promote a more holistic form of aid to move individuals and families out of poverty. One promising method this proposal envisions is the use of case management. Here’s an example of the number of steps illustrating the OG in practice:
  • First, each state will approve a list of certified providers that are held accountable for providing quality service and achieving results (such as moving people to work, out of poverty, and off of assistance).
  • Next, a person will select a provider, and the provider will conduct a comprehensive assessment of that person’s needs, abilities, and circumstances. 
  • Then, the two of them will develop a customized plan to address the recipient’s needs. The plan could take the form of a contract—with sanctions for failing and bonuses for exceeding expectations. The plan would offer financial assistance to address immediate needs, like food, clothing, child care, and housing. But it would also work on setting goals, learning skills, and developing a broader support system.
  • At the most basic level, successful completion of a contract will involve an able-bodied individual obtaining a job and earning enough to live above the poverty line. Each state may choose to define success slightly differently insofar as those basic conditions are met.
I'm not a particular fan of paternalistic approaches. They're insulting. But at least this variant is targeted at those who have demonstrated that they need a bit more of this assistance. Further, help to get out of poverty already comes with strings. Between this kind of approach and one that simply provided a minimum income with no strings, well, it's a tough call. I don't like the paternalism, but I do expect it could be more effective in getting people into better situations, conditional on there being some sufficiently competent and empathetic army of social workers to do the job.

Nerd Pride

Tyler Cowen reminds us of a Hanson point: politics is about status.
I was disappointed but not surprised by this passage by Gary Silverman:
What I like about Obamacare is that it shows some respect for “those people” – as Hudson called them in Giant – who are good enough to work the fields and mow the lawns, and build the roads and sew the clothes, and diaper the babies and wash the dishes, but somehow aren’t good enough to see a doctor from time to time to make sure there is nothing wrong inside.
That is in fact what most of politics is about, namely debates over which groups should enjoy higher social status and which groups should receive lower social status. Of course critics of Obamacare have their own versions of desired status reallocation, typically involving higher status for the economically productive.

...

The deeper point is that virtually all of us argue this way, albeit with more subtlety. A lot of the more innocuous-sounding arguments we use all the time come perilously close to committing the same fallacies as do these quite transparent and I would say quite obnoxious mistaken excerpts. One of the best paths for becoming a good reader of economics and politics blog posts (and other material) is to learn when you are encountering these kinds of arguments in disguised form.
I agree.

And so we come to Noah Smith's article wishing for higher nerd status, or at least an end to nerd-bashing.
Seriously, America. The nerd-bashing has gone too far. Sure, there is a grain of truth in all of the criticisms of the tech industry -- but only a grain. Yes, startups are riskier than many founders realize; but founders are people with good skills who will never go hungry. Yes, San Francisco rents are out of control, but this is more about development policy and NIMBYism than Google and Apple. Yes, inequality is increasing, but it’s increasing across all industries and classes, and bashing Silicon Valley isn't going to stop the march of automation. Yes, big American companies and corporate governance need to improve, but bashing “disruptive” startups isn't going to help the situation. Yes, some tech companies ignore the public interest when pushing for deregulation, but show me an industry that doesn’t do that. Yes, there are sociopaths and wackos among the ranks of tech entrepreneurs, but they’re certainly a tiny minority. (The only tech industry problem that really seems to live up to the hype is the sexism.)
...
We’re looking for rich, successful people to bash. And Silicon Valley happens to be where the rich, successful people are right now. So we’ve turned on the nerds.
... 
Still, I’m irked. I’m a child of the 1980s, when jocks ruled the high schools, and nerds were confined to the basement while the good ol’ boys slapped backs and made deals. When the bespectacled Bill Gates became the world’s richest person, something changed for the better, and I don’t want to go back to the old days. The tech backlash is just another situation where America needs to put aside its urge to turn inward and demonize some subset of the population. We should work to fix the problems associated with the industry, of course, but vitriol isn't the way to do it. The nerds are not the hosts of Mordor.
 Bryan Caplan arguably predicted much of this in his nerd/jock theory of history:
Notice: For financial success, the main measure where nerds now excel, governments make quite an effort to equalize differences. But on other margins of social success, where many nerds still struggle, laissez-faire prevails.
It's suspicious - and if you combine the Jock/Nerd Theory with some evolutionary psych, it makes sense. When the best hunter in the tribe gets rich, his neighbors will probably ask nicely for a share, if they dare to ask at all. But if the biggest nerd in the tribe gets rich, how long will it take before the jocks show up and warn him that "You'd better share and share alike"?
Punchline: Through the lens of the Jock/Nerd Theory of History, the welfare state doesn't look like a serious effort to "equalize outcomes." It looks more like a serious effort to block the "revenge of the nerds" - to keep them from using their financial success to unseat the jocks on every dimension of social status.
I'd love to see a version of Piketty that looks at inequality in dating success for those aged 16-25. Has that inequality gotten larger or smaller over time? Does anyone know? Does anyone other than the nerds care?

It wouldn't be hard to build a stylised case that social changes from the 1960s through to present that decoupled dating from marriage-search for the first decade of dating strongly benefited the jocks at the expense of the nerds. But we have no empirics on it. How would a Herfindahl dating concentration index change over time? Or a Gini coefficient?

Which inequalities matter is more interesting than what's going on on any particular margin of inequality.

Margins and averages: college edition

College grads earn more than those who don't go to college. Does it follow that governments should encourage more kids into university? Not necessarily. 

Bryan Caplan here points to work by Eberly and Athreya showing that while the college premium increased substantially, college enrolment did not. Why? Because mediocre students are likely to fail out, and the returns to dropping out of college aren't that high. Caplan summarises:
Let me illustrate.  Suppose you're at the 90th-percentile of high school graduates, so your probability of graduating college if you enroll is around 90%.  When the college premium ascends from 50% to 70%, your expected premium goes from 45% to 63%.  In plain English, the payoff goes from very good to excellent.  Either way, enrollment is a no-brainer.
If instead you're at the 25th-percentile of high school graduates, your probability of graduating college if you enroll is around 20%.  When the college premium ascends from 50% to 70%, your expected premium goes from 10% to 14%.  In plain English, the payoff goes from really crummy to crummy.  Either way, non-enrollment is a no-brainer... especially when you dwell on the fact that colleges don't refund drop-outs' tuition, much less the earnings and work experience they forfeited to attend.
 Bryan then looks to other "no-brainers":
My favorite feature of Eberly-Athreya: Their story readily generalizes to other weighty life choices widely seen as "no-brainers."  Conventional wisdom condemns dropping out of high school.  After all, standard estimates say that finishing high school raises your income by 50%.  For good students, it's easy money.  For stereotypical "bad students," though, it's hard money - or a waste of money.  Why?  Because when bad students attend high school, their probability of graduation - and their expected return - remains fairly low.
The same holds for marriage.  The economic benefits of stable marriage are massive.  But as Charles Murray explains, the probability of stable marriage varies widely by social class.  Divorce rates for the working class are about four times as high as for professionals.  Marginal brides and grooms therefore face a high probability of marital failure - and can reasonably fear that marriage will make them worse off despite its palpable benefits.
To be fair, Eberly and Athreya are not the first or only education researchers to highlight the chasm between ex ante and ex post returns to education.  But as far as I can tell, no one makes the logic clearer.  If anyone taunts, "So your kids should go to college, but other people's kids shouldn't," the honest answer is "Don't shoot the messenger - or his kids."  The numbers don't lie: College is a great investment for great students, a mediocre investment for mediocre students, and a bad investment for bad students.  
This mirrors what Wolfers and Stephenson have been saying about the returns to marriage: the decline in marriage among the poor comes down to its lower expected value for poor people.

I will leave as an exercise for the student the following problem. New Zealand recently changed the university funding model. Previously, universities were funded based on student numbers and research output. Now, they're also rewarded for their degree-completion rates: they're punished for drop-outs. What happens to:

  • equilibrium standards for passing grades
  • the average college premium
  • the absolute college premium for better students
  • the expected college premium for better students
  • the absolute college premium for worse students
  • the expected college premium for worse students

Migration beats activism

I agree with everything in Bryan Caplan's post. If you have the option to move away from an oppressive place, moving makes far more sense than trying to change the system. You're doing pointless harm to your family by staying.

Now imagine that you live in a place that, while pretty prosperous, has a whole lot of things you find oppressive. You spend a lot of time complaining about those things. Your sons stand a non-trivial chance of someday being drafted into the army or some kind of national service. While you don't find the laws against using drugs to be personally binding, there's the lowish probability risk of being subject to an erroneous no-knock armed police raid if the cops get something wrong. Cops kill people very often in these raids; at best, they just terrify your children. If you drive near the country's borders, the internal security police might stop you and demand your papers. There's the low but real risk that the cops will just decide to seize whatever cash you have with youThe schools are guarded like a prison camps. You like betting on odd claims; the local police in your county have a history of showing up at the front door of people who make bets and shooting them - this happened to a dentist just a few miles from your own house. And the police could use selections from your anarchist writings to ex post justify just about anything they decided to do, if you get the unlucky lotto ticket. If your kids screw up a bit when they're older or are even suspected of having done so (again, low but non-zero chance), the system's really pretty horrible. If one of your children messes up and sells drugs even once from your house (very very unlikely, but not impossible), the government can make you homeless.

While you're able to live most of the time unimpeded by this stuff in a bubble of like-minded friends, the random-draw risks are a bit worrying. You could kinda model it as living in a nice place, but with a small risk that you and your family will be the ones selected for some horrible annual ritual sacrifice. You never attend the annual sacrificial ritual despite its broad popularity; you instead do what you can to try and stop the ritual. Maybe you have more protection against being selected for the annual sacrifice ritual than do most folks because you're not really in the typically preyed-upon cohort, but that risk is still there. You pay your taxes, knowing that that money is taken to fund the annual sacrificial ritual.

Yes, the case for migrating out of really terrible third world places is definitely much much stronger than the case for moving out of Fairfax County. But still...

All joy no fun? You're failing.

Parenting is only "all joy and no fun" if you decide to run things that way. It's totally up to you. If you like that kind of thing, well, de gustibus. But know that it doesn't have to be that way, and especially so if all the doomsayers have put you off having kids.

Things we've done that make parenting fun.

  • The kids never got to see any TV shows we don't like so they don't ask for them. They get to choose among TV shows we do like. The Wiggles have never entered our house. We don't have Sky with insipid Disney cartoons. Instead, the kids get:
    • Classic episodes of Sesame Street
    • Animaniacs
    • Pinky and the Brain
    • Adventure Time
    • PowerPuff Girls
    • Samurai Jack
    • Classic Bugs Bunny
    • Freakazoid
  • The kids never get cutesy kid music that we don't like. They can choose among the things we do like. And, I spend time finding music that we'll all like. Like Dan Marcotte's brilliant Dungeons & Dragons kid-friendly tunes. My daughter demands "Jello Music" sometimes when we're driving. What's Jello Music? This is Jello Music. Songs sung by Jello Biafra. The kids love Weird Al Yankovic. Why oh Why are you listening to The Wiggles?
  • We buy books to read to them that we also like reading. Our son started into illustrated versions of The Hobbit, The Odyssey, and the Ring Cycle before he was 4. There are TONS of books that are great for both parents and kids. Shaun Tan works great. We've almost finished Eddings' Belgariad series. 
  • Audiobooks while commuting can be great too. StoryNory.com has, for free (donation recommended), great audio renditions of:
  • We play games with them that we also enjoy playing. You can totally run Dungeons & Dragons scenarios that work for 3 year olds if you don't expect that they'll be writing things down on their character sheets. Set up simple puzzle quests and see how they work them out. What could be more fun than that? They beg for me to run scenarios while we're commuting to and from daycare/school. Because of bad traffic, I sometimes have to turn down my childrens' pleading requests that we play Dungeons and Dragons in the car. My children have excess demand for Dungeons and Dragons. What could be better?
    • For a few months, when he was 5, the boy's favourite thing in the whole world was to play Skyrim with me. I'd play, he'd watch for monsters and point out things I should be doing. All joy, all fun. Then, when we'd go out to the park afterwards, we'd LARP Skyrim. He'd set up an alchemy table on a stump and we'd find things to mix together. Then we'd kill monsters with sticks. So long as you don't care about looking ridiculous, it's awesome. And ceasing caring about what other people think about stuff is a great general purpose technology anyway.
    • We've been playing 2-player Lego Batman. The three year old is almost old enough to handle a controller - I give it another couple of months. She's ridiculously good at solving some of the puzzles and giving advice as her brother and I go though. 
    • If he's good, I'll play Pocket Minecraft with him as LAN play. And if he saves up enough money from doing chores around the house, he'll be able to buy PC Minecraft for the machine in the living room. 
    • If you've forgotten how to have fun playing LEGO, are you sure that kids are right for you in the first place?
Yes, the first year's insomnia is awful. Toilet training is horrible. Feeding can be a disgusting mess. There's much tedious training required if you want to produce kids that others might find acceptable adults later on. But the fun stuff should be fun for both of you. I don't get people who decide to kill the fun stuff. What a horrible horrible pointless and stupid waste. There are little people in your house who would love to play Dungeons and Dragons with you, if only you would give them a chance.

Folks like Ruth Graham need to ignore all the whiny parents. A lot of it is just signalling from people who think that others will hold them in higher esteem because of all of the work they've put into parenting. Don't encourage this labour-theory-of-value-thinking by sympathising or awarding approbation. Read Bryan Caplan's serenity approach to parenting and have fun.

    Odd Japanese labour markets

    Am I the only one who read the various stories on impending social collapse in Japan and reckoned there to be a potentially large opportunity for a firm that would be happy to hire women on flex-time arrangements?

    Tyler pointed to one story yesterday; another hit the Washington Post today. Short version of both: Japanese labour markets are a disaster. Employers expect that a woman getting married has shifted to the mommy track and so pull her from opportunities for advancement, because she's likely to leave work after childbirth. And they're not wrong: the Guardian story says 70% of women leave work after having had a kid. Women wanting to have a career then don't get married.

    Suppose that were all that were going on. We'd then expect some clever firm would figure out that there are tons of qualified women itching to get back into the labour market on flex-time arrangements and would hire them on a compensation bundle including less salary, on-site daycare*, and flex-time. Further, the peculiarities of the Japanese labour market could really work to such a firm's advantage. If you expect that a firm will dump you post-kid, then you don't make relationship-specific investments with that firm pre-kid. If you expect that you can flip to a decent flex-time arrangement post-kid, you work much harder for the firm pre-kid. And while the "job for life" norm seems to be abating in Japan, I'd be surprised if it were less true there than elsewhere.

    So, why isn't this happening? First explanation: work norms. Where everyone's expected to put in really long hours, and where a firm has a mix of 16-hr workers and 7.5-hr workers, there's really no choice but to sideline the 7.5-hr workers onto the slow-track. But surely that's somewhat question-begging: it seems pretty improbable that you get that more output from one worker on 16-hour days than from two workers each on 8-hour days (who are on the same hourly but different annual total pay). And even if the 16-hour worker is more productive than two 8-hour workers, you could then just pay the 8-hour worker proportionately less.

    Next explanation: The Guardian says kids are unaffordable unless you're on two incomes, but it's impossible to be on two incomes. Tokyo's expensive, but it's not the world's least affordable place. Beijing, Rome, Mumbai, London and Paris all come out worse on this index. But, where that index is conditioned on disposable incomes, and where salaries are based on crazy-long hours, then affordability could be a serious issue for those wanting to move to sane work hours. Maybe this part starts sorting itself out as homeowners die off faster than houses depreciate. Housing prices then fall rapidly as supply starts exceeding the number of people.

    I can imagine a story where tight space constraints in Tokyo combined with pretty strong work norms have folks bidding up housing prices until it's pretty tough to afford a spot big enough for a family without two incomes with long work hours. But that story then conflicts with survey data that has money and housing as trivial reasons for not marrying; the Post story reports instead that "Do not feel the necessity" and "Do not want to lose freedom or comfort" were the main reasons given by both sexes for not marrying. And wanting to enjoy hobbies or entertainment was a slightly more commonly given reason for not marrying than wanting to concentrate on work or studies.

    Maybe we need a Japanese translation of Bryan Caplan's book on low-effort parenting. The integral under the kid marginal-benefit curve is a lot bigger if you figure out ways of continuing to enjoy freedom and comfort.

    Update: Brennan MacDonald points out that visas for domestic guest workers are much more difficult in Japan than in Singapore; if it's much harder to get a nanny, then that too helps explain female labour supply differences.


    * Daycare availability seems a serious problem.
