How to get stuff done

This is a good discussion, I agree with most of it, for most people.  Here is one bit:

The hardest part is often just starting. I’ve found that it’s especially hard for me to start when a task is difficult or complex. The more importance and weight a certain activity has in my life or business, the more I seem to put off starting.

However, if I can just get moving on it, even for a few minutes, it tends to get easier.

Because I know this about myself, rather than setting the intention to finish something, I resolve myself to start. The more often I start, the easier things get finished. Overcoming that first bit of inertia is the biggest challenge (just like getting started on a run, or the first push of getting a car moving).

Once things are moving, momentum is on your side.

That is from Jonathan Mead, hat tip goes to Anya Kamenetz.  You also can enter “time management” into the MR search function, and then scroll down a bit.

The shift to on-line education can happen gradually and easily

I left the following comment on Bryan Caplan’s blog post:

You don’t need to overturn all convention.  The top schools could shift at the margin, as they have many times in the past, and suddenly the conformist thing to do is to have ?? percent of your classes be on-line, and so on.  In virtually any other context you would see the flexibility of the market here!  No major credentials need to collapse, if it turns out that cannot happen easily.

This is a phantom issue, raised by many people but not thought through deeply enough.  Markets convexify (sometimes).

It is fine to argue “on-line education is not in fact more efficient.”  It is much harder to argue “if it is efficient, conformity pressures will keep it out of the market.”  Don’t confuse the former case with the latter.

Why is U.S. higher education so dominant? And why is Harvard #1?

Shailendra Raj Mehta reports:

The key innovation was alumni control of the Board of Trustees. This is what made possible several desiderata on the Rosovsky (1991) and (Aghion, Dewatripont et al. 2007) lists in the first place. This is what simultaneously allowed autonomy, continuity of purpose, large  endowments and the ability to weather turbulence. The role of alumni trustees has not been fully examined so far. Now, to be sure, Rosovsky does talk about the role of independent trustees. Certainly it is true that in one sense the trustees of US schools are often truly independent in that they provide a buffer against interference from the political and other domains. Further, they are usually able to take a view of the institution independent of the interests of the faculty. But, in fact, the trustees are not independent or uninterested observers at all. This is on account of the fact that the Board of Trustees, at least in the top US schools, consists primarily of alumni, the group which has the highest permanent stake in the reputation of the university.

…Therefore, whichever measure of school quality that we use – rank, school selectivity or endowment, we find that same result – the greater the degree of alumni control, the higher the quality of the school.

…so why is Harvard #1? This question, then becomes easy to answer. Except for a few brief years in its early days and a decade in the middle, for almost its entire existence, a period of nearly 400 years, Harvard has been controlled by its alumni.

The paper is here (pdf), interesting throughout.

Bryan Caplan’s signaling model and on-line education

The very useful model is here, and there is further commentary from Bryan here.  My question is this: does the model imply that on-line education should succeed, or not?

Let’s say that education signals conscientiousness.  A purely on-line class, with no ogre standing over your shoulder to discipline you, should be blown off by those who are not conscientiousness.  The on-line class would seem to offer a better signal and a cleaner separation of types.

Alternatively, let’s say education signals IQ or some other notion of “smarts.”  On-line education would seem to offer less opportunity to get through by buttering up the teacher, spouting mumbo-jumbo in basket-weaving classes, and so on.  For better or worse, a lot of on-line education seems to be based on relatively objective tests.  Then on-line education would seem to offer a better signal of smarts.

One possible application of Bryan’s model might be this.  Income inequality is rising, so there is greater care to get the signal, selection, and screening right for top jobs.  Relatively high levels of education should be all the more discriminatory, and that may mean more on-line education.  In fact, in normative terms that might well be a problem with on-line education, namely its inegalitarian nature with regard to curiosity and effort and smarts.

Oddly, the signaling model could be true, but through an invisible hand mechanism — schools competing to separate quality in the most effective ways — you can end up with a state of affairs where upfront signaling costs are fairly low.  Imagine a chess school, needing to sort talent, and unable to teach its students very much, but setting up a quite cheap on-line tournament and declaring some winners.  Aren’t the Khan Academy users some really talented people?

Alternatively, through an invisible hand mechanism, if the learning model is correct, you could end up with an equilibrium in which upfront signaling costs appear to be relatively high, namely that you impose “taxes” to make sure people end up learning what they need to know.  Think Paris Island or KIPP schools.

It is important not to confuse “seeing high upfront signaling costs” with “the signaling model of education is essentially correct.”  They sound like they should go together, but quite possibly they don’t.

Will Fairfax follow through with The Great Experiment?

Fairfax County schools could become the first in the Washington region to create a virtual public high school that would allow students to take all their classes from a computer at home.

No sports teams. No pep rallies. No lockers, no hall passes. Instead, assignments delivered on-screen and after-school clubs that meet online.

It’s a reimagination of the American high school experience. And it’s a nod to the power of the school choice movement, which has given rise to the widespread expectation that parents should have a menu of options to customize their children’s education.

Several School Board members, who will hear a formal proposal for the online school at a meeting Monday, said they are excited by the prospect.

The full story is here.

The peculiar case of higher education

Via a request from Ezra for topic coverage, here are some very good remarks from Ryan Avent.  Excerpt:

A sector dominated by the state—state-run in some cases, merely subsidised and regulated in others—is, I think most Americans would agree, both a major contributor to American prosperity and one of America’s most competitive industries on foreign markets, despite its glaring inefficiencies. What ought we to conclude based on this example?

Certainly, one could reasonably argue that the sector would be even better if state control were relaxed, monopolies broken up, subsidies curtailed, and market controls (like those on immigration) eliminated. But one also has to wrestle with how different the American economy would look if the state had never muscled public universities (including a broad network of technology-driven, extension-oriented schools) into existence.

This stuff is harder than we often pretend.

A few observations:

1. Postwar higher education has proven one of America’s most effective subsidies, and it has paid for itself many times over.  It is also one of the more significant successes of federalism.

2. We are fortunate that U.S. state universities are more or less autonomous, compared to the Continental model where professors and administrators are treated as part of the state civil service bureaucracy.  The latter system does not work well, and those countries have struggled to move closer to American models.

3. To refer back to a distinction from the David Brooks column, we should not be trying to squeeze the entire economy into the shoebox of the dynamic but risky “Economy I.”  For public choice reasons, as well understood by Karl Polanyi (an underrated public choice theorist if there ever was one), the polity requires some respite from Economy I, whether we like that or not.  Read also this analysis by Interfluidity, which is one of my favorite blog posts of all time.  Furthermore the more “sluggish” Economy II, by operating under different principles, often serves as a useful R&D lab for Economy I.  Think MIT and Stanford, or note that Adam Smith ended up as a customs commissioner, as his father had been.  Goethe and Bach worked for governments for much of their lives.  It’s about balance and synergy, though it is perfectly fair to see contemporary Western Europe, especially in the periphery, as a region which has far too much Economy II and too little Economy I.

4. Maintaining the truth of #1 will prove a significant challenge going forward.  It’s not about blaming the critics or defunders of state universities, or the critics of public subsidies to private universities.  The real problems are a few.  First, successful state programs tend to stultify and decline over time, and if nothing else the danger is that health care costs will eat up state budgets.  Second, the absolute returns to higher education (as opposed to the wage for not going) are not currently high enough to maintain the current fiscal structure of those institutions, furthermore those fiscal structures do not have so much “give,” due to tenure and various self-imposed cost inflexibilities.  Third, although most state universities have relatively little explicit debt, they are implicitly massively leveraged through reliance on ongoing tuition boosts, ongoing enrollment boosts, and timely retirements, none of which can be counted on in the future.

It will prove a daunting path forward.

Ahem…

The study, funded by the William and Flora Hewlett Foundation, compared the software-generated ratings given to more than 22,000 short essays, written by students in junior high schools and high school sophomores, to the ratings given to the same essays by trained human readers.

The differences, across a number of different brands of automated essay scoring software (AES) and essay types, were minute. “The results demonstrated that over all, automated essay scoring was capable of producing scores similar to human scores for extended-response writing items,” the Akron researchers write, “with equal performance for both source-based and traditional writing genre.”

“In terms of being able to replicate the mean [ratings] and standard deviation of human readers, the automated scoring engines did remarkably well,” Mark D. Shermis, the dean of the college of education at Akron and the study’s lead author, said in an interview.

The Chicago School

In Launching the Innovation Renaissance I wrote:

In the United States, “vocational” programs are often thought of as programs for at-risk students, but that’s because they are taught in high schools with little connection to real workplaces. European programs are typically rigorous because the training is paid for by employers who consider apprentices an important part of their current and future work force. Apprentices are therefore given high-skill technical training that combines theory with practice—and the students are paid!

In the United States there are some experimental programs moving in this direction. One of the most interesting is being pushed by Chicago mayor Rahm Emanuel:

Chicago Public Schools (CPS) students will have the opportunity to attend five Early College STEM Schools (ECSS) that focus on technology skills and career readiness – as well as earn college credits– under a partnership agreement with five technology companies, CPS and City Colleges of Chicago, Mayor Rahm Emanuel announced…

The five technology companies, IBM, Cisco, Microsoft Corporation, Motorola Solutions and Verizon Wireless, will help develop a unique curriculum at each new school to teach students the skills required in that marketplace, as well as provide mentors and internships.  Upon graduating from these tailored programs, the students will be prepared for careers in science and technology.

…All of the new schools will open in September 2012 with a class of ninth graders.  Each student will be able to graduate in four-years with a high school diploma with college credits, with a goal of graduating within six years with an Associate of Science (AS) degree in Computer Science or an Associate in Applied Science (AAS) in Information Technology. The college courses will be taught by professors from CCC.

Emanuel is also redesigning the City Colleges of Chicago along similar lines:

Rahm fired almost all the college presidents, hired replacements after a national search, and decreed that six of the seven city-run colleges would have a special concentration. Corporations pledging to hire graduates will have a big hand in designing and implementing curricula. “You’re not going for four years, and you’re not going for a Nobel Prize or a research breakthrough,” he says. “This is about dealing with the nursing shortage, the lab-tech shortage. Hotels and restaurants will take over the curriculum for culinary and hospitality training.” Already AAR, a company that has 600 job openings for welders and mechanics, is partnering with Olive-Harvey College; Northwestern Memorial Hospital is designing job training in health care for Malcolm X College.

It’s too early to judge these developments but Emanuel’s op-ed on this subject was surprisingly good. The key question, which I haven’t yet seen answered, is whether the the companies will have real skin in the game, which I see as critical to success.

A sobering thought

The United States circa 2012 is one of the most productive economies of all time, arguably the most productive if you take into account size and diversification (rules out Norway, etc.).  Internationally speaking, in the richest and most productive global economy of all time, which is our most competitive sector?

Hollywood?  Maybe, but it could well be higher education.  Students from all over the world want to go to U.S. higher education.  If we had nicer immigration authorities, this advantage would be all the more pronounced.

In other words, I work in what is perhaps the most competitive and successful sector in the most competitive and successful economy of all time.

And yet what I see around me is a total, total mess.  And I believe my school to be considerably above average in terms of how well it is run.

Indian education under the British empire

It turns out it was worse than I had thought.  I’ve been reading some papers by Latika Chaudhary on this topic, and I learned that educational expenditures in India, under the British empire, never exceeded one percent of gdp.  To put that in perspective, for 1860-1912 in per capita terms the independent “Princely states” were spending about twice as much on education as India under the British.  Mexico and Brazil, hardly marvels of successful education, were spending about five times as much.  Other parts of the British empire, again per capita, were spending about eighteen times as much.

Obviously, there is a “small number of British just couldn’t reach those hundreds of millions of Indians in the countryside” effect going on here.  Still, from what I am seeing education simply was not much of a priority.  There was some ruling, some building of infrastructure, and some resource extraction going on.  Education ended up as a side show, and ultimately the gears of empire were attuned toward self-maintenance and that meant only a minimal emphasis on education.

Primary schools were especially weak, as was education for girls, no surprise on either count.  In per capita terms, spending on education in Bombay was ten times higher than in Orissa.

What happened to Alywn Young’s Hong Kong vs. Singapore contrast?

From 1992, the paper is here (note by the way an interesting written comment from Paul Krugman at the end).  The basic story was that Hong Kong and Singapore had obtained their prosperity by two different paths.  Hong Kong had made real productivity gains, but Singapore grew just by throwing more factors of production at the problem of economic growth, including a massive dose of savings and investment, including foreign investment.  The share of investment in Singapore’s gdp rose from 9% in 1960 to 43% in 1984, while Hong Kong’s remained roughly steady at about 20%.  If you back this out from national income statistics, you can measure that Singapore had very low levels of total factor productivity growth.

But should we believe that story, which by now is twenty years old?  After all, these days, Singapore is extremely interested in cutting-edge science and on the frontier in the biosciences and with satellite launches, among other areas.  Hong Kong has done fine, but as a finance center and entrepot for the China trade.  Not many people look to them as ideas leaders.  Maybe both countries somehow turned on the proverbial dime, but I don’t believe the initial Young result for a few reasons:

1. Ever since Michael Mandel, I am skeptical about backing out productivity claims from “value-added” data for extremely open economies.  The quality of the data do not support extremely strong claims, and Krugman stresses this point in his comment.  By the way, in the Singapore data TFP growth is negative in some sub-periods; see pp.24-5, can you believe -8% for 1970-1990?  I take this as indicative of problems in the data and I am not persuaded by Young’s suggestion that it results from cyclical factors.

2. There is much talk about Singapore bringing in so much capital, and they did.  But getting all that capital is not as simple as throwing a switch.  Presumably the capital — especially the foreign capital — comes in part because investors expect a favorable productivity environment, if only prospectively.

3. Sometimes capital can “carry” or “contain” TFP growth; imagine spending money on a new industrial robot.

4. Some of the measured “TFP growth” may in fact reflect underpriced labor, including underpriced labor migrating from the PRC into Hong Kong.  Those workers turned out to be more productive than people were expecting, which creates an apparent TFP residual, and migration of this nature played a larger role in the Hong Kong economy than in Singapore.

5. Young’s measures make him sound skeptical about the future (post-1992) course of economic growth in Singapore, and this has hardly been borne out by the facts.  I wouldn’t call this an explicit or formal prediction of his theory but read the paper and the pessimism seeps through, albeit subtly.  Is this passage (p.32) prescient or a sign of a mistaken assessment?:

Although I have presented evidence earlier, on the remarkable rate of structural transformation of the Singaporean economy, I feel that the words of Goh Keng Swee, Singapore’s Minister of Finance, in March 1970 are equally compelling: “. .. the electronics components we make in Singapore require less skill than that required by barbers or cooks, involving mostly repetitive manual operations.” By 1983 Singapore was the world’s largest exporter of disk drives. By the late 1980s, Singapore was one of Asia’s leading financial centers. As of today, the Singaporean government is targeting biotechnology and, no doubt, with its deep pockets, will achieve “success” in this sector. One cannot help but sense that this is industrial targeting taken to excess.

To flesh out this history, note two further points:

1. Young is long renowned for the care and quality of his empirical work.  He is the sort of researcher who might obsess for six months over a footnote.  That is one reason why he has not produced a greater number of papers.

2. This line of research (there are other papers here) was immediately hailed as successful upon its appearance.  I read it too at the time and simply assumed it was likely to be true.  Even Krugman, despite his insightful worries in his comment, ended up endorsing the Singapore result as true (that link is also an excellent essay for background on this entire set of ideas and debates).

The funny thing is, Young’s hypothesis still could be true.  It hasn’t been refuted.

But if you ask me — I don’t believe it, not any more.  I take this to be a cautionary tale of how difficult it can be to establish firm knowledge through economics.

What is the causal link between parental income and education?

…the connection between income and student performance “is no less true in the Age of Obama than it was in the Age of Pericles.” But, he points out, most of the connection is not causal, but due to other factors.  He cites a study by Julia Isaacs and Katherine Magnuson (Brookings Institution, 2011), that examines an array of family characteristics – such as race, mother’s and father’s education, single parent or two-parent family, smoking during pregnancy – on school readiness and achievement.  The Brookings study finds that the distinctive impact of family income is just 6.4 percent of a standard deviation, generally regarded as a small effect.  In addition, Peterson calls attention to earlier research by Susan Mayer, former dean of the Harris School at the University of Chicago, which also found that the direct relationship between family income and education success for children varied between negligible and small.

Responding to Ladd’s claim that the gap in reading achievement between students from families in the lowest and highest income deciles is larger for those born in 2001 than for those born in earlier decades, Peterson points out that the achievement gap between income groups was growing at exactly the same time the federal government was rapidly expanding services to the poor – Medicaid, food stamps, Head Start, housing subsidies, and many other programs.

“A better case can be made that any increase in the achievement gap between high- and low-income groups is more the result of changing family structure than of inadequate medical services or preschool education,” Peterson says.  In 1969, 85 percent of children under the age of 18 were living with two married parents; by 2010, that percentage had declined to 65 percent.  The median income level of a single-parent family is just over $27,000 (using 1992 dollars), compared to more than $61,000 for a two-parent family; and the risk of dropping out of high school increases from 11 percent to 28 percent if a white student comes from a single-parent family instead of a two-parent family.  For blacks, the increment is from 17 percent to 30 percent, and for Hispanics, the risk rises from 25 percent to 49 percent.

That is from Harvard’s Kennedy School, from Paul Peterson.  Here is more, and for the pointer I thank Ilya Novak.

*Being Global*

The authors are Angel Cabrera and Gregory Unruh, and the subtitle is How to Think, Act, and Lead in a Transformed World.  Cabrera is the incoming president of GMU, as of this summer, so of course I am keen to read this book, which arrived in my pile today.

You can follow Cabrera on Twitter here, among other topics he covers leadership, globalization, and also the Spanish economy.

Is Creativity more like IQ or Expertise?

IQ, whatever its flaws, appears to be a general factor, that is, if you do well on one kind of IQ test you will tend to do well on another, quite different, kind of IQ test. IQ also correlates well with many and varied real world outcomes. But what about creativity? Is creativity general like IQ? Or is creativity more like expertise; a person can be an expert in one field, for example, but not in another.

In a short piece in The Creativity Post, cognitive Psychologist Rober Baer argues that creativity is domain-specific:

Efforts to assess creativity have been plagued by supposedly domain-general divergent-thinking tests like the Torrance Tests of Creative Thinking, although even Torrance knew they were measuring domain-specific skills. (He create two different versions of the test, one that used verbal tasks and another that used visual tasks. He found that scores on the two tests were unrelated —they had a correlation of just .06—so they could not be measuring a single skill or set of skills. They were—and still are—measuring two entirely different things.) Because these tests have been used in so many psychological studies of creativity, much of what we think we know about creativity may be based on invalid data. These tests have also been widely used in selection for gifted/talented programs — programs that have, in turn, often suffered because by assuming creativity was domain general, these programs often wasted students’ time with supposedly content-free divergent thinking exercises (like brainstorming unusual uses for bricks) that really only develop divergent-thinking skill in limited domains.

The metaphor we use for understanding creativity will impact how we train for creativity:

If one’s goal is to enhance creativity in many domains, then creativity-training exercises need to come from a wide variety of domains—just as we must provide a broad general education if we want students to acquire modest levels of expertise in many areas. But if one’s goal is to increase creativity in just one domain, such as one might want to do in a gifted program focusing on one domain (such as a program in dance, poetry, math, etc)., then it would be appropriate for all of the creativity-training exercises to come from the particular domain of special interest.

Baer’s view is controversial. My inclination is to think that creativity does have a significant general aspect because creativity seems so often to involve combining seemingly disparate ideas. My suspicion is that that there is a neurological basis for this in, to put it crudely, right-brain, left-brain communication channels. The fact that creativity can be stimulated by drugs and travel also suggests to me a general aspect. No one ever says, if you want to master calculus take a “trip” but this does work if you are blocked on some types of creative projects.

Nevertheless, Baer’s view is worth thinking about; he gives more detail to his argument in two academic papers here and here.
