The new school choice debate (a child is more than just a test score)
Since Donald Trump has picked Betsy DeVos to be education secretary, many commentators have been pulling out their anti-school choice arguments from the closet, and for the most part it isn’t a pretty sight. To insist on a single government-run school and trash school choice, while out of the other side of one’s mouth criticizing Trump for “authoritarianism,” and other times proclaiming “Black Lives Matter” is from my point of view a pretty poor mix.
To be sure, we’re still not sure how well vouchers work, and I would suggest continuing experimentation rather than full-on commitment. Frankly, I find a lot of the voucher advocates unconvincing, but let’s not forget the single most overwhelming (yet neglected) empirical fact about vouchers: they improve parent satisfaction.
That result is not much contested. For instance:
Universally, school choice parents are highly satisfied with choice schools, reporting greater discipline, more responsive staff and better educational environments than the public schools they left. That parents are satisfied with their choice schools is a valuable indicator that school choice delivers real benefits. As University of Wisconsin professor John Witte, the official evaluator of the Milwaukee choice program, recently commented on school choice research: “There’s one very consistent finding: Parental involvement is very positive, and parental satisfaction is very positive…parents are happier. The people using vouchers are mostly black and Hispanic and very poor…they deserve the same kind of options that middle-class white people have.”
Patrick J. Wolf’s survey of twelve voucher programs (pdf) supports this interpretation. And here are strongly positive results on parental satisfaction Indiana. I could go on, but I don’t think there is much need.
Of course parents may like school choice for reasons other than test scores. To draw from the first link above, parents may like the academic programs, teacher skills, school discipline, safety, student respect for teachers, moral values, class size, teacher-parent relations, parental involvement, and freedom to observe religious traditions, among other facets of school choice.
Perhaps now is the time to remind you that how the buyers like the product is the fundamental standard used by economists for judging public policy? That is not to say it is the final standard all things considered, but surely economists should at least start here and report positive parental satisfaction as a major feature of school choice programs. In fact, I’ll say this: if you’re reading a critique of vouchers and the critic isn’t willing to tell you up front that parents typically like this form of school choice, I suspect the critic isn’t really trying to inform you.
To be sure, you still might not favor school vouchers. You might think they cost too much, you might think they will politicize private schools too much, or you might think they weaken national unity too much, to cite a few possibilities. (Although please, on that latter matter you can’t just say something silly like “public schools and the army made America what it is today.” You need some actual evidence. Won’t parents who are happy with the schooling of their children also contribute to national unity and push us away from polarization? That effect might outweigh whatever more negative mechanism you have in mind. Evidence please, not just sentiment.)
And as for test scores, the evidence there is still unclear. Here are a few earlier MR posts, no cherry- or lemon-picking, please.
Scott Alexander has some excellent comments on vouchers and school choice.
Best movies of 2016
45 Years, British drama about a creaky marriage.
The Boy & the World. A Brazilian animated movie, it actually fits the cliche “unlike any movie you’ve seen before.” Preview here, other links here, good for niños but not only. Excellent soundtrack by Nana Vasconcelos.
The Second Mother. A Brazilian comedy of manners about social and economic inequality, as reflected in the relations between a maid, her visiting daughter, and the maid’s employer family. Now, to my and maybe your ears that sounds like poison, because “X is about inequality” correlates strongly with “X is not very good,” I am sorry to say. This movie is the exception, subtle throughout, and you can watch and enjoy it from any political point of view. It helps to know a bit about Brazil, and it takes about twenty minutes for the core plot to get off the ground. Links here.
Cemetery of Splendor, Thai movie by Apichatpong Weerasethakul, here is a good review.
City of Gold, a documentary with Jonathan Gold doing the ethnic food thing in Los Angeles.
Hunt for the Wilderpeople is an original movie, mostly about race, full of cinematic allusions (LOTR, First Blood, Smash Palace, classic Westerns, Butch Cassidy, Thelma and Louise, so many more) and Kiwi finery as well. None of the reviews I read seem to get it and I don’t want to send you to any of them.
The Innocents, how did those Polish nuns get pregnant?
Maggie’s Plan, a fun comedy, not at the top of this list but intelligent comedies are a dwindling species.
Ixcanul, a Mayan movie from Guatemala, might this story of an unwanted pregnancy be this year’s best movie? Here is one useful review.
Sausage Party, beyond politically incorrect, I kept on thinking I would get sick of the stupid animation and yet I never did. I remain surprised they let this one play in mainstream theaters.
Sully. He should have turned the plane around immediately under any plausible calculus, and he didn’t, so you have to give this movie the Straussian reading.
Weiner is a splendid movie with many subtle points, including in the philosophical direction. In another life, Huma Abedin could have been a movie star. She has exactly the right mix of distance and involvement, and she dominates every scene she is in, even when just sitting quietly in the background. Um…I guess she is a movie star. Starlet. Whatever.
Difret, an Ethiopian legal drama.
Andrei Tarkovsky, Ivan’s Childhood (reissue). This is one of Tarkovsky’s worst movies, and yet one of the best movies in virtually any year.
The Handmaiden, by Park Chan-wook. Imperfectly eroticized violence, but beautiful nonetheless.
Elle, by Paul Verhoeven.
Nocturnal Animals, by Tom Ford.
The bottom line
My top picks are Ixcanul, American Honey, Hunt for the Wilderpeople, Cemetery of Splendor, and Sky Ladder, with Arrival being the best mainstream Hollywood movie.

The effects of public unions on compensation
I can’t say I followed this debate very closely, still this paper may settle some of the outstanding questions about public sector unions and wages and bargaining power.
The Effects of Public Unions on Compensation: Evidence from Wisconsin (Job Market Paper)
This paper seeks identify the effect that public sector unions have on compensation. Specifically, I look at the compensation premium associated with teachers’ unions in Wisconsin. In 2011, Wisconsin passed a landmark law (Act 10) which significantly lowered the bargaining power of all public sector unions in the state. Using an event study framework, I exploit plausibly exogenous timing differences based on contract renewal dates, which caused districts to be first exposed to the new regulations in different years. I find that the reduction in union power associated with Act 10 reduced total teacher compensation by 8%, or $6,500. Roughly two-thirds of this decline is driven through reduced fringe benefits. The analysis shows that the most experienced and highest paid teachers benefit most from unionization. I supplement the event study approach with synthetic control and regression discontinuity methods to find that regulatory limits on contract terms, rather than other mechanisms such as state financial aid cuts or union decertification, are driving the results.

New Zealand to Compensate Organ Donors
New Zealand will now compensate live organ donors for all lost income:
Today’s unanimous cross-party support for the Compensation for Live Organ Donors Bill represents a critical step in reducing the burgeoning waiting list for kidney donations, according to Kidney Health New Zealand chief executive Max Reid.
“The Bill effectively removes what is known to be one of the single greatest barriers to live organ donation in NZ,” Mr Reid says. “Until now the level of financial assistance (based on the sickness benefit) has been insufficient to cover even an average mortgage repayment, and the process required to access that support both cumbersome and demeaning. The two major changes that this legislation introduces – increasing compensation to 100% of lost income, and transferring responsibility for the management of that financial assistance being moved from WINZ to the Ministry of Health – will unquestionably remove two major disincentives that exist within the current regime.”
Eric Crampton (former GMU student, now NZ economist who supported the bill) notes that a key move in generating political support was that New Zealand MP Chris Bishop framed the bill as compensating donors for lost wages rather than paying them. A decrease in the disincentive to donate–an increase in the incentive to donate. To an economist, potato, potato. But for people whose kidneys fail in New Zealand, the right framing may have been the difference between life and death.
This is also a good time to remind readers of Held, McCormick, Ojo and Roberts, A Cost-Benefit Analysis of Government Compensation of Kidney Donors published in the American Journal of Transplantation.
From 5000 to 10 000 kidney patients die prematurely in the United States each year, and about 100 000 more suffer the debilitating effects of dialysis, because of a shortage of transplant kidneys. To reduce this shortage, many advocate having the government compensate kidney donors. This paper presents a comprehensive cost-benefit analysis of such a change. It considers not only the substantial savings to society because kidney recipients would no longer need expensive dialysis treatments—$1.45 million per kidney recipient—but also estimates the monetary value of the longer and healthier lives that kidney recipients enjoy—about $1.3 million per recipient. These numbers dwarf the proposed $45 000-per-kidney compensation that might be needed to end the kidney shortage and eliminate the kidney transplant waiting list. From the viewpoint of society, the net benefit from saving thousands of lives each year and reducing the suffering of 100 000 more receiving dialysis would be about $46 billion per year, with the benefits exceeding the costs by a factor of 3. In addition, it would save taxpayers about $12 billion each year.
Carlsen > Karjakin
1. Karjakin played some of the best defensive chess ever, finding resources where there appeared to be none.
2. Carlsen had become a bit lazy, relying too much on his stamina advantage to beat opponents (yes I do understand that is an odd notion of lazy!). Yet he had no real stamina advantage over Karjakin, who is of the same age and came to the match in very good physical shape. So Carlsen simply could not grind him down, and it took Carlsen the entire match to realize that.
3. Karjakin made very few attempts to achieve demonstrable, sharp advantages. That limited his total number of victories to one.
4. In the rapid tie-breaker — four consecutive games in the final day — Carlsen couldn’t try to win on stamina and simply showed he was the better player across many dimensions of the game. Karjakin posed him no problems at all in these contests.
5. Karjakin played as Carlsen’s equal for the twelve regular time control games. Yet I don’t think he will be back as a challenger. His style is too “drab” (Kasparov’s description) to get through all of the risk-rewarding tournaments to reach the final championship match again.
6. Perhaps rapid chess is the future of chess as a spectator sport. Four games in a row, each twenty-five minutes per player, plus increments. It was thrilling, and I watched on the train.
7. Putin finally lost one this year, let’s hope this reverses the trend.
Here is the Chessbase account, here is the quite good NYT story.
The Intel anthropologist on why we are afraid of AI
Here is a separate bit from that interview:
I’m interested in how animals are connected to the internet and how we might be able to see the world from an animal’s point of view. There’s something very interesting in someone else’s vantage point, which might have a truth to it. For instance, the tagging of cows for automatic milking machines, so that the cows can choose when to milk themselves. Cows went from being milked twice a day to being milked three to six times a day, which is great for the farm’s productivity and results in happier cows, but it’s also faintly disquieting that the technology makes clear to us the desires of cows – making them visible in ways they weren’t before. So what does one do with that knowledge? One of the unintended consequences of big data and the internet of things is that some things will become visible and compel us to confront them.
And on the main question at hand:
What we are seeing now isn’t an anxiety about artificial intelligence per se, it’s about what it says about us. That if you can make something like us, where does it leave us?

Which kind of countercyclical fiscal policy is best?
Miguel Faria-e-Castro, on the job market from NYU, has a very interesting paper on that question. Here are his findings:
What is the impact of an extra dollar of government spending during a financial crisis? How important was fiscal policy during the Great Recession? I develop a macroeconomic model of fiscal policy with a financial sector that allows me to study the effects of fiscal policy tools such as government purchases and transfers, as well as of financial sector interventions such as bank recapitalizations and credit guarantees. Solving the model with nonlinear methods allows me to show how the linkages between household and bank balance sheets generate new channels through which fiscal policy can stimulate the economy, and study the state dependent effects of fiscal policy. I combine the model with data on the fiscal policy response to assess its role during the financial crisis and Great Recession. My main findings are that: (i) the fall in consumption would had been 1/3 worse in the absence of fiscal interventions; (ii) transfers to households and bank recapitalizations yielded the largest fiscal multipliers; and (iii) bank recapitalizations were closest to generating a Pareto improvement.
Bank recapitalizations — just remember that the next time you hear someone talking about “G” in the abstract.

In 2002, George Washington University President Stephen Trachtenberg noticed that the school owned roughly $1 billion worth of facilities that sat idle for at least a third of the year. If he could reconfigure the academic calendar for year-round operation, he reasoned, he could enroll thousands more students without having to build new classrooms, labs, dorms or athletic facilities.
Doing so, however, would have required some professors to periodically teach during the summer, which didn’t sit well with the Faculty Senate. Its report on the matter reads like a parody of self-interested whining by coddled academics dressed up as concern for the pedagogical and psychological well-being of their students.

Airport Privatization
Airports in the United States need investment and improvements in operations efficiency and are thus ripe for privatization. Privatization is not a radical concept, around the world today many airports are run by private corporations or in public-private partnerships. In their latest report, The Ownership of Europe’s Airports, the Airports Council International writes:
Today, over 40% of European airports have at least some private shareholders – and these airports handle the lion’s share of air traffic. This year, about 3 out of every 4 passenger journeys will be through one of these airports…it is only a matter of time before fully publically-owned airports become a minority in the EU.
Moreover, even the public airports are typically structured as corporations that must pay their own way:
[Europe’s] airports – be they public or private – are to be run as businesses in their own right, strongly incentivised to continuously improve and underpinned by the principle that users pay a reasonable price to cover the cost of providing the facilities and services that they benefit from. There is no denying the tangible benefits that this approach has brought the EU – significant volumes of investment in necessary infrastructure, higher service quality levels, and a commercial acumen which allows airport operators to diversify revenue streams and minimise the costs that users have to pay – all of which are fundamental requirements to boost air connectivity.
The biggest restriction on airport privatization is that if a state or local government sells an airport it must use all of the proceeds to fund airport infrastructure–which makes the procedure pointless from their point of view. As I mentioned earlier, there is an Airport Privatization Pilot Program (APPP) which lifts this restriction but only if 65% of the air carriers serving the airport agree to the privatization. The APP is also slow and includes other restrictions. The Congressional Research Service has a good run down.
[Restrictions] include the need for 65% of air carriers serving the airport to approve a lease or sale of the airport; restrictions on increases in airport rates and charges that exceed the rate of increase of the Consumer Price Index (CPI), and a requirement that a private operator comply with grant assurances made by the previous public sector operator to obtain AIP [Federal] grants. In addition, after privatization the airport will be eligible for AIP formula grants to cover only 70% of the cost of improvements, versus the normal 75%- 90% federal share for AIP projects at publicly owned airports. This serves as a disincentive to privatize an airport, because it will receive less federal money after privatization.
The airlines are lukewarm on privatization. Although they would benefit from better operational efficiency, they are big recipients of the explicit and implicit subsidies and they use their effective control over airports to limit competition.
The main danger of privatization is that of monopoly power–it wouldn’t be a good idea to sell all of a city’s airports to the same corporation, for example. Thus, privatization should be accompanied by steps to increase competition. There are over 5000 non-commercial airports in the United States and some of the “National” General Aviation Airports already serve international flights (mainly corporate jets) and could be expanded to allow more commercial traffic.
Privatization should not be thought of as just a transfer of ownership but rather as a changing of the rules of the game to allow for many more private airports.

Upward Mobility and Discrimination: Asians and African Americans
Asians in America faced heavy discrimination and animus in the early twentieth century. Yet, after institutional restrictions were lifted in the late 1940s, Asian incomes quickly converged to white incomes. Why? In the politically incorrect paper of the year (ungated) Nathaniel Hilger argues that convergence was due to market forces subverting discrimination. First, a reminder about the history and strength of discrimination against Asians:
Foreign-born Asians were barred from naturalization by the Naturalization Act of 1790. This Act excluded Asians from citizenship and voting except by birth, and created the important new legal category of “aliens ineligible for citizenship”…Asians experienced mob violence including lynchings and over 200 “roundups” from 1849-1906 (Pfaelzer, 2008), and hostility from anti-Asian clubs much like the Ku Klux Klan (e.g., the Asiatic Exclusion League, Chinese Exclusion League, Workingmen’s Party of CA), to an extent that does not appear to have any counterpart for blacks in CA history. Both Asians and blacks in CA could not testify against a white witness in court from 1853-73 (People v. Hall, 1853, see McClain, 1984), limiting Asians’ legal defense against white aggression. The Chinese Exclusion Act of 1882 and the “Gentlemen’s Agreement” in 1907 barred further immigration of all “laborers” from China and Japan.
…Asians have also faced intense economic discrimination. Many cities and states levied discriminatory taxes and fees on Asians (1852 Foreign Miner’s Tax, 1852 Commutation Tax, 1860 Fishing License, 1862 Police Tax, 1870 “queue” ordinance, 1870 sidewalk ordinance, and many others). Many professional schools and associations in CA excluded Asians (e.g., State Bar of CA), as did most labor unions (e.g., Knights of Labor, American Federation of Labor), and many employers declined to hire Asians well into the 20th century (e.g., Mears, 1928, p. 194-204). From 1913-23, virtually all western states passed increasingly strict Alien Land Acts that prohibited foreign-born Asians from owning land or leasing land for extended periods. Asians also faced laws against marriage to whites (1905 amendment to Section 60 of the CA Civil Code) and U.S. citizens (Expatriation Act 1907, Cable Act 1922). From 1942-46, the US forcibly relocated over 100,000 mainland Japanese Americans (unlike other Axis nationalities, e.g. German or Italian Americans) to military detention camps, in practice destroying a large share of Japanese American wealth. In contrast, blacks in CA were eligible for citizenship and suffrage, were officially (though often not de facto) included in CA professional associations and labor unions that excluded Asians, were not covered by the Alien Land Acts, and were not confined or expropriated during WWII.
Despite this intense discrimination, Asian (primarily Japanese and Chinese) incomes converged to white incomes as early as 1960 and certainly by 1980. One argument is that Asians invested so heavily in education that convergence has been overstated but Hilger shows that convergence occurred conditional on education. Similarly, convergence was not a matter of immigration or changing demographics. Instead, Hilger argues that once institutional discrimination was eased in the 1940s, market forces enforced convergence. As I wrote earlier, profit maximization subverts discrimination by employers:
If the wages of X-type workers are 25% lower than those of Y-type workers, for example, then a greedy capitalist can increase profits by hiring more X workers. If Y workers cost $15 per hour and X workers cost $11.25 per hour then a firm with 100 workers could make an extra $750,000 a year. In fact, a greedy capitalist could earn more than this by pricing just below the discriminating firms, taking over the market, and driving the discriminating firms under.
If that theory is true, however, then why haven’t black incomes converged? And here is where the paper gets into the politically incorrect:
Modern empirical work has indicated that cognitive test scores—interpreted as measures of productivity not captured by educational attainment—can account for a large share of black-white wage and earnings gaps (Neal and Johnson, 1996; Johnson and Neal, 1998; Fryer, 2010; Carruthers and Wanamaker, 2016). This literature documents large black-white test score gaps that emerge early in childhood (Fryer and Levitt, 2013), persist into adulthood, and appear to reflect genuine skills related to labor market productivity rather than racial bias in the testing instrument (Neal and Johnson, 1996). While these modern score gaps
have not been fully accounted for by measured background characteristics (Neal, 2006; Fryer and Levitt, 2006; Fryer, 2010), they likely relate to suppressed black skill acquisition during slavery and subsequent educational discrimination against blacks spanning multiple generations (Margo, 2016).
…A basic requirement of this hypothesis is that Asians in 1940 possessed greater skills than blacks, conditional on education. In fact, previous research on Japanese Americans in CA support this theory. Evidence from a variety of cognitive tests given to students in CA in the early 20th century suggest test score parity of Japanese Americans with local whites after accounting for linguistic and cultural discrepancies, and superiority of Japanese Americans in academic performance in grades 7-12 (Ichihashi, 1932; Bell, 1935).
Hilger supplements these earlier findings with a small dataset from the Army General Classification Test:
…these groups’ cognitive test performance can be studied using AGCT scores in WWII enlistment records from 1943. Remarkably, these data are large enough to compare Chinese, blacks and whites living in CA for these earlier cohorts. In addition, this sample contains enough young men past their early 20s to compare test scores conditional on final educational attainment, which can help to shed light on mechanisms underlying the conditional earnings gap documented above.
Figure XII plots the distribution of normalized test score residuals by race from an OLS regression of test z-scores on dummies for education and age. Chinese Americans and whites have strikingly similar conditional skill distributions, while the black skill distribution lags behind by nearly a full standard deviation. Table VIII shows that this pattern holds separately within broad educational categories. These high test scores of Chinese Americans provide strong evidence that the AGCT was not hopelessly biased against non-whites, as Neal and Johnson (1996) also find for the AFQT (the successor to the AGCT) in more recent cohorts.
From Hilger’s conclusion:
Using a large and broadly representative sample of WWII enlistee test scores from 1943 both on their own and matched to the 1940 census, I document the striking fact that these test scores can account for a large share of the black, but not Asian, conditional earnings gap in 1940. This result suggests that Asians earnings gaps in 1940 stemmed primarily from taste-based or some other non-statistical discrimination, in sharp contrast with the black earnings gap which largely reflected statistical discrimination based on skill gaps inherited from centuries of slavery and educational exclusion. The rapid divergence of conditional earnings between CA-born Asians and blacks after 1940—once CA abandoned its most severe discriminatory laws and practices—provides the first direct empirical evidence in support of the hypothesis of Arrow (1972) and others that competitive labor markets tend to eliminate earnings gaps based purely on taste-based but not statistical discrimination.
Hilger’s other research is here.
Unsexy Infrastructure: Lock and Dam
The NYTimes has a good piece on dam infrastructure:
Built in 1929, Lock No. 52 sits in a quiet corner of southern Illinois that happens to be the busiest spot on America’s inland waterways, where traffic from the eastern United States meets and passes traffic from the Gulf Coast and the Mississippi River. More than 80 million tons of grain, coal, fuel and other goods — worth over $22 billion — move through here each year.
The problem is that the old dam is crumbling and a new one is way behind schedule:
The average delay at No. 52 in October and November was 15 to 20 hours. At the moment, No. 52’s sister dam downriver, No. 53, is adding 48 more hours to the wait.
Dealing with both dams, it can take five days to travel just 100 miles on this stretch of the Ohio River.
It’s not just dams, there is a lot of room for relatively simple infrastructure projects which aren’t sexy like high-speed rail but are valuable. As I wrote in 2012 (no indent):
Rail congestion in Chicago, for example, is so bad that freight passing through Chicago often slows down to less than the pace of an electric wheel chair. Improvements are sometimes as simple as replacing 19th century technology with 20th century (not even 21st century!) technology. Even today (2012, improvements are being made, albeit slowly AT), for example:
…engineers at some points have to get out of their cabins, walk the length of the train back to the switch — a mile or more — operate the switch, and then trudge back to their place at the head of the train before setting out again.
In a useful article Phillip Longman points out that there are choke points on the Eastern Seaboard which severely reduce the potential for rail:
…railroads can capture only 2 percent of the container traffic traveling up and down the eastern seaboard because of obscure choke points, such as the Howard Street Tunnel in downtown Baltimore. The tunnel is too small to allow double-stack container trains through, and so antiquated it’s been listed on the National Register of Historic Places since 1973. When it shut down in 2001 due to a fire, trains had to divert as far as Cincinnati to get around it. Owner CSX has big plans for capturing more truck traffic from I-95, and for creating room for more passenger trains as well, but can’t do any of this until it finds the financing to fix or bypass this tunnel and make other infrastructure improvements down the line. In 2007, it submitted a detailed plan to the U.S. Department of Transportation to build a steel wheel interstate from Washington to Miami, but no federal funding has been forthcoming.
Longman points out that:
Railroads have gone from having too much track to having not enough. Today, the nation’s rail network is just 94,942 miles, less than half of what it was in 1970, yet it is hauling 137 percent more freight, making for extreme congestion and longer shipping times.
…. And it’s not just rail, sewers and the water supply are another example. Consider:
The average D.C. water pipe is 77 years old, but a great many were laid in the 19th century. Sewers are even older. Most should have been replaced decades ago.
Does that sound like the infrastructure of an advanced nation?
have not been fully accounted for by measured background characteristics (Neal, 2006; Fryer and Levitt, 2006; Fryer, 2010), they likely relate to suppressed black skill acquisition during slavery and subsequent educational discrimination against blacks spanning multiple generations (Margo, 2016).
